IMO usage will have to decrease before anything can be fixed.

Virtually everything in our culture seems to have at least 90% waste of energy, and industries built around that waste wasting even more, and so on ad nauseum. We just don't have a sustainable mode of living.

If usage doesn't decrease, it's very possible the shit will hit the fan. The problem with our system is there's really nothing keeping consumption in check ... but rather is rewarding it.

I remember a semi-factual anecdote about a company that built a great product that never broke, and never had any problems. Unfortunately, the company went out of business, since they couldn't sell more than one per household. Our system is really built on creating consumption, not permanent solutions.
