[Serious] The Post-Technological World.

[AFTT47]

We have had solar technology, for example, for almost a century. But greed has kept the planet on fossil fuels. 

I'm surprised at you, Brian. That's conspiracy theory nonsense.

Yes, we have had solar technology for quite some time but it has only recently become economically viable. Until recently, it cost more to manufacture a solar voltaic panel than the value of the energy that panel would produce over its entire lifetime. Eschewing a technology that is hopelessly noncompetitive is not greed - it's common sense.

Now that the situation has changed, we are seeing rapid adoption of solar (and wind). Yes, it's because of favorable economics but it's a matter of practicality, not greed. Not to say that greed doesn't exist but it had nothing to do with the lack of adoption of solar before it was viable.
