January 20, 2026 (Boston, MA) – Conservation Law Foundation (CLF) and other environmental groups have filed a friend of the court brief in support of a coalition of renewable energy industry groups challenging a series of actions taken by the Trump Administration to prevent federal permitting for wind and solar energy projects.
“Federal agencies should be clearing the way for affordable, homegrown clean energy, not putting up unlawful roadblocks,” said Nick Krakoff, senior attorney at CLF. “Wind and solar are among the fastest and most affordable ways to add new power to the grid, yet federal agencies are pursuing an unlawful strategy that stalls projects, raises energy costs, and locks communities into more pollution and climate-damaging emissions.”
The lawsuit in Renew Northeast et al v. United States Department of the Interior et al was filed in December by eight renewable energy groups and is challenging six actions by the Trump administration that unlawfully punish wind and solar development while elevating the fossil fuel industry. In January, environmental groups—CLF, NRDC (Natural Resources Defense Council), Citizens Campaign for the Environment, Environmental Defense Fund, Environmental League of Massachusetts, Environmental Protection Information Center, National Wildlife Federation, New York League of Conservation Voters, and Earthjustice on behalf of Sierra Club—filed a friend of the court brief supporting the renewable energy industry groups’ request for a preliminary injunction.
“These illegal actions undermine fair markets, ratepayer affordability, and state and local efforts to meet state climate and energy mandates,” the groups say in their brief. The actions will increase “reliance on fossil fuels—an outcome that carries well-documented risks to public health, wildlife, and the environment.”
The environmental groups’ amicus brief focuses on the Department of the Interior’s Secretarial Order 3438, the Army Corps of Engineers’ new “capacity density” restrictions, and the Fish & Wildlife Service’s Eagle Take Permit ban. All are unlawful and unsupported by adequate reasoning, the brief says.
“Although wind and solar are variable resources, they are critical to meeting grid reliability needs,” the brief says. “Particularly because wind and solar energy are inexhaustible and geographically diverse, they have delivered more reliable electricity to Americans during extreme weather events, when fossil fuel sources—which are dependent on limited resources and vulnerable to supply chain interruptions—experienced higher levels of outages.”
Currently, wind and solar account for 17% of U.S. electricity generation, with costs dropping dramatically in recent years.
The lawsuit is in U.S. District Court for the District of Massachusetts.
