Renewable energy (or 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. Bioenergy and geothermal power are also significant in some countries.
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. Renewable energy replaces conventional fuels in four distinct areas: electricity generation , hot water / space heating , motor fuels , and rural (off-grid ...
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.

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.
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.

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.
