> an average electricity cost of 13.19 cents/kilowatt-hour

Source? The link supplied uses 5 cents/kWh, which is also an assumption on their part that they do not explain either.

There are lots of reports of 'seasonal mining' occurring in China, where mining operations are occurring in areas with very cheap or completely free electric, generally because the costs of producing the electricity are fixed, rather than scaling up or down with demand (geothermal / hydro / other renewables).

I got that figure from Google, but it's the average residential rate and I guess you'd get the industrial rate for a large operation(my power company charges 5.95 cents for that).
