Back in the early '80's, OPEC got together and made a new plan: The amount of oil that each member could produce was to be in proportion to their
stated reserves.
Within a few short years, all of the major OPEC producers suddenly "found" enough oil to double their reported reserves.
Unfortunately, those same stated reserves have been used by the
Energy Information Administration to predict our future availability of oil.
It has recently become evident that OPEC cannot deliver on the production promises that they have been making for decades, which means the world must now turn to harder to process and produce oil reserves. (google "tar sands", "oil sands", "shale oil", "bitumen", "heavy oil")
Unfortunately it will take quite some time and quite a bit of capital investment to construct the necessary refineries that will bring new supplies of finished product (gasoline and diesel) to market.
Therefore you can expect energy prices to remain very high for the foreseeable future.
There will be no return to cheap and plentiful oil. The future will contain a mix of energy sources, all of which will be more expensive than in the past.
Stop filling dumpsters, as much as you possibly can, and everything will get better.
Just think it through.
It's not hard to do.
