Three Stimulus Package Priorities to Rebuild a More Equitable and Sustainable Economy

With the COVID-19 pandemic pushing our medical system to the brink and ravaging the nation’s economy, we must respond decisively and forcefully. Without a doubt, our nation’s top priority should be shoring up our public health efforts to keep people healthy and providing financial relief to the millions of people across the country who have suddenly lost their jobs.

At the same time, our leaders must start thinking ahead, creating strategies to revitalize the economy when this public health threat begins to subside. As members of Congress contemplate various economic stimulus options, our leaders should advance measures that emphasize job creation, benefit those most impacted by the pandemic, and rebuild the economy in a way that promotes the long-term interests of society.

California’s Electric Sector is About to Veer Off Track in Fight Against Climate Change

For decades, California has been a world leader in the fight against climate change. But as the years pass by and California’s climate change goals become increasingly ambitious, the pathway to achieve the state’s goals is becoming more challenging. California’s electric sector has, historically, been the shining star of decarbonization, but now that the state needs its electric sector to ratchet down emissions faster than ever before, California’s electric sector is poised to let us all down Read more >

Why Can’t California Shake Its Natural Gas Habit?

California is a national leader in clean energy generation, but to fully transition away from fossil fuels in the electric sector, the state will need to expand its focus beyond energy and start taking a hard look at capacity.

California has a resource adequacy program, which ensures that the state has enough electricity generating capacity at the ready to keep the grid reliable year-round. Up until now, the data about the types of resources (natural gas plants, solar, energy storage, etc.) being used to satisfy those reliability requirements has not been publicly available. But at the urging of UCS and other organizations, that information is now being made public.

So now the numbers are in, and they paint a startling picture of California’s continued reliance on natural gas. After taking you through the numbers, I’ll talk about some of the solutions we already have and the ones we might still need.

Sit down, folks. This will take your (energy nerd) breath away.

Why Isn’t California Turning Down the Gas?

California is currently going through a short-term hiatus on shutting down gas plants due to emerging grid reliability concerns. But in the long term, the state is well positioned to continue turning down the gas.

The Current War: Why Did Westinghouse (AC) Beat Edison (DC)?

As communities across California face widespread power outages and the debate over how to keep the grid reliable rages on, I decided to go to the movies for some historical context on our electric grid, seeing The Current War: Director’s Cut on opening night. With a big-name cast, my hopes were high, but the movie was just OK.

It’s a shame the movie wasn’t more compelling, because this is a fascinating story that deserves much more attention. The movie portrays the late 19th century “war” between George Westinghouse and Thomas Edison that would ultimately determine which technologies were used to build the foundation of the electric grid we use today. While Edison championed direct current (DC) systems, Westinghouse promoted alternating current (AC) systems, and the competition between the two was fierce.

While walking out of the theater, I couldn’t stop wondering: why exactly did Westinghouse’s AC systems triumph over Edison’s DC systems?
