Wired.com explains why the billions handed out by the DOE to support clean-tech stifle innovation and hinder competition “by reducing the flow of private capital into ventures that are not anointed by the DOE.”
It has also actually led to layoffs:

Aptera Motors has struggled this year to raise money to fund production of the Aptera 2e, its innovative aerodynamic electric 3-wheeler, recently laying off 25 percent of its staff to focus on pursuing a DOE loan. According to a source close to the company, “all of the engineers are working on documentation for the DOE loan. Not on the vehicle itself.”

Personally I would rather that the winners of the clean tech development races win by superior design and innovation rather than by political favor.
