is that having your cake and eating it and do you think those sums add up? they kind of do add up. the long—term costs, speaking like an economist, the long—term costs are lower than gas. once you build the things, as soon as the wind blows, you get energy. so they can be a lot cheaper, certainly at the moment. the problem is the way the uk market works, the price for electricity for consumers is set by the gas price, so it's very high. what they're looking at doing is decoupling electricity prices from gas, benefiting from the lower long—term costs of renewables, and they hope that way they can lower energy prices. lots of people who work in the sector would say that probably will work. it's certainly something they will explore. in this report, they say they have an ambition to explore the potential to do that. that's something they hope to do in the next couple of years.
