Geothermal Energy Disadvantages

Potential emissions – Greenhouse gas below Earth’s surface can potentially migrate to the surface and into the atmosphere. Such emissions tend to be higher near geothermal power plants, which are associated with sulfur dioxide and silica emissions. Also, and the reservoirs can contain traces of toxic heavy metals including mercury, arsenic and boron.

Surface Instability – Construction of geothermal power plants can affect the stability of land. In January 1997, the construction of a geothermal power plant in Switzerland triggered an earthquake with a magnitude of 3.4 on the Richter scale.

High cost for electricity – Total costs usually end up somewhere between $2 – 7 million for a 1 MW geothermal power plant.

High up-front costs for heating and cooling systems – While there is a predictable ROI, it will not happen quickly.For an average sized home, installation of geothermal heat pumps costs between $10,000 – $20,000 which can pay off itself in another 5-10 years down the line

Location Specific – Good geothermal reservoirs are hard to come by. Iceland and Philippines meet nearly one-third of their electricity demand with geothermal energy. Prime sites are often far from population centers.

Distribution costs – If geothermal energy is transported long distances, cost can become prohibitive.

Sustainability questions – Some studies show that reservoirs can be depleted if the fluid is removed faster than replaced. This is not an issue for residential geothermal heating and cooling, where geothermal energy is being used differently than in geothermal power plants.

Cost of Powering the Pump – Geothermal heat pumps need a power source. 

May Run Out of Steam: You have to be incredibly careful when you are trying to check everything that is related to geothermal energy. Mind must be taken to watch the heat and not to abuse it, because if the heat is not taken care of properly, it can cause a meltdown or other issues where the energy is not properly distributed or used.
