National Day of Action for Clean Energy, ‘Sun Day’ is Coming Up September 21, 2025

The most cost-effective and eco-friendly options for all homes, buildings, and transportation around the world are electric vehicles (EVs) and renewable energy. EVs and renewables fall under the umbrella term of clean energy. Now, the United States has its own fun and exciting national day of action to celebrate and support these important, groundbreaking clean energy technologies, Sun Day 2025, happening September 21.

On August 25, Canary Media reported on the event. On September 21, 2025, a Sunday, naturally, thousands of people across the U.S. will gather to celebrate Sun Day, a nationwide day of action to spotlight the clean energy revolution.

Instead of burning fossil fuels, we can harness the sun, whose thermal energy also drives the wind, to enjoy cleaner air, lower utility bills, and stronger communities. Sun Day is designed to spread that message far and wide.

The idea comes from climate journalist and activist Bill McKibben, and the effort is being led by Fossil Free Media, alongside dozens of advocacy groups. Together, they want Sun Day to be both a celebration of how far renewables have come and a rallying call for a faster transition away from fossil fuels.

That urgency is underscored by recent policy setbacks. The current administration is actively rolling back renewable energy support, cutting tax credits for solar and wind, halting offshore wind projects, and disparaging battery storage. The federal EV tax credit was cut, now available only through the end of September.

Yet the reality is undeniable: solar and wind are booming. Globally, they’re the fastest-growing sources of power. In the U.S., over 90% of new power capacity added last year came from renewables and batteries. Costs have plummeted, making them the cheapest new electricity available. EVs broke sales records in August.

“We still think of photovoltaic panels and wind turbines as ‘alternative energy,’ as if they were the Whole Foods of power, nice but pricey. In fact, and more so with each passing month, they are the Costco of energy, inexpensive and available in bulk,” McKibben writes in his new book Here Comes the Sun.

Already, more than 150 community Sun Day events are planned nationwide. From a festival in New York City with booths and performances, to rooftop solar tours in South Carolina, to EV test-drives in Idaho, organizers are showing how clean energy is improving lives.

Grammy-nominated singer and activist Antonique Smith, cofounder of Climate Revival, is serving as Sun Day’s ambassador. She’s bringing the message of clean energy to houses of worship, highlighting its importance for disadvantaged communities disproportionately harmed by fossil fuel pollution. Smith will also perform her rendition of Here Comes the Sun at Sun Day celebrations in Brooklyn and Times Square.

Faith groups are joining in as well. GreenFaith, a global interfaith coalition, is supporting Sun Day events at congregations across the country, including a climate-justice pilgrimage in Pennsylvania.

Organizers hope the movement extends beyond one day.

“People power is just this incredible way to unlock progress more quickly,” said Fossil Free Media’s Jamie Henn. “We can’t let this transition take 40 years. We need it to happen over the next five to ten.”

As Henn put it:

“We definitely will need everyone to be a part of this fight. Join us for Sun Day.”

EVinfo.net’s Take: BEVs Better Than ICE or Hybrid, But Alternatives Better Than All of Them

In a 2023 interview for America Walks, McKibben praised electric vehicles as the most eco-friendly vehicles available today. However, he also stressed that instead of just replacing internal combustion engine (ICE) and hybrids with battery electric vehicles, (BEVs), people should consider car-pooling, walking, biking, and using public transportation as much as possible as well, for the greatest positive impact to the environment.

“The unfettered reign of the car has been a problem in so many ways. It’s distorted everything from what our communities look like, to how we relate to each other to, of course, the carbon content of the atmosphere. And it remains the single biggest way that Americans heat up the planet,” said McKibben.

“Now, there’s obviously lots of important and interesting stuff going on [in the transportation sector] right now. The rise of the EV, for instance, is a big, big improvement over an internal combustion car — if you need to drive a car, then that’s what you should be driving. But just swapping one out for the other would be missing real opportunities,” continued McKibben.

EVinfo.net agrees. Decreasing the use of all private vehicles, regardless of powertrain, would be best for fighting global human-caused climate change.

I drive an EV, but as little as possible. I still haven’t bought an eBike, instead still using my old-fashioned, pedal-powered bike which saves money and the environment at the same time. I also car-pool, walk, and use public transportation as much as I can.
