The problem is that their is nothing better than oil as a transportation fuel.
Depends on what "better" is - less polluting might be "better". Perhaps you meant "energetically efficient", but then we'd have to limit that to the kind of combustion engines we currently use.
If there was something better available, we would be using it already. People buy the best product they can get.
You actually have part of that right - they use the best alernative available to them. The best alternatives available are not always the best that exist - they're the best that corporations conspire to provide. Why do we not have a large trolley system in Los Angeles (any more)? It wasn't dismantled because people didn't use it.
People buy the only product they can get when only one product is made available. When better products are available, they become vocal and committed. Recall the outcry of electric vehicle leasors when those vehicles were pulled out of the market.
There has been no actual free market activity that chose oil as the "best" product. An industry created the market because it could make a mint. And it has.
Think about it. A gallon will drive a 2 ton vehicle at high speeds nearly 20 miles.
Think about it. Virtually no typical consumer on today's streets needs a 2 ton vehicle. The vast majority of traffic does not require high speeds, most trips are within miles of home.
Try just pushing that same vehicle 100 feet and you will realize how much energy is contained in a relatively small volume.
The same could be said for electricity (available from renewable sources), hydrogen (which I am aware has origination problems), and even steam. Not to mention used cooking fat, for goodness sake.
Indeed, some fuels are much more efficient - and would be a fiasco on public streets.
The issue, then, isn't really about efficiency or consumers picking the best product that fits their needs. These are red herrings, used to misdirect.
It's about entrenched business interests.
And that's the real argument, isn't it?
There is not inexpensive transportation fuel available that is as energy dense and as easy to transport to markets.
If it's so safe, why have there been so many production accidents in the news over the past year? How many times have residents of Richmond, CA had to stay inside their homes due to another explosion and fire?
We don't use oil because it's "the best" - we use it because it is entrenched. It is convenient. It is status quo.
