Geothermal energy is a great option for both existing homes and homes that are being built, especially in a climate like Nebraska's where the continental climate around Omaha means summers are hot and winters are cold. While a house will need roughly four times as much heating as air conditioning over the course of a year, a large portion of the heating is required during the milder fall and winter periods. Have you considered geothermal?
Geothermal systems use warmth from the sun that is stored in the ground. Geothermal takes advantage of the fact that the ground temperature remains fairly constant throughout the year (right around 55℉), unlike air temperatures. This means a ground source heat pump can be up to 40 percent more efficient than an air source heat pump, as it can provide more heat over the course of the winter.
Geothermal systems are a great match with other renewable energy sources such as grid-tied solar electric.
Geothermal systems can be used to deliver heat to the house through ductwork or through a water-based system like radiators or radiant floor heating as well as providing hot water to your tap. They do this using a "desuperheater" to transfer waste heat to hot water. When the system is in cooling mode, domestic hot water is a byproduct of the thermal process. In heating mode, the desuperheater heats a portion of your hot water. Stand-alone systems that heat water year-round are also available.
Geothermal systems conserve energy and, because they move heat that already exists rather than burning something to create heat, they reduce the amount of toxic emissions in the atmosphere. Currently, installed systems eliminate more than three million tons of carbon dioxide. That's the equivalent of taking 650,000 automobiles off the road! Geothermal cooling also minimize ozone layer destruction by using factory-sealed refrigeration systems, which will seldom or never have to be recharged.
