Market forces are doing exactly what you say you want MTA, high gas prices are forcing a reduction in driving, people choosing to buy smaller, more fuel efficient cars instead of SUV's and pickups already, however, since most renewable energy technology other than wind is still a long way from efficient and affordable application, the only way to get where you want to go in the interim is an increase of domestic oil production to mitigate the crippling gas price increases if we don't... can our economy survive if crude hits $200 a barrel or more, we can start converting coal to fuel for transportation on a large scale as well.... what are we going to do when the truckers can't afford to drive anymore?
I don't see how a massive application of new government energy bureaucracies, and taxation is going to do anything other than create 1933 all over again, but then maybe that's the intent...,allowing Obama to be the next FDR so he can implement what the Left has always wanted, FDR's Second Bill of Rights.
There is no short term transition from a hydrocarbon based economy to a Green energy system, the costs and logistics of such a change are insupportable unless you plan on creating a dictatorial, socialists system where the government can impose change through force.
The real solution is for the government to let market forces work, get the government out of the subsidy business for all of our economy, any government research money that goes to energy companies is only going to end up in the stock options and bonuses the executives give themselves, it's not their money so why should efficiency mean anything , the longer they drag it out, the more money the government will give to them... if they're forced to use their own corporate funds for energy research they have to answer to the stockholders for inefficiency and incompetence, the profit motive will drive innovation some thing government bureaucracy has never excelled at doing... you just have to have a business friendly tax environment to make it work.
