Artificial intelligence’s bubblitude fizzes with circular transactions, risk concealment, and exotic real-estate debt finance. In a frenzy to build AI data centers, Big Tech recently borrowed and bonded more money in 11 weeks than in the previous three years combined. More than a thousand new data centers are under construction or planned nationwide. Though they don’t yet know how many of those facilities will eventually materialize, energy suppliers are using AI data centers’ ravenous appetite for electrons to justify vast new investments in gas and nuclear power plants and the revival of uneconomic coal plants, claiming that all are needed to win the AI arms race and keep the lights on.

This trillion-dollar surge is transforming not only equity and capital markets but also the future U.S. power mix, locking in decisions that will shape energy affordability for decades. Smarter, cheaper, cleaner, less-risky options for powering data centers exist — if decision-makers choose them.

To meet all the expected new electricity demand, the U.S. has rapidly proliferated its gas-fired capacity under development in 2025. For context, at the start of 2024, only 4 gigawatts of gas-fired power in the U.S. development pipeline were explicitly earmarked for powering data centers. Today, over 100 gigawatts are.

And developers are proposing to invest over $400 billion to build more than 250 gigawatts of new U.S. gas-fired power plants — nearly tripling the gas power pipeline in a year, mostly driven by speculative AI projects subsidized by 37 heavily lobbied state governments.

Some data centers are even being mandated as ​“critical defense facilities” to be built on federal land, alongside otherwise uneconomical nuclear plants exempted from strict Nuclear Regulatory Commission scrutiny, all at taxpayer expense. This is happening, ironically, in Texas — the nation’s free-enterprise leader in solar, wind, and batteries. These renewable resources totaled 97% of its 2025 capacity additions, while fossil fuels amounted to 3%, and nuclear 0%. But in the past two years, planned gas plants in Texas nearly quadrupled, to 80 gigawatts. Only China has more gas plants under development than Texas, and nearly half the Texas plants are meant to power data centers directly.

We’ve seen this movie before. A quarter century ago, the coal industry warned that the Internet would overwhelm the grid without massive new coal capacity. Demand proved to be over tenfold lower. The dot-com bubble burst in 2000, permanently vaporizing $120 billion of electricity investments and embalming another $80 billion in infrastructure built long before it was needed. Today’s AI mania rhymes: Gas and nuclear vendors that can’t beat energy efficiency and renewables in competitive markets are leveraging hype into mandates and subsidies to rescue their losers.

Yet capital markets increasingly fear that AI looks like a bubble set to pop. That’s because each new data center effectively bets against at least 10 plausible outcomes that make the investment unwise: Scaling large language models could fail to achieve superintelligence; customer revenue could disappoint; inaccuracy may persist; smaller and leaner models might keep outperforming giants; copyright infringements may have to be paid for; data centers may go on quadrupling their energy efficiency every year; and flexible interconnection might stretch existing grid assets to serve all new demand.

Each new power plant also bets against the ways that data centers may access cheaper electricity, such as adding pop-up microgrids, colocating renewables and storage at idle gas plants, and buying efficiency, flexible load, storage, and clean supply from other customers. Betting against any one of these realities is risky. Betting against all of them strains credulity.

Many utilities are already trimming projections toward reality. Regulators in data-center hot spots are scrambling to shield customers from accelerating and politically sensitive rate hikes — already up 16% in Illinois, 13% in Virginia, 12% in Ohio, and 6% nationwide. Meanwhile, actual data-center demand still barely shows up in national totals. U.S. weather-adjusted electricity use fell in 2023, then rose by 2% in 2024, about one-twentieth due to new data centers. Nearly all the growth comes instead from air conditioning, electrifying buildings and vehicles, and reshoring industry. These needs can all be more cheaply met by better efficiency, and by another vast and potent competitor to fossil fuels: renewables.

Globally, data centers — roughly one-ninth of which are devoted to AI — use about 1.5% of today’s electricity. The International Energy Agency forecasts they’ll grow in this decade while renewable supplies grow 11 times more. Thus, solar and wind power, now swiftly displacing costlier fossil-fueled and nuclear power, dwarf the AI boom. Speed to market is paramount for AI developers, so many smart tech companies choose renewables to get their data centers built and running quickly and cheaply.

