Wind and Solar diurnal and seasonal variations require energy storage

Posted on June 4, 2015 by

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 →

CSP with thermal energy storage is seasonal, so it can not balance variable power or contribute much power for half the year

Posted on March 9, 2015 by

Concentrated Solar Power not only needs lots of sunshine, but no humidity, clouds, dust, smog or or anything else that can scatter the sun’s rays.  Above 35 degrees latitude north or south, the sun’s rays have to pass through too … Continue reading →
