Renewable energy (also called green energy) is energy 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 .
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. [1] Renewable energy replaces conventional fuels in four distinct areas: electricity generation , air and water heating/cooling, motor fuels , and rural ...
Solar panels and wind turbines in Germany Placard for renewable energy, at the People's Climate March (2017) This is a list of renewable energy topics by country and territory. These links can be used to compare developments in renewable energy in different countries and territories and to help and encourage new writers to participate in ...
Renewable energy can be particularly suitable for developing countries. In rural and remote areas, transmission and distribution of energy generated from fossil fuels can be difficult and expensive. Producing renewable energy locally can offer a viable alternative. [9] Renewable energy doesn't always have to come from a developing country.
A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy. Renewable resource – natural resource with the ability to reproduce through ...
The United States has some of the best renewable energy resources in the world, with the potential to meet a rising and significant share of the nation's energy demand. A quarter of the country's land area has winds strong enough to generate electricity at the same price as natural gas and coal. [ 29 ]
Oceans often act as renewable resources. Sawmill near Fügen, Zillertal, Austria Global vegetation. A renewable resource (also known as a flow resource [note 1] [1]) is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale.
Geothermal energy is a renewable resource because thermal energy is constantly replenished from neighbouring hotter regions and the radioactive decay of naturally occurring isotopes. [90] On average, the greenhouse gas emissions of geothermal-based electricity are less than 5% that of coal-based electricity. [ 84 ]
