From Combustibles
to Renewables : Opportunities & Challenges

Revised Assessment
of Renewable Resources
in India
Power & Energy Scenario in India
Base load is invariably provided by combustible fuels
Combustion based electricity supplies more than 3/4th of electricity demand of our country
More than half of the capacity addition for power generation is in the form of coal based power plants
Greenpeace estimates the coal reserves of India to last only for 17 years
Resources & References
Solar Power Potential
Wind Power Potential
The Potential for wind power generation for grid interaction has been estimated at about 48,500 MW taking sites having wind power density greater than 200 W/sq. m at 50 m hub-height with 1% land availability in potential areas for setting up wind farms @12 ha/MW.
About 5,000 trillion kWh per year energy is incident over India's land area with most parts receiving 4-7 kWh per sq. m per day. Hence both technology routes for conversion of solar radiation into heat and electricity, namely, solar thermal and solar photovoltaics, can effectively be harnessed providing huge scalability for solar in India.

102788 MW @ 80 mtr Hub height
