How Tesla Turns EV Sales into Profits When Others Can't

Electric vehicles continue to spark joy for drivers, and yes, that pun is intended. These machines offer smoother rides, more affordable fill-ups, and fresher city air. However, the road toward full electrification remains a winding path filled with unexpected twists. While legacy automakers hit significant potholes throughout 2025, Tesla continues to cruise ahead; meanwhile, the overall market for these vehicles continues to accelerate globally.

Piston Pains and Profit Pitfalls: The Legacy Lurch

The traditional giants of the automotive world placed massive bets on an electrified future, but 2025 brought a brutal reckoning for those investments. Ford slammed the brakes hard; the company recognized a $19.5 billion writedown and associated restructuring charges for their various EV initiatives. Projections for the Ford Model E division suggest ongoing annual losses between $5 billion and $5.5 billion. GM faced its own fiscal fiasco, as it absorbed $1.6 billion in charges resulting from delayed or reduced factory plans. Facilities in Spring Hill, Tennessee, and other locations experienced production halts or significant slowdowns. Volkswagen also wrestled with its own woes, because high investments paired with low returns dragged down their corporate profits.

These troubles stem from a few clear catalysts. Consumer demand in the US dipped slightly after certain tax credits expired, and battery prices remained stubbornly high. Global supply chains buckled under the weight of new tariffs, and competition intensified on a global scale. Many legacy firms leaned back on hybrids and traditional engines to generate quick cash, yet this shift stretched their research budgets thin. Giants that dominated the asphalt for decades now find themselves scrambling like frantic startups. This situation underscores the absolute necessity of agility; a true transition requires bold moves rather than timid tweaks.

Tesla’s Tenacious Tech: Profits in a Sea of Red Ink

Tesla continues to defy the general industry gloom by posting profits while its rivals bleed cash. During 2025, Tesla deliveries reached approximately 1.7 million units; this volume remained roughly flat compared to the previous year. Even with stagnant growth, their automotive gross margins stayed positive because cost cuts and manufacturing efficiency reigned supreme. There are six primary factors that define the edge Tesla holds over its legacy competitors.

The first factor is a classic first-mover advantage. Tesla ramped up its production years ago, and its Gigafactories now churn out millions of battery cells and vehicles annually. By following Wright’s Law, their costs drop with every incremental vehicle produced. Legacy players lag behind with lower volumes; consequently, fixed expenses tend to crush their margins. 

The second factor is vertical vigor. Tesla owns its battery production, software development, and even parts of its material supply chain. This reduced reliance on outside suppliers helps prices plummet. Traditional makers outsource heavily, so they pay a premium during global disruptions.

Public data does not provide an exact percentage for the in-house versus supplier portion of a vehicle’s total bill of materials. However, Tesla utilizes a high level of vertical integration that focuses on expensive components like batteries, motors, software, and power electronics. Batteries alone represent 30% to 40% of the cost of an EV. While legacy automakers like GM and Ford rely more on external partners, GM has attempted to increase in-house battery production via joint ventures. Tesla minimizes external dependency for its core technology; this strategy reduces both costs and risks. Ford remains the most supplier-dependent of the big three, as it purchases battery packs from SK On and sources many powertrain components off-the-shelf.

Vertical Integration Comparison Table

Aspect	Tesla	GM	Ford
Batteries	Mostly in-house cells/production	JV plants (Ultium Cells)	Primarily supplied (e.g., SK On)
Motors/Powertrain	Fully in-house	Increasingly in-house	Mostly supplied
Software	Fully in-house	Mixed (some in-house)	Mixed/supplied
Estimated In-House BOM	~80% (key components)	<50% (growing via batteries)	Lowest (~30-40%)
Strategy	High vertical integration	Moving toward more (via JVs)	Heavy supplier reliance

Tesla’s approach allows for superior cost control and rapid innovation. GM and Ford leverage supplier expertise, but they face higher costs and more dependencies. These figures represent estimates based on industry reports from late 2025, since exact bill of materials breakdowns remain proprietary. 

The third advantage involves platforms that are purpose-built for electrification. Tesla designs its vehicles as EVs from the very first sketch. Other automakers often share platforms with internal combustion models, which means compromises are baked in from the start. Tesla uses Gigacastings to simplify builds and reduce part counts; furthermore, they have optimized wiring through the Etherloop concept. This system improves performance for sensor-heavy cars while simultaneously reducing weight.

Fourth is software savvy. Tesla develops nearly all vehicle software in-house, including the operating system, infotainment, over-the-air updates, and autonomy features. This integration enables rapid iterations and recurring revenue from subscriptions. In contrast, Ford and GM historically relied on suppliers for software; this led to fragmented systems and sluggish updates. Both are shifting toward in-house development, but they trail Tesla in terms of sophistication. The fifth advantage is the direct sales model. Direct-to-buyer stores skip the overhead and fees associated with traditional dealers. Finally, the sixth advantage is simple experience. Tesla has iterated on a single technology for two decades. While Tesla has experts working on materials and battery tech, these technologies often feel like an afterthought at legacy firms.

Reason	Tesla Advantage	Legacy Disadvantage
Scale	Millions produced; economies kick in	Low volumes; high fixed costs spread thin
Integration	Owns batteries, software	Relies on suppliers; pays more
Design	EV-native platforms	Retrofitted ICE setups; inefficient
Sales Model	Direct, software revenue	Dealers, no digital upsell
Experience	Decade of tweaks	Early transition pains

This data tells a clear tale: Tesla turns electrified cars into cash cows, while others treat them as costly calves.

Nascent Nightmares: The Startup Struggle

Newcomers to the industry are not faring much better. Rivian notched minor gross profit wins in late 2024 and 2025, including a $170 million gross profit in the final quarter of 2024. However, full profitability remains out of reach. Cash burns quickly, and new tariffs bite hard into their bottom line. Lucid posted heavy losses in 2025 as operational costs mounted; consequently, Saudi funds continue to prop the company up. Ramps for the Gravity SUV have been delayed, and parts shortages persist.

Both companies embody the difficult "valley of death" phase of manufacturing. Scaling a business sucks up capital, and these firms lack legacy profits from gas vehicles to cushion the blow. Rivian is edging closer to a breakeven point, but Lucid continues to face deeper financial drains. It is an interesting irony that these startups intended to disrupt the industry, yet now they must focus entirely on dodging their own demise. This highlights the rare recipe Tesla perfected; without scale or savvy, these vehicles simply eat money. However, persistence pays off, because cleaner fleets require a diverse set of players.

Future Forecasts: The 2026 Pulse

The world of electrified transport continues to widen wonderfully. Global sales boomed to approximately 18 million units in 2025, which represents an increase of over 20%. Growth was driven primarily by China, Europe, and various emerging markets, although the US market slowed after the expiration of certain credits. While Tesla’s specific market share adjusted to these dynamics, its absolute clout remains firm. For 2026, Tesla is targeting a major takeoff. Core models like the refreshed Model 3 and Model Y are expected to see production growth in the high single-digits or low double-digits compared to 2025 levels. A recovery in demand, price adjustments, and hardware updates will fuel this expansion.

