The Annual Energy Review published by the Energy Information Administration
http://www.eia.doe.gov/emeu/aer/overview.html
This website has every fact and statistic on energy in the US that you could ever imagine and probably a bunch you never could. I just looked at the Energy overview, and even that its packed with information on how much energy we use, how much we produce, how much we buy, what kinds (renewable, coal, gas), where it comes from and so much more! It also breaks down energy consumption by state, which is interesting.
However, it's important to note that these are raw statistics. Its not light reading. This is definitely a resource older students and teachers. However, it might have interesting curricular potential. Students can look at this data in math classes; they can use real world data in their exercises while simultaneously learning about sustainability.
