Shell Day Unconventional Gas Footprint Reduction Challenge
Solar Power For Poor
1.
2. INTRODUCTION
• Solar technologies are broadly characterized as either passive or active.
• Conventional energy is finite and fast depleting. On the other hand, the
demand for energy is rising exponentially. Extensive use of solar energy is
the only way to address this dichotomy. The energy which hits the earth from
the sun in one hour is than the whole world uses all year. Yet only a fraction
of it is harnessed. If every household or institution sets up its own power
generating station to capture the infinite and abundant energy of the sun. We
would be successful in meeting their own power requirements but they would
actually have excess power that they could 'sell' back to the grid.
6. COMPREHENSIVE SOLAR ENERGY POLICIES
• Solar tower must be a part of 300 MW solar farms supplying for almost
700,000 homes.
• Attention to 50 MW CSPs that use molten salt technology.
• Stirling engine based power plants.
• Use of Fresnel lenses
7. COSTS/FINANCIAL ASPECTS AND OTHER POSITIVES
• Costs are projected to drop to Rs. 17 to 23 per kilowatt hour in India when
capacity exceeds 3,000 MW.
• Early CSP plants required water to cool the system but now technology is
able to use air to do the cooling.
• CSP can be used for desalinating brackish water or seawater which is again
a boon for places like Gujarat and Rajasthan.
• These plants don’t need any new materials or technology.
• flat land and proximity to the load center plants.
