And maybe other routers last a bit longer. You can probably get an idea from extrapolating these figures [1]: RAM: 11.4 kWh and 32 L water for 32 MB chip CPU: 1.4 kWh and 5.9 L water per square-cm silicon wafer LCD: 553 kWh and 2394 L water for a 15" monitor A dragonball CPU (2 dies each .343cm x .343 cm) requires 0.3 kWh and 1.4L. The impact of producing a CPU seems low to me, especially when compared to the RAM. Needs to do some more research ... :) m [1] Environmnetal Implications of New Wireless Technologies: News Delivery and Business Meetings by Michael W.
