> It takes an estimated 1,449 kilowatt hours (kWh) of energy to mine a single bitcoin. That’s the same amount of energy an average U.S. household consumes in approximately 13 years.

I consumed 420 kWh last month (cost $74).... so it would be more like 3.5 months and not 13 years... and more like less then $255 total... what am I missing? Did they forget a few zeros somewhere?
