Google's own published estimates are much lower (0.2g/request), but I'm not sure we can trust them. Google power consumption is 260e6 W according to http://inhabitat.com/infographic-how-much-energy-does-google-use/google-energy-use-infographic-2/ for a little more than 200e6 requests to 1 billion requests per day (who knows), that's 6Wh to a little less than 30Wh per request. Of course Google does more than answering to requests, but one should also take care of all the energy used outside google in the net. Therefore the 16Wh per request estimate is probably in the right range. I'm curious what the estimates would be for a server-centric computing model for teaching.
