Disadvantages

The disadvantages of this energy source to the community/environment:

• to use geothermal energy effectively, we need to learn more about controlling the expansion of fissures in deep rock formations and how they might react after the extraction of large amounts of heat
• digging process is very costly; huge financial investment
• most often requires leasing of land to install the pipes (unless its one’s home)
• deep drilling operations may cause earthquakes or volcanic activity
• bringing underground water to the surface could contaminate local water supplies and the ground