However, other AI firms have rushed for gas power, and that stampede has doubled gas-plant costs and backlogged gas turbine deliveries to past 2030, to the point that two-thirds of gas-plant project proposals have no named turbine manufacturer. This jam has pushed about a fifth of projects to substitute off-grid gas power, often using adapted aircraft jet engines. These turbine generators are easily available but engineered to meet peak demand, so they’re inefficient, noisy, and dirty. Running them constantly to power data centers would quickly inflate electricity costs and magnify public health damages. U.S. data centers were already projected to cause more than $20 billion per year in asthma and cardiopulmonary disease costs by 2030. Communities will not welcome additional pollution, water stress, noise, and rate hikes.

Gas markets magnify the financial risks of turning to gas to power data centers. New gas wells decline faster than old ones, while falling oil prices can make new drilling and refracking unattractive. At the same time, exuberant exports of liquefied American gas (and gas pipelined to Mexico) are pushing gas toward both global glut and domestic scarcity. The analysts at BloombergNEF predict that new gas-fired AI power could tip the 2025–30 U.S. gas surplus into a deficit, making volatile gas prices for heating, industry, and utilities spike. Indeed, BloombergNEF says wholesale gas futures for 2028–30 are unsustainably priced below production cost. And whatever the gas price, new gas-fired power plants are likely to become underutilized, subsidized assets that burden electricity customers long after today’s AI ebullience fades. While many data centers will be built, many won’t, and many won’t actually run at full tilt for decades to come — stranding gas plants and pipelines built to power them.

Even as national policy reinforces a gas lock-in, power choices that can scale at AI speed already dominate actual markets. Renewables captured over 92% of the world’s new generating capacity in 2024 and (including storage) about 90% of U.S. additions in 2025, with 93% expected in 2026. They are far cheaper than gas power, keep getting cheaper, sell on constant-price contracts for decades, and finance like low-risk annuities. They’re virtually unlimited and deploy at industrial speed.

Last May, China added 1 gigawatt of solar and wind power roughly every six hours around the clock. Pakistan displaced 30% of its utility power with solar in four years. Vietnam added solar equivalent to half of its coal generation in two years. South Australia generates 75% of its annual electricity from renewables and will reach 100% by 2027, driving 37 firms to propose relocating there to secure stable, low-cost power. Global metals giants Rio Tinto and BHP are relying on ​“renewable baseload” power to smelt aluminum and mine copper. Apple’s data centers have run on fully renewable energy for more than a decade. Google just announced that on-site solar, wind, and battery power will get its new 850-megawatt Texas data center online in 18 months, not five-plus years.

Critics have long claimed that variable renewables are too unreliable: The wind doesn’t always blow, and the sun doesn’t always shine. But evidence shows that intermittency concerns are now generally unfounded. Ten proven carbon-free balancing methods already make high-renewable grids reliable and economic in many countries. One of those methods, batteries, costs 96% less today than it did in 2010. BloombergNEF finds that battery-firmed solar and wind deliver steady power more cheaply than any new fossil or nuclear plants, and many operating ones. That’s why three-fourths of India’s new firm capacity today is solar-plus-storage.

Renewables also offer essential speed. In Sparks, Nevada, the world’s largest solar-powered microgrid continuously powers modular data centers. Solar panels laid on desert ground feed hundreds of second-life electric-vehicle batteries joined to form a superbattery. It was all built in four months and delivers electricity that’s cheaper, quieter, and more reliable than grid power; uses virtually no water; emits nothing; and is even portable. This is what clean, scalable, market-speed power looks like. Gas isn’t it.

AI does have some valuable applications. No one yet knows, though, if its revenues can repay the immense and swiftly depreciating investments required. But while markets are answering that trillion-dollar question, the AI boom must not be allowed to undermine American energy affordability and security.

Utilities and regulators can protect existing customers with a simple safeguard, giving teeth to vague qualitative pledges: Sell power to new data centers only under ​“take or pay” contracts that repay the entire electricity investment regardless. Those agreements should be backed by robust bonds or insurance, priced by capital-market risk experts (not by developers), to ensure that if an AI venture collapses, losses fall on the developer, not on households and small businesses.

