Issues With Wind Farms

Issues With Wind FarmsThe International Energy Agency released data that revealed the percentage of total global primary energy demand provided by wind and solar is 1.1 percent. 1 Hardly the kind of number derived from wind and solar lobbies.
Another report confirms what should have been obvious from the start: the more ‘variable’ wind and solar are introduced into any electricity system, the more they make it both more expensive and less reliable.

World energy demand has been growing at about 2 percent a year for nearly 40 years. Between 2013 and 2014, using International Energy Agency data, it grew just under 2,000 terawatt-hours. If wind turbines were to supply all of that growth but no more, how many would need to be built each year asks Matt Ridley. The answer is nearly 350,000, since a two-megwatt turbine can produce about 0.005 terawatt-hours per annum. That’s one-and-a-half times as many as have been built in the world since governments started pouring consumer funds in this industry in the early 2000s. Ridley adds, “At a density of, very roughly, 50 acres per megawatt, typical for wind farms, that many turbines would require a land area greater than the British Isles, including Ireland, every year. If we kept this up for 50 years, we would have covered every square mile of a land area the size of Russia with wind farms. Remember, this would be just to fulfill the new demand for energy, not to displace the vast existing supply of energy from fossil fuels, which currently supply 80 percent of global energy needs.†2
