Energy firms’ customer service plummets to record lows, Citizens Advice says

With call waiting times rising and customers saying they can’t get hold of their supplier, the average score (2.8 stars) for the Citizens Advice’s ratings table is the lowest on record. Standards have plummeted since June 2021 when the energy market started to collapse, with millions of customers shifted to new suppliers as a result of their own provider failing. To prevent such a scenario occurring again, UK energy regulator Ofgem recently announced tough new measures to prevent waves of suppliers from failing during future periods of price volatility. Citizens Advice is warning the decline is happening at a time when people need good customer service the most. Between January and March 2022, the charity’s Consumer Service helpline saw more than 70,000 cases related to energy issues…

US Supreme Court restricts government's powers to regulate carbon emissions

The administration of US President Joe Biden has suffered a significant blow, as the country's highest court has ruled that the country's Environmental Protection Agency (EPA) did not have the authority to limit emissions that contribute to climate change across whole states. The court sided with 19 conservative states and fossil fuel companies in a case against the EPA brought by West Virginia. In its 6-3 ruling, the court said that only Congress, not the EPA, has the power to create a broad system of cap-and-trade regulations to limit emissions from existing power plants. Biden called the ruling a "devastating decision" but said that it will not undermine his administration's efforts to curb climate change and reach the goal to completely cut all carbon emissions from power plants by…

Qatar World Cup will use semi-automated offside technology, Fifa announces

The system will provide an automated offside alert to the on-field officials to help them make faster, more accurate and more consistent offside decisions. Video assistant referee (VAR) technology was first introduced at the 2018 Fifa World Cup in Russia and Fifa has spent the last few years improving the system. The new technology uses 12 dedicated tracking cameras mounted underneath the roof of the stadium to track the ball and up to 29 data points of each individual player, 50 times per second, calculating their exact position on the pitch. The 29 collected data points include all limbs and extremities that are relevant for making offside calls. The official match ball for the tournament, ' Al Rihila ', will also provide further data as it includes an inertial measurement unit (IMU…

Jet fuel produced by common soil bacteria

“In chemistry, everything that requires energy to make will release energy when it’s broken,” said lead author Pablo Cruz-Morales from the Technical University of Denmark. When petroleum jet fuel is ignited, it releases a tremendous amount of energy in order to give planes enough lift to escape gravity. The researchers recreated a molecule called Jawsamycin - named after the movie Jaws because of its bite-like indentations - by using the common bacteria streptomyces. “The recipe already exists in nature,” Cruz-Morales said. The jagged molecule is produced by native metabolism of the bacteria as they munch away on glucose.

Government fails to rule out EV tax as new regulations come into force

However, the government failed to rule out introducing a new tax as a way of replacing almost £30bn of revenue it stands to lose in fossil fuel taxes as petrol and diesel cars are replaced by electric models. Under The Electric Vehicles (Smart Charge Points) Regulations 2021, that come into force today, all newly fitted EV charge points must have smart functionality. This will allow for the potential of 'electricity rationing' by deciding when EVs can be charged, helping to avoid overloading the National Grid at peak times. It will also enable EV charger usage to be billed at higher electricity prices than domestic electricity by operating with a dedicated smart meter. Currently, petrol and diesel drivers pay fuel duty at 52.95 pence per litre, which brought in £28bn for the government…

Switch to energy-efficient LED lighting now to mitigate energy crisis, company says

Signify argues that the switch to LED lighting would help the millions of families pushed into fuel poverty due to the recent surge in energy prices by saving each household up to £250 per year. The move would also benefit businesses and could deliver a quick win for the UK’s net-zero ambitions. With the recent change in price cap introduced in April 2022, millions of households have been pushed into fuel poverty and several businesses are now facing added volatility due to its impact. Earlier this week, for example, it was reported that the automotive industry is facing a 50 per cent hike in energy costs this year. In response to the energy price squeeze, Signify – a long-established name in lighting – is advocating an accelerated transition to energy-efficient connected LED lighting.…

