ENERGY SECURITYWill New Interior Department Rules Shackle Wind and Solar? Insiders Are Divided.

Some Republicans felt that the massive budget bill that President Trump signed into law earlier this month did not go far enough in discouraging the growth of wind and solar power. So we know new Interior Department rules will slow wind and solar development — but we don’t yet know how much.

The massive budget bill that President Trump signed into law earlier this month took aim at a robust system of tax credits that have aided the explosion of U.S. wind and solar energy in recent years. While the move was primarily intended to help enable the law’s extension of tax breaks for high-earning Americans, some Republicans felt the law did not go far enough in discouraging the growth of wind and solar power. Those holdouts, however, voted for the bill after saying they’d received assurances from President Trump that he’d use his executive authority to further stymie the energy sources. 

“We believe we’re going to get 90-plus percent of all future projects terminated,” U.S. Representative Chip Roy of Texas told Politico after the bill passed. “And we talked to lawyers in the administration.”

Last week, Trump’s Department of the Interior announced what appeared to be a fulfillment of the president’s promise to his party’s right wing. The department’s new guidelines for wind and solar developers now require all federal approvals for clean energy projects to undergo “elevated review” by Interior Secretary Doug Bergum, who was appointed by President Trump in January.

The new guidelines include a granular outline of steps that will now require personal approval from Bergum’s office, rather than being delegated to department bureaucrats as had previously been customary. Experts who spoke to Grist say that this could create an unmanageable slowdown for developers and allow the administration to quietly kill wind and solar projects on public land. Some are even worried that the effect of the updated regulations will spill over into private projects, which sometimes have to consult with the Interior Department when their work bleeds into federal lands or a habitat for endangered species.

Since only 4 percent of existing renewable energy projects are on public land, clean industry insiders who have interpreted the new policy narrowly are not yet panicking. But those with a broader interpretation of the text — or those who suspect that the administration will take a broad interpretation — wonder if the new rules will amount to a de facto gag order on the industry. For now, only time will tell just how many of their fears come to pass.
