        @paulg according to this report http://shrinkthatfootprint.com/wp-content/uploads/2013/02/Shades-of-Green-Full-Report.pdf … you can average it to 70 g CO2e/km vs petrol of 40g for build + ~130g drive

        @paulg it's a good question to consider. New tech isn't always better tech. we've only begun to imagine the implications

        @paulg electricity is simply an interface. When clean energy is powering the grid, the implementation will swaps, recoup time drops.

        @paulg To boil it down to "environmental load" (bsd on finite resrces): Load of petrol car is 4x of AvgElectric with a "green" source mix.

        @paulg (3 of 3) radio active waste in AvgElectr is highest and depends on the source mix of the electrical sources.

        @paulg biggest factor in determining that would be the way the electricity is produced. If from coal/gas, then no real advantage.

        @paulg If we had a set of taxes on environmental harm (e.g. a carbon tax) you could just look at TCO.

        @paulg depends on the location, in Alberta for example we are still powering our grid with 40% coal. Long time until we are net ahead
