We are always on the lookout for more reasons why reducing beef and dairy consumption makes sense:

Brown gold: the great American manure rush begins

The energy industry is turning waste from dairy farms into renewable natural gas – but will it actually reduce emissions?

Have we reached ‘peak meat’? Why one country is trying to limit its number of livestock

On an early August afternoon at Pinnacle Dairy, a farm located near the middle of California’s long Central Valley, 1,300 Jersey cows idle in the shade of open-air barns. Above them whir fans the size of satellites, circulating a breeze as the temperature pushes 100F (38C). Underfoot, a wet layer of feces emits a thick stench that hangs in the air. Just a tad unpleasant, the smell represents a potential goldmine. Continue reading →

I had no reason to bet against Tesla until now, but I did wonder whether it was good for anyone (other than its shareholders) for that one company to dominate its market over the longer term. Now, happily, it looks like the market will do what we need it to do, which is get robust:

For U.S. Companies, the Race for the New EV Battery Is On

Spurred by federal mandates and incentives, U.S. manufacturers are pushing forward with developing new battery technologies for electric vehicles. The holy grail is a battery that is safer, costs less, provides longer driving range, and doesn’t use imported “conflict” minerals.

Sixteen years have passed since engineer Martin Eberhard unveiled his futuristic custom-designed sports car before a crowd of investors, journalists, and potential buyers in a Santa Monica Airport hangar. Continue reading →

Fusion Hoopla

A reason that the breakthrough is causing such hoopla is that it implicitly promises that we could use fusion to run the world in almost its current form. Photograph courtesy Lawrence Livermore National Laboratory

Without the expertise to fully appreciate the science, the hoopla can be overlooked too easily. McKibben’s comment helps clarify:

The Fusion Breakthrough Suggests That Maybe Someday We’ll Have a Second Sun

In the meantime, we need to use the sun we’ve already got.

On Tuesday, the Department of Energy is expected to announce a breakthrough in fusion energy: according to early reports, scientists at the government’s Lawrence Livermore National Laboratory, in California, have succeeded for the first time in making their complex and expensive machinery produce more power than it uses, if only for an instant.

Imposing On Pastoral Beauty To Capture Wind’s Power

/ Crist Inman / Leave a comment

Pinnacle turbines dot the skyline in Keyser, West Virginia, where, according to Andrew Cosner, a twenty-one-year-old technician, some residents remain hostile to the new wind farm: “They say it ruins the landscape and it’s ugly.”

It is to each of us whether we find the view attractive or not, and there was a time when I found large man-made structures an imposition on pastoral beauty.

Smith stands in the nacelle of one of the turbines just before daybreak.

As time passes I find myself drawn more to such a view as that in the photo above as a signal of progress.  It is not because the view is in a place far away from me– on the mountain ridge above where I live there is a row of such turbines and I am constantly gazing at that horizon. Published in the print edition of the November 28, 2022, issue of the New Yorker, with the headline “Blade Runners,” D.T. Max provides some context, but the photos do the heavy lifting:

Wind power is part of our future. Full stop. But it is worth thinking about how the infrastructure for that power will change places of vast beauty and tradition.

This article by Sammy Roth, with photography by Robert Gauthier, is a worthy thought piece on what we gain, what we give up, and who decides how and where wind energy comes to town:

This power line could save California — and forever change the American West

PacifiCorp’s Ekola Flats wind farm has 63 turbines, most of them rated at 4.3 megawatts — almost six times as much power as some of the old steel-lattice wind towers in the California desert outside Palm Springs. (Robert Gauthier / Los Angeles Times)

I know the wind turbine blades aren’t going to kill me. At least, I’m pretty sure.

No matter how many times I watch the slender arms swoop down toward me — packing as much punch as 20 Ford F-150 pickup trucks — it’s hard to shake the feeling they’re going to knock me off my feet. They sweep within a few dozen feet of the ground before launching back toward the heavens, reaching nearly 500 feet above my head — higher than the highest redwood.

They’re eerily quiet, emitting only a low hum. But in the howling wind, the tips could be barreling past at 183 mph. Continue reading →

More Energy on Less Land: The Drive to Shrink Solar’s Footprint

With the push for renewables leading to land-use conflicts, building highly efficient utility-scale solar farms on ever-smaller tracts of land has become a top priority. New approaches range from installing PV arrays that take up less space to growing crops between rows of panels.

The concept of agrivoltaics has been an occasional topic in our pages over the years, most recently as we have prepared to plant thousands of coffee saplings. Ellen Rosen focuses our attention on how the advances in technology, and entrepreneurship in this space, are addressing the challenges:

Can Dual-Use Solar Panels Provide Power and Share Space With Crops?

Companies like BlueWave are betting on it. But the technology has its critics.

Recovery from a long-term addiction to fossil fuels was never going to be easy. Necessary? Yes. But it will still be a long haul even with milestones like this one in the western USA. Thanks to National Public Radio (USA) for this news:

California just ran on 100% renewable energy, but fossil fuels aren’t fading away yet

On a mild Sunday afternoon, California set a historic milestone in the quest for clean energy. The sun was shining, the wind was blowing and on May 8th, the state produced enough renewable electricity to meet 103% of consumer demand. That broke a record set a week earlier of 99.9%.

Thanks to Matthew Hutson for the article in the current edition of the New Yorker titled The Renewable-Energy Revolution Will Need Renewable Storage:

Can gravity, pressure, and other elemental forces save us from becoming a battery-powered civilization?

We need to vastly expand our energy-storage capacity if we’re to avoid climate catastrophe.

