Question

a short note on conservation of non -renewable resouces in 100 - 150 words​

Answer 1

Answer:

Energy conservation is a very important part of energy planning and its management. It not only saves energy resources for future, avoids wasteful utilisation of energy, provides solution to energy crisis and ensures higher per capita availability/ consumption but controls environmental degrada­tion and pollution.

New strategy emphasies greater reliance on non-exhaustible and non-conventional sources of energy so as to conserve exhaustible conventional resources like coal, petroleum, natural gas etc. That is why efforts are being made to promote the development and use of non-conven­tional sources of energy. Another aspect of energy conservation is related to the reduction in consump­tion of energy.

This can be achieved by change in the individual habits, utilising latest technology, reduce the subsidy and increase the price of the energy. For example, a lot of electricity can be saved by using energy efficient lamps. The Superglue gives 20 per cent more light and saves up to 10 per cent energy.

Answer 2

A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption.[1] An example is carbon-based fossil fuel. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions).


A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.
Conversely, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can occur within time frames meaningful to humans as well.
