State any two impacts on the environment caused due to the increase in energy demand. Suggest any two steps to reduce energy consumption.

(N/A) Modernisation and industrialisation have increased the demand for energy. This has resulted in the following:
Consequences:
$(i)$ The increase in the demand for energy has led to excessive exploitation of energy sources,which has disturbed the environmental balance.
$(ii)$ The increase in the demand for energy has led to the excessive use of conventional energy sources,which are limited in nature,causing a partial energy crisis.
Steps to reduce energy consumption:
$(i)$ Judicious use of energy and avoiding the misuse of energy can significantly reduce consumption.
$(ii)$ Alternative sources of energy,such as solar energy,wind energy,hydro energy,and tidal energy,should be used to reduce the burden on non-renewable energy sources.
