To accommodate mines and associated infrastructure, land is cleared extensively, consuming significant energy and water resources, emitting air pollutants, and producing hazardous waste. [4] According to The World Counts page "The amount of resources mined from Earth is up from 39.3 billion tons in 2002. A 55 percent increase in less than 20 years.
In 2009, a simplified United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources 2009 (UNFC-2009) was published. [8] In response to the application of UNFC being extended to renewable energy, injection projects for geological storage and anthropogenic resources, the name was changed in 2017 to the United ...
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]
