The green economy may one day involve a lot of blue shirts.

GreenBiz.com's Joel Makower has an interesting article about Best Buy's potential gain from a greener, more energy-efficient future.

Addressing climate change is going to require the help of electronic gizmos -- from smarter appliances to in-home wind and solar generators. It isn't a stretch to see how Best Buy could play a key role in helping people buy and install cleantech, smart-grid products.

Best Buy is entering the electric vehicle market this month on the West Coast, selling a line of high-tech electric motorcycles. That could be a bridge to other electric vehicles, Makower speculates.

"It's a compelling story line, to be sure, but equally important is that it illustrates the potential for incumbent companies to be key players in advancing green technology."
