The Church of England’s drive to reach net-zero carbon emissions by 2030 is already reducing energy bills and making churches fit for the future, the lead bishop for the environment says.

Speaking to a gathering of diocesan environment officers at the British Antarctic Survey, in Cambridge, the Bishop of Norwich, the Rt Revd Graham Usher, said that acting to tackle the climate and nature crises was a sign of Christian compassion, and “the right thing to do”.

“There is a link here through compassion with Anglicans — with all people around the world — many of whom are on the front line of climate change and biodiversity loss,” he said. “If we truly believe that we are brothers and sisters in Christ, we should have a concern and a compassion for where biodiversity and climate-change loss is impacting people’s lives.”

Americans have long equated energy security with oil. The country wanted as much as possible because of the havoc an interruption to supply—from wars, disasters and political convulsions—can cause.

In coming years, though, energy security will mean electricity.

Power demand, stagnant for decades, is now growing rapidly, for data centers to run artificial intelligence and other digital services and, in time, transportation and buildings.

An economy dependent on electricity will be different from one dependent on oil. It will require mammoth investment in generation, distribution and transmission. It will challenge regulators and political leaders, as the supply and price of electricity become as politically potent as that of gasoline. The country wanted as much as possible because of the havoc an interruption to supply—from wars, disasters and political convulsions—can cause.

US electricity consumption is rising faster than it has in decades, thanks in part to the boom in data center development, the resurgence in manufacturing, and the increasing popularity of electric vehicles. 

Accommodating that growth will require building wind turbines, solar farms, and other power plants faster than we ever have before—and expanding the network of wires needed to connect those facilities to the grid.

But one major problem is that it’s expensive and slow to secure permits for new transmission lines and build them across the country. This challenge has created one of the biggest obstacles to getting more electricity generation online, reducing investment in new power plants and stranding others in years-long “interconnection queues” while they wait to join the grid.

Fortunately, there are some shortcuts that could expand the capacity of the existing system without requiring completely new infrastructure: a suite of hardware and software tools known as advanced transmission technologies (ATTs), which can increase both the capacity and the efficiency of the power sector.

ATTs have the potential to radically reduce timelines for grid upgrades, avoid tricky permitting issues, and yield billions in annual savings for US consumers.

And people are connecting with it. An open day to launch the potting shed brought 17 adults and 27 children together. “It was hard to get rid of them at the end,” Kay joked. “It is changing things for small numbers of people,” she added.

“What I’m seeing is people wanting to be part of what we do,” she said. “People are trying different foods grown in the garden, learning how – and what – to recycle in the church’s recycling bins, and crucially, learning where food comes from, helping to reduce their food bills.”

If investment in data centres is about to slow, nobody told Mark Zuckerberg. On January 29th, during an earnings call, Meta’s boss boasted that the social-media giant had plans to build an artificial-intelligence (AI) data centre “so big that it’ll cover a significant part of Manhattan if it were placed there”.

His timing was conspicuous. Only two days earlier the share prices of firms from Nvidia, a chipmaker, to Dell, a manufacturer of servers used in data centres, had nosedived in response to the release of a new AI model created by DeepSeek, a Chinese firm. Its training costs were a fraction of those for similarly powerful Western models, raising questions over how much computing power—and investment—is needed to develop ai systems.

Although many of those share prices have since recovered, the episode has brought increased scrutiny to the huge sums of money that are being spent on data centres. Meta and America’s three big cloud-service providers—Alphabet, Amazon and Microsoft—forked out a combined $180bn on data-centre infrastructure last year. Add in spending by smaller tech firms, telecoms providers, big enterprises and data-centre operators such as Digital Realty and Equinix, and the figure rises to around $465bn. Land, buildings and peripheral gear such as electrical equipment make up about 30% of that, with chips, server racks, networking kit and the like accounting for the rest. Cashed-up private-equity firms such as Blackstone have been lured in by the spending boom, undertaking a record $70bn-worth of data-centre deals last year.

