Transcript of Natural gas

Natural gas
By Ralitsa Galabova and Dorian Kupper
-Non renewable resource
-combustible mix of hydrocarbon gases.
-Formed mainly of methane, and also other alkanes.
-Found in reservoirs under the Earth.
-Formed when organic matter is compressed under the Earth at very high pressure, high temperature, for a very long period of time.
-Refined to remove impurities.
-Transmitted through a network of pipelines.
-reduces pollution, and maintains a clean and healthy environment.
Global production of natural gas per country

-Cleanest of all the fossil fuels.
-Small amounts of sulfur dioxide
and nitrogen oxides, no ash and lower
levels of carbon dioxide, carbon monoxide
and other reactive hydrocarbons.
-Fewer harmful pollutants.
-Does not contribute significantly to smog
formation and acid rain.
-Used to improve air quality.
-Fuel for vehicles.
-Still contributes to pollution and the
emission of greenhouse gases.
-Odourless and colourless, difficult
to detect.
-Danger of leaking, spillage and
-A lot of land has to be cleared to
drill, causes deforestation.
-Increased government revenues
-20 to 30 % cheaper than gasoline
-less than 50 % of the price of a barrel of oil
-costs mainly on transport infrastructure

-Pipelines very expensive to build.
-Depend on international price changes
-Subject to economic, political and military pressure.
-Reserves will last only 50-70 years.
-High costs of drilling.
-Difficult to discover and exploit.
-Provides less mileage than gasoline.
-Prices vary a lot between continents.
-Every 1% increase in production of natural gas creates up to 35000 jobs.
-Can be used for different tasks: cooking, heating, generating electric power...

-Most common cause of carbon monoxide deaths.
-Dangerous job (drilling).
In spite of some economic disadvantages and safety issues, overall natural gas is the best fossil fuel energy source from all aspects.
It does not contribute as much to pollution, global warming, acid rain. It creates more jobs. It is the cheapest fossil fuel with the highest energy efficiency (90%) and has a lot of domestic uses.
