According to data published by the United States Energy Information Agency, in April, 2019, for the first time ever, the renewable energy sector (hydro, biomass, wind, solar and geothermal) generated more electricity than coal-fired plants.
This news is not quite so gloomy for the coal industry as it appears. There are seasonal considerations. Of particular note, is the long-held practice of taking coal plants offline during the lower demand periods of the spring (and fall) to perform maintenance and upgrades to ensure that they are ready for the higher demand of the summer and winter seasons. In addition, spring tends to be peak time for hydro generation.
While this particular instance of coal being out produced by renewables is partly due to seasonal considerations, the long term trend lines reported by the Energy Information Agency show coal decreasing while renewables increase.
