How electric cars and heat pumps can help Switzerland implement its energy strategy

In the future, flexibly operated heat pumps and electric cars could reduce both electricity imports and electricity prices. That is according to a new study by a Swiss research consortium led by ETH Zurich.

Electric cars and could play a major role when it comes to implementing the Swiss Energy Strategy. The Federal Council is aiming for Switzerland’s energy supply to be carbon-neutral by 2050. The plan is for heat pumps to replace oil and gas-fired heating systems and for to gradually replace combustion vehicles. This will result in a significant increase in demand for electricity—from around 56 terawatt-hours (TWh) a year today to around 75 TWh a year by 2050.

A new report by the Swiss “PATHFNDR” research consortium, which is part of the “SWEET” program, has now shown that, alongside hydropower, heat pumps and electric cars could be key providers of flexibility for the Swiss power system in 2050.

Christian Schaffner, Director of the Energy Science Center at ETH Zurich and Deputy Director of the project, explains, “The two technologies serve to better coordinate rising with from renewable energy sources. This relieves the burden on the , reduces imports and brings down wholesale electricity prices—particularly in the winter months.”

Only consume if the grid is not at full capacity

This flexibility is apparent on an everyday basis. For example, at outdoor temperatures of 0°C, intelligently controlled heat pumps can switch off for up to 10 hours in buildings meeting the Minergie standard without a noticeable drop in room temperature. This helps to avoid having too many heat pumps running at the same time and overloading the grid.

Electric cars, too, are often connected to the grid for much longer than is necessary for a full charge—for example if they are plugged in to charge in the garage at the end of the working day. This allows for an optimum charging pattern that is in line with electricity supply. The study claims that the best thing would be to charge the car at work: “During the day, when the sun is shining, many vehicles are parked anyway. Charging them there would make optimum use of photovoltaic production,” explains Siobhan Powell, an energy researcher at ETH Zurich and one of the main authors of the study.

More electricity, less electricity imports

By 2050, Switzerland wants to cover 50 to 60% of its electricity demand (45 TWh per year) with new such as photovoltaics, wind energy or biomass. The researchers’ model calculations now show that this target will be easier to reach thanks to the flexible power consumption of heat pumps and electric vehicles.

If heat pumps and electric cars are coordinated and controlled flexibly on a nationwide basis, around 4% more renewable electricity could be available in Switzerland in 2050. “Most of this is solar power in spring and summer, which would be utilized more efficiently so that it does not need to be curtailed,” explains Powell.

Moreover, flexible heat pumps and electric cars could reduce net electricity imports by around 20% across the whole year, particularly due to higher net exports in spring and summer. “These amount to some 1.8 TWh of electricity, which is equivalent to the annual consumption of around 0.5 million Swiss households,” says Powell. According to the study, Switzerland’s electricity imports would also be reduced by around 0.7 TWh in the winter months. That corresponds to a 4.4% reduction in net imports in winter compared to an energy system without flexibly operated heat pumps and electric cars.

Cheaper electricity and fewer gas power stations

In addition, the study shows that wholesale electricity prices could also be lower due to a more even distribution of supply and demand with the help of flexible heat pumps and electric cars. This reduction in is greatest in the winter months of January to March, when wholesale prices could be reduced by up to 6%.

The researchers also estimate that an electricity system supported by flexible heat pumps and electric cars could be operated with around 4% lower costs than a system without these two flexibility providers.

Moreover, the use of flexibly operated heat pumps and electric cars would also mean the construction of fewer gas power stations and battery storage systems by 2050. Estimates show that the necessary investment in gas power stations and batteries would fall by around a third. “Above all, gas power stations and batteries are necessary to compensate for peaks in electricity demand. If electric vehicles and heat pumps take over this function, we’ll need fewer of them,” explains Powell.

Flexibility yes, but also convenience

According to a representative survey carried out as part of the study, about 70% of the Swiss population is willing to contribute to grid stability through flexible heating and charging, provided their convenience is not impacted and operation is automatic. About 30% of respondents even said they would accept minor inconveniences if this would bring down their electricity costs.

Lower peak loads in neighborhoods and reduced grid expansion

If a large number of households are charging their cars or running their heat pumps at the same time, there is a risk of bottlenecks in the distribution grid. Many of today’s power cables and transformers are not designed for these loads and would need to be reinforced.

The researchers analyzed about 50 grid areas in Switzerland and concluded that flexibly operated heat pumps and electric cars would reduce peak loads in neighborhoods and could therefore delay and reduce the need for expensive reinforcement work on distribution grids. The actual size of these effects also depends on whether the areas in question are urban or rural.

Electricity tariffs that reward citizens

So that electrical vehicles and heat pumps can actually act as flexibility providers by 2050, they must be equipped with the necessary control and communication technology. At present, this is not the case across the board. The authors of the study therefore recommend that further systems only be subsidized if they allow flexible and intelligent operation.

