While the grid is transitioning to renewable energy, the carbon emissions of buildings have remained flat in recent years. A large portion of these emissions is due to space heating, which is most often provided by fossil fuels, particularly in colder climates. Heat pumps are critical for electrification, since they are so much more efficient than electric resistance heating, they achieve a similar cost of heating to a gas boiler and a much lower cost of heating than an electric boiler, while greatly improving efficiency and reducing emissions.
