The daily telegraph today [17/10/08] say that Ed Milliband is "Bold and Courageous" in his announcement about reducing CO2 emissions by 80% by 2050.  Why ? from The Doomsday Book until about the middle of the last century Renewable Engineering and Energy was a source of power and wealth.  Not only can it counter Climate Change, but also assist National Wealth creation, counter Inflation, Fuel Poverty and adverse Balance of Payments. Properly set on locally, with communities once more in control of their local energy collection/generation [might eliminate Council Tax ?] there are vast potential benefits. The above points have been made to Lord Adair Turner, and senior Civil Servants. Anyone agreeing to the above is asked to write to his/her MP along the same lines please. see also this from the USA
