I tried to start a company to make wind turbines in the '980s and was told it would never work. Now the Government wants to use millions of them all over the country.
As for microgeneration, unless you have a wind turbine with a 6 meter diameter rotor you are waisting your time. Likewise with solar cells you would need at least 40 sq m area to generate any useful power, i.e. something that has a pay back period in years not decades.
I also think the estimated rise in power bills is off by at least an order of magnitude.
Unless nuclear power stations are built fast there will be power shortages in the UK by 2020 if not before, all the green energy supplies not withstanding.
I know the green lobby would love the country to revert to the dark ages but to do that would require the population to be reduced to that level as well, maybe the greens should be the ones to volunteer to drop dead first then those remaining can get on with their lives in peace.
