How Tesla's Cybertruck could keep UK homes running for days
Tesla cars could soon function as an effective "battery" to supply British homes with electricity as the electric vehicle (EV) maker's new energy venture also allows homeowners to sell surplus energy back to the grid.
Elon Musk's company is plotting to enter the British energy market and supply households in the coming months.
Tesla has sought approval for an energy licence and reportedly hopes to start supplying energy to homes and businesses in England, Scotland and Wales by next year.
Tesla has been involved in the UK energy market since 2020, when it was granted a licence to be an electricity generator.
How could a Tesla power a home?
In the US, the group has been an electricity supplier for the past three years in Texas, where it supplies electricity via Tesla Electric.
The company's "Powershare" technology means households that own one of Tesla Cybertruck models can essentially use their EV as a power source for the home.
The process is referred to as V2X – vehicle-to-everything.
Because of the sheer size of batteries in EVs, homeowners can effectively "store" electricity in their Tesla. When a power outage is detected, Powershare automatically provides back-up electricity for the home.
The Cybertruck, for example, is capable of delivering 11.5 kilowatts of continuous power and is able to meet the energy needs of an average home for three days.
The vehicle also has multiple 120V and 240V outlets, which can be used to power devices needed for, say, camping trips. Or even to turn the car into a remote workplace.
Paired with other technology – such as home batteries - V2X could allow homes more control over how they buy and use electricity.
Households in Texas have also been able to lower their electricity bills by powering a vehicle at night when electricity is cheap, and then using it to run home appliances during the day.
What other functions might Tesla bring to the UK?
Tesla Electric offers cheap, renewable energy, managed through a mobile app and is built particularly for people who own a Tesla Powerwall home battery or a Tesla vehicle.
With Powerwall, consumers are encouraged to buy electricity at night and sell electricity back to the grid when prices are high – this means that the grid is more stable, and customers with Powerwalls can profit.
Tesla currently offers Powerwall via energy provider Octopus in the UK.
With multiple homes selling electricity to the grid, it works as a virtual power plant, which helps to support the grid at peak times.
Tesla says: 'A virtual power plant (VPP) is a network of distributed energy sources such as homes with solar and battery systems, working together as a single power plant. The combined energy of these sources is used to support the electrical grid.'
Tesla also sells solar panels, which can be used to top up Powerwall batteries.
Declining sales across Europe
The news comes amid a backdrop of waning demand for Tesla's electric vehicles across Europe in recent months.
New car registrations in Britain and Germany more than halved in July from a year earlier. Some have argued Musk's political support for Donald Trump has impacted sales. However, it is also the case that competition has also increased.
Sales of EVs made by China's BYD, for example, rose nearly five-fold in Germany and over four-fold in Britain in July.
Nonetheless, industry figures showed an almost 60% plunge in the number of new Tesla registrations in the UK in July, compared with a year earlier.
In further bad news for Musk, on 1 August a jury in Florida found Tesla liable to pay $243m (£180m) to victims of a 2019 fatal crash of an autopilot-equipped Model S.
Jurors in the Miami federal court awarded the estate of Naibel Benavides Leon, as well as her former boyfriend Dillon Angulo, $129m in compensatory damages plus $200m in punitive damages, according to a verdict sheet.
Tesla has said it will appeal the decision, which could encourage more legal action against the company.

Wall Street's Wild Rally: Why No One Cares About Tariffs Anymore
Investors are in full-on risk modeand they're not waiting around to see how the Trump tariffs play out. From small caps to crypto, riskier corners of the market are lighting up as bets on a Federal Reserve rate cut heat up. The S&P 500 (SPY) is up nearly 30% from its April lows, with Tesla (NASDAQ:TSLA) and other megacap techs carrying most of the load. According to Deutsche Bank, just a handful of tech giants were responsible for 90% of the index's Q2 earnings growth. The Russell 2000 is climbing for the fourth straight month, emerging-market stocks are catching bids, and even speculative European bank bonds are finding buyers. The fear? Gone. Volatility measures like the VIX and MOVE indexes are plumbing their lowest levels in months. Traders are now pricing in a nearly 90% chance the Fed cuts rates in September, with some even betting on a 50-basis-point move. Treasury Secretary Scott Bessent added fuel to that fire, saying rates should probably be 150 to 175 basis points lower. The market has latched onto that narrative. Even currency volatility has dropped to its lowest in a year. All the while, the economic backdrop remains soft: labor market data isn't running hot, inflation came in as expected, and for now, that's enough. The mood is surprisingly bullishit's almost like what tariffs, who cares?' said Neil Birrell, CIO at Premier Miton. That detachment from reality? It's workingat least for now. But not everyone's ready to join the parade. It's very expensive right now to be bearish, said UBS O'Connor's Bernard Ahkong, who still sees plenty of risks lurking in the background. Bloomberg's Mark Cudmore warned that rising long-end yields or another Trump curveball could snap the rally. Still, Wall Street strategistssome of whom had slashed targets back in Aprilare now raising their outlooks. Citigroup's Scott Chronert even bumped up his year-end S&P 500 target, betting that potential tax cuts could outweigh tariff impacts. For now, the market's not trading fearit's trading FOMO.

