Why electricity costs so much in the UK (it’s not all about the weather)
The UK government is reportedly considering abandoning its goal of removing fossil fuels from the country’s electricity supply by 2030 in an attempt to keep energy bills down.
This is understandable given that the UK is already one of the most expensive places in Europe to use electricity, something that—despite plenty of investment in relatively cheap renewable energy—is unlikely to change any time soon. In fact, bills remain high even when wind farms are spinning at full capacity.
However, neither a drive to decarbonize the grid—which is needed for other reasons—nor abandoning this target is going to make energy significantly cheaper. The reason for this lies in how electricity markets work, and in the geography and policies that shape the UK’s energy system.
To begin with, wholesale electricity prices are determined in a way that essentially means that everyone has to pay for the most expensive source of electricity used at a given time, which in the UK is mostly gas power plants.
The gas which is burned to power the UK’s lights and kettles has to be liquefied, shipped from the US or Qatar amid global bidding wars, and then converted back into its original state. High gas prices drive high wholesale prices, which directly translate into high electricity bills.
Cheaper renewable energy sources (the cost of producing solar, wind or nuclear electricity is very low) have little effect. This is partly because while the operating cost of renewable electricity is very low, the cost of setting it up is not.
To encourage companies to build new generation capacity, the government must offer them a guaranteed price for the electricity they produce, to compensate for their costs. For a wind farm, this would include money for planning applications, as well as buying and installing turbines and electrical equipment.
Bringing different sources of electricity to consumers also requires expensive infrastructure investment. In the UK, for example, grid capacity is not where it needs to be after decades of low investment.
Nearly 40% of the electricity produced by Scottish wind farms has been wasted so far this year, because the grid was not able to move it to other parts of the UK or store it.
Overall then, consumers’ bills will be high, both now and in the future, because of the combined costs of imported gas, infrastructure and the guaranteed prices for producers.
Most calls to decrease these bills effectively come down to suggesting moving some of these costs on to taxpayers—so effectively from one bill to another. This is what happened in France, where “cheap” nuclear electricity is the result of vast amounts of government spending in the past. The French may not see UK-level energy bills, but they do have higher taxes and public debt.
Clouds on the horizon
Despite these challenges, successive UK governments have committed to continuing investment in new technologies, because dependence on imported, polluting and volatile fossil fuels is deemed too risky. Postponing the full transition to renewables, as reported in the Guardian, is effectively a bet that gas prices will decrease in the short term, and that the UK will be able to commission cheaper renewables later on.
But cheaper renewables present their own problems, because they play different roles. Solar and wind are cheaper, but intermittent. Nuclear is the most expensive but works all the time.
This all presents a challenging situation for UK consumers. New nuclear faces very long safety and planning procedures and the national grid needs to be modernized. The decision to cancel an ambitious project to get solar electricity from Morocco may be regretted.
But the main factor is simply geography and timing. Partly due to its location, the UK has become a world leader in wind power, a renewable technology that seems to be taking a less important global role than solar. And while the cost of solar production is decreasing steeply, the learning curve is slower for wind.
And there is no obvious way to increase the number of sunny hours in England. A country like Spain, with both a lot of sun and wind, has a much easier job transitioning to cheap renewables than the UK.
So, for all the frustration over high bills, the UK’s options are limited. Geography gives us wind, not sunshine. Policy has delivered world-class renewables, but also a grid struggling to carry their power.
The future will depend on whether new technologies, including cheaper batteries, tidal power and small modular nuclear reactors can fill the gaps left by weather and planning delays.
None of this will be easy or cheap. But the alternative—continued dependence on imported, volatile fossil fuels that make bills hostage to global crises—is worse.
UK consumers face a future where electricity remains more expensive than much of Europe, not only because of policy choices, but because it lacks the sunshine that’s driving costs down elsewhere. Betting on emerging technologies is the only way to close that gap.

