Energy efficiency?

I thought I won the jackpot when my EuroMillions ticket came up, but renewable energy is the real deal. The Estate is now self-sufficient in electricity, and the good thing is, the government will pay a £25 subsidy on top of every £15-worth of electricity supplied to the national grid. And the subsidies keep on coming whether or not the wind blows; and also if it blows so strongly that the turbines have to be switched off. Welcome to the future!