A key determinant of becoming a global leader in AI is the ability to build an efficient, sustainable and resilient infrastructure that ensures energy is available, reliable and constant. The state of national power grids in China, the EU, and the US remains a significant barrier. China’s creaking grid represents a major constraint to progress and the government is planning to invest more than US$800bn over the next six years. The investment will support Beijing’s Eastern Data, Western Computing initiative, which aims to tap into China’s energy resources in the west and transfer computing power to economic hubs along the coast.

The European power grid is one of the oldest in the world. Moreover, around 40% of the grid is around ten years off its expected lifespan, while over half of the physical grid needs to be repaired or replaced. It remains uncertain whether the estimated US$584bn in European grid investments needed this decade will materialise. In 2024, the EU’s Modernisation Fund handed out almost US$3bn to modernise member states’ energy systems, amongst other activities.

The ageing and fragmented US grid comprises three main regions (Western, Eastern and Texas), which remain inefficient, especially for interconnections between regions. The US Department of Energy (DoE) estimates that power outages cost the US economy US$150bn annually. Modernising the US grid will cost trillions over the coming decades.

Q1: What is the status of global agrobiodiversity?

A1: Today, biodiversity is being lost faster than at any time on record. Since the turn of the twentieth century, the average abundance of terrestrial native species has declined by at least 20 percent across most ecosystems around the world, while the number of crop varieties grown on farms has fallen by more than 90 percent over the last 100 years. Paradoxically, it is the agrifood system itself that is the primary driver of the ecological disruption and degradation imperiling agrobiodiversity around the world.

The environmental impacts of modern food production are myriad. About half of all habitable land on Earth is used for agriculture, while agricultural practices and other human activities have degraded up to 40 percent of the world’s land. Some industrial agriculture has led to the overexploitation of resources that drives habitat loss, the decline in the number of crop species and erosion of crop genetic diversity, and the introduction of invasive species and pollutants—all of which disrupt fragile ecosystems.

In this context, agriculture faces the opposing challenges of increasing food production to meet the needs of a growing global population, while reducing its ecological footprint to ensure that natural resources required for productive agriculture are sustained. In the absence of policies that safeguard agrobiodiversity, efforts to meet food demands threaten to erode the foundation of food production itself.

Agriculture is increasingly strained by growing food demand, global conflict, and the loss of its most foundational resource, agrobiodiversity. This loss threatens not just food security, but global security writ large.

As countries around the world continue to pump planet-warming pollution into the skies, driving global temperatures to record levels, the financial world is racing to fund the emerging field of carbon dioxide removal, seeking both an environmental miracle and a financial windfall.

The technology, which did not exist until a few years ago, is still unproven at scale. Yet, it has a uniquely alluring appeal. Stripping away some of the carbon dioxide that is heating up the world makes intuitive sense. And with a small but growing number of companies willing to pay for it, investors are jockeying to be first movers in what they believe will inevitably be a big industry that is necessary to help fight global warming.

Companies working on ways to pull carbon dioxide from the air have raised more than $5 billion since 2018, according to the investment bank Jefferies. Before that, there were almost no such investments.

“It’s the single greatest opportunity I’ve seen in 20 years of doing venture capital,” said Damien Steel, the chief executive of Canada-based Deep Sky, which has raised more than $50 million to develop carbon dioxide removal projects. “The tailwinds behind the industry are greater than most industries I’ve ever looked at.”

Ukraine is not only the breadbasket of Europe; it is also a mineral superpower, with some of the largest reserves of 117 of the 120 most widely used minerals in the world.

Of the 50 strategic minerals identified by the United States as critical to its economy and national security, many of which are quite rare yet key to certain high-value applications, Ukraine supplies 22.

Ukraine possesses the largest reserves of uranium in Europe; the second-largest reserves of iron ore, titanium and manganese; and the third-largest reserves of shale gas — as well as large deposits of lithium, graphite and rare earth metals, according to a 2022 report by the Canadian geopolitical risk-analysis firm SecDev. These minerals are essential to the production of vital goods ranging from airplanes, cellphones and electric vehicles to steel and nuclear power.

