In theory yes, but the fossil fuel industry has set up elaborate to make that not true.
For example, when switching from mostly-gas powered district heating to a heat pump, I had to pay several thousand euros to get it disconnected. It was literally a guy coming over for 10 minutes.
My district heating is also cheap per GJ, but very expensive per month, meaning it barely pays to use less. So I couldn’t JUST switch to heat pump heating and keep the hot tapwater, because that’s a financially terrible move. So I had to have an entire hot water system installed as well, costing even more money. And I was lucky enough my attic could hold a boiler, most can’t.
Now, I have that money, but the barriers in place are very high against it.
So yes, per joule of heat, it’s much cheaper. But in practice, they make it very expensive.