In addition, the operators of electric vehicles and heat pumps should be incentivized to change their heating and charging behavior. To this end, the study recommends measures including dynamic electricity tariffs that reward flexible charging and heating. However, significant local differences in tariffs and feed-in payments would hinder this measure’s implementation in Switzerland, states the study.

The researchers also point out that the promotional instruments in Switzerland are very heterogeneous and that there is, as yet, no national “right to charge” for tenants with electric vehicles—something they say ought to be resolved quickly.

Hyperkin’s Competitor Upgrades the Xbox Controller by Copying Sony’s Design

Hyperkin’s Competitor Upgrades the Xbox Controller by Copying Sony’s Design


The most immediately striking difference is that Hyperkin’s product swaps the typical Xbox approach of asymmetric thumbsticks for the PlayStation’s horizontal layout. It also separates the D-pad (it’s one piece inside the pad, but splits its cardinal directions so each appears to be its own button), while the ABXY face buttons are spaced slightly further apart. Where the DualSense’s touchpad would sit, we have the Xbox home, menu, view, and share buttons, all blended in rather smartly. An LED ring around the home button just about echoes the lights running the periphery of the DualSense’s touchpad, although it’s really more of an inversion of the regular Xbox controller, where the home button itself lights up.

The Competitor’s thumbsticks come equipped with thumbcaps that mirror the PS5’s, an outer ring with a convex central point, but a pair of Xbox-standard concave caps are included. These easily pop on and off, and can be mixed and matched, if you were so (strangely) inclined.

There are two areas where this departs from both the standard Xbox and PlayStation controllers in terms of inputs. The first is the presence of two programmable rear buttons, M1 and M2. By default, these duplicate the input of the A and B buttons, but holding down the Mode button between them lets you remap them. There are also physical button locks to prevent their use entirely. The other is that while the Competitor boasts a 3.5-mm headphone jack like Microsoft’s official pad, it adds a built-in audio mute button, hidden in the black between the thumbsticks—a nice little upgrade.

Oddly Familiar

In use, the Competitor feels … well, a lot like a PS5 pad. The slightly wider grip fits in the hand comfortably, all inputs are accessible, and those symmetrical thumbsticks sit nicely in reach for all but the smallest hands. A microtextured underside provides a solid grip that, when coupled with its 232-gram weight, makes the Competitor feel particularly suited to longer play periods. It’s all very familiar if you’re already a multiformat gamer, to the extent that it sometimes slightly threw my muscle memory off, reaching a thumb out to do a PlayStation touchpad function and finding only the Xbox system buttons.

In Cryptoland, Memecoin Fever Gives Way to a Stablecoin Boom

In Cryptoland, Memecoin Fever Gives Way to a Stablecoin Boom


When US president Donald Trump launched his own meme cryptocurrency on January 17, days before his return to the White House, I was halfway up a Swiss alp, attending a crypto conference in the town of St. Moritz.

Memecoins, which typically have no purpose beyond financial speculation, were having a moment. The previous year, millions of new memecoins had flooded the market; a few, like Fartcoin, had rocketed to billion-dollar valuations. Pump.Fun, a platform for launching and trading memecoins, had become one of the fastest-growing crypto launchpad businesses ever. Now, the soon-to-be president was getting in on the act.

Over lunch on the second day of the conference, beneath the ornate stucco ceiling and golden chandeliers of the venue’s dining hall, I located a table designated for a conversation about memecoins. Whereas other tables were half full, the memecoin workshop was oversubscribed; latecomers pulled up chairs to create two full rows.

The discussion was led by Nagendra Bharatula, founder of investment firm G-20 Group. Bharatula had recently coauthored a paper arguing that memecoins, despite their juvenile spirit, had a place in professional investors’ portfolios. In the six months prior, a basket of 25 “bluechip memecoins”—an oxymoron if ever there was one—had outperformed bitcoin by 150 percent, he pointed out. Some of the attendees murmured their approval.

Since then, the shine has come off the memecoin market. The paper value of Trump’s coin, which climbed to a peak of $14 billion two days after its launch, has cratered to roughly $1 billion. Hundreds of thousands of small investors lost their shirts. Pump.Fun’s daily revenue, a proxy for the overall appetite for memecoin trading, is barely more than a tenth of what it was in January. The memecoin gold rush has spawned a raft of litigation.

Next up: the stablecoin. If memecoins are symbolic of reckless abandon and unflinching profiteering in cryptoland, stablecoins are a symbol of the industry’s search for purpose and respectability. Designed to hold a steady $1 valuation, stablecoins are pitched by proponents as a faster and cheaper way to make everyday payments and international money transfers.

