GEOTHERMAL ENERGY PROS AND CONS
GEOTHERMAL ENERGY PROS AND CONS: THE COST OF GOING GREEN
JUNE 6, 2014, by WILL GEMMA
Geothermal energy isn’t new. Most people accept that it was invented (or discovered, depending on how you look at it) by Piero Ginori Conti in Italy in 1904. Others maintain it’s been around for 10,000 years. In either case, the major pros and cons of geothermal energy haven’t changed much in at least 100 years.
TAPPING THE EARTH’S HEAT
…But it has some environmental problems. The main concern is the release of hydrogen sulfide, a gas that smells like rotten egg at low concentrations. Another concern is the disposal of some geothermal fluids, which may contain low levels of toxic materials. Although geothermal sites are capable of providing heat for many decades, eventually specific locations may cool down…>>
A MICHIGAN COUNTY UNEARTHS SAVINGS WITH GEOTHERMAL ENERGY
Looking at the Kent County Correctional Facility in Michigan you would never know that underneath the complex is a technology that is saving taxpayers on average $100,000 a year…>>
HOW DOES GEOTHERMAL DRILLING TRIGGER EARTHQUAKES?
By Katherine Harmon
Despite the promise of cheap, clean power, geothermal energy development may be on shaky ground. There have been rumblings from residents and scientists alike that drilling deep to tap naturally occurring heat could cause bigger earthquakes….>>
WASTEWATER WELLS, GEOTHERMAL POWER TRIGGERING EARTHQUAKES
July 11, 2013 by CHRISTOPHER JOYCE
The continental U.S. experiences small earthquakes every day. But over the past few years, their numbers have been increasing. Geoscientists say the new epidemic of quakes is related to industrial wastewater being pumped into underground storage wells.
Now there’s new research that reveals two trigger mechanisms that may be setting off these wastewater quakes — other, larger earthquakes (some as far away as Indonesia), and the activity at geothermal power plants….Read more or listen to a 4minutes audio clip>>
