Moving to All-Electric Homes
A key technology for moving from gas-heated to electric heated homes and buildings are heat pumps.
Air source heat pumps have improved in efficiency and in cold weather performance in recent years. Ground source heat pumps use the stable temperature of the ground to provide heating and cooling.
To transition existing homes from gas to electric, and to build all-electric new homes, heat pumps, along with electric water heaters, will be needed. But replacing a gas furnace with a heat pump is an expensive proposition, even if the finances make sense over time.
Additionally, energy efficiency measures, solar thermal heating systems and passive solar design all have important roles to play. Finding innovative ways to finance and subsidize the transition will be a key policy challenge. Watch for bills in the Colorado legislature and elsewhere this year addressing this challenge.
