context_page_description: Fossil fuel phase-out is the gradual reduction of the use of fossil fuels to zero use. Current efforts in fossil fuel phase-out involve replacing fossil fuels with alternative energy sources in sectors such as transport, heating and industry.
context_section_description: In 2015, hydroelectric energy generated 16.6% of the world's total electricity and 70% of all renewable electricity. In Europe and North America environmental concerns around land flooded by large reservoirs ended 30 years of dam construction in the 1990s. Since then large dams and reservoirs continue to be built in countries like China, Brazil and India. Run-of-the-river hydroelectricity and small hydro have become popular alternatives to conventional dams that may create reservoirs in environmentally sensitive areas.
