California, Colorado, and Washington led 10 other states in suing the Trump administration this week over the Department of Energy’s termination of billions in federal funding for clean energy and infrastructure projects. In a lawsuit filed in federal court in San Francisco, the states accuse the agency of using a “nebulous and opaque” review process to justify slashing billions in funding that was already awarded. “These aren’t optional programs — these are investments approved by bipartisan majorities in Congress,” California Attorney General Rob Bonta said at a press conference announcing the lawsuit, according to Courthouse News Service. “The president doesn’t get to cancel them simply because he disagrees with them. California won’t allow President Trump and his administration to play politics with our economy, our energy grid and our jobs.”

An infographic highlighting how different geothermal technologies work.EIA
If you’re looking for a sign of the coming geothermal energy boom in the U.S., consider this: There is now a double-digit number of next-generation projects underway, according to an overview the Energy Information Administration published Thursday. For the past century, geothermal energy has relied upon finding and tapping into suitably hot underground reservoirs of water. But a new generation of “enhanced” geothermal companies is using modern drilling techniques to harness heat from dry rocks.

If you’re looking for a thorough overview of the technology, Heatmap’s Matthew Zeitlin wrote the definitive 101 explainer here. But a few represent some of the earliest experiments in enhanced geothermal, including the Fenton Hill in New Mexico, established in the 1970s, which was the world’s first successful project to use the technology.

When Exxon Mobil announced plans in December to scale back its spending on low-carbon investments, the oil giant justified the move in part on all the carbon capture and storage projects poised to come online this year that would vault the company ahead of its rivals. This week, Exxon Mobil started transporting and storing captured carbon dioxide at its latest facility in Louisiana. The New Generation Gas Gathering facility on the western edge of the state’s Gulf Coast is the company’s second CCS project in Louisiana. Known as NG3, the project is set to remove 1.2 million tons of CO2 per year from gas streams headed to export markets on the coast. The Carbon Herald reported that two additional CCS projects are set to start up operations this year.
CCS got a big boost in October when Google agreed to back construction of a gas-fired power plant built with carbon capture tech from the ground up. The plant, which Matthew noted at the time would be the first of its kind at a commercial scale, is sited near a well where captured carbon can be injected. Senate Democrats, meanwhile, are reportedly probing the Trump administration’s decision to redirect CCS funding to coal plants.
In 2019, Maine expanded its Net Energy Billing program to subsidize construction of commercial-scale solar farms across the state. “And it worked,” Maine Public Radio reported last July when the state passed a law to phase out the funding, “too well, some argue.” In 2025 alone, ratepayers in the state were on the hook for $234 million to support the program. Solar companies sued, arguing that the abrupt cut to state support had unfairly deprived them of funding. But this week U.S. District Judge Stacey Neumann denied a motion the owners of dozens of solar farms filed requesting an injunction.
That isn’t to say things aren’t looking sunny for solar in Maine. On the contrary, just yesterday the developer Swift Current Energy secured $248 million in project financing for a 122-megawatt solar farm and the Poland Spring water company went on statewide TV to show off the new panels on its bottling plant. The federal outlook isn’t as bright at the moment. As Heatmap’s Jael Holzman reported in December, the solar industry was begging Congress for help to end the Trump administration’s permitting blockade on new projects on federal lands.
The Trump-stumping country music star John Rich is continuing his crusade against the Tennessee Valley Authority. Months after blocking construction of a gas plant in his neighborhood, Rich personally pressed TVA CEO Don Moul to reroute a transmission line, posting a video Thursday of farmers who opposed the federal utility’s use of the right of way process to push through the project. Rich said Moul “personally told me as of this morning” TVA will put the effort on hold. The left-wing energy writer and Heatmap contributor Fred Stafford summed it up this way on X: “MAGA NIMBY rises, Dark Abundance falls. TVA ratepayers will be paying more for a rerouted transmission project because this country music star threw his support behind a local farmer who refuses to allow the transmission line to cross his land.”
