This seems unbelievable:
This averages out to a shocking 215 kilowatt-hours (KWh) [sic] of juice used by miners for each Bitcoin transaction (there are currently about 300,000 transactions per day).
215 kWh is an enormous amount of energy.
Even if mining bitcoins uses a lot of processor power, 215 kWh is still enormous.
Are they confusing all transactions with just mining?
