But how to generate the electricity by renewable means? Nuclear isn't renewable (but could be used in the mid-term), despite obvious dangers. Coal isn't renewable. It has an EROEI ratio much lower than oil, is extremely heavy and therefore harder to transport, and the CO2 emissions will wreak havoc in terms of global warming (unless we can devise a way to utilize coal cleanly, shaving even more off the EROEI). Clean or not, we'll have no choice but to revert to coal when the lights/heat go out. Natural gas isn't renewable and will be entering rapid decline over the next few decades. Solar has had some recent improvements, but we simply don't have enough time/resources/land area to scale it to a degree that could even come close to closing the shortfall from hydrocarbon depletion. Giant wind farms seem to be our best bet, but we still run into the same scalability/time/energy problems. We need some serious imagination and a hell of a lot of courage. Jesse
