While the bus is great, Cisco could stop pointing the finger at cities, and start engineering its switch and router products to use less energy. Only Cisco can change the carbon footprint of its own products. The fact is, networking components are almost never mentioned in articles on data center cooling problems. Go see what the power requirements and heat dispersion is for a 3800 router vs a 3600 router. The difference is rather significant and points to a problem that Cisco needs to address if they are not doing so already. I have yet to see any product come out that addresses this directly... The world needs green routers!