Digital-twin makeover

On the face of it, the decision by Siemens and Nvidia to forge a link between their tools seems simple enough. So simple that executives from both companies were at pains to point out that it really isn’t that simple. The core of the agreement, presented at a joint event on Wednesday, will be to ensure Siemens tools that are used to design everything from chips to factories will ultimately be able to feed data to Nvidia’s virtual-world building software Omniverse to create more photorealistic visualisations. “The digital twin is physics-based. It doesn’t just look like the real thing, it behaves like the real thing,” claimed Siemens CEO Roland Busch. “This is not about animation but simulation. If you don’t mimic the real world accurately, you don’t get the benefit out of it. The digital…

‘Mammoth’ direct air capture facility under construction in Iceland

With a nominal carbon capture capacity of 36,000 tons per year when fully operational, Mammoth represents a significant step in Climeworks’ plan to scale up its operations to deliver gigaton capture capacity by 2050. Construction is expected to last 18-24 months before operations start. The firm’s first direct air capture plant, which it claims is 1,000 times more efficient than photosynthesis, was built in Switzerland and went live in 2017 . It has previously sold its services to the likes of Shopify which used the carbon captured by its facilities to offset its own emissions. Climeworks said the Mammoth plant will capitalise on rising market demand, with several 10-year offtake agreements signed over the last months. Preparatory work at the site has already begun…

UK’s first mass-produced hydrogen truck unveiled

Truckmaker Tevva has launched the first hydrogen fuel cell-supported heavy goods vehicle (HGV) to be manufactured, designed and mass-produced in the UK. The hydrogen fuel cell system has been integrated into the firm’s battery-electric HGV design, enabling the hydrogen to top up the battery in order for the truck to carry heavier loads over longer distances. As a result, the 7.5-tonne hydrogen-electric truck can be driven for up to 310 miles, according to Tevva. “When a zero-emission truck is doing more miles per day, that is very good for the air we breathe, for the planet and for the economics of running electric trucks,” said Tevva’s CEO and founder Asher Bennett. “Every mile you drive on an electric truck, it’s so much cheaper than driving on a diesel truck.” …

EU countries reach agreement on climate pledge

After more than 16 hours of negotiations, environment ministers from the European Union's 27 member states have reached an agreement on five laws from a broader package of measures aimed at ensuring a 2035 phase-out of new fossil-fuel car sales and providing financial support to shield poorer citizens from the costs of carbon dioxide emissions. The new climate rules are expected to reduce EU carbon emissions by at least 55 per cent in 2030 compared with 1990 rather than by a previously agreed 40 per cent. “The climate crisis and its consequences are clear, and so policy is unavoidable,” said EU climate policy chief Frans Timmermans. Some of the core parts of the package presented were first proposed by the European Commission last summer, including a law requiring new cars sold in the…

UK ‘urgently’ needs to regulate biometric technologies, warns review

New laws governing biometric technologies are “urgently needed”, Matthew Ryder QC has found, as part of the conclusions of an independent review commissioned by the Ada Lovelace Institute. The use of biometric data - including faces, fingerprints, voices, DNA profiles and other measurements related to the body - is becoming increasingly common in new technologies, particularly those related to facial recognition. However, the review has ruled that the legislation currently in place in England and Wales has "not kept up" with developments in this technology, finding it to be "fragmented" and "unclear" regarding its use. Among the legal review’s ten recommendations are that public use of live facial recognition (LFR) technology be suspended pending the creation of a legally binding code of…

Government’s net-zero plans exhibit ‘major failures’, report shows

In a 600-page assessment, it found that while policies are now in place for most sectors of the economy, there is “scant evidence” that the UK will achieve any of its climate change goals so far. UK emissions are now almost half (47 per cent) their 1990 levels. Emissions rose 4 per cent in 2021 as the economy began to recover from Covid-19 but were still 10 per cent below 2019 levels. While efforts to boost renewable energy deployment and increase uptake of electric vehicles were found to have progressed, other low-carbon options remain “in their infancy”, the report said. Home energy-efficiency was one area found to lacking, especially considering soaring energy prices, which have dominated household bills in recent months. While the government promised significant public spending on…
