Sure. Springhill was a beneficiary of geological survey of Canada funds. This is going back a few decades. It was one of the poster-child projects they funded. Currently Springhill, Nova Scotia, through the Cumberland Energy Authority, has a district heating system. There are many small businesses on the system, including a greenhouse and a plastics manufacturer. You can see the variety of different commercial and industrial uses for that heat.
If you think about a place like Nunavut, a couple of weeks ago it was -26°C. Maybe Nunavut doesn't have Canada's greatest geothermal resources, and maybe Nunavut cannot make electricity, but can they get 30°C water that can bring, as a preheat, energy up to that level, and then perhaps still need diesel to top it up to take it to a more useful level for electricity? Absolutely. What we've done is we've taken it to about 50°C. A diesel would have had the supply; instead, it does it more naturally with geothermal. So even in places where you can't replace diesel or natural gas with geothermal, you can at least do it as a pre-treatment and significantly address the volume of fossil fuels that are being burned.
Back to the question around imagineering, there are currently over 200 uses of geothermal in the world, everything from livestock heating to the greenhouses, the fish farms we talked about, cement kilns, pulp and paper, and even heating roads and sidewalks to cut down on accidents and insurance claims as well as to make main street more vibrant so people could actually shop at any time. That's what Iceland has really pioneered. If you go there at any time of the year, there's no snow in the downtown core, because they're piping this kind of waste heat that costs very little to use, but it actually increases their economic activity downtown.
If you can think about it, it can be done. Why don't we do it in Canada? Sometimes it's permitting and sometimes it's this kind of parity we don't enjoy with the other renewables. But really, we're not being entrepreneurs in this sense. We need to tell people that the resource exists, the skills exist, and it's available. We say, “What would you do with the heat?” The best answer I ever heard to the question, “What would you grow with geothermal energy?” was “a whole community”.
