Wind turbines are neither clean nor green and they provide zero global energy–Matt Ridley | NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood   h/t HotScot & Coeur de Lion   For those who have not seen it, here is Matt Ridley’s piece in the Spectator last week:   The Global Wind Energy Council recently…

…………………….

Even in rich countries playing with subsidised wind and solar, a huge slug of their renewable energy comes from wood and hydro, the reliable renewables. Meanwhile, world energy demand has been growing at about 2 per cent a year for nearly 40 years. Between 2013 and 2014, again using International Energy Agency data, it grew by 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? The answer is nearly 350,000, since a two-megawatt 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 into this so-called industry in the early 2000s.

At a density of, very roughly, 50 acres per megawatt, typical for wind farms, that many turbines would require a land area [half the size of] 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 [half] the size of Russia with wind farms. Remember, this would be just to fulfil the new demand for energy, not to displace the vast existing supply of energy from fossil fuels, which currently supply 80 per cent of global energy needs.
