10 Disadvantages
- High Installation cost
- Can run out of steam
- Hard to transport to consumer
- Poisonous gases can seep from beneath the earth and be released into the air
- Only used in certain types of areas
- When the steam is being pumped out of the ground, it could go right back into the earth

Facts about Geothermal energy
- It's been around for over 2,000 years (founded on Lisan Mountain in China)
- The energy must be heated to at least 300°F
- No fossil fuels are need to produce
- Geothemal Energy at the moment is renewable, but if it becomes a permanent primary source could be gone
- We can make our own by using EGS (Enhanced Geothermal System) technology
