    1. In basic English, “it takes two coal workers, 169 solar workers and 1,100 wind workers to equal the work of one natural gas worker.”

      One has to compare all the factors. Fossil fuels are dense but are nonrenewable. Once installed, renewables continue generating as long as the infrastructure is intact. Extending the lifetime of the infrastructure increases the cost competitiveness further. What is the net energy produced by low energy density renewables over its lifetime and how does it then compare with high density fossil fuels?