The question for the president-elect is: Does he want Russia and China to get that treasure trove of natural resources? Or does he want to develop them with Ukraine to the benefit of the American people? One of the main reasons Russian President Vladimir Putin invaded Ukraine (aside from his delusional historical fantasies about how Ukrainians and Russians are “one people”) was to seize these natural resources, which are valued at an estimated $26 trillion, according to SecDev.

A sponge made of cotton and squid bone that has absorbed about 99.9% of microplastics in water samples in China could provide an elusive answer to ubiquitous microplastic pollution in water across the globe, a new report suggests.

Just as importantly, the filter’s production appears to be scalable, the University of Wuhan study authors said in the paper, which was peer-reviewed and published in the journal Science Advances. That would address a problem that has stymied the use of previous microplastic filtration systems that were successful in controlled settings, but could not be scaled up.

If it is successfully deployed on a larger scale in forthcoming research, the filter could change the course of one of the world’s most serious public health crises.

“Microplastic remediation in aquatic bodies is essential for the entire ecosystem, but is challenging to achieve with a universal and efficient strategy,” the study’ authors wrote in the paper.

From the American West to eastern China, more than three-quarters of Earth’s land became persistently drier in recent decades, according to a new United Nations report that called the shift a “global, existential peril.”

Industrial emissions of planet-warming gases were a major culprit, the report said. If nations don’t stop the rise in temperatures, the drying is likely to expose more places to sand and dust storms, wildfires, water shortages, crop failures and desertification.

The report was released on Monday at a U.N. summit taking place this month in Riyadh, Saudi Arabia, where nations are discussing how to stop more habitable surfaces from turning into barren wastelands.

Nearly one in three people live in moisture-deprived areas, up from one in five in 1990, the report said.

WSJ When Muhammad Imtiaz received an electricity bill of over $120 last summer, he panicked. The bill, for June and July, was all he earns in a month of ferrying passengers on his motorbike in the scrappy suburbs outside Pakistan’s capital Islamabad.

In his two-room home, where he lives with his wife and four children, he only has a fridge and lights. He runs two fans in the summer months when heat can exceed 110 degrees Fahrenheit.

“Should I give my rent, pay the electricity bill, or buy food for my children?” said Imtiaz, who has racked up $3,000 in debt. His family has one meal a day: watered-down lentils with flatbread. A decade ago, Pakistan, cripplingly short of power, turned to Beijing to build more than a dozen coal, solar and hydroelectric power plants as part of China’s huge infrastructure push in the country.

Now a series of policy mistakes by Islamabad means that Pakistan has enough electricity and more—but, due to the huge debt owed to China, few can afford it. The crisis is overwhelming Pakistan’s fragile economy, throwing millions of households into misery, shredding government finances and shutting down industry.

If all our fear and uncertainty over climate change could be distilled into a single statistic, then arguably it was delivered to an emergency summit on the future of the Antarctic last month.

Nerilie Abram at the Australian National University, Canberra, opened her presentation with a slide headlined “Antarctic sea ice has declined precipitously since 2014, and in July 2023 exceeded a minus 7 sigma event”….As Abram’s slide sunk in, it was as if the whole room was holding its breath. Put simply, a minus 7 sigma event, meaning seven standard deviations below the average, should be all but impossible, says Ed Doddridge at the Australian Antarctic Program Partnership, who works with Abram.

It is “actually really hard to convey just how extreme this difference was, how extreme the low sea ice extent was”, he says. One way is to liken it to the concept of a one-in-100-year flood, for example. “If you run those sorts of statistics for Antarctic sea ice last year, you get a number somewhere between one in 7.5 million years and one in 700 billion years,” says Doddridge.

The reason climate change is so difficult to talk about is that bringing up any one issue is like pulling on a thread in a spiderweb: Every other thread in the web vibrates in response. We feel powerless to effect the changes we would like to see when simply meeting the needs of each day feels like an uphill battle. And so, the anxiety builds—until the anxiety itself feels like part of the avalanche threatening to tumble down on us. Is there any hope at all?

