During the summer climate-master geothermal heating and cooling systems absorb heat from your home and transfers it to the underground loop where it is then absorb by the cooler part of the earth.
where is Geo-thermal used in the USA
California is the site of most geothermal capacity,but since 2001 new geothermal capacity additions have increased and located in other western states. California has been develop already. (clean technical)
How much electricity does Geo-thermal use
Geo-thermal energy in the united states generated a record of about 16.792 million megawatt-hours in 2012, narrowly beating the previous record of 16.798 set in 1993 in 2012.
Advantages of Geo-thermal
Geo-thermal energy is generally consider "environmentally" friendly and does not cause significant amounts of pollution. Geo-thermal reservoirs are naturally replenish and therefore renewable cite is not possible to exhaust resources.
disadvantages of Geo-thermal
since this type of energy is not widely used therefore the "unavailability" of equipment,staff,infrastructure,training pose hindrance to the installation of Geo-thermal plants across the globe.
