Ways to Reduce Air Pollution
How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are:
Riding a bike or walking instead of driving.
Taking a bus or carpooling.
Buying a car that has greater fuel efficiency.
Turning off lights and appliances when they are not in use.
Using energy efficient light bulbs and appliances.
Buying fewer things that are manufactured using fossil fuels.
All these actions reduce the amount of energy that power plants need to produce.
Developing alternative energy sources is important. Think back to the chapter, Earth’s Energy. What are some of the problems facing wider adoption of alternative energy sources?
The technologies for several sources of alternative energy, including solar and wind, are still being developed.
Solar and wind are still expensive relative to using fossil fuels. The technology needs to advance so that the price falls.
Some areas get low amounts of sunlight and are not suited for solar. Others do not have much wind. It is important that regions develop what best suits them. While the desert Southwest will need to develop solar, the Great Plains can use wind energy as its energy source. Perhaps some locations will rely on nuclear power plants, although current nuclear power plants have major problems with safety and waste disposal.
Sometimes technological approaches are what is needed.
