I wanted to say that the integrated urban energy systems approach could be cost-effective immediately. We're not trying to push any one technology, but it's an approach to planning that provides for all of this distributed power generation and consumption to be happening.
We just heard about how, in the city of Ottawa, there's a local distribution agent. The grid can only accept so much distributed power. If you're building the grid from a starting point, it doesn't necessarily cost more than a classic grid, but it does enable people to participate in the consumption and generation of power to achieve a net-zero objective utilizing solar and agricultural waste and all that. It's an approach that, given the circumstances, might be cost-effective immediately.
The other thing is that, when you're doing that, what you're trying to do is not so much improve efficiency for the sake of efficiency; you're trying to eliminate waste, so hard-earned dollars are not going up in smoke.
