The worst result was from Calgary, Canada. The city's power consumption actually went up 3.6% at the hour's peak electricity demand. Calgary's weather plays a large role in power consumption, and the city experienced weather 12 °C (around 22 °F) colder than the previous Saturday's recorded temperature in the inaugural year. Enmax, the city's power supplier, has confirmed that in all subsequent years, Calgarians have not supported the Earth Hour initiative, noting that power consumption changed only marginally during the hour in 2010 and 2011 (1% or less) and in 2012 and 2013 showed no appreciable change in power usage at all.
