Squirrels and their partners in crime cause about 10-20 percent of all power outages, according to the Washington Post. Squirrel-induced power outages tend to be more localized and more quickly fixed than those caused by storms, since one little rodent can only chew so much.
8%
What is the percentage of power outages caused by squirrels? The American Public Power Association reports that squirrels caused more than 8% of outages in 2018
Nearly 20 percent of weather-related outages were caused by cold weather and ice storms, and another 18 percent were caused by hurricanes and tropical storms. Only 3 percent of outages were caused by tornadoes, and 2 percent were caused by a combination of extreme heat events and wildfires.
Trivia. One Of The Most Frequent Causes Of Power Outages In The U.S. Is? There are dramatic things that cause power outages: exploding substations, ice storms that cripple the entire Eastern seaboard, and heat waves that engulf the country and place enormous air conditioner-driven strain on the power grid.

Duke Energy says squirrels cause the most outages; but snakes, raccoons, birds, and other animals knock out the lights when they get into power lines, transformers and substations.
Birds can sit on power lines and not get electric shocks because the electricity is always looking for a way to get to the ground. The birds are not touching the ground or anything in contact with the ground, so the electricity will stay in the power line.
This way, birds and squirrel don't get electric shock because current don't flow through their bodies due to the same voltage level i.e. there is no potential difference. So the current will bypass their bodies as their is a short path with very less resistance (in case of copper wire).
. Storms: Wind, heat, ice and snow are the most common causes of widespread power outages. 2. Trees: During high winds, or trimming by an untrained professional, limbs can come into contact with power lines and cause interruptions
