The need of the hour is to find
sources of renewable or virtually inexhaustible
energy as the present natural sources of energy
fossil fuels and coal are being depleted. By the
use of these energy sources we are polluting the
environment due to which Ozone layer is
becoming thin day by day causing threat of
infiltration of UV rays.
The sources like fusion involve
the generation of large amounts of waste heat
which is causing stress on ecosystem.
Hence, we have to go for alternate
source of energy that is renewable and pollution
free and the topic of the section is Wind energy.
