Why is so much natural gas used in the tar sands project?

    It is much harder to extract bitumen from tar sands and then to produce liquid fuel from it, compared to petroleum, and so requires a lot more energy. The necessary electricity and heat can be provided by natural gas. For example, you need to inject steam or hot air or some sort of solvents underground to make the otherwise very viscous bitumen flowing well enough to be pumped.
