Solar energyThe DRC is in a very high level sun belt, with insolation values of between 3.25 and 6.0 kWh/m2/day. This makes installation of photovoltaic systems, as well as use of thermal solar systems, viable throughout the DRC. Currently there are 836 solar systems, with a total power of 83 kW, located in: Equateur (167), Katanga (159), Nord-Kivu (170), the two Kasaï provinces (170), and Bas-Congo (170). There is also the 148 Caritas network system, with a total power of 6.31 kW.Wind energyIn some areas, wind speed is equal to or greater than 1.4 m/s, (1.5 m/s at Matadi, 1.7 m/s at à Gimbi and 1.8 m/s at Kalemie and Goma). However, wind energy is not used in DRC, with the exception of a few pilot facilities, or in isolated cases where the energy is used to supply pumps and lighting. One particular hotspot in the country has been identified, at Ugoma, where wind speeds are in the 6-6.6 m/s range. Due to the country’s vast land area, an estimated total potential for wind energy of 77,380 MW, or 102 TWh exists. However, it is unclear what proportion of this potential is deemed economically feasible.Biomass energyIn terms of tranditional fuel woods, the DRC has around 125 million hectares of forest, with the wood potential estimated at 12.5 billion m3 i.e., 100 m3 of wood per hectare, and annual production is 2 m3/ha. Firewood and charcoal account for the majority of primary energy consumption. However, these fuels waste limited local wood resources, as well as generating considerable pollutants that affect users' health.Biogas production from plant and animal wastes also holds a significant potential in the DRC. Barriers to development are:-the high cost of digesters in relation to average incomes,-the lack of training of users and maintenance staff.There are estimated methane reserves of 50 billion m3 at Lake Kivu, which have been investigated for exploitation by numerous parties.BiofuelsThe country’s potential for biofuel production is vast. However, experiments at the Kiliba molasses distillery suffered the effects of the war. The work has stopped, and there is no indication of it recommencing.Geothermal energyThere is huge geothermal potential in the east of DRC consisting of volcanoes and active geothermal sites, but this is hardly exploited. Hot spring temperatures range from 35 to 90ºC, with flow rate averages ranging from 11 to 162 litres/sec.HydropowerDRC has large hydroelectric resources, estimated at 774 GWh, i.e. 66% of central Africa's potential, 35% of the continent's potential and 8% of world annual potential. This corresponds to a minimum exploitable power capacity of 88,400 MW. A truly vast potential exists for development of further hydroelectric resources, and estimates put potential hydropower export capacity at 51.9 TWh/year, which would create revenues for the country of over 6% of current GDP.
