The Growth of Solar Capacity In California, Capacity Utilization, and Solar Energy Production.

[John ONeill]

17. Why Nnadir is right

If you look at this site showing, as an example, the electricity production and associated greenhouse gas emissions of Kyushu island in Japan, as determined by the Intergovernmental Panel on Climate Change, you will see that the CO2 emissions per kilowatt hour for solar are about four times higher than for nuclear ( 45 grams/kwh, versus 11 for nuclear.) If you scroll down a bit to the graph showing electricity consumption for the last 24 hours, though, you can see the real strike against solar. Kyushu gets 30 to 40 % of its power from nuclear ALL DAY, while solar has a bell-shaped curve, where it makes up to about 45 % at noon, declining steeply to zero a few hours later. '?' makes the rest, '?' being, of course, gas and coal. A modern society can no more function without 24 hour power than a mammal can live without breathing, and if the power sources promoted by solar fantasists only work 20% of the time, fossil fuels will pretty much everywhere make up the difference. https://www.electricitymap.org/zone/JP-KY?wind=false&solar=false
