What is a major disadvantage of using nuclear power to generate electricity?

• A small amount of power is produced 
• No greenhouse gases are produced
• The power plants are inexpensive to build
• The by-product of nuclear power is radiation

Which of the following recommendations could a community make to its citizens that would do the most to conserve energy resources?

• Carpool, bicycle, or walk whenever possible

Why is it better to obtain energy from natural gas instead of coal and oil? Natural gas –

• produces fewer greenhouse gases. 
• is a renewable energy source.
• is not a natural resource.
• produces more toxic waste.

The advantage of burning coal in order to generate electricity is that coal is –

• an inexpensive source of energy.  
• the least energy efficient fossil fuel. 
• a non-polluting source of energy.
• a renewable energy source.

• Wood and coal are the heaviest of all the fuels 
• Oil produces less energy than propane or coal
• Propane is a more popular energy choice than wood 
• Natural gas produces less carbon dioxide than coal

• Turn off computers and other electronics when they are not in use
• Increase the temperature of a house in warm months, and decrease it in cool months
• Turn off lighting that is not necessary, or when the household is empty
• Keep the refrigerator door closed as much as possible to avoid letting cold air out

An advantage of burning coal to generate power for electricity is that coal is -

• relatively inexpensive to mine and transport.  
• available in a limited supply.
• found in few places in the United States.
• harmful for the environment.

• wind energy
• biomass
• natural gas
• solar energy
