Millions of people marched against climate crisis over the past two weeks, in some of the largest demonstrations of the millennium. Most people cheered the students who led the rallies – call them the Greta Generation. But now we’ll start to find out if all their earnest protest actually matters.
Two weeks ago we were visiting the southern tip of the Osa Peninsula, one of our long-time favorite places in Costa Rica. This weekend we made a journey to one of the few spots in Costa Rica where we had never been before, the center of the southern tier, bordering this part of Panama. Seth’s visit to Boquete was one made by many visitors to Costa Rica who either for coffee or birding reasons see this cross-border excursion as a must. We made that excursion from San Jose to Boquete 15 years ago as a family, and my recollection of the coffee sampling, including of the geisha varietal before I knew how important that would become, is a highlight.
Las Mellizas is a village created decades ago by the owners of Hacienda La Amistad, which is where Organikos sources its single estate organic coffee. The farm uses bananas and other fruits, plenty of including avocado, to shade the coffee and add value to the farm’s cash crop activity.
I will have more to say when we are back on grid, but for now I share the image at the top, with the widest view I could find on the farm yesterday, sent using a cell phone connection and electricity from the hydro-electric plant that this farm runs on, shown here.

Jacques Leslie, a veteran writer whose specialty in one of the most-used sources of alternative energy makes him a natural for our platform, somehow has never appeared in our pages before. Dams and the rivers they change are a special case of our interest in conservation, and stories about dam removal are worth the read every time. Here is a clear explanation of one river’s history and future related to dams, and the prospects for dam removal–if you have not read one of these stories yet to understand the historic case for dams and their present illogical realities, this may be the one you want to read:
As renewable energy becomes cheaper than hydropower and the presence of dams worsens the plight of salmon, pressure is mounting in the Pacific Northwest to take down four key dams on the lower Snake River that critics say have outlived their usefulness.
North America’s largest Pacific watershed, the Columbia River Basin, is in the midst of an environmental and energy crisis so severe that the most obvious, yet hotly contested, antidote — removal of four dams on the Columbia’s longest tributary, the Snake River — is gaining traction.
The hydropower dams have been controversial since before their completion, between 1962 and 1975, because of their disastrous impact on salmon and the other 137 species that are part of the salmon food chain. Most of the Columbia Basin’s 250-plus dams have played roles in the salmon’s decline, but the four lower Snake River dams are prime targets for removal because their economic value has diminished and their absence would inordinately benefit salmon.

Happy to see our neighbors to the south taking the lead in greening public transportation:
From Colombia to Argentina, major cities in Latin America are starting to adopt electric bus fleets. In a region with the highest use of buses per person globally, officials believe the transition will help meet climate targets, cut fuel costs, and improve air quality.
Medellín will have 65 electric buses in service by the end of the year, making it the second-largest electric bus fleet in Latin America. MARIA GALLUCCI/YALE E360
In Medellín, Colombia, passengers cram aboard a battery-powered bus during the morning commute. Inside, the vehicle is a respite from the crush of cars, taxis, and motorcycles winding through traffic outside. The driver, Robinson López Rivera, steers the bus up a steep ramp, revealing views of hillsides covered with rooftops of tile and tin. The bus dashboard indicates that the batteries are mostly charged, with enough power to last through the evening rush hour.
“It’s a little smoother and more comfortable to drive. And there’s hardly any noise,” López Rivera says from behind the wheel. He gently brakes as a street vendor pushes a fruit cart across the dedicated bus lane. At night, the bus will return to a parking lot by the airport, recharging its 360-kilowatt battery pack while the city sleeps.