The German word Dunkelflaute means “dark doldrums.” It chills the hearts of renewable-energy engineers, who use it to refer to the lulls when solar panels and wind turbines are thwarted by clouds, night, or still air. On a bright, cloudless day, a solar farm can generate prodigious amounts of electricity; when it’s gusty, wind turbines whoosh neighborhoods to life. But at night solar cells do little, and in calm air turbines sit useless. These renewable energy sources stop renewing until the weather, or the planet, turns. Continue reading →

Crypto, Pigs & Possibilities

First thought upon seeing the headline of the story below: when pigs fly. There is plenty of evidence to the contrary. If you read to the end of the story, published in the New York Times (click through to read it in full there), you will understand that some at the cutting edge of crypto want to change the name of what they do to “validators” from the less environmentally-friendly sounding “miners.” So, second thought: lipstick on pigs. But, at least they are acknowledging the complaint. Plus, the author of this story has a remarkable track record of reporting on issues we care about. So let’s read their latest claims with an open mind:

Bitcoin Miners Want to Recast Themselves as Eco-Friendly

Facing intense criticism, the crypto mining industry is trying to change the view that its energy-guzzling computers are harmful to the climate.

Texas has become a hot spot for crypto mining, attracting more than two dozen companies, partly because of an unusual incentive structure with its power grid. Carter Johnston for The New York Times

More Solar Canopy Initiatives

/ Organikos / Leave a comment

Using solar panels to create shade for coffee trees requires thought about the tradeoffs between the non-shade benefits trees otherwise provide: (nitrogen-fixing in the case of poro trees, plus bird habitat and other biodiversity benefits) and the non-shade benefits that solar panels provide (renewable energy). Solar panels on parking lots and other roofs, on the other hand, seems the definition of a no-brainer. Our thanks to Richard Conniff and Yale e360, as always:

Why Putting Solar Canopies on Parking Lots Is a Smart Green Move

Solar farms are proliferating on undeveloped land, often harming ecosystems. But placing solar canopies on large parking lots offers a host of advantages — making use of land that is already cleared, producing electricity close to those who need it, and even shading cars.

Fly into Orlando, Florida, and you may notice a 22-acre solar power array in the shape of Mickey Mouse’s head in a field just west of Disney World. Nearby, Disney also has a 270-acre solar farm of conventional design on former orchard and forest land. Park your car in any of Disney’s 32,000 parking spaces, on the other hand, and you won’t see a canopy overhead generating solar power (or providing shade) — not even if you snag one of the preferred spaces for which visitors pay up to $50 a day.

Global North, Global South & Responsibilities

David Wallace-Wells has done it again. Devastated me with considerations I should have had on my own, but had not. And he makes it so vivid that once you see his point you cannot stop seeing it. Having lived in the Global South for a majority of my adult years, but having been born into and lived in the Global North for the first half of my life, this story resonates with me in ways I cannot quite describe. But the quote from Proverbs in yesterday’s post seems even more intensely relevant:

Climate Reparations

A trillion tons of carbon hangs in the air, put there by the world’s rich, an existential threat to its poor. Can we remove it?

I. What Is Owed

The math is as simple as the moral claim. We know how much carbon has been emitted and by which countries, which means we know who is most responsible and who will suffer most and that they are not the same. We know that the burden imposed on the world’s poorest by its richest is gruesome, that it is growing, and that it represents a climate apartheid demanding reparation — or should know it. We know we can remove some of that carbon from the atmosphere and undo at least some of the damage. We know the cost of doing so using tools we have today. And we know that unless we use them, the problem will never go away. Continue reading →

Wind, of all the alternative energy sources we pay attention to, requires vast areas for generation. So water has become the go-to place to place the turbines. It looks like the new race is whether to have the turbines fixed or floating:

Floating wind turbines could open up vast ocean tracts for renewable power

Technology could help power a clean energy transition if it can overcome hurdles of cost, design and opposition from fishing

In the stormy waters of the North Sea, 15 miles off the coast of Aberdeenshire, in Scotland, five floating offshore wind turbines stretch 574 feet (175 metres) above the water. The world’s first floating windfarm, a 30 megawatt facility run by the Norwegian company Equinor, has only been in operation since 2017 but has already broken UK records for energy output.

Choices For Mining Lithium

/ Organikos / Leave a comment

The Salton Sea is one of numerous new mining proposals in a global gold rush to find new sources of metals and minerals needed for electric cars and renewable energy.

Thanks to the New York Times for this coverage of the choices surrounding how and where to mine a key ingredient of more efficient batteries–a consequential environmental question:

The Lithium Gold Rush: Inside the Race to Power Electric Vehicles

A race is on to produce lithium in the United States, but competing projects are taking very different approaches to extracting the vital raw material. Some might not be very green.

“This is the most sustainable lithium in the world, made in America,” Rod Colwell, the chief executive of Controlled Thermal Resources, said. “Who would have thought it? We’ve got this massive opportunity.”

Atop a long-dormant volcano in northern Nevada, workers are preparing to start blasting and digging out a giant pit that will serve as the first new large-scale lithium mine in the United States in more than a decade — a new domestic supply of an essential ingredient in electric car batteries and renewable energy.

The mine, constructed on leased federal lands, could help address the near total reliance by the United States on foreign sources of lithium.

But the project, known as Lithium Americas, has drawn protests from members of a Native American tribe, ranchers and environmental groups because it is expected to use billions of gallons of precious ground water, potentially contaminating some of it for 300 years, while leaving behind a giant mound of waste.
