Hawaii is a postcard from our electric future (Part 2)

Island power grids are a microcosm of the vastly larger grids that criss-cross the planet. In Part 1 of this series, we looked at how small islands are pioneering the path to clean energy. They are disproving conventional wisdom by showing that intermittent power from the sun and wind can successfully provide affordable and reliable… Read More

Islands: fruity drinks, sandy beaches, and the future of the electric grid (Part 1)

The shift to clean, local energy is a real challenge for many utilities. Their traditional planning models choke on the variability of solar and wind power. Self-generation from rooftop solar and improvements in energy efficiency threaten to end a century of revenue growth. Increases in extreme weather events are making blackouts more common. To get away from all these… Read More

California just made a huge commitment to Local Energy. On May 9,  California’s Energy Commission (CEC) unanimously passed a groundbreaking new building standard. Starting in 2020, all new homes in the state must be built with solar panels.

Three steps that will help Puerto Rico’s grid survive the next hurricane

On September 6, 2017, Hurricane Irma hit Puerto Rico and left a million people without power. Two weeks later, on September 20, Hurricane Maria finished off the job and destroyed nearly 100% of the island’s grid. In early October, the governor, Ricardo Rosselló, optimistically predicted that 95% of the power would be restored by mid-December. But,… Read More

My TED talk on accelerating the shift to clean energy

Electricity powers nearly every aspect of our modern, convenient lives. It’s so pervasive and easy that most of us take it for granted. But just behind the common electric outlet lies a system that is expensive, insecure, and, worst of all, dangerously dirty – the grid. For example, clean energy from the sun and wind… Read More
