Green Tech

Here's a real good piece by Thomas Friedman for green tech. Basic argument is regardless of reality or non-reality of global warming, 2 other key trends make investing in green tech crucial
1. The world population is projected to increase by 2.5 billion people over the next 40 yrs. That's a 37% increase in population.
2. It's going to take a lot of energy to "feed, clothe, house and transport" an additional 2.5 billion people who want to consume more like Americans.
3. If we don't invest in green energy and energy alternatives, our enemies who dominate the oil producing parts of the world will only grow that much stronger.
4. Plus innovation is what we're historically good at - take advantage of our strengths.

Anyhow, I very much like the way he thinks on green tech - and note the case above is independent of how I may or may not feel about climate impacts.
