Resources and technology do not constrain the capacity of nuclear power to contribute to meeting the energy demand for the 21st century. However, political and environmental concerns about nuclear safety and radioactive waste started to limit the growth of this energy supply at the end of last century, particularly due to a number of nuclear ...

India imports small amounts of natural gas. In 2004, India consumed about 1,089 × 10 ^ 9 cu ft (3.08 × 10 10 m 3) of natural gas, the first year in which the country showed net natural gas imports. During 2004, India imported 93 × 10 ^ 9 cu ft (2.6 × 10 9 m 3) of liquefied natural gas (LNG) from Qatar. [16]
Mineral classification schemes and their definitions are evolving to match recent advances in mineral science. Recent changes have included the addition of an organic class, in both the new Dana and the Strunz classification schemes. [152] [153] The organic class includes a very rare group of minerals with hydrocarbons. The IMA Commission on ...
A natural resource may exist as a separate entity such as freshwater, air, or any living organism such as a fish, or it may be transformed by extractivist industries into an economically useful form that must be processed to obtain the resource such as metal ores, rare-earth elements, petroleum, timber and most forms of energy. Some resources ...
