In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power. Percentages of various types of sources in the top renewable energy-producing countries across each geographical region in 2023. Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years. [3]
Renewable electricity generation by source and country in 2023 [1] This is a list of countries and dependencies by electricity generation from renewable sources. [1] Renewables accounted for 30% of electric generation in 2023. Renewables consist of hydro (47%), wind (26%), solar (18%), biomass (8%) and geothermal (1%).

This timeline of sustainable energy research from 2020 to the present documents research and development in renewable energy, solar energy, and nuclear energy, particularly regarding energy production that is sustainable within the Earth system. Renewable energy capacity has steadily grown, led by solar photovoltaic power. [1]
Size comparison of modern wind turbines Wind energy generation by region. As the 21st century began, fossil fuel was still relatively cheap, but rising concerns over energy security, global warming, and eventual fossil fuel depletion led to an expansion of interest in all available forms of renewable energy. The fledgling commercial wind power ...
At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. While many renewable energy projects are large-scale, renewable technologies are also suited ...
In 1802 lectures to the Royal Society, Thomas Young was the first to use the term energy to refer to kinetic energy in its modern sense, instead of vis viva. [3] In the 1807 publication of those lectures, he wrote, The product of the mass of a body into the square of its velocity may properly be termed its energy. [4]
This article lists the largest power stations in the world, the ten overall and the five of each type, in terms of installed electrical capacity. Non-renewable power stations are those that run on coal , fuel oils , nuclear fuel , natural gas , oil shale and peat , while renewable power stations run on fuel sources such as biomass , geothermal ...
