PJM, the regional transmission organization (RTO) responsible for grid operations in all or part of 13 Eastern U.S. states and Washington, DC, just asked the federal Department of Energy (DOE) to issue an emergency order under the Federal Power Act. In its request, PJM asked to allow for “large loads” (functionally, although not limited to, data centers located in the PJM footprint) to run emergency backup power generation between July 1 and July 2. This is in preparation for the extreme multi-day heatwave that is forecast for the eastern part of the country through the July 4 holiday weekend.

Across the country, legislators are figuring out how to regulate the worst harms from data centers. In North Carolina, the latest bill to do so is Senate Bill 730. Unfortunately, SB 730 is not a step forward in protecting North Carolinians from the harms of data centers. Rather, it is a step sideways, evading needed regulations.

The Trump administration recently repealed the U.S. Environmental Protection Agency’s 2009 endangerment finding—the scientific and legal determination that greenhouse gases threaten public health and welfare that has anchored federal climate regulation for nearly two decades. Environmental Protection Agency Administrator Lee Zeldin called the finding “the Holy Grail of federal regulatory overreach.” Within weeks, a coalition of more than 20 states filed suit in the U.S. Court of Appeals for the D.C. Circuit to reverse the repeal. The legal battle that follows will help define American environmental policy for a generation. Brigham Daniels and I did not plan the timing of our new book, Lessons for a Warming Planet: A Vital History of US Environmental Law, to coincide with this particular legal conflict. But we could not have chosen a more clarifying moment for its release. The endangerment finding repeal is not an aberration—it is a recognizable recurrence in a history that stretches back centuries. Law has always been the primary engine of both environmental exploitation and protection in the United States.

On April 23, the Baltimore Sun published an op-ed lambasting efforts by localities and states to hold the fossil fuel industry responsible for decades of misinformation about the dangers of their products. These hazards to the public’s health, welfare, and safety are now coming home to roost in the form of extreme weather, increased flooding […]

On April 24, The Washington Postpublished an op-ed that sought to blame an unusual source for the high energy and gas prices Americans are now facing: justice. Specifically, it claims that these price increases are the result of state and local governments trying to hold Big Oil accountable for the climate-related harms their constituents are continuing to suffer. I submitted a letter to the editor debunking the op-ed’s argument, noting that the real cause of higher gas prices is the illegal war in Iran.

As the release date of my forthcoming book, Unlearn Power: Strengthening Communities in the Age of Environmental Crisis, approaches, naturally, I've been asked, "What's the book about?" But given the amalgamation of ecological devastation across the planet, with fallout and stakes unevenly felt across socioeconomic lines and underscored by political forces that engage in climate denialism and assaults on democratic institutions, I urge that "Why Unlearn Power?" is the more apropos question.

Maryland’s 2026 legislative session represented a challenging playing field for advancing climate and environmental legislation, marked heavily by the dual considerations of budget shortfalls — driven by the federal government’s abandonment of funding critical programs and sowing chaos among the numerous federal workers who live in Maryland — and uncertainty as to long-term energy reliability and affordability placing a pall on energy planning in the state.

In early April, The Washington Post published an op-ed trashing state and local efforts to hold Big Oil and Gas accountable under the law for the lies they told about their products’ connections to climate change and damages they inflict on people and the planet. I submitted a letter to the editor presenting counterpoints to the op-ed’s claims, which included the absurd notion that insulating some of the biggest companies on earth from even a small measure of justice is somehow a vital “national security” interest. The Post chose not to run that letter, so I’m sharing it with readers here.

In 2025, North Carolina saw an effective repeal of its carbon plan, and the state is now on track to approve over 100 data center projects. This will further imperil the state’s 2050 decarbonization goal while creating a new slew of environmental and public health concerns and electricity affordability problems. The state is charting a harmful path and should change course before its policies hurt more people and communities.
