The National Energy Policy (NEP) was updated in December 2015 by the Ministry of Energy and Minerals. It aims at sustainably providing adequate, reliable and affordable energy to the Tanzanians. The NEP notably aims at scaling up the utilisation of renewable energy per se and to diversify the country's energy mix, using solar, biomass, wind, small-scale hydro and geothermal, including in buildings and industrial designs. Feed-in tariffs should be established and renewable energy integrate both the national and isolated grids. Alternatives to wood for cooking are also promoted. Besides, the document calls for a controlled use of new petroleum discoveries in the country.
