MarketWatch commenters add to the great debateGood luck with getting Canadians to ditch their gas guzzlers. Subsidies for EV's aren't the answer as governments have no money. Rather than increasing our debt, it is more efficient to institute a carbon tax. This will reduce fossil fuel use and make carbon free energy sources more desirable. The extra revenues could reduce our deficit and make it possible to lower business taxes, increasing Cdn profitability and competitiveness. As near as has been able to be calculated, the total CO2 utilization of an EV, over its entire lifetime, is about 1/2 that of a comparable ICE vehicle. (This is hard to calculate precisely because so few EVs have actually reached the end of their useful 'lives', and there are so many variables that need to be included. For example, natural gas used to create electric power is shipped in very efficient pipelines, and the electricity created sent to EVs is transmitted via electric power lines whose loss is around 6%, while gasoline comes from oil shipped in VLCC ships, and is sent to gas stations via semi-trucks in a less efficient process.) GLTA!
