    [116] [117] Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL ), Japan ( NEDO ), and Germany ( Fraunhofer Institute for Solar Energy Systems ISE ).

    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.

    en.wikipedia.org/wiki/Renewable_energy

    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. Bioenergy and geothermal power are also significant in some countries.

    They replenish easily compared to non-renewable resources. The waters of the White Nile River are a key natural resource for Uganda. Non-renewable resources: These resources are formed over a long geological time period in the environment and cannot be renewed easily. Minerals are the most common resource included in this category.

    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 ]

    Renewable resources are available each year, unlike non-renewable resources, which are eventually depleted. A simple comparison is a coal mine and a forest. While the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. the coal mine, which once has been exhausted is gone.

    Renewable energy – energy which comes from natural resources which are naturally replenished. Natural resource – materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level).
