Gordon Hughes has authored a submission to the House of Commons Energy and Climate Change Committee on behalf of GWPF. The subject is wind power. It makes for horrifying reading.
Meeting the UK Government’s target for renewable generation in 2020 will require total wind capacity of 36 GW backed up by 21 GW of open cycle gas plants plus large complementary investments in transmission capacity. Allowing for the shorter life of wind turbines, the investment outlay for this Wind scenario will be about £124 bilion. The same electricity demand could be met from 21.5 GW of combined cycle gas plants with a capital cost of £13 billion.
Or what about this?
Under the most favourable assumptions for wind power, the Wind scenario will reduce emissions of CO2 relative to the Gas scenario by 21 million metric tons in 2020 - 2.6% of the 1990 baseline at an average cost of about £415 per metric ton at 2009 prices. The average cost is far higher than the average price under the EU’s Emissions Trading Scheme or the floor carbon prices that have been proposed by the Department of Energy and Climate Change. If this is typical of the cost of reducing carbon emissions to meet the UK’s 2020 target, then the total cost of meeting the target would be £120 billion in 2020, or about 6.8% of GDP.
I don't think that anyone expects the committee to even bat an eyelid, let alone pay any attention.
