The other day we ran across a map by the US Energy Information Administration documenting the number of states that had passed enforceable Renewable Portfolio Standards (RPS). These resources include wind, solar, geothermal, biomass, and some types of hydroelectricity, but may include other resources such as landfill gas, municipal solid waste, and tidal energy on the state level. In most cases, the states have specific 10-15 year goals to increase their renewable energy usage to 20-25 percent by 2020 or 2025. California, for example, has an ambitious goal to have 33% of its energy portfolio coming from renewables by 2020.
Although no national RPS law has been enacted, surprisingly, 30 states and the District of Columbia have adopted mandatory and enforceable Renewable Portfolio Standards and 7 states have adopted voluntary policies.
What is striking about these new state renewable policies is their coverage – almost 4 out of 5 states have RPS including the largest states in population (California, Texas and New York).
The second most interesting element on the map is the lack of state-adopted policies in the Deep South.
It does look like, Alabama, Mississippi, Georgia, Florida, Louisiana, Arkansas, South Carolina and Tennessee have some “catching up” to do when it comes to renewable energy standards.
