  • Solar panels transform energy from —
    electrical to radiant
    radiant to thermal
    thermal to electrical
    radiant to electrical
  • Why are fossil fuels nonrenewable?
    they take millions of years to form
    they cause pollution when burned
    they can easily be replaced by humans
    they burn up at a faster rate than renewable resources
  • Fossil Fuels, Renewable Resources, and Nonrenewable Resources are all--
    Resources That Generate Electricity
    Resources That are Running Out
    Human-made Resources
    Types of Pollution
  • Why do people need to find and use new forms of energy?
    Fossil fuels are unlimited.
    Fossil fuels no longer exist on Earth.
    Wind, solar, and water power are nonrenewable resources.
    Coal, oil, and natural gas are nonrenewable resources
  • What challenges might engineers face when designing ways to harness wind energy?
    Spinning turbine blades can be very noisy
    Some days are cloudy and there is no sunlight
    Some dams can harm the environment.
    Towers are cheaper than they were 25 years ago.
  • If you made a poster for green energy initiatives, which would you NOT put on it?
    Diesel cars are the ONLY way
    Say YES to paper straws
    NO DRAFTS! Replace old windows!
    Use more LED bulbs

    air pollution & energy loss
  • What can you do to reduce your home electric bill?
    Take longer showers instead of baths.
    Leave lights on in a bright, sunny room.
    Unplug appliances when they are not in use.
  • What can you do to reduce your home electric bill?
    Take longer showers instead of baths.
    Dry clothes on an outside clothesline.
    Use cloth napkins instead of paper napkins.
  • Which energy source would decrease in power during a drought?
