In the con­text of the civ­il war with no end in sight in South Sudan, this report out­lines how a donor-led shift from the cur­rent total reliance on diesel to renew­able ener­gy can deliv­er short-term human­i­tar­i­an cost sav­ings while cre­at­ing a longer- term build­ing block for peace in the form of a clean ener­gy infra­struc­ture. The report is sup­port­ed by the Africa pro­gram at the Unit­ed States Insti­tute of Peace.
