Yes, absolutely, as a general point, I would agree with you, and I think you made a very pertinent point around this during a debate last week. You can't just keep using fossil fuels, as you say, when you're looking at hydrogen, for instance, and electric vehicles. Obviously, I'm concerned about the national grid capacity anyway. I've had some very concerning discussions with National Grid in relation to this, so, yes, certainly as a general point I would agree with you.
