As much as MP Barlow was bringing forth the idea of abandoned wells, and I expanded that to mean orphaned and suspended wells, mines are.... Cumberland Energy Authority in Nova Scotia is actually Canada's premier example of repurposing an old mine. We have thousands of mines. They're not very hot, but we all know that they fill up with water. When they fill up with water, because that water is terrestrial, coming from the earth, it is actually about 30°C, and 30°C is all you need for heating.
We don't necessarily want to make power everywhere. I think wind and solar are doing a wonderful job helping us transition to renewable electricity, but renewable heat is something that we're not addressing at all. In fact, we're actually pumping it and paying to dispose of it, as you know, from abandoned mines.
Working mines and abandoned mines are some of the lowest-hanging fruits we could go after. The towns are in place. The customers are in place. We've already drilled, in some cases, or done open-pit mines. We've flooded the mines and are pumping to get rid of it. Now you need one piece of equipment, which is a heat exchanger, to take the heat from that water and put it to purposeful use.
