Researcher is working to predict electric power blackouts before they happen
The largest power outage in United States history, the 2003 Northeast blackout, began with one power line in Ohio going offline and ended with more than 50 million people without power throughout the Northeast ...
Experiment makes energy savings a game
Let's face it: We're energy hogs. We want more light, we flip a switch. If we're hot, we crank up the AC, without a second thought on the power grid strain. It's what economists call inelastic demand – the resource is widely ...
