Dear Luber,
You seem smart. I have a question. I believe that solar power or wind power systems cannot produce enough energy in their lifetimes to reproduce themselves. That is, wind or solar plants could not provide enough energy to mine and transport the Al, pump and refine the oil; smelt the iron, copper, silicon, etc. Assemble and transport the components (tower, blades, motors. etc.) to repay the energy debt they have made in their construction. I believe that nuclear hydrocarbon (mostly coal) and hydro electric systems would have to provide all this energy to build the wind or solar systems. A negative energy deficit. I cannot find any data on the web regarding this. Do you have any direction for me?

Thanks,

Mike Dempsey
