So you're convinced that we do, but in general, most people I know in the energy world are not convinced we have a crisis and are running out of energy. We have enormous reserves of various fuels and we have ways to turn one fuel into another. You ask how to heat our homes. If climate wasn't an issue, we'd have lots of ways to do it. You can turn coal into synthetic gas at costs that are roughly competitive with today's gas prices.
There are plenty of different routes that we have with energy supply. We have to supply the fuels that we need to run our society. The problems that dominate our energy system, given the extraordinary resources that we have, are the environmental consequences of using those fuels, not the availability of the fuels. There are systematic reasons, well understood, for why forecasts by central governments underestimate the long-run conversion of resources to reserves, and those are that central governments don't account for the change of technology.
Unconventional gas reserves—either tight gas, hydrates, etc.—are not assumed to exist until they're turned into reserves, which means things that are economic. There are plenty of people sitting beside me in my department who are thinking very seriously about how to produce unconventional gas reserves from Mackenzie Delta or from offshore, and most assuredly those things are going to go. Whether production in Alberta goes up or down in the next little while I can't really predict, and I don't think it's really my job to predict. But in the long run, I think the idea that we're going to run ourselves out of gas is wrong. We're going to run ourselves out of atmosphere before we run ourselves out of gas.
