Almost two years after a similar rule was rejected by the Supreme Court, the Biden administration on Thursday released another final rule for regulating America’s power plants.

Under the rule, coal-fired power plants and most new natural gas-fired power plants would have to eliminate 90% of their carbon emissions by 2039 or close down in 2040.

The Environmental Protection Agency’s new rule would raise electricity costs for Americans, kill manufacturing jobs, and disproportionately affect the poor, farmers, and small business.

EPA’s rule, if it overcomes legal challenges, would result in the closure of coal-fired power plants that now produce 16% of Americans’ electricity. It would make natural gas power generation, which produces 43% of electricity, more costly and increase the incidence of blackouts.
