Transcript of Fossil Fuels

Fossil Fuels What is a Fossil Fuel? What is a fossil fuel? What are the three major fossil fuels? When animals and other organisms die, their remains pile up and become buried. Over millions of years, heat and pressure change the remains into energy-rich fossil fuels we use daily. The three major fossil fuels are coal, oil, and natural gas. By Sanjana Duvvuri And Xan Denker The Uses of Fossil Fuels Coal is used to generate half of all the electricity in the U.S. We Use oil to power our cars and other automobiles. Natural Gas powers millions of peoples' homes across the country. Check out at this video about the history of fossil fuels: Why are fossil fuels non-renewable resources? The formation process of fossil fuels takes millions of years, so fossil fuels are considered non-renewable resources. A piece of coal takes
at least 440 MILLION years
to form! Crude oil is the yellowish-blackish oil that has not been refined. Crude oil is also known as petroleum. Currently, renewable and clean energies like hydroelectric, solar power, and wind power only make up about 6% of the Nation's energy. At the current rate we are burning up coal, the supply will last about 1500 years. If the usage rate increases by 5%, the supply will only last 86 years. 1 liter of gasoline is approximately equal to 23.3 tons of organinc materials that were changed into fossil fuels.

The Advantages and Disadvantages of Fossil Fuels COAL Advantages Coal is the most abundant fuel.
It is very easy to transport.
It provides a lot of energy when burned. Disadvantages Coal mining is very dangerous.
Burning coal pollutes the air with greenhouse gases.
Runoff from coal mines can create water pollution. OIL Advantages Oil is cleaner than coal when burned.
The energy that oil yields is very reliable.
Without oil, whales would most likely be extinct. Before oil was discoverd, the primary source of fuel for lamps was whale blubber! http://fossil-fuel.co.uk/oil/the-advantages-of-oil Disadvantages Oil, like all fossil fuels, pollutes the air and, in cases of massive oil spills, the water.
The majority of the oil in the world is located in politically unstable areas.
The increasing consumption and decreasing production of oil has driven the cost up. NATURAL GAS Advantages It produces a low amount of pollution.
Natural Gas is very efficient in producing energy.
It is easy to transport and store. Disadvantages It is highly flammable.
If a leak occurs, you will most likely not notice because it is odorless and colorless.
Greenhouse gas pollution occurs when burned. http://www.ehow.com/list_6579640_advantages-over-other-energy-sources.html http://www.tc.umn.edu/~dama0023/naturalgas.html Hydrocarbons Hydrocarbons are the chemical compounds inside fossil fuels. They are made of hydrogen and carbon, and produce heat and light energy when burned. Petrochemicals Petrochemicals are the products of petroleum, or crude oil. Petrochemicals include things such as paints, plastics, cosmetics and some medicine.
