A hot-water system in the right conditions works really well. There are different ways. The thing about saving energy is that you'd have to attack it from all sides. If you went to heat pump chillers, let's say, we have some at Les Terrasses de la Chaudière that have operated for many years. They work great. They actually produce 60°C water, and they produce your refrigeration at the same time, so everybody wins.
We have electricity right at the gate. Hydro Ottawa just bought that dam. I mean, it's right by the plant. We can be supplied right there and have a combination of heat pump chillers and boilers. You'd still require boilers because of our extreme temperatures, to boost the temperature up in the winter months. I think it's that combination you'd have to look at, and it would give you a better, greener source of power.
Steam itself, if it's run right.... We have to remember that when we had that accident in 2009, they essentially got boilers that were out in a field. They were sitting in a farmer's field in the States and they brought them up. Can they be more efficient? Absolutely. We have no economizers on them. There are so many different parameters on that equipment that could be upgraded, which would increase our efficiencies tenfold. The free cooling is another one. Why aren't we doing that?
