I'd say fuel..

But there's been so much artificial price raising and lowering over the years.. seriously.. running out of gas in the 70s? I really don't think k were ever gonna run out of gas.. certainly not in our lifetimes.. but they'll find one way after another to raise the prices.. of course shutting down pipelines and stopping drilling in our own country sure isn't helping..
