This is already being done in some countries (e.g., the Netherlands), but it is just a (necessary) part of the puzzle. The existing housing stock needs solutions too, and installing heat pumps in older terrace housing is far from ideal due to noise pollution, cost, lack of space, and a limit to what can be done in terms of insulation. Geothermal plants can be used to provide district heating, which is a much better fit for certain types of houses.
