Solar, wind, hydro, and geothermal are widely considered benign energy sources. For the most part, they are. They harness nature without producing noxious emissions or significant waste streams. They don’t require strip mining, punching a hole in the seabed, fracturing bedrock, or splitting atoms. From sailboats to south-facing gardens, hot springs to millstreams, green energy’s friendly reputation predates hydrocarbon and fission by centuries.
