Meet the super PAC working to crush clean energy's political foes

A new political group is trying to punish lawmakers who voted to roll back clean energy tax credits last year in the One Big Beautiful Bill Act, which ended a decade-old federal tax break meant to speed up solar and wind adoption. The group, called the Invest in Tomorrow Coalition, was started by clean energy investors and former advocacy leaders after Congress gutted those incentives with little political cost to the Republicans who voted for it. The coalition has raised about $20 million to spend on this year's elections, targeting members of the House Freedom Caucus who pushed hardest against clean energy.

So far the group has intervened in five Republican primary races, and its side won every time, including a high-profile loss last week by South Carolina Rep. Ralph Norman, who was running for Senate. The ads mostly did not mention clean energy directly. Instead they questioned candidates' loyalty to Trump or highlighted personal controversies, a strategy the group says it tests carefully before spending money. The group plans to spend up to $30 million this cycle and has now moved into its first Democratic primary, targeting Rhode Island's governor.

None of this changes any rebate, tax credit, or program available to homeowners right now. It is a story about political strategy, not new incentives. But it points to an effort by the clean energy industry to build more influence in Washington, which could shape whether federal support for things like solar, heat pumps, or home electrification expands or shrinks in future elections.
