California reaches new record clean energy milestone

July 15, 2025

California has hit a new record for clean energy.

Solar, wind, hydropower and other carbon-free sources made up 67% of the state’s retail electricity supply in 2023, the most recent year that data is available, according to new statistics released Monday by the California Energy Commission.

The total is an increase from 2022, when it was 61%. And it exceeds the prior record of 64%, set in 2019.

Under a state law signed by former Gov. Jerry Brown in 2018 aimed at reducing air pollution and greenhouse gas emissions that are contributing to climate change, California is required to reach 100% renewable and carbon-free electricity by 2045.

Solar, wind, geothermal, large hydropower, biomass and nuclear energy are allowed to count under the law.

The new milestone comes as renewable energy is facing several headwinds. Earlier this month, Republicans in Congress passed and President Trump signed a bill that removes and reduces many of the tax breaks, federal grants and other incentives that were put in place by President Biden for states, private companies and homeowners to expand renewable energy and electric vehicles.

Op-Ed: Looking locally for renewable energy

As the new federal administration’s policies begin to unfold, it’s clear that real climate solutions will primarily be driven at the local level. It’s also clear that shifting from fossil fuels toward renewable electricity is made more difficult in California because of our sky-high electric rates. Community-owned power providers like Sonoma Clean Power are tackling both challenges — climate change and cost.

One way Sonoma Clean Power works to keep electric bills in check is by advocating at the California Public Utilities Commission for more effective wildfire prevention expenditures. We believe PG&E should focus on the most critical repairs first, not the easiest or most lucrative. We also believe PG&E needs to better justify any new rate increases, which is why we’ve started carefully checking their math. By advancing solutions to make rates reasonable, we can help everyone afford the switch to electric appliances and vehicles.

Los Angeles Times columnist Sammy Roth suggested shifting the expense of undergrounding power lines from electric bills to the state’s general fund. Such a move could lower overall costs for both low-income and most middle-income customers, making electric appliances more appealing and helping us reduce fossil fuel use faster. Sonoma Clean Power is studying how to make this approach viable, because affordable rates are essential for speeding up climate progress.

Constellation Energy nears $30 billion deal for Calpine, major player in Geysers geothermal

Constellation Energy Corp. is nearing an acquisition of Calpine Corp., people familiar with the matter said, in what would be one of the biggest ever deals in the power generation sector.

Baltimore-based Constellation is in discussions with Calpine’s private equity owners about the terms of a transaction that could value the company at about $30 billion including debt, according to the people. A deal may be announced in the coming weeks, they said.

Calpine operates the majority of power plants in The Geysers geothermal field straddling Sonoma and Lake counties in the Mayacamas mountains.

Op-Ed: Sonoma County leads on climate policy

December 22, 2024

As world leaders convened at the annual U.N. climate conference in November, scientists reported that carbon dioxide levels in the earth’s atmosphere had reached another record — 423 parts per million, more than 50% higher than preindustrial levels.

As a result, 2023 was the hottest year ever recorded and 2024 in on track to be even hotter. The cause: Humanity’s unabated burning of coal, oil and natural gas has unleashed massive amounts of CO2.

The result is more frequent and intense wildfires, prolonged droughts, hotter heat waves, increasingly destructive hurricanes, deadlier floods, ocean acidification, sea level rise, species extinctions and collapsing fisheries.

According to climate scientists, unless immediate action is taken to rapidly phase out fossil fuels in favor of clean, renewable energy, our worsening climate poses grave threats to human civilization in the decades ahead.

But such critical action is not happening fast enough. Despite Congress having adopted historic climate legislation two years ago, global energy demand is growing faster than clean energy is expanding.

If only the world was following Sonoma County’s lead.

New bill critical to unlocking advancement toward increased geothermal power generation

September 30, 2024

Mary Callahan, PRESS DEMOCRAT

The much-anticipated statute is the key to unlocking expanded development of clean, renewable geothermal energy in and around The Geysers, officials say.

An obscure state bill signed by Gov. Gavin Newsom last week could not seem less important. Or interesting.

Let’s be honest.

It describes how counties can now serve as lead agencies for environmental review of geothermal exploratory projects in California. Yawn.

But local officials say the much-anticipated statute is the key to unlocking expanded development of clean, renewable geothermal energy in and around The Geysers, advancing green energy goals here and across the West through more efficient and sustainable next-gen technologies that could be incubated here.

At stake is the chance for Sonoma Clean Power, the majority electrical supplier in Sonoma and Mendocino counties, to phase out remaining dependence on aged, highly polluting natural gas power plants that plug the supply gap when nightfall and unsuitable weather reduce availability of solar and wind power.

New geothermal energy approaches proposed for use in the Sonoma, Lake and Mendocino region could ensure a round-the-clock supply of renewable, 100% emission-free power for local consumers and for folks outside the area in the future, as well.

US overhauls electric grid to make way for more renewables

The U.S. Federal Energy Regulatory Commission on Monday approved the first major electric transmission policy update in over a decade that aims to speed up new interregional lines to move more clean energy to meet growing demand amid the explosion of electric vehicles, data centers and artificial intelligence.

Approved in a 2-1 vote, the new rule is also the first time the FERC has ever squarely addressed the need for long-term transmission planning, playing a key role in helping meet the Biden administration’s goal of decarbonizing the economy by 2050 and making the grid more resilient to more frequent climate-fueled extreme weather events.

“This rule cannot come fast enough,” FERC Chairman Willie Phillips, who voted for the final rule. “There is an urgent need to act to ensure the reliability and the affordability of our grid.”

“We are at a transformational moment for the electric grid with phenomenal load growth,” he added, citing the surge in domestic manufacturing, proliferation of data centers, and the surge in extreme weather events that have pushed the country’s ageing infrastructure to its limits.

FERC has been working for nearly two years on the rule to reform how new electric transmission gets approved and paid for, with new requirements for moving electricity across states and covering the costs of new projects.

California reduces payments for rooftop solar power — for second time in a year

November 16, 2023

Ben Christopher and Julie Cart, CALMATTERS

The utilities commission reduced payments to apartments, schools and businesses selling solar power to the grid despite a barrage of criticism. Commissioners say it reverses unfair subsidies.

After months of debate and two postponed votes, California’s utility regulator unanimously voted today to overhaul incentives for owners of apartment buildings, schools and businesses that install solar panels.

The new regulations are the second major step that the California Public Utilities Commission has taken in the past year to reduce power companies’ financial support for rooftop solar. In December, the commission reduced payments to homeowners who sell excess power from newly installed solar panels on single-family homes.

Still, for solar advocates, it could have been worse.

Thanks to a last-minute regulatory tweak, the new rules today stop short of a previous proposal that solar industry groups and housing-related interests warned would result in the “evisceration” of the multifamily solar market.
