Yes, although I don't think that that is entirely true in that, you know, certainly some of the alternative forms of energy have become cheaper.

Like what?

Well, the renewable forms of energy have become cheaper.

So wind, solar... Wind and solar.

They're cheaper than burning?

Yes.

Really?

However...

However, the flip side of that is that they are intermittent forms.

So you need to either be able to store the energy that they create, or you need to find a way to fill in when they're not produced.

If you are taking all of the pros of all of the different energy sources and all of the cons of different energy sources and you factor in the impact of the use of fossil fuels into that equation, then it drives you necessarily to forcing the pace on some of the alternatives.

Now, some of the alternatives are perfectly workable

and will become better, we know, if we drive them.

So nuclear technology, for instance, stood still for 20, 30 years because we got scared about it after Chernobyl and we froze the development of that technology where it was.

The existing nuclear power stations are using 30-year-old technology, basically.

That's reassuring.

Fourth generation, absolutely.

Fourth generation nuclear solves a lot of the problems that we were worried about.

If something goes wrong, plants will shut down safely rather than melt down.

They don't create very much nuclear waste.
