Using a heatpump likely actually worsens CO2 impact, as most utilities providing the electricity don’t run on green energy.
E.g. you can either burn natural gas directly, or use electricity the Utility generated by burning natural gas. Or even Coal in many cases.
But that’s speaking more to the impact today. In the long run electrification across the board is required to reduce emissions.
- manmal 4y agoReally depends on where you live. In Austria, it’s cleaner to use a heatpump.
- adam_arthur 4y agoLooks like Austria's mix is quite clean, mostly Hydro Power: https://www.statista.com/statistics/1234896/austria-distribution-of-electricity-production-by-source/#:~:text=Hydropower%20is%20the%20main%20source,in%20terms%20of%20renewable%20output https://www.statista.com/statistics/1234896/austria-distribu....

- ttyprintk 4y agoDisregarding differences in NG price between utilities and households, I see different numbers than that. 60% efficient NG turbines, onto a 85% grid, and a 2.6 COP at home means no NG furnace can compete until the weather hits winter lows. I don’t see how it can make it worse.