The other 77 buses in the city’s bus rapid transit system, called Metroplús, run on natural gas and move about 251,000 passengers daily. Thousands more privately owned coaches and minibuses burn diesel as they traverse the sprawling metropolitan area of 3.7 million people, with older models leaving a trail of sour-smelling smoke. Faced with chronic air pollution and concerns about climate change, Medellín is now trying to move quickly to electrify its entire mass transit network. Continue reading

National Public Radio (USA) shares a story that links forest management techniques in Arizona to fossil fuel use-reduction in Korea:
A huge mechanical claw scoops up several ponderosa pine logs and feeds them into an industrial chipper. Thousands of wood chunks are then blasted into a large shipping container.
“It goes anywhere from one to four to three up to seven small ones can just kind of throw in that little jaws there,” explains Jeff Halbrook, a research associate with Northern Arizona University’s Ecological Restoration Institute. Today he’s overseeing what’s fondly known as the chip-and-ship pilot project about 20 minutes west of Flagstaff.
These trees being fed into the chipper were recently cut from the nearby Coconino National Forest. A crew of six has been working for days to pack the shipping containers as tightly as possible, stuffing each one with about 40,000 pounds of chipped wood. Then another machine hoists the container onto a nearby railcar. In about two weeks, nearly 60 containers will arrive at a port in South Korea. Continue reading

When we think of farming, we know sunlight is important, but too much sun is not normally a good thing. For solar, no such thing as too much sunlight–the more the better. But counterintuitive though it may be, here is a story about overlapping advantages of sunlight for farming and solar energy production:
And the same land can produce loads of food and electricity simultaneously.
Even after a boom in recent years, solar energy delivers less than 2 percent of power generation to the US electrical grid. But if we’re going to avoid the worst impacts of climate change, the sun’s contribution is going to have to ramp up dramatically. Where to put all the solar panels? You might envision vast solar farms stretching across the sun-scorched barren lands of the Southwest. But according to two recent papers—one from Oregon and Utah researchers, another from a team centered at the University of Arizona—a much different kind of landscape makes the most sense for harvesting solar power: the land currently occupied by food farms.
That’s because the technology that drives solar power—photovoltaic (PV) panels made of silicon that convert light photons directly into electricity—works most efficiently under a specific set of conditions. Most important for this power, of course, is abundant sunlight, which is why deserts make tempting sites for solar energy production. But air temperature is important, too. Above the threshold of 78°F, the hotter it gets outside, the less efficient PV panels are at converting sunlight to electricity. And that’s why blazing-hot deserts pose some problems for solar panels. Continue reading

Biogas came to the attention to most of us contributing to this platform while in India. It has remained on our radar as an important, if quaint farmland quirky skunkworks. Thanks to Yale e360 for highlighting its emergence as a scaling alternative to other forms of natural gas:
For decades, small-scale biogas systems have collected methane from landfills, sewage plants, and farms. Now, in Europe and the U.S., the growth of this renewable form of natural gas is taking off as businesses capture large amounts of methane from manure, food waste, and other sources.

In the next few weeks, construction crews will begin building an anaerobic digester on the Goodrich Family Farm in western Vermont that will transform cow manure and locally sourced food waste into renewable natural gas (RNG), to be sent via pipeline to nearby Middlebury College and other customers willing to pay a premium for low-carbon energy.

