Nuclear and coal plants cost more to build. Transmission investments have grown 10x over the last decade. But somehow solar+battery manages to get cheaper every year. Read More
Energy from the wind and sun is intermittent and often unpredictable. Critics point to this as the fatal flaw of renewable energy and the reason electricity prices rose in places aggressively adopting it. Is this true? Read More
There are five trends driving the replacement of fossil fuels with clean energy from the sun and wind, and none of them require sweeping new legislation or technology breakthroughs. Read More
It’s tough to make predictions, especially about the future. — Yogi Berra At last week’s Intersolar conference in San Francisco, keynote speaker Tony Seba made a compelling case for near-term disruptions in energy and transportation. In particular, his slide on solar projections really caught my attention. It turns out that government solar predictions have consistently… Read More
Every four years, one thousand solar scientists from across the world gather to peer into the future of the solar industry. The event is called the World Conference on Photovoltaic Energy Conversion (WCPEC). The seventh such event is taking place this week on the big island of Hawaii. I decided to attend the conference to learn… Read More
Spreadsheets, analysis, and predictions are all great. But nothing compares to the free market if you want to really understand the trajectory of clean energy pricing. A recent bidding process for utility giant, Xcel Energy, just rocked the industry. Bids for clean energy projects including solar, wind, and batteries, came in lower than anything ever… Read More
After months of paralyzing uncertainty, President Trump’s staff announced their decision on solar tariffs today. Here is a high-level overview: Quick Facts Imported solar is subject to a 30% tariff The tariff amount will reduce 5% per year over 4 years to 15% The first 2.5 GW of solar cells imported each year will not… Read More
Every single solar project, big or small, gets assembled one at a time on a roof or in a field. But what if you could pre-manufacture solar projects in a factory, instead? Could you do to solar what Henry Ford did to cars and make solar even more affordable and available to virtually everyone? What… Read More
In mid-November, forty of the brightest minds in solar gathered just outside New York City. Their goal was simple yet audacious: find a way to dramatically reduce the cost of solar installations by re-inventing how they are designed and built. The cheaper we can make solar, the faster we accelerate the shift towards clean energy.… Read More
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
