In the report, the IPCC said "as infrastructure and energy systems develop, in spite of the complexities, there are few, if any, fundamental technological limits to integrating a portfolio of renewable energy technologies to meet a majority share of total energy demand in locations where suitable renewable resources exist or can be supplied".

In 2005, economic losses (mainly from air pollution) were calculated at 7.7% of China's GDP. This grew to 10.3% by 2002 and the economic loss from water pollution (6.1%) began to exceed that caused by air pollution. [18] China has been one of the top performing countries in terms of GDP growth (9.64% in the past ten years). [18]
Green energy is an alternative to using fossil fuels. Some examples are solar energy, wind energy, and nuclear energy. These alternatives use natural energy instead of fossil fuels to promote green electricity. The use of green energy can boost any economy, for example in India it could create a green energy market worth 80 billion by 2030. [18]
Energy storage helps overcome barriers to intermittent renewable energy. [70] The most commonly used and available storage method is pumped-storage hydroelectricity. This requires locations with large differences in height and access to water. [70] Batteries are also in wide use. [71] They typically store electricity for short periods. [72]
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.
Nuclear energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [42] There is a catastrophic risk potential if containment fails, [43] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
