Non renewable energy sources
It would be easier to answer what are RENEWABLE energy sources. These would be always available like the sun, wind, water flowing in streams and the ocean waves. It also includes bio-available energy like alcohol and bio-diesel oil. We may one day have to use our post-consumer waste as an energy source – that seems to be endlessly renewable.
The non-renewable sources were created eons ago and not likely to have any new sources once we have tapped what we can find. We may create new technologies to find and extract more, but the earth is not creating it as fast as we are consuming it. Coal, oil, natural gas.