The Cybercab is scheduled to kick off in April, though volumes will be low at first. The Tesla Semi will continue to ramp up, reaching the low to mid thousands. A moderate estimate for total vehicle production in 2026 sits between 1.85 million and 2.05 million units. Expected quarterly production looks like 445,000 in Q1, 500,000 in Q2, 520,000 in Q3, and 570,000 in Q4 (with 20k to 30k errorbars per Q). Significant upside exists if the market rebounds strongly, but risks like competition and autonomy hurdles remain. Affordable models and the growth of the energy division add long-term allure to the brand.

Final Volts: Finding Our Way Forward

The landscape of 2025 offered several sharp lessons. Established giants stumbled under the weight of ambitious bets that met harsh economic realities, and startups burned through cash while chasing a scale they could not yet command. Tesla alone navigated the turbulence with sustained profitability; it proved that early focus, relentless efficiency, and bold integration create durable advantages. These contrasts reveal a deeper truth about the industry. Transitions of this magnitude reward those who commit fully, and half-measures invite heavy costs. Wholehearted execution builds structural moats that others struggle to cross.

The market itself presses forward undeterred. Millions of additional drivers choose electrified options each year for the silence, the savings, and the smoother experience. Production capacity is expanding, new models are arriving, and costs continue their steady decline. Tesla stands poised to capture a meaningful share of this growth in 2026 and beyond, as its structural edges remain intact. Fresh products will join the lineup, and the growth of energy storage adds another powerful lever for the company. It is quite a twist that the legacy automakers were once the behemoths of scaling, yet they now struggle where it matters most. In the end, this shift serves a simple and profound purpose. It moves society closer to reliable and abundant transport. Patience and persistence will carry us toward a future free from fossil fuels.

What to Expect from Tesla in 2026: A Guide to the Autonomous Avalanche

Introduction

2026 marks the year Tesla stops merely leading the electric vehicle industry and starts writing the first chapter in the new book of autonomy. Expect vehicle deliveries climb over 2025's results with Cybercab "deliveries" in the 2nd half of '26. While the vehicle business will still have growth, this is the year of Optimus, robotaxis, Cybercab, and energy hitting with full force. Below, we'll look at what's been announced, what surprises there may be, and one bold prediction for 2026.

Part 1: Announced Plans – The Stuff Musk Has Literally Said

Optimus Gen 3: Robots That Fold Laundry and Your Skepticism

Musk confirmed Optimus Gen 3 prototypes will appear in Q1 2026, with low-volume factory deployment mid-year and thousands rolling out by late 2026. Hands with 22 degrees of freedom, 45 lb carry capacity, and Grok-level conversation skills are locked in. While the full unveil has been teased for Q1 2026, I expect it to be the classic “one more thing” moment at the new Roadster event on April 1, 2026 (assuming it is not delayed again).

Cybercab and Robovan: No Steering Wheel, No Problem

Production of the steering-wheel-free Cybercab is scheduled to begin in 1H 2026 at Giga Texas, utilizing the unboxed manufacturing process. These vehicles are not intended for individual sale; they will go straight into robotaxi service, with the first units likely deploying in Austin. Once these vehicles are licensed and put into service, they technically count as delivered, even if Tesla still owns them. This is true for service loaners and the like too, but Cybercab will be the first time this volume is significant.

Operating cost is estimated at around $0.20 per mile. The 20-seat Robovan follows the steerwheel-free vision (though, in my opinion, we’re not likely to see Robovans on the roads in 2026). Musk says unsupervised FSD will be approved in multiple US states and China by mid-year, with Europe trailing shortly after. This could open these regions up for FSD sales and robotaxi service this year, so let's cover that next.

Robotaxi Service Launch and Rapid Expansion

The ride-hail network launches Q2 2026 in Texas and California the moment regulators sign off, quickly expanding to Vegas. If the fastest way from point A to point B is through a Boring Company tunnel, your robotaxi ride might duck underground to skip surface congestion entirely. Musk still talks about “millions” of robotaxis long-term, but 2026 realistically starts with tens of thousands of Cybercabs plus opt-in owner cars. Owners can earn passive income at roughly 30-40¢ per mile paid to owners. In late 2025, we saw the first unsupervised Robotaxis on Austin streets with no one in the driver or passenger seats. These vehicles were not carrying passengers, but you can expect to see passengers early in 2026.

Roadster 2.0: A One-Second Terror

Reveal locked for April 1, 2026. Sub-one-second 0-60 mph, 620-mile range, optional SpaceX thruster package. Production starts late 2027 at $200,000 USD base. This should be a mind-blowing demo that we get to see this year. 

Semi Factory and Volume Ramp

Tesla held a groundbreaking ceremony in January 2024 for the Semi Factory expansion of Giga Nevada. I expect to see the ribbon-cutting ceremony near the 2nd anniversary of that groundbreaking. 

I expect a meaningful number of Semi customer deliveries in 2026. With production ramping to 50,000 units annual capacity target by late this decade.

Energy Explosion

Megapack 3 and Megablock ship from Houston starting H2 2026. Powerwall virtual power plants expand nationwide in the US. Dry-cathode 4680 cells drop storage prices another 20-30%.

Grok Takes the Wheel: From Chat to Command

Grok 4 turns from 2025's voice chatbot into a full vehicle controller in 2026. Musk confirmed it will set destinations, adjust settings, and open the glovebox. Rollout hits all compatible models by mid-year. More on this below in our Conjecture section. 

Part 2: Conjecture – Logical Extensions That Would Surprise Exactly No One

Vehicle Deliveries Land Around 2.15–2.2 Million (35% Growth)

Core Model 3/Y refreshed lineup carries ~1.7 million units, Cybertruck scales to ~80,000, Cybercab adds ~100,000-150,000 in H2, and Semi contributes low five figures. The unboxed process continues to evolve. Social change at scale is a slow process, limiting growth, still respectable, but unlike many of the 50% plus years that we've seen privious years.

Model	Projected 2026 Volume	Key Notes
Model 3/Y	~1.7 million	Refreshed lineup dominates, Juniper refresh boosts demand in US and Europe.
S/X and Cybertruck	~60,000	Steady Cybertruck ramp at Giga Texas.
Cybercab	~50,000-80,000	April production start, initial Austin deployment, scales throughout the year.
Semi	5,000 - 10,000	Nevada factory enables fleet deliveries to partners like Pepsi.

Model YL Goes Global

The long-wheelbase, three-row Model YL that conquered China in 2025 finally escapes Shanghai. North America gets it in mid 2026 (likely built at Giga Texas), followed by Europe and right-hand-drive markets by year-end. It becomes the practical family hauler that keeps Model Y as the world’s best-selling vehicle.

