Review of State and National Renewable Energy Policies

There is a growing importance for improving renewable energy policies especially in the United States to achieve a goal of 20% or more of nation´s electricity from wind energy by 2030. Governments at various local, state and federal levels often revise the policy design and implementation to encourage renewable electricity generation. This paper illustrates some of the renewable energy policies (especially wind) of Texas at state level and United States at federal level and also discusses issues within those policies. Special focus is put on the following topics: Renewable portfolio standards, Production Tax credits, Feed-in tariffs and Net-metering.
