Energy is the backbone of all our progress and
development.the world depends greatly on fossil
fuels.fossil fuels such as oil.gas and coal are very
cheap and competitive with all other sources but
they are a main cause of climate changes as they
emit co2 which works as agreenhouse.also,this
energy will soon run out as it is non-renewable.
so the world is trying hard to find other alternatives
to fill energy gap.but all the present ones are
inefficient and scientists are working hard to
develop a new safer type of nuclear energy.