New Country and Region Expansion

India finally opens fully in H1 with Mumbai showrooms and imported Model 3/Y, followed by Japan’s aggressive retail doubling (10+ new stores). Southeast Asia (Indonesia, Thailand, Vietnam) and Brazil see official launches by mid-year. These markets together add 200,000-300,000 deliveries and plant flags in the next billion-customer frontier.

Model S and Model X Get the Cybertruck Treatment

Fremont finally retires the flagship production in 2026. But not because the Model S and X are being discontinued. Instead, a heavily refreshed Model S and Model X move production to Giga Texas to share the Cybertruck’s platform. This adds steer-by-wire, Etherloop wiring, 48 V architecture, and gigacastings to the S and X. Expect sharper styling, longer range, on this massive refresh. 

So what happens to that space in Fremont? It's quickly repurposed; the freed-up floor space instantly becomes the first high-volume Optimus production line, accelerating humanoid robot production far beyond the initial thousands.

Affordable EVs as the Cybercab Trojan Horse

The sub-$30,000 compact hatch and sedan (we've dubbed "Model Next") emerges as a stealthy sibling of the Cybercab platform. While the two vehicles will share some interior and styling queues, they will be very different vehicles under the skin. It's not just a Cybercab with a retrofitted steering wheel, pedals, four doors, and smaller wheels to slash costs below Model 3. This pivot occurs, not because autonomy fails, but because today, if you want to sell cars, people expect to be able to drive it for themselves when they want to. For deeper speculation, see this analysis on how Cybercab sneaks affordability into Tesla's lineup.

Robotaxi Service Still Becomes a Monster

Even with fewer total cars, a focused fleet of 200,000-300,000 robotaxis (Cybercabs + opt-in owners) could capture 8-12% of US ride-hail miles in launch cities by year-end. Revenue per vehicle proves the margin story long before volume hits absurd levels. 2026 is the year that we'll see robotaxis with passengers and without safety monitors. About 1 year after the safety monitors are removed, we can expect to see Tesla allowing privately owned vehicles to operate as robotaxis.

FSD + Boring Company Tunnels: The Vegas Loop on Steroids

Cybercabs join the mix in the Loop tunnels, but Model Ys will continue to be the primary workhorse in Boring Company projects throughout 2026. New Loop projects in Miami, Austin, and San Antonio break ground for robotaxi traffic.

Cybertruck Wolverine Edition

A narrower, regulation-friendly variant appears late 2026 for Europe and Japan.

AI5 Inference Clusters Inside Every Factory

AI5 samples arrive late 2026, turning Giga Texas and Nevada into edge-inference hubs for real-time Optimus training.

Powerwall 4 Sneaks In

Higher capacity Powerwall 4 with 20 kWh usable and bidirectional charging lands mid-2026.

Grok Gets Grokkier: Proactive and Predictive

Grok starts suggesting detours, syncing with home Powerwalls, and roasting your music taste while quietly optimizing every watt. With full access to the car's cameras via "Grok Vision," it also delivers real-time snark about the people and things you drive past, turning every commute into a running commentary that is equal parts helpful and hilarious.

Giga Mexico: The 2027 Silver Lining

Groundbreaking slips fully to 2027. Permits keep stacking and hiring continues, but no dirt moves in 2026. The million-unit factory waits patiently for its turn in the sun.

Tesla Insurance Reaches 30+ US States

From roughly 25 states today, Tesla Insurance reaches 30 or more by the end of 2026, adding Florida, New York, Pennsylvania, plus two others via self-underwriting and refined Safety Score rules. This covers 2-3 million owners, slashing premiums 20-30% for safe drivers and syncing with FSD discounts. Plus, it's much easier to roll out robotaxi service in areas where they already have a functional insurance business, greasing the wheels for seamless fleet integration.

FSD Expands to More Countries

Unsupervised FSD rolls out in select regions of the US. Namely, to areas where Tesla has robotaxis in service. FSD Supervised moves beyond the US and China to the UK, Netherlands, South Korea, and Japan by mid-2026, with pilots in India and Brazil by year-end. This unlocks robotaxi fleets for expansion into 10+ countries over the coming years, turning global roads into seamless, emissions-free highways.

Tesla Heat Pump: Efficient Home Heating on Hold

Musk has teased a super-efficient residential heat pump since 2020, promising quiet operation and big energy savings to pair with Powerwalls and solar. Tesla already has a lot on their plate for 2026, so I don't expect to see any mention of this. Which is too bad because they could make an amazing product in this space.

Conclusion

2026 is the year Tesla stops being merely the world’s biggest EV maker and starts becoming the backbone of a new energy-and-transport reality. Robots leave factories in the tens of thousands, driverless Cybercabs swarm the streets, Grok turns every ride into a sarcastic joy, and refreshed Model S/X plus the Model YL keep the premium and family segments locked down. Growth lands on top of an already-massive base, yet the real story is the domino effect: cheaper batteries, smarter tunnels, new markets lighting up from Mumbai to Miami, and Optimus turning idle floor space into humanoid-robot gold. The air gets cleaner faster than anyone dared predict, and the planet breathes a very audible sigh of relief. Mexico may wait until 2027, but the rest of the world gets the future a full year early. Bring popcorn, solar-popped of course, and maybe an extra bag, because this show is going to run long past midnight.

The Road Not Taken: Imagine A Century Without Combustion, The Electric Dream

January: a new year, a new chapter, and a time for remembering the journey so far and anticipating the path ahead. Our first month was named for the two-faced god Janus. In this post, one face of Janus gazes back at the early 1900s, when steam, electric, and gasoline vehicles all vied for dominance. Janus' other face peers forward from there, imagining a world where electric vehicles (EVs) prevailed in the early 1900s battle. If the butterfly wings flapped in a different direction a century ago and EVs had become the dominant vehicle technology, this would have completely reshaped the world we inhabit today. On this What If? path, things would be very different today. What lessons can we learn from this, and what could it mean for our future?

In the bustling streets of the early 1900s, automobiles were a chaotic symphony of steam whistles, electric hums, and gasoline roars. Steam-powered vehicles chugged along with bulky boilers, electrics glided silently on nascent batteries, and internal combustion engines (ICE) sputtered along. In this 3-way competition for the future of personal transportation, it was ICE that ultimately claimed victory. Fueled by cheap oil, mass production innovations like Henry Ford's assembly line, and the allure of long-distance travel, the other technologies were outpaced. This ICE dominance steered a century of human engineering prowess and innovation toward refining the noisy, polluting heart of the automobile. While this path brought remarkable mobility, it also locked in environmental costs and global conflict.

The ICE reign sparked countless breakthroughs, transforming a crude contraption into a pinnacle of power. Engineers tackled inefficiencies in fuel use, emissions, and performance, yielding innovations that powered global economies but there are limitations in the physics and chemistry of petroleum combustion that cannot be avoided. Here are several pivotal advancements in the design and control of internal combustion engines.

