Vaclav Smil – Drivers of environmental change: focus on energy transitions – YouTube

Vaclav Smil on the the scale and difficulty of executing an energy transition for the civilization.  “Calculate with me!” he says, before diving into a bunch of order-of-magnitude demonstrations that this is all much harder than we might like to think.  He’s very pessimistic about the large-scale integration of intermittent resources, and also about humanity’s ability to initiate a change voluntarily.  Would like to understand those positions better… and still continue to disagree with them.  The talk is long and rambling, but he’s so clearly engaged and emphatic that it doesn’t matter.
