You didn’t need to mention them David… Aren’t they “renewables”, as are wind and solar?
My response has been to your statement, that it’s utter nonsense that renewables are not economically viable.
Perhaps you know of other sources of renewables that are currently on a par with the energy from fossil fuels?.. That they “would be” if subsidies were taken away from the Petrol-chemical industry, is wishful thinking, at best! We all must live in the real world.
Of course in the distant future, new energy sources will be very necessary, and I support the research currently in progress. Until there is more that a reasonable chance, that renewables can provide the energy levels necessary, for not only the developed nations, but those not so fortunate, I will stay with fossil fuels.
