Natural gas Some of these gases include heptane, pentane, propane and other hydrocarbons with molecular weights above methane (). The natural gas transmission lines extend to the natural gas processing plant or unit which removes the higher molecular weighted hydrocarbons to produce natural gas with energy content between . The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in the transmission line to pressurize and re-pressurize the mid-stream natural gas as
Natural gas prices deal between the U.S. and Europe opens up access to cheap American natural gas, which allow Europe to diversify its supply base, but may threaten the Renewable Energy transition. Currently, Europe's main natural gas supplier is Russia. Major pipelines pass through Ukraine and there have been several disputes on the supply and transition prices between Ukraine and Russia. In September 2013, it was reported that multiple factors have conspired to cause Europe as a whole to decrease its use of natural gas and make more use of coal. The report also contains updated price trends. In South America, the second
