Two electric buses arrived in Santa Rosa on Wednesday morning and two more are on the way as the city is poised to put them into service later this year — the start of a bigger shift to eliminate carbon emissions tied to the CityBus fleet.

The switch to electrical buses is part of the city’s initiative to make public transportation fully zero-emission by 2030 and drastically lower carbon emissions in the transportation sector, which accounts for 60% of climate warming gases in the county.

The city’s all-electric buses, which cost $1.2 million each, join three currently in the county fleet, and are part of the broader plan by transit and fleet managers eyeing a transition away from fossil fuel vehicles over the coming years.

Sonoma County Transit introduced its first electric bus in 2018 and plans to add three more by the end of this year, with up to 19 in service by mid-2024, said Sonoma County Transit Systems Manager Bryan Albee said.

Op Ed: California can do better than carbon neutrality by 2045

May 22, 2022

Daniel Kammen, THE PRESS DEMOCRAT

Ten years ago, many Californians could not have imagined the climate nightmare we are living today — dark orange skies during wildfire season, heat waves in the dead of winter, mandatory water restrictions amid crippling drought.

Without urgent action, we may well look back on this moment as the calm before the storm. Over the course of the next decade, California’s biggest climate challenges — hotter summers, a shorter rainy season and more destructive wildfires — could double in intensity.

It’s against this backdrop that the California Air Resources Board last week released a draft of our state’s scoping plan, a blueprint for combating climate change that will guide California’s policy for years. Despite the stakes for Californians, and although my research indicates the state could actually become carbon negative by 2030, the draft proposal would delay reaching carbon neutral until 2045. The barriers to a target of 2030 are political, not technical.

The draft plan calls for investment in new fossil fuel electricity resources, and it relies on unproven and costly carbon capture technologies that would lock in fossil fuel pollution. Adopting this approach would be lazy, nonsensical and racially unjust. During the current 45-day period for public review of the plan, California has the chance to choose a smarter path.

Renewable energy, even when coupled with energy storage, is cheaper than fossil fuels. California’s own state laws say that renewable energy must be prioritized before building out expensive and polluting gas power plants. Instead, California must set ambitious targets that immediately cut pollution through no-regrets strategies.

Biden administration announces new funding to make homes energy-efficient

May 2, 2022

Anna Phillips, WASHINGTON POST

A decades-old home weatherization program has become central to the administration’s plans to cut Americans’ power bills and lower fossil fuel emissions

Amid surging inflation and energy price spikes, the Biden administration on Wednesday announced plans to spend roughly $3.2 billion to retrofit hundreds of thousands of homes in low-income communities with the aim of slashing Americans’ energy bills and greenhouse gas emissions.

The new funding from the $1.2 trillion infrastructure bill President Biden signed into law last year provides a massive boost to a federal home weatherization program that began during the 1970s oil crisis as a way to cut people’s heating bills. It allots funding to modernize eligible homes with cost-effective upgrades, adding insulation to attics, swapping older refrigerators and other appliances for new, more efficient models, and replacing leaky windows and doors.

Biden officials said the infusion of funding — a tenfold increase compared to the program’s current budget — means it will be able to serve 450,000 households total. It currently retrofits about 38,000 homes a year.

Straus Family Creamery puts Sonoma County dairy cows on seaweed diet to test method to fight climate change

December 14, 2021

Susan Wood, NORTH BAY BUSINESS JOURNAL

Straus Family Creamery is widely known for all things food, but red seaweed isn’t one of them — until now.

This summer, ecologist-at-heart Albert Straus, who is a pioneer in organic farming, signed up his 24 cows on his Petaluma farm to help determine if feeding them red seaweed would reduce their methane emissions, mostly from belching. He mixed the ocean plant into their feed, like humans would add green onions to their scrambled eggs,

And over a 50-day trial in which the cows were tested four times a day, methane releases dropped by 52%. In some circumstances, the experiment showed the methane was cut by as much as 90%. Straus, who produces an assortment of mass-produced dairy products, believes a second trial planned in January will produce more consistent results.

“We know we can do better than that,” he told the Business Journal, referencing the lower percentage of reduction.

So far in the first trial, the equivalent of five metric tons of harmful greenhouse gases, blamed in causing the planet to heat up, was cut.

