According to a report by Greenpeace and the Global Wind Energy Council, Wind has the potential to supply one third of the world’s electricity by 2050.
Ambitious or unrealistic?
Despite 9 years of government support and subsidy, wind farms in the UK, one of the windiest locations in the world, have been erected at a snail’s pace.
Roughly just 1.4 percent of total UK electricity supply comes from wind power. Though the government wants 20 per cent of electricity generation to come from renewable sources by 2020 (most of that capacity provided by wind farms), there are many hurdles.
Primarily, the problem is inadequacy of the electricity infrastructure. The second problem is nimbysism, that is though most people say they approve of wind farms, the average time it takes to get a wind farm through planning is 5 years!
Offshore wind farms were supposed to be the solution. But development has barely begun because of problems with shipping lanes, bird life, radar interference and soaring costs.
Tax breaks in the US and Germany for investors in wind farms have caused a run on turbines, and the soaring cost of steel, required to embed giant turbines 20 meters in the sea bed, make off-shore wind farms look distinctly uncompetitive.
Greater incentives to build offshore can be offset only by higher electricity prices in the long run.
All in all, wind seems good in theory, but plain old blustery in practice.
