> It is big number but now we have to produce same amount of energy in electricity. 79% of all electricity generation was fossil fuels.

Where are you getting that number? It's 63.6% in the US:

Moreover, most of the fossil fuel generation is natural gas, which emits less carbon per unit energy than gasoline and large scale generation is significantly more thermodynamically efficient than small gasoline engines. And heat pumps are significantly more thermodynamically efficient than oil furnaces.

Meanwhile power generation from non-carbon sources is growing at a fast pace while coal is dying out, so that number will only improve over the lifetime of the vehicle/heat pumps, and if you want to get ahead of the curve you can install some solar panels on your roof.
