2. Renewable energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_energy

   Although almost all forms of renewable energy cause much fewer carbon emissions than fossil fuels, the term is not synonymous with low-carbon energy. Some non-renewable sources of energy, such as nuclear power, [contradictory] generate almost no emissions, while some renewable energy sources can be very carbon-intensive, such as the burning of ...

   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 ...

   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.

   Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's energy needs. 89 PW [32] of solar power falls on the planet's surface. While it is not possible to capture all, or even most, of this energy, capturing less than 0.02% would be enough to meet the current energy needs.

   Lifecycle surface power density includes land used by all supporting infrastructure, manufacturing, mining/harvesting and decommissioning. Another estimate puts the values at 0.08 W/m 2 for biomass, 0.14 W/m 2 for hydro, 1.84 W/m 2 for wind, and 6.63 W/m 2 for solar (median values, with none of the renewable sources exceeding 10 W/m 2).
