Advantages

・ Net domestic energy・ Fuel cost is zero.・ Renewable energy・ Emits very little CO2 →Easy on the environment・ Almost infinite amount of energy・ The high rate of operation →Stable supply of energy

Disadvantages (Issue)

・ Development for a long period → cost a great deal・ Development is difficult.・ Deplete of hot spring resource ・ Occurrence of landslide・ Risk of induced earthquake・ Air pollution from hydrogen sulfide・ Spoil the sight

In future

Geothermal energy is a very attractive.But this is bristle with issue.In fact

we should be moving across the country.

Thank you for listening.
