Many people do not know the impact of the Dept. of Energy on their lives. This might explain why there isn't a lot of brouhaha when someone who isn't a scientist or an engineer is appointed as the Secretary of the Dept. of Energy, unlike, say, the Director of the FBI. Yet, DOE makes a lot of important decisions that directly affects how we live today, and certainly how we will live tomorrow.
So it is appropriate at this time to highlight a very comprehensive overview of the DOE for the past 10 years. The department has just released a document titled A Decade of Discovery. It highlights all the various discoveries and research work sponsored by the DOE. You can read the press release here, and you can read the actual document as well.