The short answer is yes. In fact, I think this is the time for radical hope. I first encountered this term in Jonathan Lear’s excellent book Radical Hope: Ethics in the Face of Cultural Devastation. Lear explores the history of the Crow tribe in the mid-1800s as they responded to the changes brought by western settlement of their territories in Montana.

The key figure in the book is the Crow chieftain Plenty Coups, who spent his life leading his people through those often-traumatic changes with one key insight: The old nomadic way of life chasing the buffalo was inescapably and irretrievably lost. How could his people hope when the very possibility of a meaningful Crow life was being destroyed? They had to learn to live a new way of life. Even their core values, like what it meant to be courageous, had to be re-formed in a culture where traditional warrior acts of courage were illegal.

Radical hope, then, is the hope that is formed when all our previous hopes are gone. Radical hope was the kind God provided the Israelite exiles….

Data centers are the factories of AI, turning energy and data into intelligence. Industry leaders estimate that a few major U.S. technology companies alone are expected to invest more than $600 billion in AI infrastructure, particularly in data centers, between 2023 and 2026. The countries that work with companies to host data centers running AI workloads gain economic, political, and technological advantages and leverage. But data centers also present national security sensitivities, given that they often house high-end, export-controlled semiconductors and governments, businesses, and everyday users send some of their most sensitive information through them. And while the United States is ahead of China in many aspects of AI, especially in software and chip design, America faces significant bottlenecks with data centers.

Data centers are critical for the digital economy and AI. But the data center buildout is hitting a wall. The United States is home to the plurality of the world’s data centers, numbering in the thousands. Yet America’s aging energy grid, which powers those data centers, is under enormous strain from a complex set of factors, including rising electricity demand, delayed infrastructure upgrades, extreme weather events, and the complex transition to renewable energy. Meanwhile, surging data center demands driven by rapidly increasing AI workloads are exacerbating the grid’s vulnerabilities.

It’s not just a question of how those energy needs can be met, but where. When it comes to data centers, the shortage of powered land in the United States—or more specifically, the shortage of powered land with the connectivity required to support large-scale data centers—combined with supply chain challenges and lengthy permitting timelines for new infrastructure—presents a challenge to realizing both the public and private sectors’ AI ambitions.

The Economist has spoken to a range of people with first-hand knowledge of Iran’s oil system. To check and verify what they told us, and flesh out the detail, we then sought information from other sources, including former sanctions officials, Iranian insiders, intelligence professionals and WikiIran, a third-party website soliciting leaks. Our investigation shows that the country has built sprawling shadow financial channels, which run from its oil rigs to the virtual vaults of its central bank. China, Iran’s main buyer, is an architect of this system, and its chief beneficiary. Global banks and financial hubs, often unknowingly, are used as vital cogs. A source familiar with Iran’s books says that, as of July, it had $53bn, €17bn ($19bn) and smaller pots of other currencies lying abroad.

Although enforcement has weakened in recent years, Iran is subject to the broadest sanctions America has imposed on any country. Aimed at forcing Iran to curb its nuclear enrichment and funding of terrorism, they target swathes of its economy, as well as the government. No other country imposes such stringent sanctions, so, in theory, most can deal with Iran. In practice, few do so openly, as America bans its firms not just from trading with Iran, but also with foreigners that knowingly do so. It is especially tough for Iran to receive and move dollars, as every such transaction, almost anywhere in the world, must eventually be cleared by an American bank.

But our report shows that, with patchy enforcement, determination and help from a greedy partner, a country under a de facto global embargo can end up flouting it on a cosmic scale. Many of Iran’s tactics are reminiscent of those a drug cartel would use to market products and recycle proceeds into other dark enterprises, often via seemingly legitimate businesses. Iran’s subterranean oil system is governed by rules as much as by threats. The task is to construct an elaborate charade that will dupe sanctions-enforcers.