For the developer, Vanguard Renewables, the project represents both a departure and a strategic bet. The firm already owns and operates five farm-based biogas systems in Massachusetts; each generates electricity on site that is sent to the grid and sold under the state’s net-metering law. The Vermont project, however, is Vanguard’s first foray into producing RNG — biogas that is refined, injected into natural gas pipelines as nearly pure methane, and then burned to make electricity, heat homes, or fuel vehicles.
“Producing RNG for pipeline injection and vehicle fueling is the evolution of where everything is going” in the biogas sector, says John Hanselman, Vanguard’s CEO. Continue reading
Foundations and charities are helping individuals, communities and businesses install solar panels and battery systems in Puerto Rico, with dual goals: to move the island toward renewable energy and allow small towns to be less dependent on the energy grid in case of another disaster. Greg Allen/NPR
Entrepreneurship and innovation are synonymous in many ways, starting with the ability to “think outside the box”. It’s even more inspiring when people put their creative efforts toward helping communities and the environment. Considering solar power in a Caribbean island environment may not seem like such a novel idea, but garnering private sector support for progress so the government can regroup after a natural disaster is a good example of leadership.
Mameyes is a small community of about 1,000 people high in Puerto Rico’s central mountains. But in its own way, it is one of the leaders of Puerto Rico’s energy future.
Francisco Valentin grew up in Mameyes, where he runs a small store. Even before Maria he had big ambitions for his town. After Maria, he knew he wanted his community to run on solar power. And with the help of foundations, charities and the University of Puerto Rico — not the government — he has done that, converting the town’s school, health clinic and several other buildings.
The move to solar was important, Valentin says, because after Maria it took months before power was restored to the area. This makes Mameyes self-sufficient and able to respond to residents’ needs in future disasters. “The whole school is fully solar energy” and can serve as a shelter, he says.
With so much sunlight on tap, solar power has begun to boom in Puerto Rico since the hurricane. Across the island, individuals, communities and businesses are installing solar panels and battery systems. At the Community Foundation of Puerto Rico, Javier Rivera is working on solar systems with 50 mostly rural, underserved communities. His goal is to wire 250 communities for solar over the next few years.
Rivera says that especially after the hurricane, people realized they couldn’t depend on Puerto Rico’s Electric Power Authority. “Many people [didn’t] trust in the PREPA system before the hurricane. It’s not a secret,” he says. “People start to think about trying to find a solution, a long-term solution. And the sun is one of them.”

Such as Kerala historically, and soon to be many more places due to climate change-related water levels rising.

In the current political climate it may sound like howling in the wind, at first, but read on:
Any serious energy transformation will need to harness America’s powerful and creative economic engine.
By Amory B. Lovins and Rushad R. Nanavatty
Mr. Lovins and Mr. Nanavatty work at Rocky Mountain Institute, which is focused on creating a clean, low-carbon energy future.
The best thing to come from the Senate’s floor debate on the Green New Deal late last month may have been these eminently sane remarks, calling on lawmakers of both parties to “move together” in order “to lower emissions, to address the reality of climate change, recognizing that we’ve got an economy we need to keep strong, that we have vulnerable people we need to protect, that we have an environment that we all care about — Republicans and Democrats.”
Who said it? A Republican, Senator Lisa Murkowski of Alaska, who leads the Energy and Natural Resources Committee. “My hope is we get beyond the high-fired rhetoric to practical, pragmatic, bipartisan solutions,” she said on the chamber floor.
The path is there, if our leaders will only choose to take it. In 2011, Reinventing Fire, an energy study by Rocky Mountain Institute, where we work, showed how a business-led transition could triple energy efficiency, quintuple renewables and sustain an American economy 2.6 times larger in 2050 than it was in 2010 with no oil, coal or nuclear energy, and one-third less natural gas. The net cost was $5 trillion less than business-as-usual — or even more valuable if a price was put on carbon emissions.

Millions of Americans lack access to solar energy because they cannot afford the steep upfront costs. Now, more than a dozen states are adopting “community solar” programs that are bringing solar power and lower energy bills to low-income households from New York to California.

Isbel “Izzy” Palans lives in a small cabin nestled among mountain peaks and towering trees in the Colorado Rockies. Her home is often shaded and, during the long winters, buried under heaps of snow. Her monthly utility bills show credits for solar electricity production, but no solar panels are affixed to her roof. Instead, the power comes from a solar array some 60 miles away in a nearby valley.
Last year, the panels nearly slashed her energy bill in half. “I’ve been thrilled,” said Palans, a 76-year-old retired waitress who relies partly on Social Security benefits to make ends meet.

Palans is a subscriber to a 145-kilowatt solar array project run by Holy Cross Energy, a rural utility cooperative. Built with state funding, the program provides solar credits to more than 40 low-income households in western Colorado that otherwise wouldn’t have the financial or technical means to access renewable energy. The venture is just one of a growing number of so-called “community solar” projects across the United States focused on delivering renewable energy — and the cost-savings it can provide — to low-income households, from California to Minnesota to Massachusetts.

