Sorry, there is nothing to understand simply because your premise is FALSE.
Alternative fuels will never come about because LIBERAL environmentalists will insist on blocking them.
THAT is what the blockage is on those.
Until YOU understand the truth, you will always be a delusional troll.

"Alternative fuels will never come about because LIBERAL environmentalists will insist on blocking them."

Now, that's why it's so important to bring up the subject every time you have the opportunity. The more people just give up on the whole alternative fuel concept, the less people will know about it. May be you should make this point to American farmers (who can make a living growing biodiesel crops, for instance) and your local congress man instead of liberals who supposedly know everything and will block anything that is good for the country.

Other than that, you're right.
