The Download: Microsoft’s quantum chip, and explaining rising energy demand

IceLoungeMedia IceLoungeMedia

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

A new Microsoft chip could lead to more stable quantum computers

Microsoft has announced that it’s made significant progress in its 20-year quest to make topological quantum bits, or qubits—a special approach to building quantum computers that could make them more stable and easier to scale up. 

The company says it’s developed a chip containing eight of these qubits, and has also published a Nature paper that describes a fundamental validation of the system. It’s a different approach to competitors like Google and IBM. But, if it works, it could be a significant milestone on the path to unlocking quantum computers’ dramatic new abilities to discover new materials, among many other possible applications. 

Many of the researchers MIT Technology Review spoke with would still like to see how this work plays out in scientific publications, but they were cautiously optimistic. Read the full story.

What’s driving electricity demand? It isn’t just AI and data centers.

Electricity demand rose by 4.3% in 2024 and will continue to grow at close to 4% annually through 2027, according to a new report from the International Energy Agency. 

There’s been a constant stream of headlines about energy demand recently, largely because of the influx of data centers—especially those needed to power AI. These technologies are sucking up more power from the grid, but they’re just a small part of a much larger story. 

What’s actually behind this demand growth is complicated. Read our story to learn what’s going on.

This company is trying to make a biodegradable alternative to spandex

It probably hasn’t been long since you last slipped into something stretchy. From yoga pants to socks, stretch fabrics are everywhere. And they’re only getting more popular: The global spandex market, valued at almost $8 billion in December 2024, is projected to grow between 2% and 8% every year over the next decade. 

That might be better news for your comfort than for the environment. Most stretch fabrics contain petroleum-based fibers that shed microplastics and take centuries to decompose. Alexis Peña and Lauren Blake, cofounders of Good Fibes, aim to tackle this problem with lab-grown elastics. Read the full story.

What’s driving electricity demand? It isn’t just AI and data centers.

Electricity demand rose by 4.3% in 2024 and will continue to grow at close to 4% annually through 2027, according to a new report from the International Energy Agency. 

If that sounds familiar, it may be because there’s been a constant stream of headlines about energy demand recently, largely because of the influx of data centers—especially those needed to power the AI that’s spreading seemingly everywhere. These technologies are sucking up more power from the grid, but they’re just a small part of a much larger story. 

What’s actually behind this demand growth is complicated. Much of the increase comes from China, India, and Southeast Asia. Air-conditioning, electric vehicles, and factories all play a role. And of course, we can’t entirely discount the data centers. Here are a few key things to know about global electricity in 2025, and where things are going next.

China, India, and Southeast Asia are the ones to watch.

Between now and 2027, about 85% of electricity demand growth is expected to come from developing and emerging economies. China is an especially major force, having accounted for over half of global electricity demand growth last year.

The influence of even individual sectors in China is staggering. For example, in 2024, about 300 terawatt-hours’ worth of electricity was used just to produce solar modules, batteries, and electric vehicles. That’s as much electricity as Italy uses in a year. And this sector is growing quickly. 

A boom in heavy industry, an increase in the number of air conditioners, and a robust electric-vehicle market are all adding to China’s power demand. India and Southeast Asia are also going to have above-average increases in demand, driven by economic growth and increased adoption of air conditioners. 

And there’s a lot of growth yet to come, as 600 million people across Africa still don’t have access to reliable electricity.

Data centers are a somewhat minor factor globally, but they can’t be counted out.

According to another IEA projection published last year, data centers are expected to account for less than 10% of global electricity demand growth between now and 2030. That’s less than the expected growth due to other contributors like electric vehicles, air conditioners, and heavy industry.

However, data centers are a major storyline for advanced economies like the US and many countries in Europe. As a group, these nations have largely seen flat or declining electricity demand for the last 15 years, in part because of efficiency improvements. Data centers are reversing that trend.

Take the US, for example. The IEA report points to other research showing that the 10 states hosting the most data center growth saw a 10% increase in electricity demand between 2019 and 2023. Demand in the other 40 states declined by about 3% over the same period.

One caveat here is that nobody knows for sure what’s going to happen with data centers in the future, particularly those needed to run AI. Projections are all over the place, and small changes could drastically alter the amount of energy required for the technology. (See the DeepSeek drama.)

One bit I found interesting here is that China could see data centers emerge as yet another source of growing electricity demand in the future, with demand projected to double between now and 2027 (though, again, it’s all quite uncertain).

What this all means for climate change is complicated.

Growth in electricity demand can be seen as a good thing for our climate. Using a heat pump rather than a natural-gas heating system can help reduce emissions even as it increases electricity use. But as we add demand to the grid, it’s important to remember that in many places, it’s still largely reliant on fossil fuels.

