It’s all in how you spin it. Supra-zoogle-watts of new wind power capacity was added last year. Wind and solar grew faster than fossil fuels. There are now 341,000 wind turbines around the world! Thus do Meaningless Big-Numbers flow.
Instead Matt Ridley gets down to the small numbers that tell us what is going on: Wind Turbines are neither clean nor green.
The Spectator: Here’s a quiz; no conferring. To the nearest whole number, what percentage of the world’s energy consumption was supplied by wind power in 2014, the last year for which there are reliable figures? Was it 20 per cent, 10 per cent or 5 per cent? None of the above: it was 0 per cent. That is to say, to the nearest whole number, there is still no wind power on Earth.
Key Renewable Trends IEA 2016
The only renewables superstars are those you never hear about — wood and hydro:
Their trick is to hide behind the statement that close to 14 per cent of the world’s energy is renewable, with the implication that this is wind and solar. In fact the vast majority — three quarters — is biomass (mainly wood), and a very large part of that is ‘traditional biomass’; sticks and logs and dung burned by the poor in their homes to cook with. Those people need that energy, but they pay a big price in health problems caused by smoke inhalation.
…world energy demand has been growing at about 2 per cent a year for nearly 40 years.
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.
So we’d have to build 350,000 wind turbines every year just to keep up with the growth in electricity demand each year.
To be fair, apparently wind power generates nearly 5% of Australia’s total energy, which is at the same time, pretty remarkable, and also maybe why manufacturing here is dying.
Here’s a meanginless small number:
Portugal ran for four days straight once on renewable energy alone. Four whole days!
