Clean energy is getting its own national day of action. It’s about time.

Canary Media’s ​“Electrified Life” column shares real-world tales, tips, and insights to demystify what individuals can do to shift their homes and lives to clean electric power.

Heard of Earth Day? Get ready for Sun Day.

On Sept. 21, a Sunday of course, thousands of people will gather across the U.S. to spread the message that the clean energy revolution is here. By harnessing the sun — whose thermal energy also gives rise to wind — instead of burning fossil fuels, we can all enjoy cleaner air, lower utility bills, and a host of other benefits.

The day of action is the brainchild of climate journalist and activist Bill McKibben and is being spearheaded by nonprofit communications lab Fossil Free Media. They and a coalition of dozens of advocacy groups are bringing people together on Sun Day to celebrate the progress humanity has made in advancing and adopting renewable energy — and to push for a faster transition away from fossil fuels.

Helping Americans understand all that clean energy has to offer is more urgent than ever, as the Trump administration continues to target renewables, rapidly phasing out tax credits for solar and wind, halting offshore wind development, and maligning battery projects.

Meanwhile solar and wind power are booming globally. And even in the U.S., more than 90% of new power capacity installed last year came from solar, wind, and batteries. Everywhere, the cost of building renewable power is plummeting, making solar and wind the cheapest sources of new electricity.

“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,” writes McKibben in his new book ​“Here Comes the Sun: A Last Chance for the Climate and a Fresh Chance for Civilization,” which shines a light on the growth of renewables.

“The general public just isn’t aware of how far clean energy has come,” said Jamie Henn, a longtime climate activist and now head of Fossil Free Media.

Individuals and groups have planned more than 150 community events around the country for Sun Day so far. In New York City, organizers are hosting a festival with informational booths, performances, and face-painting. Around Clemson, South Carolina, residents with homes powered by rooftop solar are throwing open their doors to public tours. In Moscow, Idaho, people will be able to test-drive their neighbors’ zero-emissions cars at an electric-vehicle fair.

​“It’s going to be a beautiful day,” said Antonique Smith, a Grammy-nominated singer and actress who cofounded the nonprofit Climate Revival and has assumed the role of Sun Day ambassador.

Inspired by Martin Luther King Jr.’s organizing in churches for the Civil Rights Movement, Smith visits houses of worship to explain that there’s an alternative to the fossil fuel plants that spew cancer-causing pollution disproportionately in disadvantaged neighborhoods.

“Clean energy and solar are so important, especially to communities of color and poor communities,” Smith told Canary Media. ​“How wonderful is it that we have this solution? … It’s not a luxury anymore.”

At climate events, Smith often sings a slowed-down version of The Beatles’ ​“Here Comes the Sun” to honor the power of activism and clean energy. Her rendition is also the anthem for the upcoming day of action, and she’ll be performing the song at Sun Day extravaganzas in Brooklyn and Times Square, she said.

Sun Day will also give people a chance to reflect on the risks of a rapidly warming world, according to the Rev. Fletcher Harper, executive director of GreenFaith, a global interfaith environmental coalition. GreenFaith is working with more than 30 partner groups, representing a couple hundred congregations, that are hosting Sun Day gatherings, including a climate-justice pilgrimage in Harrisburg, Pennsylvania.

“When you look at the impacts of climate change — dangerous levels of heat, drought that forces small farmers around the world off of land that sustained their families for generations, fires that destroy people’s homes, and floods from severe storms — it’s the destruction of the environment that creates enormous human suffering,” Harper said. ​“It’s just wrong. … And the crime is that it’s preventable.”

The fossil fuel industry, having peddled its products while knowing the existential threat they pose, is a candidate for ​“one of Dante’s inner circles,” he noted wryly.

The moment for a clean energy movement

Sun Day’s organizers aim to spark a widespread popular movement whose influence is felt long after the day of action.

“People power is just this incredible way to unlock progress more quickly,” Henn said. ​“And that’s what we need to meet the kind of climate targets that we have in place.”

With all of its economic and societal advantages, clean energy might be inevitable, but ​“we can’t let this take 40 years,” he noted. ​“We need it to happen over the next five to 10 years, [which] will require a real mobilization.”

Solar and wind projects are increasingly hitting resistance at the local level.

“We’re just getting completely outplayed,” Henn said. The fossil fuel industry has ​“invested in front groups [and] field campaigns” to spread misinformation through Facebook and organize people against clean energy, he noted.

Sun Day will bring together people who can call on local leaders, regulators, and representatives to deliver clean energy now. Indeed, Fossil Free Media is already helping build those local grassroots networks, said Deirdre Shelly, who’s leading organizing efforts for the big day.

How to get involved in Sun Day

Want to participate but not sure where to jump in? Start by checking out Sun Day’s map to see if an event is already scheduled in your area. If you want to plan your own shindig, organizers have pulled together a toolkit to help you realize your vision, be it a solar-panel show-and-tell, an e-bike parade, or a clean energy rally turned block party. You can also tap one of the dozens of climate, justice, and grassroots groups that are core partners for the day of action, including 350.org, EcoMadres, Sierra Club, Solar United Neighbors, and Third Act, to see if they’re looking for Sun Day volunteers.

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

Eager to hear more about Sun Day and the meteoric rise of clean energy? I’ll be interviewing McKibben about both in our discussion of his new book, ​“Here Comes the Sun.” Register to join us on Wednesday, Aug. 27, at 2:30 pm ET — and bring your questions!
