7. Energy scenario
• India is presently the world’s fourth largest economy as far
as Purchasing Power Parity (PPP) terms as concerned (the
GDP in PPP terms is estimated at approximately USD 3.2
trillion) and the fifth large energy consumer in the world
• By the year 2020, oil and natural gas will meet 44 percent
of India’s energy requirement compared to 50 per cent by
coal
• Nuclear and hydel energy would form 2.5 percent and 3.5
per cent, respectively
• Natural Gas may form 14 per cent of our energy needs in
2020 compared to 8.6 per cent today.

8. HYDEL
• India has a total hydro energy potential of
about 1.5 lakh MW of which about 20 % is
installed
• Small hydro plant potential is about 15000
MW and most of it is in the northern and
eastern hilly regions.

9. Wind
• The wind power potential of India is about 45,000
MW
• out of which capacity of 8748 MW has been
installed
• in India.
• India is one of the leading countries in generating
the power through wind energy.
• Gujarat, AP, Karnataka, MP and Rajasthan are
states having more than 5000 MW potential each.

10. Solar
• India intends to implement a comprehensive and
rigorous renewable energy plan, it emerged on August
4th 2009.
• Through harnessing the power of the sun, India’ plan is
to have electricity from solar energy feeding 20 GW
(gigawatts) into the national grid by 2020.
• 20 GW represents a huge amount of electricity. To put
it into perspective, the IEA (International Energy
Agency) envisages that, by 2020, total worldwide
capacity from solar energy will be around 27 gigawatts.
• On this basis, then, India’s solar electricity will
represent approximately three quarters of this
