Here's the problem.  CAFE standards, or any other standards imposed by governments based on incomplete, irresponsible, or completely faked climate data actually cost us more in fuel and reduce fuel economy, creating a need for MORE investment in fossil fuels, not less.  

 

Funny how you post information that is actually full of falsehoods and cherry picking, and someone complements your brain.  Fossil fuels ARE biofuels.  Carbon is the biological element.  It's what every biological entity on the planet is created from.  I agree that there are better energy sources out there, but solar, wind, and biofuels have been around just as long and longer than fossil fuels, and none are efficient enough or powerful enough to be used regularly without supplementation from fossil fuel sources.  They've been around that long and have never been a growth market, the thought that with a little government forcing it would suddenly become a market success is silly in and of itself.  It's been tried, and tried, and tried again.  It always ends in bankruptcy and people getting screwed out of tax dollars.

 

Solar energy, as we currently know it, will never be a viable, consistent source of energy.  Wind is more dangerous to plant, animal, and human life than any other energy source, and biofuel will end up being a nonstarter simply because what we know as "biofuel" doesn't carry the same energetic potential as fossil fuels, it isn't strong enough, and no invention is efficient enough to put it to good use on a large scale.

 

Hydrogen and electric will be the eventual one two punch that allows for us to curb fossil fuel reliance, but that is still years out, the process is still too complicated and the machines too bulky and heavy for commercial use.  I like seeing research into these things, until other sources of energy that have enriched and improved countless lives gets bashed for political purposes.  Everyone needs their soapbox as it were.