“Nuclear Nightmare,” screamed the headline in Time magazine on April 9th 1979. One of the two reactors at a nuclear-power plant at Three Mile Island in Pennsylvania had suffered an accident. The governor ordered an evacuation of all vulnerable people within five miles of the plant as radioactive gas escaped.

In the end, the accident resulted in no injuries or loss of life. Two decades later, The Economist visited the Pennsylvania hinterlands and found the second, unproblematic reactor still running well and enjoying strong local support. It cranked out power until it was mothballed in 2019 owing not to safety concerns but to competition from cheap shale gas.

Now Three Mile Island is coming back from the dead. On September 20th Microsoft, a tech giant, and Constellation Energy, the utility that decommissioned the trouble-free reactor, signed a deal to return it to service. The utility will spend about $1.6bn to restore the plant by 2028. Microsoft will then buy its carbon-free power for the next 20 years.

Officials last week said multiple dams were on the brink, including Tennessee’s Nolichucky Dam and North Carolina’s Walters and Lake Lure dams. People in nearby communities were ordered to evacuate.

Ultimately, the dams held. But the close calls highlighted the stress on the nation’s dams, many of which are more than half a century old and none of which were designed for the higher levels of precipitation brought on by climate change.

Climate optimism is fading. Higher costs, pushback from businesses and consumers, and the slow rollout of technology are delaying the transition from fossil fuels.

Renewable energy is growing faster than expected. But surging demand for power is sucking up much of that additional capacity and forcing utilities to burn fossil fuels, including coal, for longer than expected.

With greenhouse-gas emissions continuing at record levels, scientists expect floods and heat waves to get worse. This year is on track to be the hottest on record.

Researchers at the University of Waterloo have designed an energy-efficient device that produces drinking water from seawater using an evaporation process driven largely by the sun.

Desalination is critical for many coastal and island nations to provide access to fresh water, given water scarcity concerns due to rapid population growth and increasing global water consumption. Roughly 2.2 billion people worldwide have no access to clean water, emphasizing the urgent need for new technologies to generate fresh water, according to the UN World Water Development Report 2024.

Current desalination systems pump seawater through membranes to separate salt from water, but this process is energy-intensive, and salt often accumulates on the device’s surface, obstructing water flow and reducing efficiency. As a result, these systems require frequent maintenance and cannot operate continuously.

To solve this problem, Waterloo researchers drew inspiration from the natural water cycle to create a device that mirrors how trees transport water from roots to leaves. The new technology can continuously desalinate water without the need for major maintenance.

Geothermal energy may be approaching its Mitchell moment. George Mitchell, a scrappy independent oilman, is known as the father of fracking. Nearly three decades ago, he defied Big Oil and the conventional wisdom of his industry by making practical the hitherto uneconomic technique of pumping liquids and sands into the ground to force out gas and oil from shale rock and other tight geological formations. The enormous increase in productivity that resulted, known as the shale revolution, has transformed the global hydrocarbon business.

Now Fervo Energy, another scrappy Texan upstart, is applying such hydraulic fracturing—alongside other techniques borrowed from the petroleum industry—to the sleepy geothermal sector. Should it succeed, it would mean this relatively fringe source of energy could, in time, become a major player in the energy mix.

The motivation behind geothermal energy is to harness Earth’s abundant subsurface heat for useful ends. This is ordinarily done by tapping into underground reservoirs of hot water or steam. As these are only found in limited areas, this greatly limits the potential of conventional geothermal power. In contrast, “enhanced geothermal systems” (EGS), like the one deployed by Fervo, use hydraulic stimulation to create channels in hot rocks just about anywhere. One well pumps in water into those channels, where it is heated naturally to 200°C or higher. Another well then brings that hot water to the surface, where it is used to generate electricity in a turbine….

As work progresses, the network of Demonstrator Churches – representing many different types of community and situations – will share what they have learned more widely with dioceses and parishes so that all Church of England churches can learn from their experiences.

