Dumb Energy The Fake Promise of Wind and Solar Electricity DumbEnergy.com
Exposing the dumb energy world - Wind and Solar "Renewable Energy" It's dumb because it costs too much. It's heavily subsidized by the taxpayers and utility customers. Furthermore, there are much more cost-effective ways of preventing global warming. (If you still believe in that.)
Wind and solar are erratic sources of electricity. Solar stops when a cloud passes in front of the sun or the sun sets. Wind fades when the wind is weak. Thus wind or solar must be backed up by other generating plants, most commonly natural gas generating plants. The backup plants must ramp up and down to compensate for the ups and downs of the erratic wind or solar power. Typically, wind and solar do not replace existing generating plants and are not a substitute for adding traditional generation when demand increases. They are erratic and can't be counted on. The consequence is that the only economic contribution of wind or solar is to reduce fuel consumption in the backup plants when the wind or solar is actually generating electricity. To generate a kilowatt hour of electricity with wind or solar costs about 7-cents. That kilowatt hour saves about 2-cents worth of fuel in the backup plants. The consequence is that 7-cents minus 2 cents represents 5-cents wasted for each kilowatt hour of electricity produced. The 5-cents per kilowatt hour is the subsidy for wind or solar. The subsidy comes from explicit government subsidies, tax loopholes subsidizing investors, and power purchase agreements that provide overly-generous payment for renewable electricity.
