  • Coal Power Impacts Union Of Concerned Scientists

    coal impacts: water pollution. when you burn charcoal in your grill at home, ash is leftover. the same is true for coal-fired power plants, which produce more than 100 million tons of coal ash every year. more than half of that waste ends up in ponds, lakes, landfills, and other sites where, over time, it can contaminate waterways and drinking water supplies.u.s. coal-fired capacity peaked at 318 gigawatts in 2011 and has been declining since then because many plants retired or switched to other fuels and few new coal-fired plants came online. By the end of 2019, u.s. coal-generating capacity totaled 229 gw. the coal fleets rate of operation, or utilization, has also decreased.