Fight Over Musk's Role in Shuttering USAID Is Kept Alive by Judge
A lawsuit accusing billionaire Elon Musk of unlawfully directing the closing of the US Agency for International Development can move ahead over the Trump administration's objections, a Maryland federal judge ruled. US District Judge Theodore Chuang on Wednesday rejected the Justice Department's request to toss out a lawsuit that alleges Musk exercised power within the US government that's reserved for Senate-confirmed officials. The judge also left intact a claim that the Department of Government Efficiency project spearheaded by Musk unlawfully took steps to dissolve an agency created by Congress.

The GP1 Looks Like a Greatest Hits Album of Analog Supercars
The latest car news, reviews, and features. A British outfit called Garagisti & Co. is making some waves this week with gorgeous renderings of its super-limited, super-expensive hypercar called the GP1. The design is supposed to be inspired by 'icons of the '80s, '90s, and early 2000s,' and the spirit is all old-school sports driving awesomeness. Non-turbo V12, six-speed manual, rear-wheel drive, and an interior like a midcentury modern psychiatrist's office. Or maybe I'm just projecting that last bit—because it looks like driving this thing would be deeply therapeutic after being bombarded by screens in any other modern vehicle. The car looks complete in these images, and looking at them on a small screen, I thought they were photos at first myself. But the company's press release confirms that they are, in fact, digital renders. Garagisti & Co. states that the car is 'now in advanced stages of engineering and production.' I'm guessing the company's people wanted to roll out the idea to be part of the hypercar hype-wave that is Monterey Car Week, which is currently underway. Unfortunately, few of us will ever see one of these in person anywhere, let alone drive it, as the GP1's creators are only planning to make 25 and charging over $3.3 million (£2.45 million, to be exact) each. Still, it's a very pretty interior and exterior design that simultaneously looks unique while reminding me of a few different cars in the elite class of low-production performance machines. I see a lot of Ford GT, some Lamborghini, Lancia, some Ferrari … any elements look particularly familiar to you? Garagisti & Co. has some big-name supplier collaborators, like Brembo (brakes), Öhlins (suspension), and Xtrac (transmission). But the fact that it's making a 'completely new and bespoke' engine is exceptionally wild. And probably a big part of why the price is so high. I think it's madness to make an entirely custom engine just for 25 cars—how the heck is anybody supposed to find parts for this in five years? Very cool, extremely impractical. I guess that's what cars at this level are kind of all about, though. Garagisti & Co. The V12 will have 6.6 liters of displacement, rev to 9,000 rpm, and claim 800 horsepower (and 'over' 516 lb-ft of torque). Since the car is only supposed to weigh 2,200 pounds (dry), that should be enough juice to enter orbit. It's not clear where the motor's at in development, but conceptually, it sounds awesome. So does the ethos behind the whole project. 'Our vision for Garagisti was born from a simple question,' said Garagisti & Co. co-founder Mario Escudero in a press release. 'What if the golden age of analogue supercars never ended? What if icons like the Countach Evoluzione had sparked a lineage rather than a dead-end? What would the great cars of the '80s, '90s and early 2000s look like today if they'd evolved with new technology but kept their analogue soul? We brought together some of the best minds in the world and answered that question with our hands, our hearts, and our passion. The GP1 is our answer.' Swipe through here to see some more renders of this magnificent beast: The company describes itself as 'a coalition of specialists, not generalists,' listing out key collaborators: I like this trend of super-fancy cars leaning into the ideas of tactility and analoginess. Here's hoping the notion trickles back down to more basic brands and old-world warmth makes a comeback over the kitchen appliance aesthetic so many mid-range cars are leaning into these days.
