what is fossil fuel
What is Fossil Fuel?
  • Microorganisms are buried and decay
  • Formed millions to hundreds of millions of years ago
  • Supply is limited
  • Burning produces carbon dioxide (CO2)
  • Contains other impurities that cause pollution
examples of fossil fuels
Examples of Fossil Fuels:

Extreme emissions and pollution

  • Petroleum (oil)
    • Used to fuel vehicles
  • Coal
    • Powers electricity plants
more examples
More examples:

Fossil Fuels considered to be less harmful than oil…. But still limited in supply.

  • Natural Gas
  • Propane
    • Domestically abundant (in the USA)

Fossil Fuel Dependence

alternative sources of energy
Alternative Sources of Energy
  • Options to replace fossil fuels
  • Solutions to solve environmental problems
    • Reduce carbon emissions
    • Lowers other greenhouse gases
biomass energy sources
Biomass energy sources
  • Ethanol
    • Produced domestically
    • From corn or other crops
    • Produces lower greenhouse emissions
  • Biodiesel
    • From vegetable or animal fats
    • Produces less pollution

Alternative Fuels

electricity as an alternative
Electric Motor Vehicles

75% of energy is converted to power

No tailpipe emissions

Domestic (self reliant)

Stronger acceleration

Less maintenance

Electric Cars

Internal Combustion Engine

15-20% of energy is converted to power

Great emissions

Political and Economic issues

Electricity as an Alternative
