There is something close to that in downtown Toronto--the Enwave project--a cooling system in downtown Toronto for the huge buildings. So we have examples in Canada of similar projects for energy storage and for the optimization of heating and cooling systems. I'm not aware of any other big projects like that elsewhere, but there are smaller ones.
I think the biggest problem right now in this country is that we have always approached energy policy in silos. We look at oil, we look at gas, we look at wind, we look at solar, and we look at geoexchange in silos, and we don't look at the interaction between all those energy forms.
There have been a few questions about how we are going to put all this power on the power lines and how we are going to replace all those power plants 10 or 15 years down the road. I think the true question is how we can optimize the energy system as a whole. Then we'll find a place for geoexchange, for example, in projects where we're displacing heat or cooling, for example, like in the Stockholm project. We can optimize the rest of the system when we look at where the energy is consumed.
Why do we produce energy anyway? It's because we need a service at the end of the pipeline. And the services are heating, cooling, and lighting, and things like that.
Robert just touched on this point. Rather than looking at how to put more energy into the system, let's start the other way around. How can we save it and optimize it at the consumption level? And then we just go back up to the origin of the energy, and then we have optimization.
