Not Clearly Pro or Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"
"[U]nless another source of energy [other than oil], just as cheap, with just as high a ratio of 'energy return on energy invested' (EROEI) is discovered or developed, there will be a gradual decline in our ability to generate the growth required to keep the debt-based financial system from collapsing...
The only question worth asking is what we intend to do about it. There might be a miracle cure. Photosynthetic energy, supercritical geothermal fluid drilling, cold fusion, hydrocatalytic hydrogen energy and various other hopeful monsters could each provide us with almost unlimited cheap energy. But we shouldn’t count on it. The technical, or even theoretical, barriers might prove insuperable. There are plenty of existing alternatives to oil, but none of them is cheap, and none offers a comparable EROEI."
