EROEI of fossil fuels is pretty pathetic. It has been going down over time for the last 100 years. It won't take more than 30 years until oil hits an EROEI of 1. If you had followed any of the trends of renewable technology then you should be aware that economic collapse and deindustrialization are easily avoidable. Maybe there will be 10 days in a year that the most energy intensive factories will have to shut down due to a combination of low wind and solar but this also means on 10 other days in the year there will be an excess of energy.
