Determined to make a difference, Wadongo designed an alternative – a simple, sun-powered lantern dubbed a MwangaBora, which means “good light” in Swahili. The lamp is cleaner and greener, and also cuts costs. “For a family that earns two dollars a day, kerosene takes about 30-40% of their daily income. If they’re able to save that, it really makes a big difference,” says Wadongo. The lamps are made from locally sourced scrap metal and fragments of solar panels that charge a battery-powered LED light, while a USB port can be built into the base, offering an easy way to charge phones and radios.

Instead of importing solar technology from a mass producing country such as China, groups of young people are trained to manufacture the lamps. These are then given to women’s groups, who use the money they save to set up small businesses such as poultry farming or beekeeping. “When women have their own income, they spend it on their families and the whole community benefits,” says Wadongo. Winning an international Seed award in 2011 helped the organisation to circulate lamps around the country – there are now more than 50,000 MwangaBora used in Kenya alone. Fundraising exhibitions featuring the lamps have taken place in New York and at the Pavilion of Art and Design in London, and Wadongo was named as one of CNN’s top 10 heroes in 2010. At the 2012 London Olympics, he was selected as one of four torchbearers for Kenya.

Despite these accolades, and donations from around the world, Wadongo says that financing the project is a challenge due to its long-term nature. Each lamp costs $25, which covers materials, training and distribution. The women’s groups can use money from their successful businesses to buy more lamps, creating a micro-finance system. “We want to make sure that in every community we get into, we leave them not only with lamps but with increased income levels,” he says.

The project has already taken off in Uganda and Wadongo is looking to further expansion. “We still have a whole lot of work to do in Kenya. By 2018, we want to be working in at least five countries in sub-Saharan Africa and have a million people benefiting from our program. Eventually we want to be able to do the same in South America, for example.”

And the impact could be global. Solar power saves lives by reducing the risk of fire caused by open flames and by improving villagers’ economic and educational prospects, but also by helping to save the planet, says Wadongo. “Burning one litre of kerosene produces 2.6kg of CO2, so with more than a billion people worldwide using it every day, you can imagine how much is emitted into the environment.”
