Data Centers’ Dirty Diesel, Alaska’s Gas Crisis Continues, CARB Backtracks on Insurance
1. Virginia Data Centers Ran On Dirty Backup During Air Quality Crisis
Local officials are calling for new regulations after a massive data center switched onto diesel generators during an air quality emergency.
As smoke from Canadian wildfires created a Code Red air quality alert around Washington, D.C. last week, a Northern Virginia data center switched onto its dirty backup diesel generators.
The data center in question is the Vantage VA2 Campus, an “unusual” data center campus normally powered entirely by a set of off-grid gas generators, with diesel backup. Research showed that this data center alone could result in up to $495 million in health-related damages over a five-year period.
Data centers’ backup generators are already significant contributors to local air pollution, even outside of air quality emergencies. Records of air permits in Virginia show that diesel backup generators are permitted to emit tens of thousands of tons of localized air pollution, on top of their carbon emissions.
The use of backup generators is especially important in the design of policies incentivizing data center demand flexibility, as absent clean energy requirements, flexibility can mean a switch to diesel generators, threatening local health.
Northern Virginia resident Greg Pirio, on backup generators running to power data centers: “When they’re going off, I know when they’re going off, not only because it’s even louder, it’s because my lungs start hurting me. That’s what we’re living with here.”
2. Elon Musk Quietly Buys Gas Generator Maker To Power Data Centers
In quiet regulatory filings, Elon Musk revealed he spent $1 billion on a fossil fuel generator company to power xAI.
According to case documents with the FTC, Elon Musk quietly bought APR Energy, a mobile fossil fuel generator company, for $1 billion. The company makes mobile gas and diesel generators, including some used to power data centers.
Musk’s xAI has flagrantly broken critical emissions and energy regulations by running unpermitted gas turbines at its Colossus 1 and 2 data centers in Tennessee and Mississippi, respectively. It has only been able to continue doing so with the support of the federal government. xAI and Musk’s use of fossil generation is a stark reversal from his previous public profile as a clean tech booster.
xAI’s use of fossil fuels to power its data centers and its contribution to localized harmful pollution is at the center of anti-data center backlash. Though not all companies are flagrantly violating clean air regulations, most are creating substantial increases in their emissions — and seeing significant public backlash as they rush to connect dirty generation to power their facilities.
3. Alaska Utility Warns It Will Run Out of Gas for Winter
Alaska utility Enstar warns it doesn’t have enough reserves to serve customers through the winter as Cook Inlet gas dwindles.
Alaska’s Enstar warned regulators that its gas reserves are “not looking good” ahead of the winter, as its main source of natural gas, the Cook Inlet, is dwindling in production. State regulators also rejected a $240 million proposal from Enstar to expand a natural gas storage facility, adding $10-12 per month to customers’ bills.
Southern Alaska has been searching for solutions to its looming gas crisis as reliance on fossil gas becomes dangerous as Cook Inlet runs out of extractable gas. Alaska Governor Mike Dunleavy alongside the Trump Administration also pushed for a massive $55 billion pipeline to connect the region to North Slope gas reserves via an 800-mile pipeline, largely for export.
While some, including lawmakers and Enstar, have floated the Glenfarne pipeline as a solution to the gas shortfalls, the developers have not made an official investment decision yet, and have asked for multi-billion dollar tax giveaways to make the project happen. Meanwhile, local clean energy projects that would have contributed crucial capacity have been slow-rolled or canceled.
4. Greg Abbott Floats Roof Fortification
The Texas Governor wants to create a new fortification and resilience program as climate disasters drive insurance costs up.
As part of a broader affordability plan, Texas Governor Greg Abbott is proposing a $400 million program to install storm-resilient roofs across the state. According to Abbott, a notorious climate denier and booster of fossil fuel resources, “extreme weather events” are driving costs for Texans.
Texans are facing some of the highest climate-driven cost increases in the country: insurance premiums have risen 55.9% in Texas since 2020, and Lone Star homeowners pay, on average, $6,000 in premiums annually.
Abbott’s proposal is modeled off of multiple other state-based programs to fund property-level mitigation and fortification, though the $400 million in funding would be one of the highest funding levels among similar programs. While Abbott’s announcement included few details, a leading program will need to both secure stable, long-term funding sources from the insurance industry, which benefits from these risk-reduction programs, and should require insurers to incorporate resilience upgrades with premium discounts.
5. Oil Prices Back Up
Global energy shortages caused by the Trump-Iran War highlight the need for clean energy sovereignty.
More than a month after originally announcing a ceasefire and with significant flip-flopping, an intensification in the Trump-Iran War over the last few weeks have sent oil prices significantly higher. New blockade threats around the Red Sea from the Iran-backed Houthi Rebels are fueling more concerns that yet another critical chokepoint for global commodities and energy will be blocked, as oil tankers make sudden u-turns.
Shocks to global oil markets have partially been dulled by China reducing crude oil imports enabled by rapid electrification and the United States ramping up exports. But this, in part, comes at the expense of Americans, who are now paying higher prices thanks to higher US exports. Disruptions in the gas markets will significantly raise prices as winter comes and more gas is prepared for export.
These shocks, however, aren’t inevitable, and can be offset by shifting more and more of our energy production towards clean and renewable technologies, which don’t rely on the export or import of volatile fuels. California, for example, recently announced an EV rebate program, to support wider adoption. Such policies help individuals, and the whole country, reduce their dependence and sensitivity to these types of geopolitical risks.
Rocky Mountain Institute Founder Amory Lovins in Brittle Power (1982): “A key feature which helps to make these energy sources resilient is that they are renewable: they harness the energy of sun, wind, water, or farm and forestry wastes, rather than that of depletable fuels.”
HIGHLIGHT: No Secrecy for Insurers
After initially exempting insurers from complying with February 2026 draft regulations implementing California’s climate and emissions disclosure law (SB 253), the California Air Resources Board said in a presentation on Tuesday that it will draft regulations requiring insurers to comply with the law.
CARB had initially declined to include insurers in draft regulations of the state’s new emissions disclosure scheme, arguing that insurers already had to comply with a different set of requirements created by the California Department of Insurance. Now, CARB says it will work with CDI to make sure insurers are complying with the minimum standards set forth in SB 253.
The update is a sign of progress and a reminder that despite the Trump Administration’s best efforts, disclosure continues to move forward, daylighting critical information for markets and investors.
