Most troubling are the wind and solar maps.

They've neglected to indicate the significant offshore wind resources, and the solar map suggests that there's nothing going on in much of the country when, in fact, solar is viable everywhere in the country.

Better maps are available at the Department of Energy Energy Information Administration website:

For instance, without pairing their map to the following text on wind and solar, you don't get the full picture of available resources:

Photovoltaic capacity grew by 76 percent between 2011 and 2012, according to the Solar Energy Industries Association. The areas shown in yellow above represent the top 20 percent of areas in terms of average annual solar energy potential.

Wind is second only to hydroelectric in renewable energy. It generates about 28 percent of renewable power and, with the extension of a production credit earlier this year, is expected to grow 7 percent in 2013. The areas colored orange are where wind speeds fall into the top two most productive categories, according to the National Renewable Energy Laboratory. In addition to the inland regions shown above, areas off the nation's coasts also hold great potential for capturing wind power.
