Haiti has limited energy resources: no petroleum or gas resources, small hydroelectricity potential and rapidly declining supplies of wood fuels. With very limited access to electricity, most of the population in Haiti depends on charcoal as a source of energy. The National Electricity Company (Electricité d'Haïti – EDH) was created in 1971 to operate the newly built hydroelectric plant and the nation's power system. Electricity consumption increased sixfol.
