The Blockchain.info number he bases it on comes from:
* Electricity consumption is estimated based on power consumption of 650 Watts per gigahash and electricity price of 15 cent per kilowatt hour. In reality some miners will be more or less efficient.
ASICs (which I believe are the majority of the hashrate nowadays) are more on the order of 10 W/GH (Block Erupter claims 7.5 W/GH/s, the Butterfly Labs 5 GH/s ASIC looks like it's around 6.5 W/GH/s).
