Geothermal Energy Pros and Cons

Greentumble

Geothermal energy is energy contained beneath Earth’s crust. What is geothermal energy? Geothermal energy comes in the form of heat produced within the Earth. How is geothermal energy produced? Hot springs, mud pots, steam vents, geysers are all natural outlets of geothermal energy. Later, with the greater knowledge of geology and availability of sophisticated mapping tools, we have learned to find geothermal reservoirs located even miles underground.

So You Think You Might Like Home-Based Geothermal Energy?

Green Home Blog

As one informative web site notes, geothermal’s power source never varies – at least on the human scale of plus or minus 75 years. More important, geothermal energy provides more than half the energy needed to deliver heating and cooling, whether in the Deep South or the frigid northern half of the United States. These geothermal fields currently exist in California and Oregon, with more across the Pacific Northwest as far inland as Montana in the north and New Mexico in the south.

Geothermal Heat Pump: How Does It Work

Greentumble

Today, geothermal energy is probably one of the least talked about forms of renewable energy. Geothermal energy uses the earth’s high temperatures for heat particularly during winter and it can also use the earth as a heat sink for cooling in the summer [2]. Geothermal doesn’t do that.
