Meet the microgrid, the technology poised to transform electricity

If we want a livable climate for future generations, we need to slow, stop, and reverse the rise in global temperatures. To do that, we need to stop burning fossil fuels for energy.

To do that, we need to generate lots of carbon-free electricity and get as many of our energy uses as possible (including transportation and industry) hooked up to the electricity grid. Electrify everything!

We need a greener grid. But that’s not all.

The highly digital modern world also demands a more reliable grid, capable of providing high-quality power to facilities like hospitals or data centers, where even brief brownouts can cost money or lives.

The renewable energy sources with the most potential — wind and solar — are variable, which means that they come and go on nature’s schedule, not ours. They ramp up and down with the weather, so integrating them into the grid while maintaining (and improving) reliability means finding clever ways to balance out their swings.
