Rwanda has installed biogas plants in all 14 of its prisons, one small part of the central African nation’s plan to use renewable energy rather than the charcoal and firewood that provides 85 percent of its energy needs.

It plans to take biogas into Rwandan homes, where just 14 percent of the population currently has access to electricity, the Energy Ministry says.
