I think that would be the case of Ukraine, but it's not the case for us or it's not the case of the European Union. In all those cases, energy is priced at the margin. Certainly that is the problem that Ukraine has today, in that Russia uses economic power through the pricing of natural gas. There is no doubt about that. That is the problem, and that's not going to go away any time soon. There's certainly no simple solution, as you've heard already, that could change it overnight.
As I said, a few weeks ago when we were in Germany, Chancellor Merkel was very adamant that in the last 60 years, Europe has been complacent over its dependence on Russia and that it's something that needs to change.
When you look at renewables as the answer, Germany is a very good market to look at. They use renewables probably more than any developed economy. Without fossil fuels or nuclear to balance out the load, they would have serious difficulties.
I think it's very naive to think that solar and wind are going to power an earth that has six billion people on it. It's just not realistic. Even Germany itself is finding in its experiment with renewables that they're still a long ways from a scenario where fossil fuels will not be part of the solution.
