Heating a home with a heatpump is a net win compared to gas in many parts of the world even when the electricity required is made with gas. The reason is that the heatpump moves heat (from outside to inside) which is more efficient than generating heat directly. Obviously there needs to be a plan to upgrade the grid to deal with electric heating, cooking, cars, etc.