How the United States generated electricity from 2001 to 2017. Percentage of power produced from each energy source
America isn’t making electricity the way it did two decades ago: Natural gas has edged out coal as the country’s leading generation source … and renewables like wind and solar have made small yet speedy gains. But, each state has its own story.
Nadja Popovich an explainer of complicated things with visualization techniques that have impressed us so far, now has this.
In Nevada, natural gas surpassed coal as the top source of electricity generation in 2005, earlier than in many other states. Coal’s role in the state’s power mix has continued to decline since then.
We cannot do justice to it, other than suggest you go see it for yourself. A state by state graphic representation of electrical generation methods:
Overall, fossil fuels still dominate electricity generation in the United States. But the shift from coal to natural gas has helped to lower carbon dioxide emissions and other pollution. Last year, coal was the main source of electricity generation for 18 states, down from 32 states in 2001.
Thank you Norway, for demonstrating that we can do better than neutrality:
The country now has a suite of buildings that generate more energy than they use.
The European Union has a target of making all new buildings zero-energy by 2020, but in Norway, carbon neutrality isn’t enough.
A consortium in Oslo made up of architects, engineers, environmentalists, and designers is creating energy-positive buildings in a country with some of the coldest and darkest winters on Earth. “If you can make it in Norway, you can make it anywhere,” says Peter Bernhard, a consultant with Asplan Viak, one of the Powerhouse alliance members.

I was not aware that Elizabeth Kolbert has been writing for Yale e360 for the entire time we have been linking to her New Yorker work on this platform. And then some, because she started publishing there ten years ago. This is her 17th publication for Yale e360 and it can help a layperson understand in a relatively short read whether technology has any chance of accelerating our progress on climate change mitigation:
A U.S. scientific panel reports that technologies that take CO2 out of the atmosphere could be a significant part of a strategy to mitigate global warming. In an e360 interview, Stephen Pacala, the panel’s chairman, discusses how these fast-developing technologies are becoming increasingly viable.
Is there still time to avoid runaway climate change? To a large degree, the answer depends on the feasibility of “negative emissions” — techniques or technologies that suck CO2 out of the air. In the latest report from the Intergovernmental Panel on Climate Change (IPCC), all scenarios for limiting warming to 1.5 degrees Celsius depend on negative emissions technologies, or NETs. Most 2-degree scenarios also rely on negative emissions; many call for removing billions of tons of CO2 per year by mid-century.
Negative Emissions Technologies (NETs) range from low-tech, such as planting more trees, to more high-tech options, such as developing machines to scrub CO2 from the air. NATIONAL ACADEMY OF SCIENCES, 2018
Yet most NETs remain either untested or unproved. To help bridge this gap, the National Academies convened a panel of scientists and asked it to propose a research agenda. The panel considered several possible techniques, ranging from the low-tech — planting more trees — to the high-tech — developing machines to scrub CO2 from the sky. It also looked at a hybrid technology that has become known as bioenergy with carbon capture and storage, or BECCS. The panel recommended several billion dollars be directed to research on NETs. Such technologies, it suggested, ought to be viewed as a “component of the mitigation portfolio,” rather than as a futuristic, last-ditch effort to reduce atmospheric CO2.

Stephen Pacala, a professor of ecology and evolutionary biology at Princeton University, chaired the panel. In an interview with Yale Environment 360, he talks about why NETs are needed, what should be done to advance them, and why he believes that “direct air capture” technologies could come into widespread use within the next decade.

