I'll also let the innovation angle speak to this. I won't speak to carbon pricing per se, but we do see the significant returns of energy efficiency at the industrial level.
I have a specific example. We found that in one case an investment of $50,000 through a contribution to an energy management system yielded $2 million in energy savings in a business over time, so when you look at a powerful multiplier such as that—and that's the energy management itself—it's not the big innovation pieces, but by supporting innovation in real time we're helping to reduce the immediate expenses while also making available technologies that will support the long term.
If I can use the analogy of seeing where the puck is going and skating toward it, in the short term the energy efficiency shores it up and in the longer term the innovation is the—