As part of a state climate initiative, California’s 2030 mandate requires a reduction of methane by 40%. It has been determined that cow burps are responsible for 35% of total U.S. on-farm greenhouse gas emissions.

Why I was wrong about methane

June 17, 2021

Dan Farber, LEGAL PLANET

I didn’t think cutting methane was a high priority. Now I do. Here’s why.

I didn’t use to think that eliminating methane emissions should be a priority. True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. In contrast, CO2 emissions cause warming for 2-3 centuries or more. So methane emissions seemed to be something that could be addressed at any point we got around to them. I’ve rethought that conclusion, however for a combination of policy and political economy reasons.

On the policy side, cutting methane would have immediate benefits that aren’t limited to reducing warming. Because methane contributes to ozone pollution, emissions cause immediate health effects as well as warming effects. According to the U.N., “a 45 per cent reduction would prevent 260 000 premature deaths, 775 000 asthma-related hospital visits, 73 billion hours of lost labour from extreme heat, and 25 million tonnes of crop losses annually.”.

In addition, one reason to worry about methane is that it accelerates warming, even if the world would have eventually gotten to the same temperature due to CO2 emissions. The pace of warming matters, not just the extent of warming. A pulse of methane today may not matter in a century, but it does mean that warming over the next few decades will happen faster. Slower warming gives the world less time to adopt adaptation measures like strengthening flood defenses, making crops more drought resistance, taking precautions against heat waves. . Before we can take those steps, institutions and public attitudes will themselves have to adapt to the realities of climate change. If we can slow warming a bit, even if we end up in the same place ultimately due to carbon emissions, that gives us more time to prepare for what’s coming down the road.

Biden administration to propose first rule requiring cut in climate pollutants

May 3, 2021

Juliet Eilperin and Dino Grandoni, THE WASHINGTON POST

The new Environmental Protection Agency rule targets hydrofluorocarbons, greenhouse gases that are thousands of times more powerful than carbon dioxide.

The Environmental Protection Agency proposed a rule Monday to slash the use and production of a class of powerful greenhouse gases used widely in refrigeration and air conditioning in the next decade and a half. The proposal marks the first time President Biden’s administration has used the power of the federal government to mandate a cut in climate pollution.

Unlike many of the administration’s other climate initiatives, there’s broad bipartisan support for curbing hydrofluorocarbons, pollutants thousands of times more potent than carbon dioxide at warming the planet. Congress agreed at the end of last year to slash the super-pollutants by 85 percent by 2036 as part of a broader omnibus bill.

A global phasedown of hydrofluorocarbons, also known as HFCs, is projected to avert up to 0.5 degree Celsius (0.9 degrees Fahrenheit) of warming by the end of the century.

Widely used in refrigeration, as well as residential and commercial air conditioning and heat pumps, HFCs were developed as a substitute for chemicals that depleted the Earth’s protective ozone layer. But their heat-trapping properties have helped increase temperatures.

Healdsburg debuts biggest floating solar farm in nation

March 10, 2021

Andrew Graham, THE PRESS DEMOCRAT

Over the last four months, two ponds at Healdsburg’s wastewater treatment plant were transformed by workers assembling rows of solar panels and pushing them out one by one to float gently on the water’s surface.

The project covered roughly half the combined 15 acres of ponds with 11,600 panels. It is likely the largest floating solar farm in the United States, the builders said, and will provide 8% of the city’s annual electrical needs.

The farm puts Healdsburg’s municipal power utility, itself a unique electricity model in the county, at the cutting edge of solar energy development. Floating solar farms are quickly gaining popularity in the U.S., backers say, particularly in places like Sonoma County where the price of land is dear.

“You couldn’t go out and buy a bunch of vineyard land for a solar project and make it economical,” Healdsburg utilities director Terry Crowley said. Floating solar farms are cost effective as the price of solar panels continues to drop, and are easy to build, Crowley said. Workers began assembling this one in mid-October and mostly finished by mid-January.

“It’s just new to California,” he said.

Windsor two years ago deployed a smaller floating solar installation to power its wastewater treatment plant. The new Healdsburg project is set to provide enough power to cover the annual supply of roughly 1,120 households.

The two-sided panels capture the sun’s energy as it strikes them from above, and also from below when sunlight reflects off the water. Metal cables anchor the floating farm to the ponds’ banks, while floating walkways give technicians and wastewater treatment plant workers the ability to check the panels.
