THE WHITE HOUSE (AP) -- Cutting greenhouse cases. On Monday, the Obama administration will roll out a plan to reduce earth- warming pollution from power plants by 30 percent by the year 2030.
But the plan carries significant political and legal risks, by further reducing the use of coal in producing U.S. electricity.
The president's plan sidesteps Congress, and will go into effect in June 2016, following a one-year comment period.
States will then be responsible for executing the rule with some flexibility.
Coal now supplies just under 40 percent of the nation's electricity.
