A tax on gas is better than nothing. Prices this low are unstable, and it will result in a bad spike. Whether in a few months or a few years, we don't know. But we do know that when gas is this cheap, people buy less fuel-efficient cars, and general usage goes up. We're gonna burn through the surplus, and then we're gonna pay.
In addition to that, we're using up the global oil reserve. I realize that a lot of people - mostly Republican people - like to argue that we just need to come up with a new power source before we use up all the oil, which gives us plenty of time. I see that as incredibly short-sighted. I think the problem is that people with no chemistry background tend to think of running out of oil as generating crises in the oil and gas markets. From my perspective, this is only the lesser part of the problem. I'm confident we CAN develop new energy sources. The problem is that when we run out of oil, we don't just run out of oil and gas. We also run out of everything we make with synthetic materials derived from building blocks distilled out of oil and gas. Spoiler alert: that's EVERYTHING synthetic. When we run out of oil, we run out of plastic. No more PVC, polyester, vinyl, anything. The vast majority of pharmaceuticals are synethesized at least partially from components of crude oil. So no more meds. No more rubbing alcohol. No more pesticides. No more refrigerants for our refrigerators and air conditioners. The building blocks of most of our soaps and detergents are oil-based synthetics. Paint. Cosmetics. Synthetic vitamins and food additives (flavors, colors, etc.) Kevlar. Carpet fibers. Plastic electronics. I could go on for hours.
I think there's a vast underestimation amongst the general public of how many things they use or appreciate on a daily basis are derived from petrochemicals. Thinking of running out of oil as a gas and oil problem is horribly misguided. We've been led in that direction by undereducated and oil-funded politicians and political advocates, but it's a blatant untruth. Obviously we can come with alternative energy. That's relatively easy. Coming up with an alternative source of small molecules for synthesis is almost impossible. That, of course, is why nobody is paying big bucks to advertise the problem. But it's very real.
