Energy Returned on energy invested


Much has been written about how intermittent renewables like wind and solar negatively affect grid stability and often need government subsidies to produce positive financial returns on investment (ROI). Less well understood, but even more important, is the fact these intermittent renewables reduce our global net energy surplus when compared to the coal, oil, natural gas and nuclear energy sources they replace. In other words, our current technologies generate a higher energy output on their energy inputs versus wind and solar.
