Success in scaling-up solar energy in Rajasthan, India
Solar power is attractive because it is abundant and offers a solution to fossil fuel emissions and global climate change. Earth receives solar energy at the rate of approximately 1,20,000 terawatt. This enormously exceeds both the current annual global energy consumption rate of about 15 TW, and any conceivable requirement in future. In fact, solar energy is the largest exploitable renewal resource as more energy from sunlight strikes Earth in 1 hour than all of the energy consumed by humans in an entire year. Use of Solar energy is also requirement of the day because the fossil fuel reserves are rapidly depleting and greenhouse gases and are to be substantially reduced to limit the carbon emission from the power sector in near future.
