Question 5:
Compare and contrast bio-mass and hydro electricity as sources of energy.
Answer:
Bio-mass and hydro-electricity both are renewable sources of energy. Bio-mass
is derived from dead plants and animal wastes. Hence, it is naturally replenished.
It is the result of natural processes. Wood, gobar gas, etc. are some of the
examples of bio-mass.
Hydro-electricity, on the other hand, is obtained from the potential energy
stored in water at a height. Energy from it can be produced again and again.
It is harnessed from water and obtained from mechanical processes.
