The cheaper options aren't even cheaper, we're just ignoring the cost and subsidizing them. Suppose that a gallon of oil cost how much it took to produce, but also how much it costs to scrub the resulting CO2 from the air, clean up any spills and scrub any CO2 made during production and transport, plus pay the additional medical bills of the people who's health is affected both in production and from the resulting air pollution? That price would be a hell of a lot higher, but we instead just pretend we aren't paying those costs (even though we are and will).

But yeah, the people with the most money and the ones making the laws don't have to pay those costs now. They can just pretend nothing is wrong til they're dead, let someone else hold the bag later.