In a year in which the US has declared itself open for crypto business, where previously crypto firms feared regulatory backlash under the Biden administration, stablecoins have supplanted memecoins as the coin à la mode—and punctured the mainstream.

Though stablecoins have been around since 2014, they have predominantly been used by crypto traders as a safe harbor during bouts of market volatility, not by regular people. The concept has also faced resistance from regulators skeptical of a new form of money; Diem, a stablecoin venture incubated at Meta, famously shuttered in 2022 in the face of broad-based opposition.

Best HelloFresh Coupons and Promo Codes for December 2025


Leveraging meal kit coupons is the extreme couponing of our times—a capitalism hack-a-thon right up there with trial yoga classes and attempting to cancel your Adobe subscription. Meal kits like HelloFresh have always been a better deal than they get credit for, even at full price: It’s actually hard to recreate meal kit meals for less than you can get the recipes delivered to your home. But it’s especially worth it when you can find a HelloFresh coupon, promo code, or discount at more than half off.

I’ll admit I wasn’t that sold on HelloFresh when I first tried it most of a decade ago. It was useful, it got me out of my staid routines, but I wasn’t impressed with the selection. It felt a little basic. But lately? Honestly, it’s kinda cosmopolitan these days, after expanding to a dozen countries and absorbing the supply networks from multiple other meal plans. When I last tested the HelloFresh meal kit (7/10, WIRED Recommends), I was surprised to find myself cooking credible home renditions of ramen, ponzu-plum beef stir fry, and Southwest-accented pork roasts. And when I’m able to pick up a HelloFresh discount code, it’s generally less than I’d spend on groceries anyway. So it’s a good moment to try out a lifestyle where the food comes in the mail.

Get 50% Off and up to 10 Free Meals as a New HelloFresh Customer

Right now, new and returning customers can take advantage of a HelloFresh discount code offering 50% off your first meal kit box plus a free item each week. Enter your email as part of the signup process, and you’ll be auto-subscribed to an email with even more offers for both new and existing customers. Plus, new customers can get up to 55% off and extra free breakfasts, desserts, and other items with other secret discounts.

HelloFresh Student and Discount: 55% Off, Free Shipping, Plus Extra 15% Off Education Discounts Available via UNiDAYS

HelloFresh meal kits are pretty amenable to dorm life when ordering the ready-to-eat meals—or just saving time during grad school instead of ordering pizza, by letting the Internet do your shopping and meal planning. But student budgets tend to be tight, of course. And so there are steeply discounted HelloFresh coupon codes specifically for students. Follow the link here for a HelloFresh education promo code offering 55% off your first box, free shipping, and a continuing discount of 15% off for the first year.

Discounts also apply to teachers who’ve never tried HelloFresh. Educators and school employees can get up to 12 free meals spread out across 3 boxes, plus free shipping. Click here for the HelloFresh promo code, or go here for more information about educator discounts.

Give $40, Get $10 With the HelloFresh Referral Program

Already a HelloFresh subscriber? You’re still eligible for discounts if you pass along subscription information to your friends. Here’s how: Send your friends a $40 discount for their own affordable meal kits. Once they sign up using your HelloFresh referral code, you’ll also get a $10 credit on your next delivery.

These discounts stack. So if you sign up multiple friends with your referral code, you get multiple $10 discounts. Check out the HelloFresh meal kit referral program here.

Take Advantage of HelloFresh Come Back Offers

Some of these discounts are only available to new HelloFresh customers. But there’s a hack to getting discounts anyway. After you pause or cancel your subscription, check your inbox after the next few days or weeks. Often, you’ll get HelloFresh coupon codes for discounts.

Typical HelloFresh “come-back” offers after a canceled subscription include: $100 to $180 off (spread out over several meal boxes), free shipping on the first box (after re-subscribing), free items such as dessert, breakfast, or an extra protein per meal, or a free meal box is offered after a break. Typical retention offers, for when customers try to cancel, include: 40% off the next box, if you decide not to cancel, or 25% off the next two meal kits. None of this is failsafe, of course, offers vary for each customer. But as with magazine subscriptions, sometimes canceling, or trying to cancel, will lead to a good discount offer from a company eager to keep your business.

When to Save the Most on HelloFresh Subscriptions

HelloFresh almost always has some sort of deal going, whether to bring in new customers with an especially choice HelloFresh coupon, or bring back previous customers with HelloFresh discount codes and retention offers. But summer tends to be one of the times they offer the steepest discounts, including 10 free meals across several boxes, complimentary appetizers, free ready-made items, or free shipping on select boxes.

The other big times for HelloFresh coupon codes are around Black Friday and the end of the year. HelloFresh often launches limited-edition holiday meal boxes and themed meal kits, not to mention discounts for returning customers looking to cook more at home as part of New Year’s resolutions.
