AI supercharges data center energy use – straining the grid and slowing sustainability efforts

A data center in Ashburn, Va., the heart of so-called Data Center Alley. AP Photo/Ted Shaffrey By Ayse Coskun, Boston University The artificial intelligence boom has had such a profound effect on big tech companies that their energy consumption, and with it their carbon emissions, have surged. The spectacular success of large language models such as ChatGPT has helped fuel this growth in energy demand. At 2.9 watt-hours per ChatGPT request, AI queries require about 10 times the electricity of…

California is showing how a big state can power itself without fossil fuels

California is showing how a big state can power itself without fossil fuels

Bill McKibben writes: Something approaching a miracle has been taking place in California this spring. Beginning in early March, for some portion of almost every day, a combination of solar, wind, geothermal, and hydropower has been producing more than a hundred per cent of the state’s demand for electricity. Some afternoons, solar panels alone have produced more power than the state uses. And, at night, large utility-scale batteries that have been installed during the past few years are often the…

Fossil fuel companies are trying to rig the marketplace

Fossil fuel companies are trying to rig the marketplace

Andrew Dessler writes: Many of us focused on the problem of climate change have been waiting for the day when renewable energy would become cheaper than fossil fuels. Well, we’re there: Solar and wind power are less expensive than oil, gas and coal in many places and are saving our economy billions of dollars. These and other renewable energy sources produced 30 percent of the world’s electricity in 2023, which may also have been the year that greenhouse gas emissions…

U.S. overhauls electric grid to make way for more renewables

U.S. overhauls electric grid to make way for more renewables

Reuters reports: The U.S. Federal Energy Regulatory Commission on Monday approved the first major electric transmission policy update in over a decade that aims to speed up new interregional lines to move more clean energy to meet growing demand amid the explosion of electric vehicles, data centers and artificial intelligence. Approved in a 2-1 vote, the new rule is also the first time the FERC has ever squarely addressed the need for long-term transmission planning, playing a key role in…

A U.S. push to use ethanol as aviation fuel raises major climate concerns

A U.S. push to use ethanol as aviation fuel raises major climate concerns

MIT Technology Review reports: Eliminating carbon pollution from aviation is one of the most challenging parts of the climate puzzle, simply because large commercial airlines are too heavy and need too much power during takeoff for today’s batteries to do the job. But one way that companies and governments are striving to make some progress is through the use of various types of sustainable aviation fuels (SAFs), which are derived from non-petroleum sources and promise to be less polluting than…

How China became the world’s leader on renewable energy

How China became the world’s leader on renewable energy

Isabel Hilton writes: Last November, Chinese climate envoy Xie Zhenhua and U.S. climate envoy John Kerry shook hands on a pledge to triple renewable energy globally by 2030. It was hailed as a welcome revival of climate cooperation between the world’s biggest and second-biggest emitters of greenhouse gases and offered hope that the two veteran climate negotiators had found a way through a blizzard of negative diplomatic exchanges to keep alive the prospects for greater global ambition on tackling climate…

How a solar revolution in farming is depleting the world’s groundwater

How a solar revolution in farming is depleting the world’s groundwater

Fred Pearce writes: There is a solar-powered revolution going on in the fields of India. By 2026, more than 3 million farmers will be raising irrigation water from beneath their fields using solar-powered pumps. With effectively free water available in almost unlimited quantities to grow their crops, their lives could be transformed. Until the water runs out. The desert state of Rajasthan is the Indian pioneer and has more solar pumps than any other. Over the past decade, the government…

Biden administration is said to slow early stage of shift to electric cars

Biden administration is said to slow early stage of shift to electric cars

The New York Times reports: In a concession to automakers and labor unions, the Biden administration intends to relax elements of one of its most ambitious strategies to combat climate change, limits on tailpipe emissions that are designed to get Americans to switch from gas-powered cars to electric vehicles, according to three people familiar with the plan. Instead of essentially requiring automakers to rapidly ramp up sales of electric vehicles over the next few years, the administration would give car…

Biden’s flip-flopping on fossil fuels is bad policy and bad politics

Biden’s flip-flopping on fossil fuels is bad policy and bad politics

The Washington Post reports: As U.S. oil production was soaring to record levels in December, Biden administration officials were at the U.N. Climate Change Conference in Dubai assuring world leaders that the United States would help lead the global transition away from fossil fuels. That dichotomy stood out to Amara Enyia, an activist and policy director for the Movement for Black Lives, who attended the conference, known as COP28. “There’s this dissonance between the commitments that are being made versus…

‘World’s first net zero transatlantic flight’ might not be so green after all

‘World’s first net zero transatlantic flight’ might not be so green after all

Open Democracy reports: Virgin Atlantic and the UK government have been accused of misleading the public over what they claim will be “the world’s first net zero transatlantic flight” ahead of next week’s COP28 summit. The Department for Transport said the flight, scheduled for Tuesday, was “ushering in a new era of guilt-free flying” because it will run entirely on so-called “sustainable aviation fuel” (SAF). But openDemocracy revealed concerns earlier this year that SAF production in the UK may be…

The world’s 280 million electric bikes and mopeds are cutting demand for oil far more than electric cars

The world’s 280 million electric bikes and mopeds are cutting demand for oil far more than electric cars

By Muhammad Rizwan Azhar, Edith Cowan University and Waqas Uzair, Edith Cowan University We hop in the car to get groceries or drop kids at school. But while the car is convenient, these short trips add up in terms of emissions, pollution and petrol cost. Close to half (44%) of all Australian commuter trips are by car – and under 10km. Of Perth’s 4.2 million daily car trips, 2.8 million are for distances of less than 2km. This is common in…

I’m a climate scientist. I’m not screaming into the void anymore

I’m a climate scientist. I’m not screaming into the void anymore

Kate Marvel writes: Two and a half years ago, when I was asked to help write the most authoritative report on climate change in the United States, I hesitated. Did we really need another warning of the dire consequences of climate change in this country? The answer, legally, was yes: Congress mandates that the National Climate Assessment be updated every four years or so. But after four previous assessments and six United Nations reports since 1990, I was skeptical that…

Texas and others create ‘punitive’ barriers to EV transition

Texas and others create ‘punitive’ barriers to EV transition

Politico reports: Electric vehicle drivers in Texas have started to get some bad news in the mail. Starting in September, they’ll have to pay the state an extra $200 each year to register their climate-friendly cars and trucks. And if they want to buy a new EV, that will cost $400 upfront. State lawmakers imposed the new fee on EVs this spring to replace gasoline taxes lost to the switch to battery-powered vehicles. Supporters say it ensures every driver pays…
