Mining of and delivery of the vital materials needed to construct renewable energy infrastructure relies heavily on oil. Renewables also do not come anywhere close to the EROEI that oil provides, and they also fall far behind coal and natural gas. The amount of these non-renewable resources as a percentage of the energy required to run the global economy is so far past renewables that they are essentially a non-starter; we do not have enough to both power the current economy AND retrofit it to use renewables. Essentially, the amount of energy we get from renewables will dramatically slow and then stop once we accelerate down the downslope of Hubbert’s peak for oil, coal, and natural gas.