If markets, and not mandates, determine the outcome, the conclusion is already clear. Gas, coal, and nuclear are too slow, too costly, and too risky to anchor the next wave of U.S. power demand. The only technologies that scale quickly enough, cheaply enough, and reliably enough for AI already dominate global additions. Policy will now decide whether Americans will enable the new energy system or protect the old — and whether they’ll pay for stranded gas plants or profit from the cheapest and most secure electricity in history.

President Donald Trump claimed in his Tuesday night State of the Union speech that Americans worry that ​“we are winning too much” under his administration. That assessment does not apply to everyone in the U.S., judging by recent public opinion polls, but it rings surprisingly true for the clean energy sector in 2026.

Each year around this time, the federal government releases its expectations for new power plant construction. The latest data drop shows clean energy is going to dominate this year, just as it has for many years running. Even as the Trump administration has employed novel and at times legally dubious means to block renewable energy growth, the power sector keeps choosing clean energy again and again — attracted by its low costs, speed to build, and climate and environmental benefits.

This year, solar will provide 51% of the new utility-scale electricity capacity slated to come online, batteries will deliver 28%, and wind will add 14%, according to the U.S. Energy Information Administration. Fossil gas, one of the polluting fuels most supported by the Trump administration, makes up only 7% of that new capacity. Coal, the other polluting fuel favored by the White House, does not appear in the ranks of power plants under construction.

This clean energy success is all the more notable because of the massive amount of total power plant capacity that developers are set to build in 2026: 86 gigawatts, more than the U.S. has ever added in a year. The U.S. constructed 33 GW less in 2025, which was the biggest yearly power plant build-out since 2002. Clean power plants are consuming nearly all of a vastly expanded pie, while gas gets a scant sliver.

Still, gas dominates the existing power plant fleet, producing about 40% of annual generation, compared with less than 10% percent from solar. But the renewable energy source’s odds of dethroning gas improve with each year that solar delivers such a lopsided share of new construction. In California, home to the world’s fourth-largest economy, ascendant solar generation is poised to imminently eclipse the gradually declining portion provided by gas.

The Trump administration’s anti-renewables machinations could slow this trend in coming years. Courts threw out an order to stop construction at five fully permitted offshore wind farms, but an effective blockade on new permits for projects touching federal lands could kill or delay installations that would otherwise get built in the late 2020s. Even so, solar developers hope they can keep the success going by serving the AI sector’s overwhelming demand for quick-turnaround power sources.

Whatever tumult comes after 2026, the U.S. will face the situation with tens of gigawatts of brand-new solar, wind, and batteries in its arsenal.

An energy-affordability bill approved yesterday by the Massachusetts House of Representatives could speed solar permitting, strengthen protections for many electricity consumers, and boost EV charging infrastructure. It could also pull the rug out from underneath the state’s nation-leading energy-efficiency programming.

The legislation, passed in a late-night session on Thursday, takes a wide-ranging approach to combating rising power bills in the state, which faces some of the highest rates in the U.S. What has drawn the most attention, however, is its proposal to cut $1 billion from the energy-efficiency program Mass Save through 2027 in an attempt to lower the fees customers pay to fund it.

Bill sponsor Rep. Mark Cusack, a Democrat, argues that any cuts would target administration and marketing expenses and that Massachusetts would still be spending more per capita on energy efficiency than any other state. Opponents of the measure, though, say it would undermine job growth and slow progress toward the state’s emissions-reduction goals, while doing little to lower electricity costs now or in the future.

“I have to assume it’s going to mean layoffs in the energy-efficiency industry, and it’s going to mean a whole lot fewer heat pumps,” said Larry Chretien, executive director of the Green Energy Consumers Alliance.

Massachusetts has been grappling with rising energy costs for years, but the issue has taken on increasing urgency in recent months. And even in the Democratic-dominated state, the conversation around this bill reflects debates that are happening throughout the region — and the country — about whether to compromise climate and affordability goals for the possibility of savings.

