Africa's Energy Surge

Today, there are 1.1 billion people worldwide who still have little or no access to electricity. Over half of them live in sub-Saharan Africa. And more than 80% of those living in that region still do not have access to clean cooking. But Africa is poised to become a huge part of the clean energy solution. Rachel Kyte - CEO and Special Representative of the UN Secretary-General for Sustainable Energy for All - talks to CNN about the plan to close the energy access gap in Africa - and around the world - and how we can get it done well before 2030.
