Solar energy is now the world’s cheapest source of power, study finds
Solar energy is now so cost-effective that, in the sunniest countries, it costs as little as £0.02 to produce one unit of power, making it cheaper than electricity generated from coal, gas or wind, according to a new study from the University of Surrey.
In a study accepted for publication in Energy and Environment Materials, researchers from Surrey’s Advanced Technology Institute (ATI) argue that solar photovoltaic (PV) technology is now the key driver of the world’s transition to clean, renewable power.
Professor Ravi Silva, co-author of the study and Director of the ATI at the University of Surrey, said, “Even here in the U.K., a country that sits 50 degrees north of the equator, solar is the cheapest option for large-scale energy generation.
“Globally, the total amount of solar power installed passed 1.5 terawatts in 2024—twice as much as in 2020 and enough to power hundreds of millions of homes. Simply put, this technology is no longer a moonshot prospect but a foundational part of the resilient, low-carbon energy future that we all want to bring to reality.”
The research team also found that the price of lithium-ion batteries has fallen by 89% since 2010, making solar-plus-storage systems as cost-effective as gas power plants. These hybrid setups, which combine solar panels with batteries, are now standard in many regions and allow solar energy to be stored and released when needed, turning it into a more reliable, dispatchable source of power that helps balance grid demand.
Despite many reasons to be optimistic, the ATI research team points to several challenges—particularly connecting large amounts of solar power to existing electricity networks. In some regions, such as California and China, high solar generation has led to grid congestion and wasted energy when supply exceeds demand.
Dr. Ehsan Rezaee, co-author of the study from the University of Surrey, commented, “Connecting growing levels of solar power to electricity networks is now one of the biggest challenges. Smart grids, artificial intelligence forecasting and stronger links between regions will be vital to keep power systems stable as renewable energy use rises.”
Professor Silva added, “With the integration of energy storage and smart grid technologies, solar is now capable of delivering reliable, affordable and clean power at scale. Innovations in materials such as perovskite solar cells could boost energy output by up to 50% without increasing land use.
“However, progress will depend on consistent, long-term policy support. Initiatives such as the Inflation Reduction Act in the US, the EU’s REPowerEU plan and India’s Production Linked Incentive scheme show how clear direction can drive investment and innovation. Sustained commitment and international collaboration will be essential if we are to accelerate the world’s transition to a clean and reliable energy system.”

This Backyard Smoker Delivers Results Even a Pitmaster Would Approve Of
While my love of smoked meats is well-documented, my own journey into actually tending the fire started just last spring when I jumped at the opportunity to review the Traeger Woodridge Pro. When Recteq came calling with a similar offer to check out the Flagship 1600, I figured it would be a good way to stay warm all winter.
While the two smokers have a lot in common, the Recteq definitely feels like an upgrade from the Traeger I’ve been using. Not only does it have nearly twice the cooking space, but the huge pellet hopper, rounded barrel, and proper smokestack help me feel like a real pitmaster.
The trade-off is losing some of the usability features that make the Woodridge Pro a great first smoker. The setup isn’t as quite as simple, and the larger footprint and less ergonomic conditions require a little more experience or patience. With both options, excellent smoked meat is just a few button presses away, but speaking as someone with both in their backyard, I’ve been firing up the Recteq more often.

Setting up the Recteq wasn’t as time-consuming as the Woodridge, but it was more difficult to manage on my own. Some of the steps, like attaching the bull horns to the lid, or flipping the barrel onto its stand, would really benefit from a patient friend or loved one. Like most smokers, you’ll need to run a burn-in cycle at 400 degrees Fahrenheit to make sure there’s nothing left over from manufacturing or shipping. Given the amount of setup time and need to cool down the smoker after, I would recommend setting this up Friday afternoon if you want to smoke on a Saturday.

