Coal-fired power plants have caused twice as many premature deaths as previously believed, killing at least 460,000 Americans in the past two decades.
Fine particulate matter (PM2.5) from coal plants is twice as deadly as PM2.5 from other sources, and previous studies underestimated the dangers of coal pollution.
Strong government regulations are necessary to reduce the health risks associated with coal pollution and implement cost-effective solutions like emissions controls and renewables.
