We're talking about conventional geothermal. The roadblocks are financial: Convincing capital to be deployed within geothermal is a huge problem.
The federal government has been deploying capital into projects. There are three electrical generation projects supported by the emerging renewable energy program. Those are DEEP in Saskatchewan; Alberta No. 1 in Alberta—I happen to be the CEO of that one—and a project called Tu Deh-Kah in British Columbia.
However, on the question about the carbon tax, in Alberta No. 1, our financial model is built on three pillars: One of them is carbon taxes, one is the sale of thermal energy and the other is the sale of electricity. Currently we have to price that sale of thermal energy at a discount to natural gas. This makes geothermal very difficult in terms of competition with natural gas and other forms of electrical generation.
If we're talking about this new generation of advanced and engineered geothermal systems, these are, right now, very costly, but I want to focus on conventional geothermal, of which—
