Rebecca J. Barthelmie and Sara C. Pryor: How do wind turbines work?

Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy, and is it possible to create a world powered entirely by wind? Rebecca Barthelmie and Sara Pryor ...

Lorie Wigle: Weaving a strong smart grid

Integrating disparate national electricity systems into a smart grid allows us to integrate renewable energy, be more efficient and empower consumers to use power wisely. But as we add intelligence to these systems, we introduce a vulnerability into it as well. Lorie Wigle outlines a new project to protect these complex and vital grids from attack.

Dan Jørgensen: How wind energy could power Earth ... 18 times over

Over the last two decades, the wind power industry has grown at a dizzying pace. (Fun fact: a single rotation from one of the world's most powerful wind turbines can generate enough electricity to charge more than 1,400 cell phones.) Building off this exponential growth, Denmark's climate minister Dan Jørgensen lays out his plan to end the count...
