Non-renewable resource: Difference between revisions

Conversely, resources such as [[timber]] (when [[Sustainable forest management|harvested sustainably]]) and wind (used to power energy conversion systems) are considered [[renewable resource]]s, largely because their localized replenishment can also occur within time frames meaningful to humans ashuman welllifespans.

Natural resources such as [[coal]], [[petroleum]] (crude oil) and [[natural gas]] take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. Eventually itIt is consideredprojected that fossil-based resources will eventually become too costly to harvest and humanity will need to shift its reliance to other sources of[[renewable energy]] such as solar or wind power, see [[renewable energy]].

An alternative hypothesis is that carbon -based fuel is virtually inexhaustible in human terms, if one includes all sources of carbon-based energy such as methane hydrates on the sea floor, which are vastlymuch greater than all other carbon -based fossil fuel resources combined.<ref>{{cite web | url=http://worldoceanreview.com/en/wor-1/energy/methane-hydrates/ |title=Methane hydrates |website=Worldoceanreview.com |access-date=17 January 2017}}</ref> These sources of carbon are also considered non-renewable, although their rate of formation/replenishment on the sea floor is not known. However, their extraction at economically viable costs and rates has yet to be determined.

At present, the main energy source used by humans is non-renewable [[fossil fuels]]. Since the dawn of [[internal combustion engine]] technologies in the 19th century, petroleum and other fossil fuels have remained in continual demand. As a result, conventional [[infrastructure]] and [[transport]] systems, which are fitted to combustion engines, remain prominentpredominant throughoutaround the globe.

As of 2013 only a few kilograms (picture available) of uranium have been extracted from the ocean in [[pilot program]]s and it is also believed that the uranium extracted on an industrial scale from the seawater would constantly be replenished from uranium [[leaching (metallurgy)|leached]] from the ocean floor, maintaining the seawater concentration at a stable level.<ref name="gepr.org">{{Cite web|url=http://www.gepr.org/en/contents/20130729-01/|title=The current state of promising research into extraction of uranium from seawater – Utilization of Japan's plentiful seas : Global Energy Policy Research|website=gepr.org}}</ref> In 2014, with the advances made in the efficiency of seawater uranium extraction, a paper in the journal of ''Marine Science & Engineering'' suggests that with, light water reactors as its target, the process would be [[economy of scale|economically competitive if implemented on a large scale]].<ref>{{Cite journal|title=Development of a Kelp-Type Structure Module in a Coastal Ocean Model to Assess the Hydrodynamic Impact of Seawater Uranium Extraction Technology|first1=Gary|last1=Gill|first2=Wen|last2=Long|first3=Tarang|last3=Khangaonkar|first4=Taiping|last4=Wang|date=22 March 2014|journal=Journal of Marine Science and Engineering|volume=2|issue=1|pages=81–92|doi=10.3390/jmse2010081|doi-access=free}}</ref>

The potential wave [[energy]] on coastlines can provide 1/5 of world demand. Hydroelectric power can supply 1/3 of our total energy global needs. Geothermal energy can provide 1.5 more times the energy we need. There is enough wind to power the planet 30 times over, wind power could power all of humanity's needs alone30 times over. Solar currently supplies only 0.1% of our world energy needs, but there is enough out there tocould power humanity's needs 4,000 times over, the entire global projected energy demand by 2050.<ref>R.

Renewable energy and [[Energy conservation|energy efficiency]] are no longer niche [[Economic sector|sector]]s that are promoted only by governments and environmentalists. The increasing levels of investment and that more of the capital is from conventional financial actors, both suggest that [[sustainable energy]] has become mainstream and the future of energy production, as non-renewable resources decline. This is reinforced by [[climate change]] concerns, nuclear dangers and accumulating radioactive waste, [[2000s energy crisis|high oil prices]], [[peak oil]] and increasing government support for renewable energy. These factors are [[renewable energy commercialization|commercializing renewable energy]], enlarging the market and growing demand,increasing the adoption of new products to replace obsolete technology and the conversion of existing infrastructure to a renewable standard.<ref>{{cite web|url= http://energy-base.org/wp-content/uploads/2013/11/SEFI-Global-Trends-in-Sustainable-Energy-Investment-2007.pdf |title=Global Trends in Sustainable Energy Investment 2007: Analysis of Trends and Issues in the Financing of Renewable Energy and Energy Efficiency in OECD and Developing Countries (PDF), p. 3. |publisher=United Nations Environment Programme |access-date=2014-03-04}}</ref>

In economics, a non-renewable resource is defined as [[Good (economics)|goods]], wherewhose greater consumption today implies less consumption tomorrow.<ref>Cremer and Salehi-Isfahani 1991:18</ref> [[David Ricardo]] in his early works analysed the pricing of exhaustible resources, where heand argued that the price of a mineral resource should increase over time. He argued that the spot price is always determined by the mine with the highest cost of extraction, and mine owners with lower extraction costs benefit from a differential rent. The first model is defined by [[Hotelling's rule]], which is a 1931 economic model of non-renewable [[resource management]] by [[Harold Hotelling]]. It shows that efficient exploitation of a nonrenewable and nonaugmentable resource would, under otherwise stable conditions, lead to a [[resource depletion|depletion]] of the resource. The rule states that this would lead to a net price or "[[Hotelling rent]]" for it that roserises annually at a rate equal to the [[rate of interest]], reflecting the increasing scarcity of the resources.<ref>{{cite journal |first=H. |last=Hotelling |year=1931 |title=The Economics of Exhaustible Resources |journal=[[Journal of Political Economy|J.
