Sep 06, 2020 The magical science of power plants. A single large power plant can generate enough electricity (about 2 gigawatts, 2,000 megawatts, or 2,000,000,000 watts) to supply a couple of hundred thousand homes, and that's the same amount of power you could make with about 1000 large wind turbines working flat out. But the splendid science behind this amazing trick has less to do with the power plant

Nov 15, 2017 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.
