I agree that 13% is not a small share. But then, to replace the fossil fuels, we need to manufacture electric cars at affordable prices. Right now, they are out of reach for the vast majority of the Americans. And the future supply of Lithium and Cobalt is not that assured.
I agree that for transportation, there is a long way to go before fossil fuels are displaced as the dominant source of energy. But the cars are already affordable, it's just production scale that's lacking. The Tesla Model 3 is beginning production (this week I believe), and Chevy has the Bolt, which is similarly priced in the $35,000 range and has a slightly better range. As for batteries, Tesla has the Giga Factory which is currently only operating at a fraction of capacity. When it is at 100% capacity, that single factory will be producing more lithium ion batteries than the rest of the world combined. They built that factory because they forecast that demand. The question is how quickly the demand will materialize
So the Tesla guys (Elon Musk, I guess) seem to be interested in oil prices surging
If the prices hit the mark of 100 dollars per barrel again, the gas prices are certainly going to rise as well, and that might make electric cars (Tesla included) more competitive. Though I don't know about how much affordable they will become overall since folks may just choose to drive their regular cars less. On the other hand, electric cars are still pretty expensive, and those who buy them most likely don't care about either gasoline or electricity prices