Advancement	Circa	Key Benefits and Impact
Fuel Injection	1950s	Replaced carburetors for precise fuel delivery, boosting efficiency by up to 15% and enabling smoother starts in cold weather.
Overhead Camshafts (OHC)	1960s	Improved valve timing for better airflow, increasing power output by 20-30% without enlarging engines.
Variable Valve Timing	1980s	Dynamically adjusts valve operation for optimal low-speed torque and high-speed power, cutting fuel use by 5-10%.
Direct Injection	1990s	Sprays fuel straight into cylinders for leaner burns, enhancing economy by 15% and reducing emissions.
Turbocharging	1960s (widespread 2000s)	Forces extra air into combustion for 30-50% more power from smaller engines, aiding downsizing for lighter vehicles.
Engine Control Units (ECUs)	1970s	Computerized oversight of ignition and injection, optimizing performance and enabling real-time diagnostics for 10-20% better efficiency.

These leaps made ICE vehicles more potent and parsimonious, yet they still guzzled fossil fuels and spewed carbon dioxide.

Electric Dreams

Now let's detour to our electric What if? and imagine that electric vehicles (EVs) had prevailed instead.

On this path, EVs, with their quiet elegance and zero tailpipe emissions, had outpaced rivals through better battery advancements, policy nudges, or oil scarcity. That century's worth of ingenuity was poured into batteries rather than pistons. A century of focused R&D would have supercharged battery tech, eclipsing the incremental tweaks of ICE. Today's vehicles would boast specifications that make current models (gas or electric) seem quaint: ranges exceeding 1,000 miles on a single charge, thanks to solid-state batteries or something beyond today's lithium chemistries refined over generations. Acceleration could hit 0-60 mph in under 2 seconds as standard, with regenerative braking recapturing 90% of kinetic energy. Vehicle weights might drop 40% via advanced composites, born from EV-centric manufacturing that prioritized lightweight frames over heavy blocks. And prices? Entry-level sedans could cost under $15,000 USD, as economies of scale in battery production slash costs by 80% from early 1900s levels.

Energy density stands out as the crown jewel of this alternate ingenuity. Real-world lithium-ion batteries hover at 250-300 watt-hours per kilogram (Wh/kg), a far cry from gasoline's 12 kWh/kg effective density. However, with 100 years of undivided attention, EV batteries might reach 1.5 - 2 kWh/kg, rivaling fossil fuels (considering efficiencies) while sidestepping their toxicity. It's important to say that EVs are 4 to 5 times more efficient at turning energy into motion, so 2kWh of battery capacity is effectively worth 8 to 10 kWh of gasoline. This leap would stem from the relentless pursuit of materials like sodium-ion or metal-air cells, coupled with optimized manufacturing. Charging times could shrink to 5 minutes for a full top-up, powered by ubiquitous solar-gridded stations. Ultracapacitors, those quick-charge wonders storing energy electrostatically, would indeed be commonplace. Integrated into every EV, they'd handle burst power for acceleration or regen, extending battery life by 50% and enabling seamless grid-to-vehicle energy trading. Vehicles become rolling power banks, feeding homes during blackouts.

Societally, this EV utopia would ripple profoundly through people's mindsets and attitudes, fostering a regenerative lifestyle. The whole world would be breathing easier. Cities like Los Angeles or Beijing would have never choked on smog, sparing millions from respiratory ills and slashing healthcare costs by billions annually. Air quality improvements alone could boost global life expectancy today by 2-3 years. Using combustion for any purpose would be seen as crude and wasteful. 

Oil's diminished sway in this alternative timeline world would rewrite geopolitics: no OPEC cartels, fewer Middle East conflicts, and trillions of dollars redirected from drilling to renewables and reforestation. Wars might pivot to securing rare earth mines, or not occur at all, as renewable grids democratize energy. Culturally, the romance of the open road is enhanced with silent, scenic cruises and with pop culture celebrating inventors like Tesla as folk heroes rather than eccentrics. Modern challenges, like access to charging in rural areas, are long ago solved.

In reflecting on these paths, the ICE's century of triumphs feels like a detour from destiny, one that moved us forward on the tech tree but scarred the Earth. Undenably, electrification is the ultimate path forward. An EV-led world promises not just superior specs, but a restored planet: clearer skies, and easier breathing. As we stand at another crossroads with climate urgency, embracing electrics now honors that lost electric dream, urging us toward a sustainable, harmonious future.

Rockets, Robots, and Renewables: The 2025 Nobel's Roadmap to an Eco-Abundant World

Innovation's Next Wave: How the 2025 Nobel Insights Illuminate a Sustainable Future

Picture a world where technology breakthroughs aren't just the next device that you have to buy, but something that helps us do more with less. An innovation that can patch environmental gaps and propel economies forward. That is the essence of the 2025 Nobel Prize in Economic Sciences, awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt. Their work spotlights "creative destruction," a concept where fresh ideas dismantle outdated systems to spark lasting growth. Mokyr traces this through history, showing how cultural openness fueled the Industrial Revolution. Aghion and Howitt add mathematical models that demonstrate how research investments trigger innovation cycles to keep prosperity humming. In our time, this plays out vividly in technologies like electric vehicles, autonomous driving, reusable rockets, solar energy, and battery storage. These are not sacrifices for the planet. They are smart bets on abundance. By applying the laureates' lens, we see how such shifts promise cleaner air, lower costs, and broader wealth. On this last day of 2025, let's explore what this prize-winning research says about our future.

EVs do not demand that we give up mobility; they give us a better way.

EVs: Charging With Creative Destruction

Electric vehicles are a textbook case of creative destruction in action. For over a century, internal combustion engines ruled roads, guzzling fossil fuels and churning out emissions. Now, EVs flip the script. Aghion and Howitt's model explains the mechanics: upfront research in batteries and motors yields vehicles with vastly superior efficiency, instant torque, and operating costs under $0.04 per mile, versus $0.13 for gas cars. This erodes the old guard. Global EV sales hit over 9 million in the first half of 2025 alone, claiming 23% of the new light-duty vehicle market. The predictable future shows the supply chains for oil-fueled transportation fading, replaced by battery factories and recycling hubs. Mokyr would nod at the cultural pivot and historical parallels here, much like Enlightenment thinkers embraced steam over sails. Until its demise, policies such as the US Inflation Reduction Act's tax credits nurtured this; drawing in consumers who value sustainability without skimping on performance. The payoff? Trillions in saved energy bills and health costs from cleaner urban air. EVs do not require us to give up mobility. They enhance it, paving roads to growth that respects the Earth.

Autonomous Driving: Navigating a Smarter Mobility Landscape

Autonomous driving takes this disruption to the next level, reimagining a $7 trillion global mobility pie. Human drivers are prone to error. Manual systems keep us chained to outdated controls. Enter AI-guided systems, where sensors and algorithms obsolete steering wheels and fatigue. The laureates' Endogenous Growth theory fits perfectly: iterative software upgrades slash accident rates by up to 90%, unlocking robotaxi fleets that could halve urban transport expenses. The autonomous vehicle market is projected to soar past $4 trillion by 2034. Mokyr's historical echo rings true in the institutional tweaks, like updated traffic codes mirroring 19th-century rail regulations. Freed from the wheel, people reclaim hours for creativity, rest, recreation, or work. Fewer crashes mean healthier people. Environmentally, fewer crashes mean less wreckage in landfills, and optimized routes cut fuel waste by 20-30%. Self-driving cars destroy jobs in traditional driving roles but births roles in data ethics, fleet management, and new roles that are yet to be invented. Autonomous tech whispers a greener commute, one where safety and efficiency dance in harmony.

