There is one other issue that applies to Solar and Wind power generation and that is the issue of UP TIME. Since most modern coal, oil, water and nuclear plants have UP TIMES around 90% and solar and wind are 1/3 of that, that means that their effective power ratings should be reduced by 2/3’s so we can compare apples and apples. This is not an insignificant fact and it has serious ramifications when use is high like in the winter when its cold and in the summer when its hot. Last winter the grid came very close to dropping out — with less available power we will be more vulnerable to brownouts this winter!
