  1. Energy:Renewable vs. Nonrenewable What’s all the hype? Margaret Webster mmwebster@aol.com 8th Grade Science Ditmas, I.S. 62 Brooklyn, NY PS 4.1a,b: Describe the sources and identify the transformations of energy observed in everyday life. 4.1a The Sun is a major source of energy for Earth. Other sources of energy include nuclear and geothermal energy. 4.1b Fossil fuels contain stored solar energy and are considered nonrenewable resources. They are a major source of energy in the United States. Solar energy, wind, moving water, and biomass are some examples of renewable energy resources.

  2. What is Energy? • Energy helps us do things. It gives us light. It warms our bodies and homes. It bakes cakes and keeps milk cold. It runs our TVs and our cars. • It makes us grow and move and think. Energy is the power to change things. • It is the ability to do work. http://news.iworld.ua/category/hardware

  3. States of Energy Potential Energy Kinetic Energy • Resting or Stored Energy • Working or Moving Energy http://sjgsphysics.blogspot.com/2012/01/physics-1a.html

  4. Forms of Energy http://www.inspiration.com/global/i9ie-science-examples

  5. What is Renewable Energy? An energy resource that is replaced quickly. • Solar • Wind • Water • Geothermal • Biomass http://harmonscience6.wikispaces.com/Renewable+and+Nonrenewable+Resources

  6. What is Nonrenewable Energy? An energy source that takes millions of years to be created. • Oil • Natural Gas • Nuclear • Oil

  7. What is the problem? • The Public Policy Analysis (PPA) http://jdm-digital.com/2012/01/daydream-away/

  8. What is the Evidence?

  9. What is the Evidence?

  10. What is the Problem? • Why has energy consumption increased over the last decade? • Why are renewable resources used more in the United states? • Why is the United States looking for energy alternatives to nonrenewable energy?

  11. Gather Evidence • Present evidence that a problem exists. Be as specific as possible and cite at least one source of data:

  12. Identify Causes • Briefly list several underlying factors that contribute to the problem that you have identified (support these factors with evidence):

  13. Evaluate Policy • 1. State one of the major existing policies that attempts to deal with the social problem: • 2. What are the advantages of this policy (consider effectiveness, costs, enforcement, and public acceptance): • 3. What are the disadvantages of this policy? Consider effectiveness, costs, enforcement, and public acceptance): • 4. Based on your evaluation of the advantages and disadvantages, should the current policy be totally replaced, strengthened, or improved? What advantages, if any, from the current policy should be retained? What disadvantages, if any, should be eliminated?

  14. Solutions • Propose at least three new/original public policy alternatives. Be sure that all of your public policy alternatives are at the same geopolitical level as your social problem. Each alternative must specify the actual government or government agency that will carry out the proposed action. List the proposal that your group considers the most promising first.

  15. Resources • Government Energy Source
