What’s all the hype?
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.

It makes us grow and move and think. Energy is the power to change things.
It is the ability to do work.

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?
Gather EvidencePresent evidence that a problem exists. Be
as specific as possible and cite at least one source of data:
Identify CausesBriefly list several underlying factors that
contribute to the problem that you have identified (support these factors with evidence):
Evaluate Policy1. 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?
SolutionsPropose 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.
