"Natural features such as hot springs, mud pools, sinter terraces, geysers, fumaroles (steam vents) and steaming ground can be easily, and irreparably, damaged by geothermal development."

"Certain studies have shown that a geothermal power plant that could be considered as economically competitive would cost at around $3400/kw installed. Yes, the cost of the construction of a geothermal power plant is much higher compared to a facility producing natural gas, however, the cost of electricity production of the two in the long run would be similar. Initially, the construction cost of the geothermal plant would be 2/3 of the total cost. On the other hand, with a natural gas facility, the cost of the fuel is 2/3 while construction cost is just 1/3 of the total cost.  So this is where geothermal power plant and natural gas energy come into a standoff. In the long run, production rates stabilize and the cost of production for both plants become competitive. One good thing about the pric"

"Pollution free production of energy. Since geothermal energy does not require fossil fuels to be burned, production of electricity using this type of energy can be considered as pollution free. Sometimes, there is the tendency that this could release some harmful gases from beneath the earth that might actually be harmful. However, these gases could be contained."
