I think we could eliminate coal, nuclear and natural gas power plants if we just went back to lighting our homes with lamps that burn Sperm Whale Oil! Unlike candles kerosene lamps, whale oil burns clean and smokeless. The Japanese still have a whaling fleet so we could just have them supply us.
Ok, I'm being very sarcastic, I would much rather burn dead dinosaurs than kill whales to light my home. (Even if I believe in abiotic oil:
The 'Abiotic Oil' Controversy).