Despite the rapid decline in the cost of solar-energy technology and battery storage, Arizona gets only six per cent of its electricity from solar. Photograph by Joshua Lott / Bloomberg / Getty
Thanks to Carolyn Kormann, making her fifth appearance since early 2016 in our pages, including this recent item that I particularly favored, for the article below that helps us understand what is happening with renewable energy these days in the USA. It is easy to forget, amidst all the noise of a federal government working to deregulate and reduce environmental protection, that important work continues:
In late September, the Heartland Institute, a libertarian think tank that receives donations from fossil-fuel companies, published a blog post titled “California Billionaire’s Renewable Energy Initiative Makes Arizona Ballot.” The billionaire in question was Tom Steyer, whose year-long effort to pass Proposition 127, an amendment to Arizona’s constitution that would require power companies to generate fifty per cent of their electricity from renewable sources by 2030, has faced aggressive opposition from the state’s largest utility, Arizona Public Service, or A.P.S. The blog post lamented a failed lawsuit filed by Arizonans for Affordable Energy, a political-action committee funded by A.P.S.’s parent company, to keep Prop 127 off the ballot, and quoted several opponents who believed the measure, now up for a vote in November, would be a costly mistake. “Prop 127 would tie Arizona’s future to technologies that do not deliver baseload electricity,” Mark Finchem, a Republican state representative, said, “and are arguably worse for the environment as a whole than the dependable technologies we already have.” The photograph accompanying the post depicted a wind-turbine farm, and, in the foreground, a dead bald eagle.
Arizona is the sunniest state in the country, with more than three hundred bluebird days per year. It is also projected to endure an additional month of hundred-degree days in the coming decades owing to climate change. Yet, despite the rapid decline in the cost of solar-energy technology and battery storage—to the point that, as an A.P.S. director told me, it now frequently outbids fossil fuels, even natural gas—in 2017, Arizona generated only six per cent of its electricity from solar, according to the ballot initiative’s advocates. The state currently requires utilities to generate eight per cent of their power from sources like solar and wind, scaling up to fifteen per cent by 2025. Natural gas, the largest source of Arizona’s net electricity generation, is imported from out of state. “Our most abundant resource in Arizona is our sunshine,” D. J. Quinlan, a spokesman for Clean Energy for a Healthy Arizona, the Phoenix-based political-action committee that Steyer is funding, said. “We need a nationwide transition to renewables. One of the first places we should be doing it is where it’s most efficient and cost-effective, and that’s here.” Continue reading

My daily contribution to this platform is a habit vaguely in the tradition of meditation–finding something each day that is worthy of gratitude, or otherwise worthy of sharing with friends, family, and anyone else who cares to listen. Because of the good fortune I have had to visit and work in many amazing places, it is important to me to never regret the places where I still have not been. Scotland is one of those places that, if I were a regretter, I would be feeling it now. I owe that place a visit (even if the company name sounds like a Bond villain):
Carbon trading has featured, or at least been mentioned, only rarely on this platform, now that I stop to check. That seems impossible. But the scheme with so much promise has simply not taken off. Indigenous heritage, on the other hand, has featured in dozens of stories here since we started in 2011. Thanks to Carolyn Kormann for bringing this story to my attention, helped by two captivating photos and the fact that it highlights the approach of the Yurok Tribe (a community I had not heard of before):
“I think we did a good thing by saving the trees, but I’m not happy with it,” Jene McCovey, a tribal elder, said. “It’s not viable. It allows polluters to pollute.” Photograph by Joel Redman
When Marty Lamebear is not fighting fires, he is starting them. In the past few years, as a member of the Yurok Tribe Forestry Program’s fire department, he has been helping revive the controversial practice of prescribed burns to protect and restore the coastal redwood forests of northern California. Lamebear is also a hunter, fisherman, and dancer. In his free time, he makes tribal regalia for ceremonial dances from parts of elk, deer, minks, and porcupines, which he shoots or finds already dead, and from frozen eagles that he orders from the U.S. Fish and Wildlife Service. A prescribed burn, what Lamebear calls a culture burn, creates prairies within the forest, which attract those animals. “At first, we couldn’t really tell its effects,” he said. “But, after about six years now, we can honestly start seeing the landscape open up, animals come around.” They also serve another purpose, he said. “It’s insurance for our carbon.” Continue reading
