1.a.What two forms of energy does the sun supply?
1.b. What are two reasons that solar energy has not replaced energy from fossil fuels?
1.c. A friend of yours argues that shoping malls should use solar energy to conserve fossil fuesl. How would you respond?
2.a. List five renewable energy sources other than solar energy.
2.b. Which one of the renewable energy sources that you listed are actually indirect forms of solar energy? Explain.
2.c. Which source of renewable energy do you think is most likely to be used in your community in fifty years? Give reasons to support your answers.
Writing In Science
Write an advertisement for one of the renewable energy sources dicussed in this section. Be sure to mention how its advantages make it superior to the other energy sources. Also mention how might be able to overcome these disadvantages.
btw u dont have to answer them all these are just a few i could never answer.
