3. How does it Work ?

4. What are the Positive effects ? 1.It is completely clean, no waste at all. 2.After the power plant is built, the energy is almost free. 3.It doesn’t create so much pollution. 4.You can only see a little bit the impact.

5. What are the negative effects? 1. It can run out of steam: like hot rocks can lose their heat. 2.It’s very expensive to build geothermal power stations. 3.It’s hard to find a place where hot rocks or lakes are under- ground. 4.Sometimes some gasses and minerals may come up.

6. How did we discover it? It is known that geothermal energy was discovered more than 10 000 years ago. It was discovered in North America by American Paleo Indians.
