Natural Resources Defence Council (NRDC), an environmental action group whose mission is to "safeguard the Earth", is hosting a nice online interactive map of renewable energy in the US. The map shows the country divided into states, color coded according to the kind of renewable energy being shown (blue tones for wind, red tones for solar, biogass brown, and cellulosic biomass green. Darker shades of each color tone represent areas that are richest with the corresponding type of renewable energy resources. For example, Arizona is a very dark red, signifying that solar projects in this area would enjoy the most sunlight, while Idaho has a nice big patch of dark blue, which means wind power projects would be a great option there. The map can show existing and/or planned facilities, depending on the user's choice.

Users can easily input basic location information such as zip code, and quickly be shown a corresponding zoomed area corresponding, usually a county within a state. Unforutunately, this is where the tool stops with information. So far, the map boils down to having a general overview of renewable energy resource availability in the US, down to the county level, but unfortunately it only covers wind, solar, biogas and biomass (where is hydro power or geothermal?). There are tables with values associated with different classes of renewable energy availability, although associated with numbers representing a class, rather than color coded, which can be somewhat confusing, but it is easy enough to get the idea of the available parameters for a certain area. It would maybe have been nicer to present the data on the areas themselves, rather than having to click and look at an overlaying layer showing the tables.
Sveral US states have been covered in more detail – Florida, Nebraska, Ohio, Pennsylvania and Tennessee. If you are wondering why these five particular states, NRDC points them out as the most promising states in terms of renewable energy infrastructure. Additional state profiles will be added over time.
