Energy Net on 21 Feb 09Most climate experts accept that, in order to avoid catastrophic effects of global warming, greenhouse gas emissions (mostly CO2) must be cut by 60-80% by 2050 (though the figure may need to be a 95% cut in the US). The belief that replacing fossil fuels with solar and wind technology can accomplish this reduction tends to overlook several factors: 1. Corporations bombard the world with the message that everyone should consume like Americans do; 2. Corporations tell those in the US that they should ape after the playthings of the rich; 3. Population is growing; 4. Market economics force pathological expansion; and, 5. Solar and wind comprise a minute fraction of current energy. Let's combine these to get an idea of how much solar and wind would need to expand to replace coal, oil, nukes and gas by 2050. First, the US consumes about 25% of the world's energy while having only 5% of the world's population. For the rest of the world to consume at the rate of the US would require global production to increase by a factor of 6.33.
