Wind, water, biomass, and the sun are the oldest energy sources used by mankind. The inherent limitations of these sources motivated people to seek more efficient and reliable fuels to power society.
The peak use of windmills was in the 1930s and 1940s. Farmers stopped using them because rural electrification provided electric power far more reliable and often less expensive than wind. Yet today, we are turning back to this expensive and inefficient energy source because of government mandates and subsidies, which are driving up electricity costs for Texas consumers.
