Question 2:

Why are we looking at alternate sources of energy?

Answer:

Fossil fuels, which have been traditionally used by human beings as an energy

sources,are non-renewable sources of energy. These sources of energy are

limited and cannot replenish on their own. They are being consumed at a large

for alternate sources of energy.
