No. Two more important words: Free Markets.
Those environmentally sound innovations that CAN MAKE IT ON THEIR OWN without gub'ment tax exemptions and (massive) subsidies, will be the real technology which moves us forward.
Check out the innovations in diesel car engines just in the last 20 years for example--NOT from giant subsidies, rather from consumers desiring efficient, powerful, inexpensive and clean-burning transportation.
If you haven't driven a diesel car lately (mostly German brands) you should....they are difficult to tell in driveability from gasoline cars...and tend to get over 40 mpg too.
Most of the advances in diesel technology you speak of have been related to tier standards. Is the new technology cheaper to run LONG TERM? I would say no.
I know that gubmint mandated ULSD destroyed the oring seals on my HPFP... which I was able to C/O on my own... without removing the pump from the car.
Algae oil produces more BTU/acre that soybeans. Of course the cheapest thing to to is to poke holes in the ground... but I wouldn't mind having my own Algae Oil pilot plant... too bad the gubmint would throw me in jail if I tried that and didn't pay excise taxes.
