There are very few government officials out there calling for people to destroy the environment.  Some of them are even quite vocal that we need to work to save it in any way possible.  But the government - as an entity - does not need to push any green tech

on the populous.

The only way for the technology to take off is for the industry to push its development.  The only way the industry will push the development is when a need arises.  Right now, there isn’t much need for cheaper fuel.  Even with gas prices running over $3 per gallon, people just kept fueling up the cars.  The initial scare did cause a flood of used SUV’s to hit the market, but the automobile industry responded in kind with more fuel efficient SUV’s.

There has been some talk lately that the government should support financial the green industry.  It was even a subject in a recent republican presidential debate.  Subsidizing anything is a bad idea.  It causes innovation to stagnate.  Necessity is the mother of invention, not government support.  Hopefully, the green technologies will find their own footing and take off.  Until that happens, the government shouldn’t get involved.
