What We Know About Trump’s Endangerment Finding Repeal

The administration has yet to publish formal documentation of its decision, leaving several big questions unanswered.

President Trump announced on Thursday that he was repealing the Environmental Protection Agency’s scientific determination that greenhouse gases are dangerous to human health and the natural world.

The signal move would hobble the EPA’s ability to limit heat-trapping pollution from cars, trucks, power plants, and other industrial facilities. It is the most aggressive attack on environmental regulation that the president and his officials have yet attempted.

There’s More Than One Way to Build a Wind Turbine

Startups Airloom Energy and Radia looked at the same set of problems and came up with very different solutions.

You’d be forgiven for assuming that wind energy is a technologically stagnant field. After all, the sleek, three-blade turbine has defined the industry for nearly half a century. But even with over 1,000 gigawatts of wind generating capacity installed worldwide, there’s a group of innovators who still see substantial room for improvement.

The problems are myriad. There are places in the world where the conditions are too windy and too volatile for conventional turbines to handle. Wind farms must be sited near existing transportation networks, accessible to the trucks delivering the massive components, leaving vast areas with fantastic wind resources underdeveloped. Today’s turbines have around 1,500 unique parts, and the infrastructure needed to assemble and stand up a turbine’s multi-hundred-foot tower and blades is expensive— giant cranes don’t come cheap.

1. Alabama weighs scrapping utility commission elections after Democratic win in Georgia

Back in November, Democrats swept to victory in Georgia’s Public Service Commission races, ousting two Republican regulators in what one expert called a sign of a “seismic shift” in the body. Now Alabama is considering legislation that would end all future elections for that state’s utility regulator. A GOP-backed bill introduced in the Alabama House Transportation, Utilities, and Infrastructure Committee would end popular voting for the commissioners and instead authorize the governor, the Alabama House speaker, and the Alabama Senate president pro tempore to appoint members of the panel. The bill, according to AL.com, states that the current regulatory approach “was established over 100 years ago and is not the best model for ensuring that Alabamians are best-served and well-positioned for future challenges,” noting that “there are dozens of regulatory bodies and agencies in Alabama and none of them are elected.”
