It always baffles me to see how the rest of the world seems oblivious to modern heat pumps. They come in a variety of medium (air-air, air-water, geothermal-water). Seeing how heating a house is the biggest energy expenditure it should be a no-brained to heat homes with heat pumps.
To give a concrete example, In Northern Sweden, above the Arctic line, a modern geothermal heat pump an warm a 200 m2 (~2000 sq feet) house for a year, including warm water, for 15000kWh. Using gas, the need would be 4x higher. Even if you use electricy made from coal, you’re still coming out ahead.
