Clean Coal
There are a lot of people betting on "clean coal" tecnnology. The Chinese, of course, don't care much about clean fuel. Their air quality is terrible. Canada was and probably still is selling them lots of coal.
Coal is still very abundant and there's lots of it that is very accessible.

The Ontario government was promising to get rid of coal-fired power stations.
We are going to see a lot more nuclear energy in the future.