Reusable Rockets: Launching a New Era of Orbital Access

Reusable rockets, trailblazed by SpaceX, hurl us into orbital economics with gusto. Throwaway launches once made space a luxury for only governments, costing $10,000 per kilogram to orbit. Now, Falcon 9's landings and Starship's visions drop that to around $100 per kilogram. Aghion and Howitt's waves of innovation capture this: each reuse refines designs, obsoleting expendable rivals and slashing mission prices by 100 times. The space economy, valued at $570 billion in 2023, eyes $2 trillion by 2040, fueled by satellite swarms for climate monitoring and global connectivity, space-based energy harvest, space-based compute, Lunar bases, and Mars gateways. Mokyr may highlight this affordable space access as a cultural enabler, akin to patent booms that shielded early inventors. Private players thrive, spawning Earth-observing tools that track deforestation or ocean health in real-time. No longer sporadic feats, space becomes routine progress.

When an alternative is better and cheaper, things change quickly.

Solar Energy: Harnessing the Sun for Endless Power

Solar energy turns the tables. Fossil plants, with their fuel bills and smoke stacks, held sway for generations. Photovoltaic panels change that, harnessing sunlight at costs that plunged from $7.50 per watt in 2010 to under $0.30 today, a drop exceeding 96%. The laureates' model illuminates why: R&D in perovskites and trackers spawns better PV systems, making coal uneconomic. Grids decentralize, with rooftops turning homes into mini-generators and cutting transmission losses by 7%. Mokyr draws parallels to the eclipse of whale oil by kerosene. When an alternative is cheaper and better, the market responds, and change happens. By mid-century, solar energy could supply 50% of global electricity, saving $1.5 trillion annually in fossil fuel imports. This is environmental elegance: boundless rays yield clean electrons, fostering growth that leaves waterways and skies untouched.

Battery Energy Storage: Stabilizing the Grid for a Brighter Tomorrow

Battery energy storage seals the renewable deal. Batteries tame solar and wind's intermittency without dirty backups. No more need for emission-spewing peaker plants. Now, lithium packs dispatch power on demand. Aghion and Howitt's cycles explain the surge: scale drives chemistry tweaks, like more affordable, highly stable LFP cells that outlast rivals and are more easily recycled. This obsoletes gas turbines, enabling virtual power plants that shave peaks and save $150 billion annually by 2030. Mokyr spots parallels in early telegraph communications aiding railroad coordination; one new technology enabling another. Another example is EVs buffering the grid via vehicle-to-grid tech, making the large EV battery have a dual purpose, and weaving energy storage into our daily life. The result is a robust grid with smooth renewable integration by batteries that buffer weather whims and bolster biodiversity by reducing mercury emissions.

Aligning with Tesla's Master Plan 3: A Blueprint for Sustainable Scale

These threads weave neatly into Tesla's Master Plan 3, a 2023 blueprint for sustainable energy. It maps electrifying transport, heat, and industry on renewable backbones, demanding 50% less material than fossil paths. The laureates' destruction fits Tesla's battery ramp-up, where cost curves mirror Aghion-Howitt math for self-sustaining loops. Mokyr's cultural nod aligns with grid upgrades embedding renewable norms, redirecting industrial legacies toward abundance. Tesla catalyzes this, proving innovation scales without scarcity.

Echoing the CarsWithCords.net Vision: Green Abundance Without Compromise

We echoed many of these same ideas in our 2022 post "Green Abundance: No Sacrifice, No CO2." In fact, we even had the same historical whale oil example as the laureates. That post champions zero-emission living via top-tier tech. It spotlights driving a Tesla as proof that EVs beat gas without trade-offs. This mirrors the Nobel thesis: superior goods spur adoption per Wright's Law, enabling Jevons Paradox to ignite abundance engines. Mokyr's work shows that subsidies can jumpstart nations to clean paths. Both our vision and the laureates' vision shun restraint for smart abundance, uniting on policies that promote prosperity without destroying the planet.

Conclusion: Riding the Wave Forward

In wrapping up, the 2025 Nobel reminds us that true progress pairs ingenuity with care for our shared home. The US manufacturing credits for building renewable infrastructure are about jobs, but they are also building a progress-focused culture. EVs, autonomy, rockets, solar, and batteries are not a distraction. They are the new engines of growth, destroying waste while building resilience. Backed by Mokyr's history, as well as Aghion and Howitt's models, these real-world strides promise a world richer in options and lighter on the land. We stand at the cusp. By championing such creative waves, we craft economies that thrive, not despite innovation. The path forward gleams with cleaner, greener possibilities, inviting us all to ride the innovation wave to a future free from fossil fuels.

Tesla 2025 Lookback

Peering Back at My Tesla 2025 Crystal Ball

About a year ago, I sat down with a steaming cup and a healthy dose of optimism to sketch out Tesla's possible 2025 roadmap in this post. As someone who's long championed electric vehicles for their role in slashing tailpipe emissions and bolstering energy independence, I decided to put on my Carnac the Magnificent costume. 

I took swings at Optimus, vehicle refreshes, Cybercab and even the affordable "Model 2." So how'd I do? As the saying goes, "Prediction is very difficult, especially about the future." This is especially true when trying to predict Elon Musk's timelines. Fast-forward one year to today, in December 2025, and it's time for a candid scorecard. My batting average? Roughly 60-70% on the big swings. Some predictions landed with the smoothness of a Highland Model 3; others slipped like Optimus stepping on a banana peel. Let's unpack the hits, the near-misses, and the flat-out flops.

Vehicles: Refreshes Rock, But Newbies Notch Delays

Tesla's lineup continued to evolve in 2025. I was betting on a new affordable model (called Redwood) to shake up the EV scene and boost volumes. That didn't happen (in 2025). Robotaxis are great, but affordable personal cars will have a significant place in sales rankings for another decade or two, and this is not a segment that Tesla will want to cede to others like the Bolt and LEAF.

