[ China and Nuclear Power ] [A modern solar plant in Portugal] occupies about 0.234 square miles of land, and is expected to produce about 20 gigawatt-hours per year. That works out to an average power output of about 2.28 megawatts. How much land would we have to cover with these panels to get 200 gigawatts?...200,000 / 2.28 x 0.234 = 20,526 square miles.That's like covering all of Massachusetts 2.5 times over.
[ Solar powered reality ] [After a comment from me quoting Steven Den Beste on the land requirements to supply enough power to replace California's gas usage--which Den Beste pegged at 525 square miles ]Now today on Watts Up With That they point out that all of that land has property taxes levied on it:
According to the CIA, the USA has 4,165,110 km of paved roadway. Let's assume that the average width of a roadway is 50 feet, just a guess. Suppose that instead of paving all those streets, roads, highways and expressways we paved a big square in the middle of the desert. How big on a side would that square be?
sqrt(4165110 * 5/8*5280*50)/5280 = 157.0078
That square would only be 157 miles on a side. Think how much effort it took to pave that much. Think about how much effort it would be to cover that area with solar panels.
Producing 225,592 kilowatt hours of electricity in its first year of operation, a solar farm in eastern Kalamazoo County that went online in early 2010 has exceeded expectations.Also:
Also exceeding expectations is the property tax, said Sam Field, a Kalamazoo attorney and one of the owners of Kalamazoo Solar.
The $27,689 tax bill for the Charleston Township property means that the owners are losing money, even when being paid a premium price of 45 cents a kilowatt hour by Consumers Energy, he said.
“That Michigan property tax burden works out to a cost of 12.3 cents per kilowatt hour,” Field said. “That amount is more than the retail value of the electricity.”For comparison, Field researched the property tax for the Palisades Nuclear Plant in Covert Township along Lake Michigan. He found that the annual real and personal property taxes for Palisades are just over $12 million or .2 cents per kilowatt hour.
