Trane notes that geothermal systems typically operate with such efficiency that they can return up to four dollars of heat for every dollar spent on electricity. These systems can also be configured to reduce the need for energy for water heating used for washing dishes, bathing, and laundry.

SunSource Home Energy Systems by Lennox harness solar energy to reduce the electricity consumed by residential air conditioning units or heat pumps. These systems also use that solar energy to operate other devices in the home, such as appliances, when the heating and cooling system is not running. In addition, if the system generates more power than is used by the home, that power can be sent back to the utility, which may entitle the homeowner to a credit on their electric bill.
