Natural gas is a gas produced by anaerobic decomposition of organic material. Usually found together with oil and natural gas deposits, but also generates swamps (in this case is also known as marsh gas) in landfill, and during digestion in animals.
The main difficulty in the use of natural gas transportation. The gas pipelines are economical, but not allow the crossing of oceans. Are also used for the carriage of liquefied natural gas, but have higher costs and security issues. In many cases, such as oil wells in Saudi Arabia, the natural gas that is recovered during the extraction of oil, can not be sold profitably, is burned on site. This wasteful practice is illegal in many states, because issues in Earth 's atmosphere greenhouse gases. Instead of being burned, the gas is re-injected into the ground waiting for a possible future extraction and to keep the pressure during the pumping of underground oil. Natural gas is often compressed for storage.
Natural gas is one of the main sources used for the production of electricity through the 'use of gas turbines and steam turbines.
The compressed natural gas (along with the LPG) is used as an alternative to other less polluting fuels for automobiles. Among the states with the highest number of gas vehicles are Argentina, Brazil, Pakistan, Italy, and India.
The largest producers of natural gas are Russia, Iran, the United States and Canada.
World reserves of natural gas at the end of 2003, amounted to about 154 trillion cubic meters. According to estimates, these reserves, if you will maintain current levels of consumption, should esauruirsi poor in about 70 years.
Other sources of natural gas, still experimental, which is extracted from the landfill gas methane, which is formed by the decomposition of waste, to provide electricity and heating to the city.
In Ontario and in Denmark in the project 'extraction of methane from manure produced by herds of animals (mainly pigs and cattle) to generate electricity, with one of these biogas plants are unable to produce enough electricity for a small town (2500 MW). This method can be further improved by adding other organic material such as an organic part of household waste. Description
