CONCLUSION
The study a empts to
understand the waste associated
with wind energy in terms of its
quantity generated and its
management. While studying
the global scenario, it was found
that the installations of wind
energy are consistently
increasing around the world.
Total installation power is
expected to reach about 840GW
by year 2022. A lot of variation
was observed among the
countries with respect to
installed power e.g. top ten
countries contribute more than
80 % of the global wind energy
production in the world. In
India, although total potential of
wind power is 292 GW at 120m
(agl), total installed power is
only about 38GW as of February,
2021. Therefore, a lot of
development can be expected in
the near future in wind energy REFERENCES
in India and in the world as a
whole. Although development
of wind or any other renewable
energy is the need of the hour,
one also needs to notice the
environmental impacts
associated with any technology.
In case of wind energy, the
turbine blades are the major turbines'
problem at the end of their life. Quantification
For India, total waste generated characterisation of future waste growth
from wind energy has been
estimated to be around 1.1
million tonnes by year 2050. The
study also deliberates on
reuse/recycling of these blades
