The Electrical Grid: Keeping the Lights On

The electrical grid is the most important innovation of the 20th century. What started out as a series of micro grids powering small areas eventually grew into what is now widely considered the world's biggest machine. But this machine needs a tune-up.

Our energy demands are on the rise and severe weather events caused by climate change are becoming more frequent. Luckily, renewable energy and modern smart technology are helping us reimagine the grid so we can keep the lights on.
