Sector Briefings

Concise essays that explain how subsidies feature in five economic sectors, and the implications for sustainable development.

  • Energy

    The energy sector comprises the production, sale and distribution of energy, including fuel extraction, manufacturing, refining, transformation and transportation. Fossil fuels – oil, natural gas and coal – are the leading primary sources of energy. Other sources are nuclear energy, traditional biomass fuels, such as firewood and charcoal, and renewables, including hydroelectric, geothermal, wind and solar power. Primary fuels can be converted into final forms or carriers of energy, such as refined oil products, electricity and hydrogen, or used directly in final uses.
