Title: Fossil fuels are energy resources made from carbon-rich plant and animal remains.


1
Fossil Fuels
  • Fossil fuels are energy resources made from
    carbon-rich plant and animal remains.

US Consumption
(mixed with natural gas and petroleum)
Total 83.2
2
Raw fossil fuels are obtained by drilling or
mining.
  • Coal is a sedimentary rock formed from the
    remains of dead plants at the bottom of ancient
    swamps.
  • Coal mining can involve removing soil and rocks
    or creating deep mines.

3
  • Petroleum means rock oil. It formed from the
    remains of single-celled aquatic organisms that
    lived long ago.
  • Natural gas and petroleum are formed from buried
    organic matter. Methane is the main component of
    natural gas.
  • Some fossil fuels are gases that became trapped
    in rock formations.

4
  • Fossil fuels are nonrenewable because they take
    millions of years to form.

5
Uses
  • After petroleum is mined, it is separated into
    fuels such as gasoline, diesel, and jet fuel.
  • Natural Gas is used for heating homes, schools,
    and businesses. It is also used for electricity.
  • Coal is used for electricity and manufacturing.

6
Benefits
  • Economic Coal is mined in 25 states. People
    make money by mining and selling it.
  • Environmental Natural gas burns more cleanly
    than other fossil fuels.
  • Physical We already have processes in place and
    power plants set up to use fossil fuels.

7
Drawbacks
  • Environmental Burning fossil fuels produces
    carbon dioxide, a greenhouse gas, as well as
    harmful acids and other forms of pollution.
  • Physical Mining and drilling for fossil fuels
    can destroy landscapes and pollute water
    supplies. Transporting oil can result in spills
    that pollute the environment and harm wildlife.
  • Social People dont want to build near fossil
    fuel power plants.

Interesting facts At current usage, the coal
supply will last 1500 years. However at a 5
growth rate the coal supply will last only 86
years. We can expect even greater usage as other
fossil fuels become scarce. To run a 100-watt
light bulb 24 hours a day for a year we need to
use about 714 pounds (325 kg) of coal in coal
powered power plant The United States
uses about 17 million barrels of oil every day.
It takes the equivalent of 7 gallons of
gasoline per day for every man woman and child to
keep this country running at its current pace.
The U.S. is home to 5 of the world's
population, yet consumes 26 of the world's
energy.
