Lack of inexpensive, reliable energy delivery is one of the chief obstacles to growth and development in sub-Saharan Africa. Nearly seventy percent of people living in the region lack access to electricity, forcing them to spend significant amounts of their income on costly1 and unhealthy forms of energy such as diesel2 fuel to run generators3 and kerosene4 for lanterns.

But if there is one thing Africa is not lacking, it is sunshine. And that means a lot; indeed, for some of the world's poorest people, it makes all the difference in the world.

A little more than a year ago, Power Africa-- a U.S. Government initiative coordinated5 by the U.S. Agency for International Development, or USAID--and Power Africa's partners, the United Kingdom Department for International Development, Shell Foundation, and the African Development Bank, launched the Scaling Off-Grid Energy Grand Challenge for Development, with a focus on pay-as-you-go solar home systems. The Challenge's goal is to provide 20 million off-grid households in sub-Saharan Africa with clean, affordable6 electricity by 2030. So far, the Challenge has made 40-plus investments in early-stage, off-grid energy companies, which are expected to result in some 4.8 million new electrical connections.

One reason for the success of the start-up companies that have won grants from the Challenge is the fact that the cost of solar technology is falling fast, so it is within the means of those who live away from traditional power grids7. And thanks to the new system of mobile money and pay-as-you-go financing, they can purchase the solar power-generating equipment they need and pay for it in daily installments8 from their telephones, for as little as 15 cents a day.

Thanks to these technological9 and financial innovations, many people are getting electricity for the first time, every day. In these newly-electrified communities, businesses can flourish, clinics can safely store vaccines10, and students may study long after dark. Indeed, access to clean and reliable electricity can enable entire communities to escape the cycle of extreme poverty.

The Scaling Off-Grid Energy Grand Challenge for Development partnership11, solar technology, and companies that bring light and electricity to off-the-grid homes and businesses, are revolutionizing daily life for millions of people in sub-Saharan Africa.
