Question

Explain the differences using the points in the brackets.

(availability, environment-friendliness, advantages, and drawbacks)

Hydel power and power from geo-thermal source

Answer 1

Points	Hydel Power	Geo-thermal Power
Availability	Hydel power can be generated from running water, hence is easily available.	Geothermal power can be generated from hot water springs; hence, it is not easily available.
Environment friendliness	It is a relatively environment-friendly resource	It is a relatively less environment-friendly resource
Advantages and Drawbacks	The water used to generate power can be reused. The cost of developing technology is lower as compared to the development of a geothermal power plant.	The heat from the earth’s interior is utilised, which would otherwise not be used. The cost of developing the technology is higher as compared to the development of hydroelectric power plants.
