Portal:Renewable energy - Wikipedia

Renewable energy (also called green energy) is energy made from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial, as nuclear energy requires mining uranium, a nonrenewable resource. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power. Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years. A large majority of worldwide newly installed electricity capacity is now renewable. Renewable energy sources, such as solar and wind power, have seen significant cost reductions over the past decade, making them more competitive with traditional fossil fuels. In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity. From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Power from the sun and wind accounted for most of this increase, growing from a combined 2% to 10%. Use of fossil energy shrank from 68% to 62%. In 2024, renewables accounted for over 30% of global electricity generation and are projected to reach over 45% by 2030. Many countries already have renewables contributing more than 20% of their total energy supply, with some generating over half or even all their electricity from renewable sources.

The main motivation to use renewable energy instead of fossil fuels is to slow and eventually stop climate change, which is mostly caused by their greenhouse gas emissions. In general, renewable energy sources pollute much less than fossil fuels. The International Energy Agency estimates that to achieve net zero emissions by 2050, 90% of global electricity will need to be generated by renewables. Renewables also cause much less air pollution than fossil fuels, improving public health, and are less noisy.

The deployment of renewable energy still faces obstacles, especially fossil fuel subsidies, lobbying by incumbent power providers, and local opposition to the use of land for renewable installations. Like all mining, the extraction of minerals required for many renewable energy technologies also results in environmental damage. In addition, although most renewable energy sources are sustainable, some are not. (Full article...)

Brookfield Renewable Partners L.P. is a publicly traded limited partnership that owns and operates renewable power assets, with corporate headquarters in Toronto, Ontario, Canada. It is 60% owned by Brookfield Asset Management.

As of the end of 2017, Brookfield Renewable owned over 200 hydroelectric plants, 100 wind farms, over 550 solar facilities, and four storage facilities, with approximately 16,400 MW of installed capacity.

Brookfield Asset Management claims to have "more than 100 years of experience as an owner, operator and developer of hydroelectric power facilities." It was founded in the 1890s in Brazil, where the company installed the first electrical lights and tramways in São Paulo and Rio de Janeiro. (Full article...)

Denis Allen Hayes (born August 29, 1944) is an environmental advocate and an advocate for solar power. He rose to prominence in 1970 as the coordinator for the first Earth Day.

Hayes founded the Earth Day Network and expanded it to more than 180 nations. During the Carter administration, Hayes became head of the Solar Energy Research Institute (now known as the National Renewable Energy Laboratory), but left this position when the Reagan administration cut funding for the program.

... that Selling Solar: The Diffusion of Renewable Energy in Emerging Markets, a 2009 Earthscan book by Damian Miller, argues that in order to solve the climate crisis, the world must immediately and dramatically accelerate the commercialization of renewable energy technology ? This needs to happen in the industrialized world, as well as in the emerging markets of the developing world where most future GHG emissions will occur.
