Economic Benefits of Increasing Electric Grid Resilience to Weather Outages

In June 2011, President Obama released A Policy Framework for the 21st Century Grid which set out a four-pillared strategy for modernizing the electric grid. The initiative directed billions of dollars toward investments in 21st century smart grid technologies focused at increasing the grid’s efficiency, reliability, and resilience, and making it less vulnerable to weather-related outages and reducing the time it takes to restore power after an outage occurs.

Did you know: a typical bolt of lightning is about 3 miles long and heats the air immediately surrounding the bolt to over 20,000 degrees Celsius? That's three times hotter than the surface of the sun. For many Americans, summer isn't complete without an exciting thunderstorm to break up the heat. This electrifying photo was taken by Sandia Labs photographer Randy Montoya during a summer storm on July 21, 2013. The lightning illuminated the Redstone rocket that stands in front of the National Museum of Nuclear Science & History in Albuquerque, New Mexico. | Photo courtesy of Randy Montoya, Sandia National Laboratory.
