Intermittent wind, solar, and wave power can not replace fossil fuels and nuclear power electricity generation without energy storage

Hydropower has a very low energy density

Posted on March 17, 2015 by

To store the energy contained in 1 gallon of gasoline requires over 55,000 gallons to be pumped up 726 feet (CCST 2012). As a thought experiment look at what it would take generate all of America’s 4,058 TWh electricity, where … Continue reading →
