There's not even a physics reason why a heat pump needs to be electric. There are gas-fired heat pumps. There are even gas-fired refrigerators. These weird anti heat-pump memes are just being regurgitated by people who do not understand what they are talking about.

A modern gas turbine is around 50% efficient, give or take 10%. A modern heat pump has a COP of around 4, so burning gas to make electricity to run a heat pump is more efficient than burning gas to make heat.
