The green energy revolution seems to make sense. If you look at how economies have recovered from past recessions, it's often due to a paradigm shift (ugh....consultant speak). For example,
1920's --> buying stock on margin
Great Depression --> WWII
1981 --> personal computer
1995 --> internet
mid-2000's --> real estate
2008 --> ??
Not all recoveries have great up-side, but seems to be progressively better.
