Are we running out? We will one day but with new huge fields being found in the U.S and continued stalling of actually tapping these fields will make any possibility of running out of oil much faster.

Are we relying too heavily on certain sources of crude? Yes, The middle-east gets a majority of the money for crude oil. For national defense reasons, we import way too much oil, then again this is one reason why we need to keep our oil reserves as well.

What needs to be done in the aviation community to conserve? APU usage, tugs, flex climbs? Flying slower is about the best option. It seems to be working for southwest as they saved I believe $42 million on making flights a couple minutes longer.

What do you see as the best alternative to Jet A? I believe the only alternative is Biodiesel, but that comes with a lot of problems such as rising food costs and gelling at cool temperatures.