I Tested Garmin Watches for a Decade While Hiking, Biking, and Climbing. Here’s What You Should Buy
Last year, Garmin introduced a Pro version that incorporates the inReach’s satellite communications savvy. Not only does it cost at least $400 more than the Apple Watch Ultra and $200 more than the regular Fenix 8, but you also have to pay for the inReach subscription plan, which has several tiers and ranges from $8/month to $50/month depending on whether you want features like unlimited texting or sending photo messages.
What you get for this mind-boggling price is a sports watch that can do anything and everything. It has best-in-class battery life (every Fenix can last for weeks on a single charge, and up to a month with solar charging) and features like the depth sensor from Garmin’s Descent line, which means this watch works as a full-on dive computer for scuba and free diving. It has a microphone and speaker for basic voice commands (although no onboard cellular connectivity), the surprisingly useful built-in LED flashlight, and Garmin’s signature built-in topographic maps, 24/7 health monitoring, and tracking for over a hundred different activities.
I’ve taken the 51-mm version on pretty much every outdoor sport—snowboarding, trail running, mountain biking, and rock climbing. Every time I use it, its capabilities far outclass my own. I have irritated many a fellow climber by attempting to track route difficulty, duration, and falls while integrating my Body Battery metrics and so on. The danger is always that you’ll spend more time fiddling with your Garmin Fenix 8 than you do with your actual sport. I have the version with the sapphire glass face and the titanium bezel, and have smashed it into rock faces with nary a scratch. If you’re up for paying the price and want a good-looking watch that will last forever (I have friends who are still wearing their Fenix 5s and 6s, and honestly, they’re fine), this is the one to get.
Best Running Watch
The Garmin Forerunner series launched in the early 2000s and has become the quintessential runner’s watch. Like all Garmins, the Forerunner comes in a range of price points, each offering different features. Last year, Garmin released the Forerunner 570 ($550), a midrange model with no LED flashlight or onboard maps, and the Forerunner 970 ($750), which is the premium version. Before I go into detail about why the Forerunner 970 is the best option, I should also say that I have tested many previous Garmin Forerunners at various price points. If you’re not a triathlete, the older Forerunners are still worth considering, and the entry-level $200 Forerunner 165 is aimed explicitly at runners, instead of including triathletes as the more expensive models do.

Save Up to 40% With These Acer Promo Codes and Discounts
Acer is one of the top largest PC manufacturers in the world, perhaps best known for its gaming line and budget-friendly options. If you’ve already got your eye on an Acer product like a laptop or monitor, and are shopping at the company’s online storefront, you should be using one of these Acer promo codes and coupons to save some cash on your purchase.
Save 40% on Accessories When You Build an Acer Bundle
If you’re buying from Acer, you’re most likely shopping for either a desktop PC or laptop. With this discount, you can get a really solid deal on accessories if you bundle it with a mouse, laptop bag, or headset. When you go to purchase a PC, just click “Build Bundle” and you’ll see some of the eligible options, all of which are reduced by 40%. The Nitro Mechanical Keyboard, for example, goes from $50 to just $30. That 40% is a real discount, too, as that same keyboard costs $50 on Amazon when I checked.
Beyond peripheral add-ons, you can also save 10% off Acer Care Plus extended service plans or McAfee LiveSafe antivirus subscriptions. You can bundle up to five products together to save the most money. If you’re headed off to college (or have a kid in the family), a bundle like this can get you everything you need for a gaming or studying setup on the go.
Shop Rotating Weekly Deals on Monitors and Gaming Gear
Acer’s PC gaming offerings come in either the flagship Predator brand or the budget-tier Nitro. Acer offers rotating weekly deals on everything from monitors to gaming laptops, some of which are my favorites that I’ve tested in their given category. The Acer Nitro V 16, for example, was a budget gaming laptop that I recommended quite a lot last year because of its incredible price. The one I tested was the entry-level version with an Nvidia RTX 5050 inside, but Acer has the RTX 5060 model in its own storefront. It’s $100 off right now at $1,200, which comes with 16 GB of RAM and a terabyte of storage. In fact, it’s only $30 more than the RTX 5050 model, despite offering a significant jump in gaming performance. These discounts are reflected right on the product pages, so there’s no promo code, discount code, or coupon code required.
