POWER

摘要

A 2006 study at Lawrence Berkeley National Laboratory found that power interruptions cost the economy about $79 billion annually, or about one third of national electric spending, thanks to our aging grid. Meanwhile, energy usernis expected to grow by 1,150 terawatt-hours-the equivalent of adding 13 New York Cities-by 2030. A smarter power grid will surely help, but we'll need additional innovations like these to keep up with spiking demand.
