Wind and Solar diurnal and seasonal variations require energy storage
Preface. Currently energy storage is accomplished with the 67% of fossil fuels (natural gas and coal) used to generate electricity, especially natural gas which can kick in within microseconds to make up for failing wind, or run all the time … Continue reading
