Actually, we have been working with CanREA, the Canadian Renewable Energy Association, and the answer is clear: Right now Canada has one of the cleanest grids in the world, with 82% non-emitting production of electricity and 67% renewable electricity. So it is possible to produce more clean electricity for us to have an all-electric grid that will be clean and sufficient to produce enough electricity for the whole fleet of vehicles in Canada.
