Wind and solar power are expensive, realistically four to six times the cost of conventional energy sources. If we are going to convert to electric cars we will need lots of energy to make the batteries for the cars as well as to charge them. In a separate category, the global warming scare tries to impress upon us the need to avoid fossil fuels immediately for fear we all fry by 2010, or whatever the current date of doom. Underneath these discussions is the question of how much oil is left. When the oil equivalents like oil shale are counted, we have about 300 years.
Peak oil theory is that oil production will not just peter out, it will fall catastrophically starting right now, and that no alternative energy source will arise to take its place. The result will be inevitable disaster, so they say. A book advocating peak oil theory starts by erroneously begins with a false application of the concept of a closed system. It’s worth setting straight.
