Report: For Developing Countries, More Solar Power — and Maybe More Lead?

Undark discusses how, for developing countries, more solar power might mean more lead. In developing nations like India, solar power’s reliance on lead batteries could have a big impact on some communities.

The situation is similar across the developing world. In sub-Saharan Africa, some 600 million people still lack access to electricity. In areas where grid connectivity is infeasible, microgrids that rely on solar or other types of renewable energy may offer solutions. According to a report by the United States Agency for International Development and the Department of Energy’s National Renewable Energy Laboratory, “the vast majority of batteries in micro-grid applications worldwide have been lead-acid” to date. In Kenya, where the government is aiming to provide electricity to all residents by 2022, off-grid systems play an important role. And according to a draft report prepared for the country’s Energy Regulatory Commission, lead-acid batteries are the main form of energy storage available on the market.
