The most common source of energy in rural areas of Africa is usually a kerosene lamp, which emits little light but a great deal of harmful smoke. Each lamp burns about 40 litres of kerosene per year, producing about 80 kg of CO2.
In addition, diesel generators are in use throughout Africa, often also used by international aid agencies for electricity supply. However, diesel generators are expensive to maintain and operate. In addition to CO2 emissions, improper disposal of the old oil and diesel is one of the biggest problems.