Make the Most of Chrome’s Toolbar by Customizing It to Your Liking
The main job of Google Chrome is to give you a window to the web. With so much engaging content out there on the internet, you may not have given much thought to the browser framework that serves as the container for the sites you visit.
You’d be forgiven for still using the default toolbar configuration that was in place when you first installed Chrome. But if you take a few minutes to customize it, it can make a significant difference to your browsing. You can get quicker access to the key features you need, and you may even discover features you didn’t know about.
If you’re reading this in Chrome on the desktop, you can experiment with a few customizations right now—all it takes is a few clicks. Here’s how the toolbar in Chrome is put together, and all the different changes you can make.
The Default Layout
Take a look up at the top right corner of your Chrome browser tab and you’ll see two key buttons: One reveals your browser extensions (the jigsaw piece), and the other opens up your bookmarks (the double-star icon). There should also be a button showing a downward arrow, which gives you access to recently downloaded files.
Right away, you can start customizing. If you click the jigsaw piece icon to show your browser extensions, you can also click the pin button next to any one of these extensions to make it permanently visible on the toolbar. While you don’t want your toolbar to become too cluttered, it means you can put your most-used add-ons within easy reach.
For the extension icons you choose to have on the toolbar, you can choose the way they’re arranged, too: Click and drag on any of the icons to change its position (though the extensions panel itself has to stay in the same place). To remove an extension icon (without uninstalling the extension), right-click on it and choose Unpin.
Making Changes
Click the three dots up in the top right corner of any browser window and then Settings > Appearance > Customize your toolbar to get to the main toolbar customization panel, which has recently been revamped. Straight away you’ll see toggle switches that let you show or hide certain buttons on the toolbar.

The Piracy Problem Streaming Platforms Can’t Solve
“The trade-off isn’t only ethical or economic,” Andreaux adds. “It’s also about reliability, privacy and personal security.”
Abed Kataya, digital content manager at SMEX, a Beirut-based digital rights organization focused on internet policy in the Middle East and North Africa, says piracy in the region is shaped less by culture than by structural barriers.
“I see that piracy in MENA is not a cultural choice; rather, it has multiple layers,” Kataya tells WIRED Middle East.
“First, when the internet spread across the region, as in many other regions, people thought everything on it was free,” Kataya says. “This perception was based on the nature of Web 1.0 and 2.0, and how the internet was presented to people.”
Today, he says, structural barriers still lead many users towards illegal platforms. “Users began to watch online on unofficial streaming platforms for many reasons: lack of local platforms, inability to pay, bypassing censorship and, of course, to watch for free or at lower prices.”
Payment access also remains a major factor. “Not to mention that many are unbanked, do not have bank accounts, lack access to online payments, or do not trust paying with their cards and have a general distrust of online payments,” Kataya adds.
Algerian students also share external hard drives loaded with television series, while in Lebanon streaming passwords are frequently shared across households. In Egypt, large Telegram channels distribute content across different genres, including Korean dramas, classic Arab films and underground music.
“We grew up solving problems online,” says Mira. “When something is blocked, you find a way around it. It’s … a fundamental human instinct.”
Streaming Platforms Adapting
Andreaux says StarzPlay has tried to address some of the payment barriers that limit streaming adoption in the region. “StarzPlay recognized early that payment friction was a regional barrier to adoption,” he says. “That’s why we invested in flexible subscription models and alternative payment methods, including telecom-led billing options that make access easier across different markets.”
At the same time, international media companies are working together to combat piracy through the Alliance for Creativity and Entertainment (ACE), a coalition of film studios, television networks and streaming platforms that targets illegal distribution of films, television and sports content. Its members include global companies such as Netflix as well as regional players like OSN Group, which operates the streaming service OSN+ across the Middle East and North Africa.
Kataya notes that legitimate streaming platforms are still expanding across the region. “The user base of official streaming platforms has been growing in the region,” he says. “For example, Shahid, the Saudi platform, is expanding and Netflix has dedicated packages for the region.”
“Other players, like StarzPlay and local platforms in Egypt, are also finding their place,” Kataya adds. “Social media also plays a huge role, especially when a film is widely discussed or controversial.”
Piracy carries legal and security risks, Andreaux says. “Rather than just ‘free streaming’, piracy exposes consumers to malware and insecure payment channels,” he says. “It also weakens investment in local content by depriving creators of revenue and reducing jobs.”
But the structural barriers described by users across the region remain. For many viewers in North Africa and the Levant, the challenge is not choosing between piracy and legality—it is whether legitimate access exists at all.
