The Myth Of Alternative Energy
by Peter Goodchild
September 24, 2006
Alternative sources of energy will never be very useful, for several reasons, but mainly because of a problem of "net energy": the amount of energy output is not sufficiently greater than the amount of energy input. Alternative sources simply don't have enough "bang" to replace 30 billion annual barrels of oil.
A further problem with alternative sources of energy is that conventional oil is required to extract, process, and transport almost any other form of energy; a coal mine is not operated by coal-powered equipment. It takes "oil energy" to make "alternative energy."
***
More-exotic forms of alternative energy are plagued with even greater problems. Fuel cells cannot be made practical, because such devices require hydrogen derived from fossil fuels (coal or natural gas), if we exclude designs that will never escape the realm of science fiction; if fuel cells ever became popular, the fossil fuels they require would then be consumed even faster than they are now. Biomass energy (perhaps from wood, animal dung, peat, corn, or switchgrass) would require impossibly large amounts of land and would still result in insufficient quantities of net energy, perhaps even negative quantities. Hydroelectric dams are reaching their practical limits. Solar, wind, and geothermal power are only effective in certain areas and for certain purposes; such types of power, in any case, are only of significant value when converted into electrical energy, requiring the use of disposable batteries - a practice as ecologically unsound as the use of fossil fuels. Nuclear power will soon be suffering from a lack of fuel and is already creating serious environmental dangers.
Petroleum, unfortunately, is the perfect fuel, and nothing else even comes close. There will never be a solar-powered airplane. The problem with flying pigs (as in "when pigs can fly") is not that we have to wait for scientists to perfect the technology; the problem is that the pig idea is not a good one in the first place. To maintain an industrial civilization, it's either oil or nothing.
***
The quest for alternative sources of energy is not merely illusory; it is actually harmful. By daydreaming of a noiseless and odorless utopia of windmills and solar panels, we are reducing the effectiveness of whatever serious information is now being published. When news articles claim that there are simple painless solutions to the oil crisis, the reader's response is not awareness but drowsiness. We are rapidly heading toward what has been described as the greatest disaster in history, but we are indulging in escapist fantasies. All talk of alternative energy is just a way of evading the real issue: that the Industrial Age is over.
