I will give way in a moment. Let me just finish the argument.
The renewables obligation is an obligation because the energy is more expensive. Indeed, the Department of Energy and Climate Change’s own estimation is that, by 2020, the cost of paying for expensive renewable energy, more and more of which is coming on to the grid, will be about £190 per household. At the same time, we in this House complain about fuel poverty, when one of the contributors to fuel poverty is the fact that we are orientating ourselves towards more expensive electricity generation. Only last week there were complaints about Tata Steel closing down its plant.
