Been there, done that . . .
An equally pernicious scandal has been running since 2002 - The Renewables Obligation, meant to encourage "clean, green" electricity generation. Set to cost consumers £1,000 million per year until 2025 (with government planning to extend it to 2035), it too is an artificial market.
The scheme is meant to enable Britain to "play its part" in "saving the planet" but there are no mechanisms for measuring whether emissions are actually being cut. No one really cares.
Advsors on the scheme were seconded to the (then) DTI by the wind-power industry, initally for two years but eventually for six, leaving only on retirement and with a gong.
Meanwhile, the same industry is paying members of Greenpeace and similar groups to discredit those who object in any way to wind-power construction projects. It makes the pharmcos look honest.
