Editing Heat wave (section)

=== Power outages ===
Heat waves often lead to spikes in electricity demand because there is more use of air conditioning. This can create power outages, making the problem worse. During the [[2006 North American heat wave]], thousands of homes and businesses went without power, especially in California. In Los Angeles, electrical transformers failed, leaving thousands without power for as long as five days.<ref>{{cite news |last=Doan |first=Lynn |author2=Covarrubias, Amanda |date=27 July 2006 |title=Heat Eases, but Thousands of Southern Californians Still Lack Power |url=http://www.latimes.com/news/local/la-me-heat27jul27,1,4111447.story |access-date=16 June 2014 |work=Los Angeles Times}}</ref>
The [[early 2009 southeastern Australia heat wave]] caused major power disruptions in the city of Melbourne. They left over half a million people without power as the heat wave blew transformers and overloaded a power grid.