Prediction	Outcome	Score
Redwood: Compact crossover production starting mid-2025 at ~$25,000, 225+ mile range on 54 kWh LFP battery, NV9X platform, AI5 hardware, minimalist interior, scaling to 10,000/week at Giga Texas/Shanghai.	Redwood production didn't happen, and it is not part of Tesla's public roadmap.	Total miss. You can expect to see this again in my 2026 prediction list.
Roadster: Redesigned unveiling in August 2025, possibly tied to AI Day or Redwood event.	Delay on the unveil; it's now slated for April 1, 2026, with production whispers for 2027. It's still planned, but no shiny reveal yet.	Flop city. This flying roadster remains the eternal tease, but when it drops, it'll redefine zero-emission speed demons.
Juniper (Model Y refresh): Launch deliveries in March 2025 (US/China first), with 3% range boost, lighter weight, power-fold rear seats, power frunk, ambient lighting, front-bumper camera, second-row screen, improved suspension, & larger frunk.	Delivered bang-on: China and US rollouts hit March, packing a 3% range bump (up to 320+ miles), aero tweaks for lighter curb weight, front bumper camera, power frunk, tuned suspension, and a beefier frunk. Ambient lighting and fold-flat seats shine; no second-row screen, but the full-width taillight bar steals the show.	Bullseye. This facelift turned the Model Y into an even slicker daily driver, coaxing more miles from each charge and keeping EV adoption humming.
Model S/X: Survive as halo vehicles with potential refresh (lush interiors, noise-dampening, smoother suspension, price hike); re-add turn-signal stalk, ambient lighting, power seats/frunk/doors, front camera; free lifetime Supercharging/connectivity; Grok integration premiere then 3-6 month fleet rollout; 48V battery, Etherloop, steer-by-wire, and a price increase.	June refresh brought quieter cabins via better dampening, air suspension tweaks for silkier rides, front bumper camera, Frost Blue paint, and up to 410-mile range on the S Long Range. $5,000 hike (S at $84,990; X at $89,990). Free perks persist; Grok rolled fleet-wide mid-year. No stalk revival, ambient lights, or confirmed 48V/Etherloop.	Solid partial. The price increase and Luxe Package are exactly what we called for. The S & X are Veblen goods. The refresh gave them a needed update. I overshot with 48V and other items that they don't have yet. Still, they anchor Tesla's premium EV perch.

Autonomous Driving and Services: Supervised Steps Forward

Autonomy was my moonshot bet, envisioning robotaxis zipping through Austin and Vegas with minimal human meddling. Reality served a supervised starter pack, which still edges us closer, but less than our forecast. Testing in Austin launched in June with Model Ys, safety monitors in the vehicle, and remote ops for tricky spots with FSD training gobbling up intervention data. The Bay Area, not Vegas, was next on the list. However, Vegas got the nod via Nevada permits in September 2025, so it will be there soon. Partial credit: Foundations firm, but scaling's a slow burn.

Production and Manufacturing: Semi Scores a Win

Heavy hauling is vital for environmental impact, and boy, did it deliver. Semi engineering wrapped early; Giga Nevada's 50,000-unit factory neared completion by November, with first builds trickling by year-end and full ramps in March 2026. Southwest US Megawatt chargers sprouted; DHL piloted 5,000+ km runs in California, while PepsiCo and global testers joined the fray. These beasts promise to decarbonize trucking one silent mile at a time. Let's hope this momentum continues in 2026.

Robotics: Optimus Stumbles, But Strides

I foresaw 3-5k Optimus units in factories by late 2025, as well as demoing flair at events. Optimus made big strides in 2025 (figuratively and literally). It was handing out popcorn at the Tesla Diner opening and candy on Halloween. Optimus learned kung fu to fight Jared Leto and was making full-stride jogging maneuvers by the end of the year. Optimus Gen 3 unveil has been teased for Q1 2026. 

Energy and Infrastructure: Diner Delights, NACS Nailed

My infrastructure ink focused on fun and flow. The 50s Diner (aka Rock-n-Charge) flipped open in July at West Hollywood's 7001 Santa Monica Blvd: 24/7 retro vibes, 80 V4 Superchargers, 250+ seats, giant screens, and Optimus swag. Route 66 nostalgia meets fast charging. Spot-on. And NACS? A triumph. 2025 models from BMW/Mini/Rolls-Royce, Ford, GM, Polestar/Volvo/Nissan packed native ports; Mercedes hopped in February, majors by summer. Stellantis lags to 2026, but 28,000+ Superchargers now welcome all EVs. This interoperability turbocharges EV accessibility, one plug at a time.

Crystal Ball Retrospective: Hits, Misses, and Mileage Ahead

Looking back, my prescient prognostications shone on refreshes like Juniper and infrastructure icons like the Diner, which kept Tesla's ecosystem electric and inviting. The Semi and NACS adoption occurred as planned, paving the way for broader battery adoption and cleaner logistics. Misses? Redwood's tardy trot and Roadster's vanishing act highlight Tesla's pivot to AI over assembly lines, a classic Musk maneuver that amuses as much as it frustrates. Optimus and robotaxis inched forward under supervision, reminding us innovation's a marathon, not a microwave meal.

Despite delayed timelines, 2025 demonstrated Tesla's inherent ability to deliver sustainable surprises. As we charge into 2026, I'm bullish: More EVs on roads mean quieter cities, cleaner air, and a planet breathing easier. My 2026 forecast is coming soon. What would you like to see in it?

U.S. Clean Tech in 2025: Record Deployment Amidst Legislative Turbulence

The Year 2025: A Shock to the System

The year 2025 was a period of high-voltage whiplash for the US energy sector. It was a time when record-breaking progress collided with political U-turns. We saw the renewable industry sprint to the finish line as federal incentives evaporated like solar production when the clouds come out. Simultaneously, the industry was facing a wall of new legislative hurdles; yet, if you were a solar installer, you likely had the busiest year of your life. If you were an offshore wind developer, you probably spent 2025 updating your resume. The contradictions were sharp. The US became a manufacturing powerhouse for clean technology just as the government pulled the rug out from under consumer incentives. It was the best of times for batteries; it was the worst of times for wind turbines.

The Solar Coaster and the Storage Surge

Solar energy had a banner year in 2025. In fact, it was almost too successful for its own good. Solar and battery storage accounted for a massive 81% of all new power capacity added to the grid. When you zoom out to include other renewables, that figure reached 93% through September. The driving force behind this frenzy was not just altruism; it was panic.

Homeowners rushed to install panels before the expiration of the Residential Clean Energy Credit. This 30% credit, a staple of the industry known as Section 25D, was terminated at the end of 2025 by the new administration. The result was a "going out of business" sale atmosphere that kept installers on roofs from dawn till dusk. California led the charge. The state achieved a milestone that once seemed impossible. For nearly every day in 2025, clean energy sources provided 100% of the state's power for at least part of the day.

Batteries were the unsung heroes of this transition. Operating storage capacity jumped by 32% by October. This was not just about saving money; it was about survival. As extreme weather battered the grid, thousands of Americans turned to microgrids to keep the lights on. The resilience narrative finally overtook the environmental narrative. People just wanted their refrigerators to run during a blackout. A battery-powered renewable grid is a more reliable grid.

The Wind That Failed to Blow

While solar soared, wind energy crashed. The sector faced a perfect storm of rising interest rates, supply chain snarls, and political hostility. The lowlight of the year was the executive freeze issued in early 2025. This presidential memorandum paused all new leasing on the Outer Continental Shelf. It sent a chill through the market that no amount of hot air could warm up.

