Biden’s next climate rule is already causing a stir. Here are 4 things to know about it.

The Biden administration is expected to plunge Thursday into a transformation of the U.S. power industry — by requiring utilities to either reduce or capture their planet-warming pollution.
The release of the Environmental Protection Agency’s proposed rules for power plants will answer a slate of questions about how it plans to maximize carbon reductions from gas- and coal-fired electricity, the nation’s second-largest source of greenhouse gases.
EPA has tried and failed to do this twice before. Both times, federal courts threw out the rules — rejecting the Obama administration’s attempt to replace fossil fuels with renewable energy, while faulting the Trump administration for doing too little to confront climate change.