Acer has a wide selection of monitors available, too, whether that’s a massive 49-incher or a more modest 27-inch gaming workhorse. One of my favorite discounts I saw right now was the Acer Nitro XV2, a 27-inch 1440p display with a 300 Hz refresh rate. It’s 44% off at the time of writing, bringing the price down to just $250. Because these discounts are swapped out on a weekly basis, it’s worth checking back to see if the product you’re eyeing has a new discount.
Select Customers Can Get 15% Off Their Purchase
Acer also offers a number of added discounts at checkout, including 15% off for students. Students will need to verify through Student Beans or SheerID. Because a lot of the devices Acer offers are budget-friendly, they can be attractive for students, and the extra 15% off is the icing on the cake.
We tested the Acer Swift 16 AI last year and really enjoyed the high-resolution, OLED screen and impressively quiet performance. Acer has the smaller version of this same laptop available, the Swift 14 AI, which is currently $150 off. You also might check out the Acer Chromebook Plus 514, a laptop we liked quite a bit when we reviewed it in 2024.
Acer offers this same 15% discount for active duty military, veterans, and their families. It also applies to healthcare professionals, which can be verified through its healthcare discount portal.

AI Research Is Getting Harder to Separate From Geopolitics
The world’s top AI research conference, the Conference on Neural Information Processing Systems—better known as NeurIPS—became the latest organization this week to become embroiled in a growing clash between geopolitics and global scientific collaboration. The conference’s organizers announced and then quickly reversed controversial new restrictions for international participants after Chinese AI researchers threatened to boycott the event.
“This is a potential watershed moment,” says Paul Triolo, a partner at the advisory firm DGA-Albright Stonebridge who studies US-China relations. Triolo argues that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some American officials have pushed for American and Chinese scientists to decouple their work—especially in AI, which has become a particularly sensitive topic in Washington.
The incident could deepen political tensions around AI research, as well as dissuade Chinese scientists from working at US universities and tech companies in the future. “At some level now it is going to be hard to keep basic AI research out of the [political] picture,” Triolo says.
In its annual handbook for paper submissions, issued in mid-March, NeurIPS organizers announced updated restrictions for participation. The rules stated that the event could not provide services including “peer review, editing, and publishing” to any organizations subject to US sanctions, and linked to a database of sanctioned entities. It included companies and organizations on the Bureau of Industry and Security’s entity list and those on another list with alleged ties to the Chinese military.
The new rules would have affected researchers at Chinese companies like Tencent and Huawei who regularly present work at NeurIPS. The database also includes entities from other countries such as Russia and Iran. The US places limits on doing business with these organizations, but there are no rules around academic publishing or conference participation.
The NeurIPS handbook has since been updated to specify that the restrictions apply only to Specially Designated Nationals and Blocked Persons, a list used primarily for terrorist groups and criminal organizations.
“In preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow,” the event’s organizers said in a statement issued Friday. “This error was due to miscommunication between the NeurIPS Foundation and our legal team.”
Before they reversed course, the conference organizers initially said that the new rule was “about legal requirements that apply to the NeurIPS Foundation, which is responsible for complying with sanctions,” adding that it was seeking legal consultation on the issue.
Immediate Backlash
The new rule drew swift backlash from AI researchers around the world, particularly in China, which produces a large quantity of cutting-edge machine learning papers and is home to a growing share of the world’s top AI talent. Several academic groups there issued statements condemning the measure and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Some urged Chinese academics to contribute instead to domestic research conferences, potentially helping increase the country’s influence in relevant science and tech fields.
The China Association of Science and Technology (CAST), an influential government-affiliated organization for scientists and engineers, said Thursday that it would stop providing funding for Chinese scholars traveling to attend NeurIPS and would use the money instead to support domestic and international conferences that “respect the rights of Chinese scholars.”
CAST also said it will no longer count publications at the 2026 NeurIPS conference as academic achievements when evaluating future research funding. It’s unclear if the organization will reverse course now that NeurIPS has walked back the new rule.
