Inadequate and expensive electricity supply constitutes a limiting factor to development. Wood is the main source of energy for 86.3% (2010) of the population down from 99% in 2000 which is a significant drop. This leads to massive deforestation and soil destruction. Imported petroleum products consume more than 17% of foreign exchange. Rwanda will therefore increase energy production and diversify into alternative energy sources. To achieve this, Rwanda has considerable hydroelectric potential, in addition to large deposits of renewable methane gas in Lake Kivu, estimated at 60 billion cubic meters. In rural areas direct solar energy or photovoltaic energy can be used, whilst up to 1/3 of 155 million tons of peat deposit is currently exploitable. Rwanda projects that by 2020, at least 75% of the population will be connected to electricity (up from 2% in 2000 and 11% in 2010) and the consumption of wood will decrease from the current 86.3% to 50% of national energy consumption.