The good news in all this is that there’s enough expansion in renewable and low-emissions electricity sources to cover the growth in demand. The rapid deployment of solar power alone contributes enough energy to cover half the demand growth expected through 2027. Nuclear power is also expected to see new heights soon, with recovery in France, restarts in Japan, and new reactors in China and India adding to a stronger global industry.

However, just adding renewables to meet electricity demand doesn’t automatically pull fossil fuels off the grid; existing coal and natural-gas plants are still chugging along all over the world. To make a dent in emissions, low-carbon sources need to grow fast enough not only to meet new demand, but to replace existing dirtier sources.

It isn’t inherently bad that the grid is growing. More people having air-conditioning and more factories making solar panels are all firmly in the “positive” column, I’d argue. But keeping up with this breakneck pace of demand growth is going to be a challenge—one that could have major effects on our ability to cut emissions.

This company is trying to make a biodegradable alternative to spandex

IceLoungeMedia IceLoungeMedia

It probably hasn’t been long since you last slipped into something stretchy. From yoga pants to socks, stretch fabrics are everywhere. And they’re only getting more popular: The global spandex market, valued at almost $8 billion in December 2024, is projected to grow between 2% and 8% every year over the next decade. That might be better news for your comfort than for the environment. Most stretch fabrics contain petroleum-based fibers that shed microplastics and take centuries to decompose. And even a small amount of plastic-based stretch fiber in a natural garment can render it nonrecyclable.

Alexis Peña and Lauren Blake, cofounders of Good Fibes, aim to tackle this problem with lab-grown elastics. Operating out of Tufts University and Argonne National Laboratory in Illinois, they are using a class of materials called silk elastin-like proteins (SELPs) to create biodegradable textiles.

“True circularity has to start with raw materials,” says Peña. “We talk about circularity across many industries, but for textiles, we must address what we’re using at the source.”

Engineered from recombinant DNA, SELPs are copycat proteins inspired by silk and elastin that can be customized for qualities like tensile strength, dye affinity, and elasticity. Silk’s amino acid sequences—like glycine-alanine and glycine-serine—give fibers strength, while elastin’s molecular structure adds stretchiness. Combine these molecules like Lego blocks, and voilà!—at least theoretically, you have the ideal flexible fiber.

An early-stage startup, Good Fibes creates its elastics with proteins from E. coli, a common bacterium. The process involves transforming the proteins into a gel-like material, which can then be made into fibers through wet-spinning. These fibers are then processed into nonwoven textiles or threads and yarns to make woven fabrics.

Scaling, however, remains a challenge: To produce a single swatch of test fabric, Blake says, she needs at least one kilogram (approximately two pounds) of microbial material. The fibers must also be stretchy, durable, and resistant to moisture in all the right proportions. “We’re still solving these issues using various chemical additions,” she says. For that reason, she’s also experimenting with plant-based proteins like wheat gluten, which she says is available in larger quantities than bacteria.

Timothy McGee, a biomaterials expert at the research lab Speculative Technologies, says manufacturing is the biggest hurdle for biotextile startups. “Many labs and startups around the world successfully create recombinant proteins with amazing qualities, but they often struggle to turn those proteins into usable fibers,” he says.

One Japanese biomaterials company, Spiber, opened a commercial facility in 2022 to produce textiles from recombinant E. coli proteins using a fermentation process the company first developed in 2007. The following year—after 16 years of prototyping—The North Face, Goldwin, Nanamica, and Woolrich became the first mass-market brands to sell garments using Spiber’s protein-based textiles.

Good Fibes wants to do the same thing, but for stretchy fabrics. The company recently began experimenting with non­woven versions of its textiles after Peña received a $200,000 US Department of Energy grant in 2024. The most popular nonwoven materials are those used in paperlike products, such as surgical masks and paper towels, but Peña envisions a softer, stretchier version that’s almost more like a lightweight felt. She used the grant to buy the company’s first 3D bioprinter, which arrived in January. With it, she’ll begin patterning nonwoven swatches. 

If it’s successful, McGee predicts, a nonwoven stretch fabric could be a more scalable option than wovens. But he adds: “Nonwovens are not very structural, so they’re usually not very tough. The challenge [Good Fibes] will need to show is what level of strength and toughness—at what size and scale—can they produce, and at what cost?”

With additional funding, Peña and Blake plan to develop both woven and nonwoven textiles moving forward. 

Meanwhile, they’ve already forged relationships with at least one major athletic apparel retailer eager to test their future fabric samples. “They’re like, ‘When you get a swatch, send it to us!’” Blake says, adding that she believes Good Fibes will be ready to commercialize in two years.

Until then, their fashion innovation will continue taking shape in the lab. As Blake puts it: “We’re thinking big by thinking small—down to the molecular level.”
