The renewable energy revolution will need renewable storage

The renewable energy revolution will need renewable storage

Matthew Hutson writes: 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…

Energy requirements of a good life are surprisingly low

Energy requirements of a good life are surprisingly low

Anthropocene magazine reports: The average global energy consumption—79 gigajoules per person per year—is sufficient to power a healthy, comfortable life for everyone on the planet, according to a new study. The analysis is part of a growing body of research aimed at figuring out how to achieve climate goals while also providing modern energy resources to those who lack it. The findings suggest that this balance might be easier than expected to strike: the world doesn’t need a massive expansion…

How waste food can reduce our reliance on natural gas

How waste food can reduce our reliance on natural gas

Future Planet reports: At a large industrial facility not far south-west of Ireland’s capital Dublin, one man says old food waste and pig manure can help Europe fight climate change – and reduce its reliance on Russia for energy. Billy Costello explains that decaying organic matter releases biogas, which firms like Green Generation, the one he directs, can collect and purify to produce methane, or biomethane as it’s called when it comes from such sources. It’s an opportunity to find…

A biomass power plant reignites concerns over clean energy and environmental justice

A biomass power plant reignites concerns over clean energy and environmental justice

Inside Climate News reports: A North Carolina power plant that generates electricity from poultry waste and wood chips has touched off a controversy over an operating permit that, if granted, would imperil public health and wellbeing, residents and environmental advocates in the surrounding community say. Since it started operating in Robeson County in 2015, North Carolina Renewable Power’s South Lumberton plant has repeatedly exceeded allowable emissions for carbon monoxide, nitrogen oxide, sulfur dioxide, particulate matter, known as PM2.5, and methane–a…

As Russia’s war on Ukraine disrupts food production, experts question expanding use of cropland for biofuels

As Russia’s war on Ukraine disrupts food production, experts question expanding use of cropland for biofuels

Inside Climate News reports: In the six weeks since Russia invaded Ukraine, the conflict has not only sent energy prices soaring, but has disrupted food production, pushing costs upward and stoking fears of global food shortages. The United Nations has warned of surging food insecurity in countries that depend on wheat from Ukraine, a critical and major breadbasket. Many of them were already teetering on the edge of hunger before the crisis. As these effects of the conflict ripple across…

Will Russia’s war against Ukraine spur Europe to move on green energy?

Will Russia’s war against Ukraine spur Europe to move on green energy?

Paul Hockenos writes: Russian president Vladimir Putin’s invasion of Ukraine is sparking a wide-ranging revamping of energy policy in Europe with a bold new objective: to wean the continent off Russian gas — as rapidly and comprehensively as possible — and accelerate Europe’s green energy transition. In late-night sessions, Europe’s leaders have been drafting a spectrum of crisis strategies not only to pivot to other natural gas suppliers — as the United States, which imports much less gas and oil…

U.S. oil industry uses Ukraine invasion to push for more drilling at home

U.S. oil industry uses Ukraine invasion to push for more drilling at home

The New York Times reports: Russian troops hadn’t yet begun their full-on assault on Ukraine late Wednesday when the rallying cry came from the American oil and gas industry. “As crisis looms in Ukraine, U.S. energy leadership is more important than ever,” the American Petroleum Institute, the powerful industry lobby group, wrote on Twitter with a photo that read: “Let’s unleash American energy. Protect our energy security.” The crux of the industry’s argument is that any effort to restrain drilling…

How we can defeat Putin and other petrostate autocrats

How we can defeat Putin and other petrostate autocrats

Bill McKibben writes: The pictures this morning of Russian tanks rolling across the Ukrainian countryside seemed both surreal – a flashback to a Europe that we’ve seen only in newsreels – and inevitable. It’s been clear for years that Vladimir Putin was both evil and driven and that eventually we might come to a moment like this. One of the worst parts of facing today’s reality is our impotence in its face. Yes, America is imposing sanctions, and yes, that…

