It is a shame.
Carter had the fore thought that we needed to address our energy situation after the oil embargo. The creation of the DOE was supposed to find those long-term solutions.
Sadly the DOE has been a complete failure with the Solyndra mess being the most recent in a long line of crony payback projects funded through the DOE.
Overall energy technology has made tiny steps forward in the last 30+ years for the trillions invested.
We could be in a much stronger position to handle the coming storm if the substance to meet the need had followed the hope in the vision.
