The U.S. Electric Grid vs. Extreme Weather

On Sunday, Hurricane Irene weakened to become Tropical Storm Irene – but not before leaving at least 4 million homes without power and causing fuel shortages along the United State’s Atlantic coast. This hurricane brought on-land wind speeds of more than 85 mph in the continental United States, and maintained its hurricane status through most of its trek north. Though the storm had diminished... Read More

An Electric Power Industry Evolution – From Provider to Partner

This post was originally published on 8/19/2011 Scientific American’s blog, Plugged In. On February 1, 2011 a sudden cold snap and severe winter storms sent electricity demand in Texas through the roof. In a single hour, temperatures dropped almost 30 degrees. And, as temperatures dropped, the state’s power plants were unable to keep up with the growing demand. The resulting series of blackouts affected... Read More

Energy Efficiency for Economic Strength

This post was originally published on 8/4/11 on Scientific American’s blog, Plugged In. In the face of this summer’s debates on how to manage the nation’s current debt load – which came to a temporary cease fire on Tuesday with the passage of a bill that will raise the government’s debt ceiling – I found myself looking back at speeches made by President Obama where he emphasized... Read More
