Deep reductions in emissions will involve revamping the major appliances in the home, such as the water heater, furnace and air conditioning unit. As these items become older, they become wasteful and they will need to be replaced by more efficient appliances that run off clean electricity.
Some of these replacements will be relatively innocuous, such as the installation of heat pumps, which will be in the basement or on the side of the house. Heat pumps work on principles similar to a refrigerator, shifting heat from outdoors indoors and vice versa. They can heat and cool your home and can also heat your water with an efficiency rate four times greater than a gas-powered version.
