As of 2016, about 12% of the population of Sierra Leone had access to electricity. Of the 12%, 10% was in the capital Freetown, and the remaining 90% of the country used 2% of the nation's electricity. The majority of the population relies on biomass fuels for their daily survival, with firewood and coal used most prevalently. The burning of these sources has been reported to have adverse health effects on women and children. A 2012 study was done on the correlation between Acute Respiratory Infection (ARI), and burning biomass fuels in the home. The results were that 64% of children were diagnosed with ARI where firewood stoves were used, and 44% where charcoal stoves were used. The use of coal and firewood has also posed environmental concerns as they are both in conflict with the push for more sustainable sources of energy. As a result, the commercialisation of firewood and coal has been a point of contention with aid donors and government agencies such as the Ministry of Energy and Water Resources and the Forestry Division. There have been strong pushes for both solar and hydropower to become the dominant sources of energy in Sierra Leone because of the UN's Sustainable Development Goals, particularly goal number seven (affordable and clean energy). Sierra Leone's tropical climate, heavy annual rainfall, and abundance of rivers give it the potential to realistically pursue more solar and hydropower alternatives.
