>Solar and wind is a loosing proposition (you put more hydrocarbons into making them than they will generate in their lifetime, and you don't get to pick when they generate), and it can't carry the losses of hydrocarbons. See here: https://skeptics.stackexchange.com/questions/17775/how-long-... >TLDR; Onshore wind produces around 20-80 times as much energy as is required to produce the turbines. Offshore wind about 10-20 times. PV around 10-20 times. The top answer is 10 years old, there's 10 years of manufacturing and output efficiencies to further improve these ratios. |
