So, what should we use as fuel in the meantime? People can't just stop driving gas/diesel vehicles because, at the moment, the auto industry can't even make them in sufficient quantities to fill the demand. The materials for EV batteries aren't that plentiful to make a fast switchover and they're still expensive- higher demand will just cause the cost to increase.
You need to look at the actual demand for energy- in theory, we should be able to use other sources, but oil/fossil fuels are still the best/least hazardous. Nuclear energy is still at the top of energy density, but the problem is still "what do we do with the waste?" when its decay is measured in 'half-life of thousands of years'.
The problem I see with having the markets as the sole means of dictating prices is due to greed. However, competition SHOULD keep the prices lower, but when you have OPEC controlling supply/demand outside of the US, it's out of our hands.
