Bloomberg, one of the world’s richest men, is also a philanthropist—and Wednesday, he gave an additional $30 million to the Sierra Club’s Beyond Coal campaign. The Beyond Coal campaign is a targeted activism organization that uses public pressure and environmental litigation to force coal plants to close across the country.

The Beyond Coal campaign is widely considered one of the most successful environmental activist pushes of the post–Cold War period. In the past decade, it has closed or secured the retirement of nearly half of the country’s 523 coal plants. Eleven of those plants have announced plans to shutter since President Donald Trump’s inauguration.

“Coal’s share of the energy mix is at a record low,” said Michael Brune, the executive director of the Sierra Club, at the press conference. “In fact, coal plants are retiring at the exact same rate under President Trump as they were under President Obama.”

Bloomberg’s funding will keep the Beyond Coal campaign running until 2020. He also announced $34 million to support the League of Conservation Voters and job-retraining and economic-development programs in Appalachia.

“The war on coal has never been led by Washington,” said Bloomberg. “It has been led by market forces that are providing cleaner and cheaper sources of energy, and by communities, cities, and states that want to protect public health.”

The second of the men is Secretary of Energy Rick Perry. In a fractious age, in a polarized country, Perry has pulled off a rare feat: He has proposed an emergency policy that just about everyone hates—except, that is, for the coal and nuclear industry.

On Thursday, Perry sat before the House Energy and Commerce Committee and defended his “grid reliability” plan, which his department is trying to hustle through the Federal Energy Regulatory Commission, or FERC, in the next 60 days. FERC creates the rules that govern some of the nation’s power grid.

Perry’s proposed rule would pay coal and nuclear plants to remain on the electrical grid in the name of resilience, financially rewarding them for keeping three-month supplies of fuel on premises.

Experts say it would virtually assure that coal and nuclear plants—nearly all of which have been squeezed by the availability of cheaper natural gas and solar and wind power—remain profitable. It could also create a brief boom in the coal market, as plants snap up three months of fuel.

To build support for the rule, Perry has cited the polar vortex of 2014, when frigid weather descended across much of the continental United States. Though the power grid stayed intact through that episode, the largest grid operators saw roughly 20 percent of their power plants shut down. Natural gas plants, in particular, suffered in the weather, but some coal stacks froze as well.
