Renewables exceed coal power in US

Just 10 years ago, the experts were saying that renewables were such a pitiful percentage of our electricity production that even exponential growth in wind and solar would barely move the needle. Well, guess what. Renewables just produced more than coal fired power plants, according to the Federal Energy Regulatory Commission (FERC).

Renewable energy -- including not just solar and wind but also water, biomass and geothermal steam -- narrowly overtook coal by climbing to 257.53 gigawatts of installed capacity, FERC said.
