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 →
Solar, wind, electric vehicles, and other clean energy technologies saw a record-high $1.1 trillion in investment globally last year, matching investment in fossil fuels for the first time ever, according to a new report from Bloomberg New Energy Finance. 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:
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.

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:
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.

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:

Nature gets disrupted even by the most sensitively planned green solutions. Here is a parallel story to yesterday’s, with solar replacing wind and England replacing Western USA, illustrating the challenges facing renewable energy:
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 →
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.

From the ground, the new solar farm shimmers like a mirage oasis on a hot summer day. Instead of row after slanting row of shiny panels stretching taller than corn, this array, mounted directly on the earth, lies flat as water. Continue reading →
Companies like BlueWave are betting on it. But the technology has its critics.

In its 150-year history, Paul Knowlton’s farm in Grafton, Mass., has produced vegetables, dairy products and, most recently, hay. The evolution of the farm’s use turned on changing markets and a variable climate. Recently, however, Mr. Knowlton added a new type of cash crop: solar power. Continue reading →

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%.

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 →

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:
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
Along a dirt-covered road deep in Texas farm country, the cryptocurrency company Argo Blockchain is building a power plant for the internet age: a crypto “mining” site stocked with computers that generate new Bitcoins. Continue reading →
Having won rights to develop wind farms off the coast of Scotland, Shell, Total, and BP are set to invest more in wind power than in oil and gas drilling in the North Sea in the years ahead, the latest evidence of oil majors changing tack on renewables to better navigate the energy transition.

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.

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?

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 →
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.

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.