The trouble was not limited to US waters. The cancellation of major projects served as a grim warning sign for domestic developers. It signaled that the economics of offshore wind were becoming untenable without significant government support. In the US, investors took the hint; capital fled the sector. Projects that were once heralded as the future of the Eastern Seaboard were quietly shelved or cancelled.

The Corporate Casualty List

The financial strain of 2025 claimed some big scalps. The residential solar model, which relied heavily on cheap loans and generous tax credits, buckled under pressure. The most notable casualty was Sunnova. The residential solar provider filed for Chapter 11 bankruptcy in June 2025. It was a sober reminder that rapid growth does not always equal sustainable profit.

Lending institutions also felt the pain. Mosaic, a major player in solar financing, faced similar existential threats. These bankruptcies cast a long shadow over the industry. They left customers wondering who would service their panels; they left investors wondering if the rooftop solar boom was a bubble waiting to burst.

The EV Tax Credit Tragedy

For electric vehicle enthusiasts, 2025 was a heartbreak. The year started with promise but ended in disappointment. On September 30, the federal EV tax credit was eliminated. This cut effectively raised the price of a new electric car by $7,500 overnight. Sales in the fourth quarter plummeted as buyers were priced out of the market.

However, the infrastructure story was surprisingly positive. 2025 saw a record number of high-speed public chargers installed across the US. The network finally began to look robust enough for the average driver. We also saw a cultural shift; electric vehicles became more visible in media as normal household appliances rather than political statements. It was a small victory in the culture war, but a victory nonetheless.

The One Big Beautiful Disaster

The defining political event of the year was the passage of the One Big Beautiful Bill Act (OBBBA) on July 4. This legislation was a sledgehammer to the previous administration's legacy. It rolled back key provisions of the Inflation Reduction Act and introduced strict new rules on foreign supply chains.

The OBBBA established a Prohibited Foreign Entity (PFE) regime. This rule penalized projects that sourced components from countries like China. While the goal was to boost domestic manufacturing, the immediate result was chaos. Developers scrambled to find compliant parts. Many found that US factories, while growing, could not yet meet the demand.

The 2025 Energy Scorecard

Metric	2020 Status	2025 Status	Trend
New Power Capacity (Renewables)	~70%	93%	Surge
Federal Solar Tax Credit	26%	0% (Expired 12/31)	Eliminated
Electricity Prices	Baseline	+35% vs 2020	Spike
US Solar Manufacturing Rank	14th Global	3rd Global	Boom
Heat Pump Sales	Niche	Outsold Traditional ACs	Shift

The Gridlock on the Grid

Perhaps the most frustrating lowlight of 2025 was the interconnection crisis. We built the power plants; we just could not plug them in. The queue to connect new projects to the grid grew longer and slower. Outdated transmission infrastructure struggled to handle the load.

Electricity prices hit record highs in 2025. Rates were up 35% compared to five years prior. Utilities blamed inflation and grid upgrades; consumers just blamed the utilities. This price hike added insult to injury for ratepayers who were already dealing with the loss of solar incentives.

A Spark in the Dark

The year 2025 proved that the energy transition is not a straight line. It is a jagged path filled with obstacles and detours. Yet, despite the legislative setbacks and corporate bankruptcies, the fundamental shift continued. We saw US manufacturing reborn; we saw heat pumps become the default choice for heating and cooling; we saw the grid get cleaner and more stable, even if it became more expensive.

The momentum of technology often outpaces the slow march of policy. Solar panels are cheaper than ever; batteries are more efficient. The public desire for energy independence is stronger than any tax credit. As we move beyond this turbulent year, the destination remains clear. The road is bumpy, but we are still heading toward a future free from fossil fuels.

Tesla 2026: Cybertruck Could Transform Model S and X

Tesla’s Potential Large Passenger Vehicle Platform: A Unified Future for Model S, Model X, and Cybertruck

Tesla’s Cybertruck has a bold appearance that's unlike pickups of yore. Cybertruck's boldness continues under the surface as well. Traditionally, vehicles use miles of wire to connect everything to a Controller Area Network (CAN) bus. Cybertruck scraps that and opts for a faster network, which they call Etherloop. This uses about 68% less wiring. Munro & Associates) reports ~73% overall wiring weight reduction in Cybertruck compared to prior Tesla architectures.

Similarly, Cybertruck uses a 48-volt auxiliary power system. This offers significant advantages, including improved efficiency and reduced weight by using thinner wiring. The higher voltage supports more powerful electrical systems, such as enhanced lighting and infotainment, while reducing the need for multiple low-voltage batteries. It also simplifies steer-by-wire.

These innovations cannot stay exclusive to the Cybertruck. They must proliferate throughout Tesla's vehicle lineup. The fastest way forward for this proliferation would be the bold step of unifying the Model S, Model X, and Cybertruck on a shared platform based on the Cybertruck’s architecture. This would create Tesla's new large passenger vehicle platform. It would streamline production for these vehicles, reduce costs, and bring cutting-edge technology to Tesla’s flagship models. 

We'll explore the advantages, implications, manufacturing location, and timeline for such a platform and redesign, along with the potential for features like four-wheel steering to enhance the Model X.

Advantages of a Shared Platform

A unified platform would allow Tesla to standardize components across the Model S, Model X, and Cybertruck. Shared parts could lower production costs through economies of scale, as Tesla would purchase components in bulk. Manufacturing would become more efficient, with simplified assembly lines and reduced setup times. The Cybertruck’s 48-volt architecture, steer-by-wire, and Ethernet-based wiring system would modernize the Model S and Model X, which currently lack these features. Additionally, steer-by-wire tech would enable right-hand drive variants, which Tesla discontinued for Model S and X in 2023. This would reopen the UK and Australian markets to the S and X.

A shared platform for Model S, Model X, and Cybertruck means shared components and architecture. It does not mean a similar exterior design for all three. The Model S and Model X would not adopt the Cybertruck’s angular stainless steel exterior. The Model S and Model X would utilize the Cybertruck’s 48-volt system and steer-by-wire technology, rather than its aesthetics. Their sleek, curved designs would be preserved.

Implications and Manufacturing Locations

A shared platform could reshape Tesla’s production strategy. Currently, Model S and Model X are built at the Fremont factory in California, while the Cybertruck is produced at Gigafactory Texas in Austin. A unified platform would likely lead to consolidated production at Gigafactory Texas. A shared platform would also support adding four-wheel steering to the Model X, complementing its falcon-wing doors, making the X even cooler.

Shared Production Line

A shared platform would allow Model S, Model X, and Cybertruck to share a production line. A typical production line produces 100,000 to 250,000 vehicles annually, depending on automation and model complexity. The vehicle mix on a shared production line could be adjusted based on demand, enabling flexibility for Tesla to optimize and respond to market shifts for these three relatively low-volume vehicles.

