Heat Pumps, Circa 2024

/ Organikos / Leave a comment

Heat pumps are energy efficient and considered by many to be powerful tools in combating climate change. Jackie Molloy for The New York Times

The technology is still young, and raising questions, but also full of promise according to this article by Hilary Howard in the New York Times:

Why Heat Pumps Are the Future, and How Your Home Could Use One

The highly efficient devices are the darlings of the environmental movement. Here’s why.

Heat pumps, which both warm and cool buildings and are powered by electricity, have been touted as the answer to curbing greenhouse gas emissions produced by homes, businesses and office buildings, which are responsible for about one-third of the emissions in New York State. Continue reading →

Italy has not figured in our climate change solutions coverage, until now. Our thanks to Stephen Wallis and the New York Times for this:

A Growth Spurt in Green Architecture

Buildings made shaggy with vegetation or fragrant with wood are no longer novelties.

In the lineup of climate villains, architecture towers above many. The building and construction industries account for some 37 percent of worldwide carbon dioxide emissions, according to the United Nations Environment Program. Three of the most commonly used building materials — concrete, steel and aluminum — generate nearly a quarter of all carbon output. Continue reading →

Not exactly manatee charisma, but another ray of sunshine from a place we have been cheering from a distance for a few years now:

Scotland’s Renewable Output More Than 100 Percent of Demand

For the first time, in 2022, Scottish renewables generated more power than the country used, new government figures show.

The growth of wind power, coupled with a small drop in electricity consumption, meant that the volume of electricity produced by renewables in Scotland was equal to 113 percent of demand. Continue reading →

McKibben On The LNG Methane Problem

/ Organikos / Leave a comment

Exporting LNG to China helps no one but frackers

Not as cheerful as Mr. Grouse, but this week’s newsletter is important reading in the interest of progress of this looming LNG problem (a gentle way of putting it, since it is more a PROBLEM than a problem):

Different Kinds of Winning

Helping Biden Help Himself–and the Planet–on Climate

We are, I think, edging towards a win on LNG exports, which would be a very good thing: a pause on the biggest fossil fuel expansion plan on earth. The question, I think, is if it will be the kind of win that makes it easier to boost the beleaguered presidential campaign of Joe Biden—which has got to be a central focus for anyone worried about the planet’s (and our democracy’s) future. And that is largely up to the White House. Continue reading →

Bill McKibben On Degrowth Movements Past & Present

/ Organikos / Leave a comment

Bill McKibben gives a thorough reconsideration of what, if any, growth is helpful now:

To Save the Planet, Should We Really Be Moving Slower?

The degrowth movement makes a comeback.

John Maynard Keynes once observed that dating from “say, to two thousand years before Christ—down to the beginning of the 18th century, there was no very great change in the standard of life of the average man living in the civilised centres of the earth. Ups and downs certainly. Visitations of plague, famine, and war. Golden intervals. But no progressive, violent change.” Continue reading →

Wind Power & Backyard Progress

On previous occasions when we linked to stories about windfarms‘ large turbines, we have noticed that aesthetics can get in the way of progress, so thanks to Stanley Reed and Ivan Penn for this reporting from the New England coast:

A Giant Wind Farm Is Taking Root Off Massachusetts

The offshore energy project will have turbines taller than any building in Boston, but they will be barely visible from Martha’s Vineyard.

On a chilly June day, with the Massachusetts island of Martha’s Vineyard just over the distant horizon, a low-riding, green-hulled vessel finished hammering a steel column nearly 100 feet into the bottom of the Atlantic Ocean. Continue reading →

Developing Clean Energy At Ambitious Scale

/ Organikos / Leave a comment

It is not every day that your country is given good odds on an important project of such an ambitious scale.

The Economist’s WOODBINE column has this to say about it:

America’s chance to become a clean-energy superpower

Getting the most ambitious energy and climate laws in American history through Congress was not easy. Now comes the hard part

The future catches you in unexpected places. Drive down Interstate 95, the highway running along America’s Atlantic coast, into south-eastern Georgia and you will find signs and rest stops named after pecans and peaches. Continue reading →

Post-Peak Meat

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:

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:

Solar farm plans refused at highest rate for five years in Great Britain

Exclusive: Projects which would have cut annual electricity bills by £100m turned down

Solar farms are being refused planning permission in Great Britain at the highest rate in five years, analysis has found, with projects which would have cut £100m off annual electricity bills turned down in the past 18 months.

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.

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 →

100% Renewable California Energy Milestone

/ Organikos / Leave a comment

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
