What is the problem? The Public Policy Analysis (PPA)

What is the Evidence?

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

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

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?

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.