Texas is America’s clean energy leader, almost in spite of itself

Texas is America’s clean energy leader, almost in spite of itself

Inside Climate News reports: In the race to build renewable energy projects in 2021, Texas lapped the competition. The state had 7,352 megawatts of new wind, solar and energy storage projects come online during the year, according to a report issued this week by the American Clean Power Association, a trade group. The runner-up, California, brought 2,697 megawatts online. But what got my attention wasn’t Texas’ dominance in 2021. It was that Texas also is the leader when ranking the…

U.S. corn-based ethanol worse for the climate than gasoline, study finds

U.S. corn-based ethanol worse for the climate than gasoline, study finds

Reuters reports: Corn-based ethanol, which for years has been mixed in huge quantities into gasoline sold at U.S. pumps, is likely a much bigger contributor to global warming than straight gasoline, according to a study published Monday. The study, published in the Proceedings of the National Academy of Sciences, contradicts previous research commissioned by the U.S. Department of Agriculture (USDA) showing ethanol and other biofuels to be relatively green. President Joe Biden’s administration is reviewing policies on biofuels as part…

Wood burners emit more particle pollution than traffic, UK data shows

Wood burners emit more particle pollution than traffic, UK data shows

The Guardian reports: Wood burning in homes produces more small particle pollution than all road traffic in the UK, according to revised government data. The new data significantly cuts the estimated proportion of small particle pollution that comes from wood burners from 38% to 17%. But wood burning pollution remains a “major contributor” to particle pollution, another government report said. Road transport is responsible for 13% of particle pollution. The data shows tiny particle pollution, called PM2.5, produced by wood…

Reinventing the electric grid is crucial for solving the climate crisis

Reinventing the electric grid is crucial for solving the climate crisis

Integrating solar panels with farming can provide partial shade for plants. Werner Slocum/NREL By Charles F. Kutscher, University of Colorado Boulder and Jeffrey Logan, University of Colorado Boulder In the summer of 1988, scientist James Hansen testified to Congress that carbon dioxide from burning fossil fuels was dangerously warming the planet. Scientific meetings were held, voluminous reports were written, and national pledges were made, but because fossil fuels were comparatively cheap, little concrete action was taken to reduce carbon emissions….

Coming soon to this coal county in Kentucky: Solar, in a big way

Coming soon to this coal county in Kentucky: Solar, in a big way

The New York Times reports: For a mountain that’s had its top blown off, the old Martiki coal mine is looking especially winsome these days. With its vast stretches of emerald grass dotted with hay bales and ringed with blue-tinged peaks, and the wild horses and cattle that roam there, it looks less like a shuttered strip mine and more like an ad for organic milk. The mountain is poised for another transformation. Hundreds of acres are set to be…

Will nuclear fusion ever power the world?

Will nuclear fusion ever power the world?

Steffi Diem tells Gizmodo: If funding for fusion energy development continues to increase, then yes, fusion will power the world in the future. Since the 1990s, funding for fusion research in the United States has been for the science of fusion, not for the development of an energy source. The rest of the world has a wide portfolio of fusion research as well, and we are all racing to harness the power of fusion. Major recent advances in technology and…

Hopes grow that nuclear fusion is finally for real and could help address climate change

Hopes grow that nuclear fusion is finally for real and could help address climate change

The Boston Globe reports: It’s been compared to everything from a holy grail to fool’s gold: the ultimate solution to clean, readily available energy or an expensive delusion diverting scarce money and brainpower from the urgent needs of rapidly addressing climate change. For decades, scientists have been trying to harness the energy that powers stars, a complex, atomic-level process known as nuclear fusion, which requires heating a plasma fuel to more than 100 million degrees Celsius and finding a way…

How the U.S. lost ground to China in the contest for clean energy

How the U.S. lost ground to China in the contest for clean energy

The New York Times reports: Tom Perriello saw it coming but could do nothing to stop it. André Kapanga too. Despite urgent emails, phone calls and personal pleas, they watched helplessly as a company backed by the Chinese government took ownership from the Americans of one of the world’s largest cobalt mines. It was 2016, and a deal had been struck by the Arizona-based mining giant Freeport-McMoRan to sell the site, located in the Democratic Republic of Congo, which now…
