[6] The only refinery in the country, managed by the Tunisian Company of Refining Industries, is located in Bizerte.[8] In return for the crossing of its territory, Tunisia is entitled to 5.625% of the gas, in kind or in money, in accordance with a treaty of 1977.Virtually all Tunisian electricity (18 TWh) is produced by thermal power plants burning natural gas, the largest of which is in Sousse.Wind energy is the second largest source of electricity in the country; a capacity of 305 MW has been installed in a few years.STEG has been subsidizing consumer electricity prices since 2004 (due to 2000s energy crisis and weak national currency).The British company TuNur Ltd proposed a major project in solar energy in 2010s, which would consist in building in stages 4,500 MW of thermodynamic solar power plants in southern Tunisia, and export electricity to Malta first, then Italy and finally France.In addition to wind and hydro, the Tunisian government plans to use biogas to produce renewable energy.[13] In 2016, Tunisia emitted 29 Mega tons of carbon dioxide equivalent (MtCO₂e) in greenhouse gasses.These organizations would be able to function through schools to teach students about renewable energies resulting in their widespread adoption in the future.
