At the same time, in many African countries, solar power now stands to offer much more than environmental benefits. About 600 million Africans lack reliable access to electricity; in Nigeria specifically, almost half of the 230 million people have no access to electricity grids. Today, solar has become cheap and versatile enough to help bring affordable, reliable power to millions—creating a win-win for lives and livelihoods as well as the climate.
That’s why Nigeria is placing its bets on solar mini-grids—small installations that produce up to 10 megawatts of electricity, enough to power over 1,700 American homes—that can be set up anywhere. Crucially, the country has pioneered mini-grid development through smart policies to attract investment, setting an example for other African nations.
Nearly 120 mini-grids are now installed, powering roughly 50,000 households and reaching about 250,000 people. “Nigeria is actually like a poster child for mini-grid development across Africa,” says energy expert Rolake Akinkugbe-Filani, managing director of EnergyInc Advisors, an energy infrastructure consulting firm.
Though it will take more work—and funding—to expand mini-grids across the continent, Nigeria’s experience demonstrates that they could play a key role in weaning African communities off fossil-fuel-based power. But the people who live there are more concerned with another, immediate benefit: improving livelihoods. Affordable, reliable power from Mbiabet’s mini-grid has already supercharged local businesses, as it has in many places where nonprofits like Clean Technology Hub have supported mini-grid development, says Ifeoma Malo, the organization’s founder. “We’ve seen how that has completely transformed those communities.”
The African energy transition takes shape
Together, Africa’s countries account for less than 5 percent of global carbon dioxide emissions, and many experts, like Malo, take issue with the idea that they need to rapidly phase out fossil fuels; that task should be more urgent for the United States, China, India, the European countries and Russia, which create the bulk of emissions. Nevertheless, many African countries have set ambitious phase-out goals. Some have already turned to locally abundant renewable energy sources, like geothermal power from the Earth’s crust, which supplies nearly half of the electricity produced in Kenya, and hydropower, which creates more than 80 percent of the electricity in the Democratic Republic of Congo, Ethiopia and Uganda.
