Dear Friend,

Back in May, the Sanders Institute asked me to write to you all about something I had just started building: A new movement built around the power of the Sun, something that can help us go on offense for our clean energy future. Thanks to the support of activists across the country, Sun Day is here―and it’s going to be big.

On Sunday, September 21, people around the country are coming together to stand up for solar power! Find an event near you!

Sun Day is part of a larger strategy to change the conversation around clean energy. While environmentalists play inspired defense in court, trying to rescue money that was promised under the IRA and preserve the authority that Congress granted the EPA, something significant has changed since Trump’s first term:

That’s the fact that power from the sun and wind is now the cheapest power in the world. Scientists and engineers have done their job—we live on a planet where the cheapest way to produce electricity is to point a sheet of glass at the sun. That’s what really has Big Oil terrified, and why they’re pumping so much money into politics. They’re desperate to slow that transition down.

We’re desperate to speed it up. That’s why we’ve scheduled a big nationwide day of action we’re calling SunDay for the autumn equinox on Sept. 21. All kinds of groups—including our friends at the Sanders Institute—are coming together in a big coalition to celebrate renewable power. There will be EV parades and people opening their homes to show their heatpumps to their neighbors. Think concerts, think teach-ins—think all kinds of actions designed to show Americans that this is no longer “alternative” energy but the obvious way forward.

Please join in—go to SunDay.earth and get involved. This is the big achilles heel of the other side, and the big chance to make energy not only cleaner but more affordable for all of us. Time for us to really step up!
