In the Democratic Republic of the Congo, there are both coal and crude oil resources that were mainly used domestically in 2008. The Democratic Republic of Congo has the infrastructure for hydro-electricity from the Congo River at the Inga dams. The Democratic Republic of Congo also possesses 50% of Africa's forests and a river system that could provide hydro-electric power to the entire continent, according to a UN report on the country's strategic significance and its potential role as an economic power in central Africa.
