In the past decade there has been increasing concern about the impact of the use of fossil fuel on environmental air quality and climate.  This paper will explore the current national and state legislative attempts to encourage the homeowner to embrace various activities to reduce fossil fuel usage in the homestead.  Since federal tax subsidies for residential wind and fuel cells end at the end of 2016, the paper will focus upon the remaining solar voltaic and solar hot water subsidies and calculate the present value benefit per average solar hour of the federal tax subsidies and different state regulatory efforts relating to solar.  This study will also explore the cost/benefit in various states of the state and federal incentives along with a critical analysis of the assumptions behind the analysis.
