We saw the same sort of thing with Nortel, obviously, more recently.
Back to Professor Duguay. You talked, of course, about wind and solar power as alternatives to nuclear, and the concerns we've been hearing are twofold. One relates to the intermittent nature of wind and solar. You referred to cost-effective means of power storage, and I'd like you to talk about that for a moment, because we haven't been hearing about that.
Secondly, there's concern about transmission. As electricity is transmitted, it's depleted, and therefore we hear about smart grids. What's happening there to resolve some of these problems that we see, the concerns about wind and solar?
