Advantage
There is no wastage or generation of by-products.
It is not dependent on the weather conditions.
Advantage
Disadvantage
Drilling into Heated Rock s Very Difficult. There is always a danger of eruption of volcano. Installation cost of steam power plant is very high. It may release some harmful, poisonous gases that
can escape through the holes drilled during construction