Abi Hiscock, Project and Grants Manager for the Church of England’s Net Zero Demonstrator Churches Project, said: “Ultimately, we want to demonstrate that with the right support and infrastructure, churches from diverse settings and facing a variety of challenges can reach net zero by 2030.

“By the end of this project, we will have over 100 case studies on what to do and when, and what not to do.

One of North America’s largest areas of interconnected glaciers is melting twice as quickly as it did before 2010, a team of scientists said Tuesday, in what they called an “incredibly worrying” sign that land ice in many places could disappear even sooner than previously thought.

The Juneau Ice Field, which sprawls across the Coast Mountains of Alaska and British Columbia, lost 1.4 cubic miles of ice a year between 2010 and 2020, the researchers estimated. That’s a sharp acceleration from the decades before, and even sharper when compared with the mid-20th century or earlier, the scientists said. All told, the ice field has shed a quarter of its volume since the late 18th century, which was part of a period of glacial expansion known as the Little Ice Age.

As societies add more and more planet-warming carbon dioxide to the atmosphere, glaciers in many areas could cross tipping points beyond which their melting speeds up rapidly, said Bethan Davies, a glaciologist at Newcastle University in England who led the new research.

“If we reduce carbon, then we have more hope of retaining these wonderful ice masses,” Dr. Davies said. “The more carbon we put in, the more we risk irreversible, complete removal of them.”

Scientists like [Magdalena] Osburn have shown that, contrary to long-held assumptions, Earth’s interior is not barren. In fact, a majority of the planet’s microbes, perhaps more than 90 percent, may live deep un­derground. These intraterrestrial microbes tend to be quite different from their counterparts on the surface. They are ancient and slow, re­producing infrequently and possibly living for millions of years. They often acquire energy in unusual ways, breathing rock instead of oxy­gen. And they seem capable of weathering geological cataclysms that would annihilate most creatures. Like the many tiny organisms in the ocean and atmosphere, the unique microbes within Earth’s crust do not simply inhabit their surroundings; they transform them. Subsurface microbes carve vast caverns, concentrate minerals and precious metals and regulate the global cycling of carbon and nutrients. Microbes may even have helped construct the continents, literally laying the ground­work for all other terrestrial life.

Like so much about Earth’s earliest history, exactly where and when life first emerged is not definitively known. At some point not long after our planet’s genesis, in some warm, wet pocket with the right chemistry and an adequate flow of free energy — a hot spring, an impact crater, a hydrothermal vent on the ocean floor — bits of Earth rearranged themselves into the first self-replicating entities, which eventually evolved into cells. Evidence from the fossil record and chemical analysis of the oldest rocks ever discovered indicate that microbial life existed at least 3.5 billion years ago and possibly as far back as 4.2 billion years ago.

Among all living creatures, the peculiar microbes that dwell deep within the planet’s crust today may most closely resemble some of the earliest single-celled organisms that ever existed. Collectively, these subsurface microbes make up an estimated 10 to 20 percent of the biomass — that is, all the living matter — on Earth. Yet until the mid-20th century, most scientists did not think subterranean life of any kind was plausible below a few meters.

Oceans help cool down the world. Startups are betting they can tweak the chemistry of seas to make them do even more.

It is a radical idea that has yet to be proven on a commercial scale and causes some to worry about potential risks. But at least a dozen young companies are embarking on the world’s first major projects to get oceans to soak up more carbon dioxide, encouraged by billions of dollars in federal and corporate funding for efforts that remove the greenhouse gas from the atmosphere.

A startup that uses an electrochemical method to remove carbon from seawater is building its first commercial-scale plants in Singapore and Quebec. Removing the carbon boosts the ocean’s ability to soak up more from the atmosphere. The U.S. government recently awarded it and a competitor with a similar approach some of the first federal funding for carbon removal. 

Another startup is set to pour about 9,000 tons of sand mixed with a yellow-green mineral called olivine near the waters off North Carolina’s Outer Banks. When the sand dissolves in water, it triggers a series of chemical reactions that drive carbon removal.

It is 70 years since at&t’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s.
