Alternative Energy

The regions under the earth’s crust are hot and as we all know that is the very source if geothermal energy. The steam from these hot areas is used to drive the turbines which in turn power the electric generators.

Locations

The biggest disadvantage is that there are not many locations that are suitable for the geothermal energy harvesting and an accompanying power plant. The best location for a geothermal energy plant is when the rocks are hot and are at depth which is suitable for drilling. The rocks should also be soft enough to be drilling properly.

Longevity

The problem with geothermal energy is that there are temporary times when the locations just run out of steam, the problem may last for month sand for such times there is no production of energy as there would be no steam and thus no energy.

Transportation

Geothermal energy is a difficult thing to transport. The medium of oil can be easily transported but geothermal energy is very difficult to transport and thus can be used only for the purposes of energy generation for the nearby areas. The energy generated is also minimal as compared to the regular sources of energy. The substances released are also a cause for major concern for the environment.

Hazardous Materials

The biggest concern for environmentalists is the gases and materials released from deep within the earth’s centre. The gases and minerals released are more often than not hazardous. The biggest concern is for hydrogen sulfide. It is a very corrosive gas and is very difficult to dispose off properly. The minerals which cause concern are: - arsenic, mercury, and ammonia. The danger or earthquakes is also increased when drilling for geothermal energy.

Earthquakes
The geothermal energy harvesting can cause earthquakes in the region. The statistics clearly say that there is a definite increase in the recurrence of earthquakes in the region of geothermal energy harvesting.
