Imagine you live in a remote village where the only source of water is delivered monthly by truck.

00:13

This, of course, costs money. But then you discover a massive water source below the village: limitless water, but currently unreachable.

00:24

To access it, you’d need to dig a well. That would cost years’ worth of water trucking fees, But once built, you and all future generations would have unlimited water— for only the minor cost of maintaining the well.

00:41

So, what’s the best way forward? Continue trucking in water? Or build the well?

00:47

Is the trillion dollar price tag that comes with transitioning the world to clean energy worth the cost of investment?

00:55

Like the trucked in water, fossil fuels aren't free.

00:59

There are the costs of the actual fuels, which, adjusted for inflation, haven't changed much for 140 years.
