the amount of gas in alaska would provide america with gas for about a month, and it would cost a shitload to even get setup for the drilling process. its just not worth it
and improving production of gas...another reason the price is rising besides the crappy us economy, is that comsumption is at a faster rate then production. waaaaay faster. oil takes forever to actually become oil, that is millions of years, so to speed up the process of the oil resource is impossible. oil is getting more expensive because there's not much left. because consumption is at a higher rate of production, the amount of oil left is decreasing rapidly
this site has a ton of info on the oil curve, how much is left, how much oil is actually being used, how much has to deplete until it becomes a huuuge problem...and other stuff
