Cut 75 Percent Off Your Electric Bill

100's of people are saving money and learning the best way to beat the utilities at their own game. You can too!


Category Archives for "Geothermal" The industry of geothermal heat exchange has been around for years. Actually, the Greeks used geothermal heat to heat their hot baths a couple of millennia ago. Geothermal heat as we now apply the term refers to the art of extracting latent geothermal heat from the ground. closed loop geothermal Geothermal resources are reservoirs of hot water that exist at varying temperatures and depths below the Earth’s surface. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including electricity generation, direct use, and heating and cooling. In the United States, most geothermal reservoirs are located in the western states.

Benefits of Geothermal Energy

  • Renewable—Through proper reservoir management, the rate of energy extraction can be balanced with a reservoir’s natural heat recharge rate.
  • Baseload—Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions.
  • Domestic—U.S. geothermal resources can be harnessed for power production without importing fuel.
  • Small Footprint—Geothermal power plants are compact; using less land per GWh (404 m2) than coal (3642 m2) wind (1335 m2) or solar PV with center station (3237 m2).*
  • Clean—Modern closed-loop geothermal power plants emit no greenhouse gasses; life cycle GHG emissions (50 g CO2 eq/kWhe) are four times less than solar PV, and six to 20 times lower than natural gas. Geothermal power plants consume less water on average over the lifetime energy output than the most conventional generation technologies.**
This archive focuses on focuses on harnessing this clean, domestic natural resource to generate electricity by accelerating near-term hydrothermal and low-temperature adoption and boldly pursuing EGS as a transformative player by creating a commercial pathway to large-scale, reproducible systems.

Geothermal Heating and Cooling Systems: Choosing The Right One

​​​​​​What are Geothermal heating and cooling systems?Geothermal heating and cooling ​systems harnesses the Earth’s heat. Just a few feet below the surface, the Earth maintains a near-constant temperature, in contrast to the summer and winter extremes of the ambient air above ground. Farther below the surface, the temperature increases at an average rate of approximately […]

Geothermal Heating and Cooling: Not as Far-Fetched As It Sounds


“​Geothermal can be a huge source of energy very quickly.”​David Suzuki ​Geothermal heating and cooling has been in use by humanity since the paleolithic period. It continues to be used today. In 2004 more than 70 countries were taking advantage of geothermal heating for heating their homes and even for growing gardens. What is Geothermal […]
