With changes, the grid can take it
Over the next two decades, the U.S. electric grid will face unprecedented technological challenges stemming from the growth of distributed and intermittent new energy sources such as solar and wind power, ...
Penn historian discusses the threat birds posed to the power grid in 1920s California
In 1913 in Southern California, two 241-mile-long electric lines began carrying power from hydroelectric dams in the Sierra Nevada to customers in Los Angeles—a massive feat of infrastructure. In 1923, ...
Mathematical formula boosts renewable energy efficiency
A mathmatical framework for rating transmission lines aims to help relieve power grid congestion to make more efficient use of renewable energy.
European to capsule leaving space station, skipping test
A European cargo ship is set to depart the International Space Station this weekend. But it will re-enter the atmosphere and burn up the next day, skipping a special descent test because of a problem.
