Green Energy - Geothermal Cooling

Greenhouse - Green Energy - Geothermal Cooling

Geothermal CoolingWhen having a conversation about using Geothermal means to conserve electricity normally consumed by energy hungry air conditioners, it's helpful to make a distinction between Geothermal Energy and Geothermal Cooling. Often the term Geothermal is used interchangeably in the same conversation without actually making a distinction of what process will be used to conserve natural resources and significantly lower your electric bill.

Geothermal Energy - Heat radiating from the Earth's molten core is called Geothermal Energy, which interfaces with cooler elements in the earths crust to create Geothermal Activity. Naturally occurring Geothermal Activity like steam that is used to generate electricity. Areas of the world closer to Earth's core are more likely to have easier access to the vast resource of Geothermal Activity to produce electricity by using Geothermal Power Plants.

  • Iceland known for its vast landscapes, peppered with warm springs and geysers, has the most abundant access to Geothermal Activity.
  • The country has taken a lead in Geothermal Energy, by using their renewable resource to cleanly generate almost 30% of their annual electricity consumption.

1% of global electricity consumption is generated by Geothermal Energy. So it is very unlikely that most people will have a choice whether or not to use this Geothermal Energy as a means to conserve natural resources and reduce pollution created by the burning of fossil fuels. However, homeowners can still harness the stable characteristics of the earth to reduce the amount of electricity consumed for cooling a household.

Geothermal Cooling is the process of circulating warm household air through the cooler soil in the yard and pumping it back into the home. The Environmental Protection Agency (EPA) has named Geothermal Heating and Cooling Pumps "the most energy-efficient and environmentally sensitive of all space conditioning systems." It has been estimated that Geothermal Pumps can cool homes 20%-50% more efficiently than traditional compression-based air conditioners. This could mean over $1000 of savings per year in electricity costs!

  • Closed Geothermal Cooling consists of one or two networks of tubing that are buried in the yard and another network of tubing that circulates through the home. Both indoor and outdoor tubing at vacuum sealed and attached to Geothermal Pump. Much like a refrigerator uses coolant to push out warm air; a Geothermal Pump uses coolant to exchange warm air inside the home with cooler air located in the network of tubes in the yard. This is known as a closed system that is most widely deployed.
  • Open Geothermal Cooling uses cool water drawn from a water source like a pond or well to cool the air. This system is an even more efficient way of cooling since water has a constant temperature cooler than the average ground temperature.