Last May, Democratic Gov. Maura Healey proposed a sprawling affordability package, which received a hearing in June and proceeded no further. In November, Cusack introduced legislation that included many of the measures from Healey’s bill, but also called for slashing the Mass Save budget by $330 million, reinstating incentives for high-efficiency gas heating systems, and making the state’s 2030 emissions-reduction goals nonbinding.

The reaction from consumer and climate advocates was immediate and fierce: The bill would eviscerate the state’s decarbonization progress and do little to help residents struggling with high bills, they said.

Despite these concerns, the Telecommunications, Utilities, and Energy Committee voted in favor of the bill, sending it to the House Ways and Means Committee for further revision. There, lawmakers removed many of the contested measures from Cusack’s original proposal but tripled the proposed Mass Save funding cut, an escalation that has rankled members of the renewable energy community.

“Legislators are feeling the pressure to deliver immediate savings and are cannibalizing programs that actually function to lower electricity costs over the medium to long term,” said Ben Underwood, co-CEO of Boston-based solar company Resonant Energy.

The bill now moves to the state Senate energy committee, whose vice chair Sen. Michael Barrett, a Democrat, has a track record of assertive climate and clean energy action.

Undermining energy efficiency

Mass Save is run by the state’s major utilities according to a three-year plan approved by regulators. Its offerings include home energy assessments, low-cost insulation for income-eligible households, rebates on heat pumps and energy-efficient appliances, and no-interest loans for implementing these measures.

The proposed $1 billion cut represents about 22% of the program’s existing three-year, $4.5 billion budget, but the fallout would be more severe than those numbers suggest. The current budget period runs from 2025 through 2027; by the time a bill could be enacted, more than half of the planned programming would likely have been executed. The $1 billion would therefore come out of a much smaller pool of money, and the impact would likely go well beyond the administrative and marketing costs the bill prioritizes, opponents said.

“It would really, absolutely cripple the program,” said Kyle Murray, director of state program implementation at climate nonprofit Acadia Center.

Such a drastic reduction in funding would trade significant long-term financial benefits for short-term savings, he said. Mass Save spent almost $12.4 billion from the beginning of 2010 through the third quarter of 2025, and generated $42 billion in benefits for the state’s residents and businesses. The fees that fund the program make up roughly 7% to 8% of the per-kilowatt-hour charge on the average electricity bill, which would mean a household with a $200 monthly bill would save little if the fee were lowered.

“It seems like I am most likely going to save $12,” said Mary Wambui, a member of the council that drafts Mass Save’s three-year plan, upon analyzing the impact the legislation would likely have on her own monthly electricity costs. ​“You tell me why a bill should be called ​‘energy affordability’ if it doesn’t do anything for my energy bill?”

The funding cut could also result in lost jobs if business slows down for Mass Save’s network of thousands of home energy assessors and heat pump installers.

Some good stuff

Despite the alarm bells set off by the Mass Save portions of the legislation, other provisions are receiving more support. Solar, clean energy, and climate groups praised the bill’s passage.

The bill calls for strengthening restrictions on third-party power suppliers, which sell electricity directly to customers who don’t want to get their energy from traditional utilities. These companies routinely charge higher prices than default service, often targeting lower-income households, according to studies by the Massachusetts attorney general’s office. The legislation would allow municipalities to ban third-party suppliers from operating in their city or town, limit suppliers’ ability to offer variable rates, and increase the penalties for regulatory violations.

Solar power would also get a boost. The bill would require the state to establish an online permitting platform to speed up the process of municipal approvals for solar projects. It would also allow residents to install portable solar — do-it-yourself kits that send power into a home through standard outdoor outlets — and would double the limit for how much net-metered solar an individual municipality can own, from 10 megawatts to 20 megawatts.

Other bright spots include support for virtual power plants, geothermal networks, and EV charging infrastructure that lets battery-equipped vehicles both consume power and send it back to the grid. Still, advocates say they will now be focusing on defeating the Mass Save funding cuts as the bill moves to the state Senate for consideration.

“If the Senate can fix that, maybe 2026 won’t be so bad,” Chretien said.
