Usually when the power goes out and there isn't a clear weather-related reason, I assume someone probably ran their car into something important.
But according to a number of recent news reports, it's more likely that the cause is animal interference. It seems to be an industry-wide problem.
TransGard, the maker of the patented fence that now protects 2,500 substations, uses stories of animal sabotage on its website to promote its products.
They also note that wildlife interference with power equipment is the most common cause of outages for public power utilities, according to the American Public Power Association.
But even the Atlantic recently published the story of the monkey who caused a nationwide power outage in Kenya.
