Sources of Air Pollution
• Most air pollution comes from burning fossil fuels– Coal– Oil– Natural Gas
The Biggest Sources: TransportationTransportation is the source of over 50% of our air pollution in the U.S.
The Biggest Sources: Electricity ProductionElectricity production is the source of about 20% of air pollution in the U.S.
Generating Electricity
Burning coal to generate electricity releases the most amount of air pollution.Coal is used to generate 45% of the electricity in the U.S.
How Coal is Used to Generate Electricity
Coal is burned to create heat, which is used to boil water and create steam. The steam then turns a turbine that rotates a generator that creates electricity.
