Energy generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. 

Inexhaustible resources are resources that are present with unlimited amounts in the nature; they cannot be depleted or exhausted by human activity. Inexhaustible resource is known as a renewable resource. This includes water, sand clay, water as well as solar energy.

A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all non-renewable resources.

The resources which are available in nature in an unlimited amount, known as inexhaustible resources. These resources can be replenished again and again for use. The light energy is inexhaustible resources which are obtained from the sun. The wind and light energy can be used for the generation of electricity. The sand is available in large amounts and is used for the production of glass. 

A non-renewable resource (also called as a finite resource or depleting source) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) are all non-renewable resources. In contrast, resources such as sunlight, water, timber and wind are considered renewable resources, largely because their localized replenishment can occur within time frames useful to humans.

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. The trees can be replenished by afforestation method in which new trees can be planted. The agricultural products can be obtained again when the new crops are produced in the farm. The wildlife species once extinct cannot be replenished again. 

The Department of Non-Conventional Energy Sources (DNES) was a new department which was set up in the ministry of energy. The establishment of this department took place in the year of 1982. Later on, the department was transformed into the ministry of non-conventional energy resource. 

The resources which can be replenished again after their consumption are referred as the renewable sources of energy. Water resource can be replenished due to rainfall. Soil production occurs due to the breaking of the rocks. The forests can be replenished through afforestation.

The minerals are obtained from the ores through mining. There are limited resources of the minerals present in the Earth's crust. Lead is used in the making of the batteries of the electronic devices. Gold is known for its commercial value in the making of the jewellery. Tin is used for various purposes from the ancient age. Tin was used for the making of coin, utensils, alloy making, etc. Tin is now commonly used for the preparation of the jars. The exploitation of these metals has resulted in fewer resources left and so, the metal resources will be exhausted first.

The resources which cannot be replenished again after consumption of resources are known as non-renewable resources. Minerals are obtained from the ores and they are available in limited forms. The metals are obtained through mining and are present in reserved amounts in the Earth's crust. The fossil fuels are synthesized due to the decomposition of the dead matter for long period of time. These resources cannot be replenished once they are used up.
