BOULDER, Colo. – Last night, the Boulder City Council approved a measure to transition to 100 percent clean, renewable electricity by 2030. The Council considered the move as a major step toward reaching the city's longer-term goal of reducing its greenhouse gas emissions by 80 percent by the year 2050.
Sarah Huntley, the city's deputy director of communications, said Boulder is taking conservation efforts, which typically ask people to use less energy, in a different direction.
"What we're trying to do is shift to renewable and clean electricity, away from fossil fuels that have harmful greenhouse gas emissions and toward cleaner renewable sources that we actually could use in abundance, if we have been able to make this transformation," she explained.
Like many cities, 99 percent of Boulder's emissions currently come from burning fossil fuels for electricity, heat and transportation. The City Council's move includes a two-year planning window to outline how Boulder can reach its goals, including transitioning to a city-owned utility, increasing energy efficiency and boosting renewable production locally.
Colorado got a failing grade for air quality on the most recent report card from the American Lung Association.
While cities are some of the biggest sources of air pollution, Hillary Larson, communications coordinator for the Colorado Sierra Club, said they're also uniquely positioned to make improvements. She said Boulder's move could energize campaigns already underway to convince Denver, Fort Collins and Pueblo to make similar commitments.
"When cities like Boulder commit to generate 100 percent of their electricity from clean, renewable sources, we know that that is a huge step forward in protecting our health, protecting our air and water, and protecting our planet," Larson said.
Boulder is one of 20 U.S. cities that has officially committed to getting all electricity from renewables, including Aspen, Colo., which reached its goal last year with a combination of hydro-power, wind and increased efficiencies. The State of Hawaii is set to be powered exclusively by clean sources by 2040.

As Coloradans begin to weigh their options in this year's presidential election, a new Carbon Brief analysis projects that a second Biden term would help reduce climate pollution - but the administration will still fall short of meeting its 2030 goals.
Report co-author Simon Evans - senior policy editor at Carbon Brief - said by contrast, a second Trump term that successfully rolls back Biden initiatives, including the Inflation Reduction Act as promised, would add four billion extra tons of fossil fuel pollution.
"That's equivalent to the combined annual emissions of the European Union and Japan," said Evans. "That amount of extra emissions, four billion tons of greenhouse gas emissions by 2030, would cause global climate damage worth something like $900 billion."
Trump has repeatedly claimed that climate change is a hoax, and advanced policies that increased crude oil drilling in order to maintain American energy dominance.
Researchers project a second Trump term would wipe out all emission-reduction gains made over the past five years by installing wind turbines, solar panels, and other clean energy technologies across the globe twice over.
In the 20th century, Evans said nations controlling large fossil fuel reserves did hold significant economic and other advantages.
But in the 21st century and beyond, he said he believes countries with large portfolios of clean energy will have the advantage.
"Actually, clean energy technologies are a great way of bringing energy security," said Evans. "Because you're not relying on import, you're just relying on the wind and the sun that you have in your own country. And the U.S. is certainly very well endowed with wind and solar resources."
Four billion tons is also equivalent to the combined annual emissions of the world's 140 countries with the smallest carbon footprints.
Evans noted that people who can't afford air conditioning to survive extreme heat, or move away from areas prone to flooding and wildfire, will continue to face the biggest threats.
"The people around the world that are least responsible for climate change," said Evans, "whether that's in the poorest countries in the world, or the poorest people in the richest countries - those tend to be the people that are most exposed to the negative impacts of climate change."

Environmental groups in Virginia are among those looking at how to improve and modernize electrical grid transmission.
Experts said the grid's age and current state aren't conducive to the boom in renewable energy projects being developed. The lack of preparation is being felt all over the country but particularly in Virginia, where the latest report card gives the state's grid operator the lowest score.
Quentin Scott, federal policy director for the Chesapeake Climate Action Network, said grid operators' long-term planning needs to consider increasing renewable energy.
"They don't really account for high usage of renewables," Scott pointed out. "They're not accounting for the popularity of the Inflation Reduction Act. They're not accounting for state policies that require states to be 100% clean energy by 2050 or 2040."
Other experts feel grid operators like Virginia's PJM Interconnections need to hire more people to deal with interconnection requests. But increased demand for those jobs makes it harder to address the problem. Virginia's General Assembly passed House Bill 862 to make the process more efficient.
If grid operators cannot make the changes in time, around 80% of the emissions reductions outlined in the Inflation Reduction Act might not happen. Scott and other environmental advocates are worried about losing ground. Along with the Federal Energy Regulatory Commission being a backstop authority for such projects, he noted microgrids can help improve the grid's efficiency.
"Solar panels that are on your roof or community solar projects; small businesses that erect you know, a wind turbine near their business," Scott explained. "Microgrids allow those sort of localized communities to have more planning, more control over their local resources."
Microgrids are also known to be weather resilient. Given the strong effects climate change is having on states' electrical infrastructure, it can be prudent to prevent blackouts. Research has shown if Texas had more connections with the Southeastern U.S., there would not have been as many power outages during the deadly 2021 winter storm.

The first satellite launched by a nonprofit organization is now circling the globe, getting ready to deliver data on methane pollution from oil and gas facilities worldwide.
The MethaneSAT satellite backed by the Environmental Defense Fund will help track methane emissions, a major contributor to global warming.
Jon Goldstein, senior director of regulatory and legislative affairs for the fund, said the advocacy group is focused on making the data transparent, accessible to anyone, and actionable.
"It's going to help the government, it's going to help industry, and it's going to help communities that want to know, 'What's going on in my backyard?'" Goldstein explained. "They'll have this publicly accessible, online data source."
Goldstein emphasized data collected should provide accountability from the more than 50 oil and gas companies that pledged at last year's Dubai "COP-28" climate summit to "zero-out" methane and eliminate routine gas flaring.
Last week, the Environmental Protection Agency published new methane regulations adopted in 2023. New Mexico adopted its own rules in 2021 to crack down on leaks, particularly from smaller facilities.
The new satellite is designed to measure known sources of methane and discover and quantify previously unknown sources. Goldstein noted it would allow companies and countries to take action sooner to help reverse the Earth's rising surface temperature.
"It is a very powerful greenhouse gas; more than 80 times more powerful, pound-for-pound, than carbon dioxide at driving climate change," Goldstein outlined. "That makes it a huge opportunity for folks that want to address this problem quickly, to get out there and get these leaks fixed."
New Mexico is second only to Texas as the largest oil-producing state in the U.S. MethaneSAT was launched last week from California's Vandenberg Air Force Base.
