It's expensive compared to heat pumps, especially if you also want air conditioning.

According to the IEA [1], 43% of the energy consumption is oil (transportation, heating), 18% is natural gas (mostly heating), and 25% is electricity. Switching to resistive heating would require doubling the electricity production. Using heat pumps is much more efficient.

> Why not resistive heating?

Because France has a massive dependency on nuclear power... of course resistive heaters are cheaper than anything else when you got a ton of NPPs around. But their plants are all aging and are a nightmare to keep operational, so if they'd switch over to heat pumps their total energy demand would go down drastically.

Heat pumps reduce electricity usage by at least 3x and also provide cooling.

They lose out on export revenue
