During IE3 class in Tuesday, we read about geothermal energy in Japan. I understood that it is a good power source, but Japan is not using that much. I didn't know why so I did a research about it. There were about 8 demerits about geothermal energy. I'll put just three here.
1.It takes time to find a source, activate plant, and costs a lot(15~20years)
2.The source is under the national park and it is hard to dig it out
3.Poisonous gas come out and pollute atmosphere and soil
These are the three main demerit that making Japan hesitate using geothermal energy. Even though this is my idea. What do everyone think about geothermal energy?
