Aug 12, 2016international finance corporation has shared the link and says "International Financial Corporation: How Lighting India Empowers Women through Off-Grid Solar Solutions - Nearly 80 million Indian households - or approximately 400 million people - still use kerosene as a primary source of fuel for lighting. Kerosene is unhealthy, polluting, and expensive. Not only is it detrimental to people’s daily lives, the lack of efficient energy sources also limits educational and economic opportunities.
High-quality off-grid lighting and energy products offer a real and sustainable alternative to fossil fuels. A number of modern solar-lighting technologies that are cost-effective, reliable, and efficient have emerged globally over the past decade. Yet, they account for less than 8 percent of the energy market in India."
