Sunlight is arguably the most abundant clean source of energy that is capable of enabling “indefinite” and sustainable economic growth, with minimum detrimental impact on the environment. Crystalline silicon solar cells have been continuously advancing in efficiency and reducing in cost of fabrication over the last 40 years, and in some locations in the world at the current prices, they are capable of producing electricity from sunlight at a comparable cost to the price of electricity generated from fossil fuels.