Timeline for Redesign

The Model S and Model X received major refreshes in 2021, with minor updates in June 2025, adding features like a front bumper camera and improved interiors. Tesla’s typical refresh cycle spans 5-7 years, so a major redesign in 2026 fits this pattern. A major platform overhaul that brings all of Tesla's latest and greatest tech to their flagship vehicles would be exciting.

Manufacturing and Feature Summary

Aspect	Details
Current Manufacturing Location	Model S/X: Fremont, CA; Cybertruck: Austin, TX
Potential Manufacturing	Likely Gigafactory Texas on shared platform
Last Major Refresh	S/X 2021 (interior, powertrain updates)
June 2025 S/X Update	Front bumper camera, new wheels, enhanced interiors, new paint colors
Proposed Features	48V architecture (all), steer-by-wire(all), four-wheel steering (CT and new for Model X)
Right-hand Drive Variants	Currently unavailable for S/X; possible with new platform; (Re)opens regions
Redesign Timeline	Speculatively Sept 2026

Conclusion

A large passenger vehicle platform based on the Cybertruck could transform Tesla’s Model S, Model X, and Cybertruck production by reducing costs, unifying technology and production lines, while enabling right-hand drive variants. Manufacturing would shift to Gigafactory Texas. The refresh cycle history hints at 2026 as the year this redesign could happen. Adding a four-wheel steering option to Model X would elevate its appeal, making it a standout in Tesla’s lineup.

Tesla 2025 Solar Powerwall Year In Review

Each year, Tesla gives you a bunch of solar and Powerwall stats. You also get to see community stats and where you land in the pack for some of them. They also give you a title or category depending on how you use your system. My title is on the final image below. 

Saving money is not the primary reason that we bought solar and Powerwalls, but once we had them, I certainly tried to maximize this aspect. 

509 years is quite the smartphone charge.

Jog for 2 years, but at what speed? 🏃

I am really surprised that we're even in the top half for solar production. We're in rainy Oregon, and we have east/west-facing panels.

StormWatch mode is one of my favorite features of the Powerwall. If the grid goes down, my lights (and heat) don't go out.

4.5MWh is enough to power a small community during an outage. This much energy could supply electricity to about 400-500 average US homes for a full hour during peak demand, or around 150 homes for a whole evening (assuming ~30 kWh daily use per home). Of course, in my case, this energy was spread out over the year.

Our lowest consumption days tend to be in the Spring and Autumn, when the heat pump does not need to heat or cool our house. 

Our highest energy usage days are typically in July or August when the AC has to run for several hours each day. So why was June 9th our big day in 2025? This was a VPP event day. Our local utility sucked 32 kWh from our Powerwall along with all the surplus solar that we could generate during the event. 

There are over a thousand peak hours each year on our TOU energy schedule. Solar covered 16% of it, Powerwalls covered the bulk (57%), leaving just 27% for the grid. For 2026, the Powerwall coverage should be even higher since we had a new TOU schedule starting on January 1st, 2025 and the Powerwall was slow to adjust to the new schedule (despite the fact that I put the new rate schedule in on Jan 1st).

 

Congratulations, you've made it to the end, so you get to see that our title for 2025 is Trickster. We don't use our Powerwalls in the boring stand-by only mode or the straightforward self-power mode. Instead, we time-shift to use solar to cover the peak hours and use off-peak charging in the winter to supplement this. This is a win-win; we get more affordable energy, and the grid gets to offload our demand during peak time and deliver more during off-peak when there's plenty of capacity available. ♕

Low Rolling Resistance Tires: A Decade of Scientific Advancements

Introduction

Back in 2015, trying to find definitive data on a tire’s Coefficient of Rolling Resistance (Crr) felt like an archaeological dig. Consumers like me were left squinting at vague marketing promises like "Fuel-Saver," hoping the ambiguous language meant they would not sacrifice too much range or performance. Fast forward to today, and while the industry still harbors a few secrets, the overall landscape for Low Rolling Resistance (LRR) tires has improved dramatically. Regulatory shifts and the quiet, crushing demands of high-torque electric vehicles (EVs) means that LRR technology has moved from a niche offering to a foundational pillar of modern mobility. Reducing rolling resistance (the energy lost to tire deformation) is simply smart science, and the market now rewards drivers who seek efficiency, longevity, and superior structural strength.

Silicon Secrets and Structural Shifts

The biggest gains in LRR technology stem from breakthroughs in material science, which is a surprisingly rubbery and complex field. The secret sauce is largely silica, specifically Highly Dispersible Silica (HDS). When mixed with specialized synthetic elastomers, HDS significantly reduces a tire’s internal friction, or hysteresis. Less friction means less heat, which means less energy wasted when the rubber flexes against the road.

Manufacturers are also experimenting with structural innovations. Some companies, for instance, are leveraging large-diameter, narrow-width designs coupled with higher inflation pressures. This concept, sometimes called "ologic," effectively reduces the contact patch's deflection, providing a superior blend of lower rolling resistance and improved aerodynamics. This careful engineering ensures the tire maintains safety and satisfactory wet grip, preventing LRR from becoming a frustrating trade-off for braking power. The push for more durable and efficient compounds has also opened the door to sustainable alternatives, with some research focusing on non-petroleum-based rubber additives.

Data Disclosures and Dollar Savings

The days of relying solely on a tire salesperson’s cheerful assurances are waning. While the US still lacks a unified federal standard for replacement tire labeling, the influence of comprehensive systems, such as the European Union’s tire label that mandates rolling resistance ratings, has elevated consumer awareness globally. Today, consumers have access to third-party testing and specialized online reviews, allowing for meaningful comparisons that simply were not possible a decade ago.

The economic case for LRR is compelling, often outweighing the slightly higher initial purchase price. For the average passenger vehicle, switching to a high-quality LRR tire typically improves fuel economy by 1% to 5%. This might sound modest, but for high-mileage drivers or fleet operators, the compounded effect is substantial. Consider the potential long-term cost recovery:

Fuel Savings Factor	Estimated Average Fuel Economy Improvement
Passenger Vehicle	1% to 5%
Reduction of Vehicle Road Load	10% reduction in Crr yields ~1.6% fuel savings
Long-Term ROI	Fuel consumed by a standard tire over its life can cost several times its initial $ price

As the global market for these superior tires is projected to reach $20.5 billion, competitive pricing ensures that these innovations are readily available. Buyers can now prioritize tires that offer a happy marriage of low resistance and long tread life, maximizing their savings at the Supercharger (or at the pump).

Conclusion

The journey from vague "eco" promises to quantified, performance-backed LRR tires has been swift. What was once a mystery wrapped in a flimsy marketing brochure is now a sophisticated, silica-enhanced product that tangibly benefits the driver and the environment by maximizing efficiency. Choosing a modern LRR tire is not just a gesture of environmental friendliness; it is a fiscally responsible decision that pays dividends over the lifespan of the rubber, saving you cash and improving your range. We'll see if there's a 2035 follow-up on the state of LRR tires here on CarsWithCords.net.
