I recommend this long but very good piece: http://waitbutwhy.com/2015/06/how-tesla-will-change-your-life.html
In particular, the bits about how companies act in a free market, how they externalize costs, and how the auto and petroleum industries (especially the latter) do their best to make profit, staving off the desirable and inevitable change. Mankind has been on a petroleum binge for longer than it should have been, thanks to say Standard Oil and Henry Ford.
