Electric car revolution: calculating the cost of green motoring

    Streets will be quieter, the air will be cleaner, people will spend less time at petrol stations and car factories might even return to Britain’s shores if the country switches to electric cars in a widespread fashion. But widespread adoption of battery-powered vehicles would not be without challenges too. A large-scale switchover to electric cars could create problems for power grids, could mean roads lined with charging poles and it could also leave a big hole in public coffers as fuel duty dries up.

    With just over 90,000 fully electric and plug-in hybrid cars now on UK roads, such risks and benefits might look a way off. But this week big changes have been announced. On Wednesday Volvo said it will only launch electric or hybrid cars from 2019 and just a day later Emmanuel Macron’s new government pledged that France will ban diesel and petrol cars by 2040. Battery-powered travel could be coming far sooner than previously thought

    According to research published this week by Bloomberg New Energy Finance the proportion of fully electric new cars sold in the UK will be one in 12 by 2030 – up from one in every 200 today. The surge in electric cars will have to be accompanied by thousands of new charging points to plug them all in. Today there are around 4,000 publicly accessible locations with 13,000 plug sockets. Of the 13,000, a fifth are so-called rapid charging connections that will top up a Nissan Leaf, the UK’s best-selling pure electric car, in half an hour.

    The number of sockets is set to soar to 80,000 by 2025, predicts Zap-Map, which has mapped the ones built so far. There are 8,476 petrol filling stations across the UK, most with many pumps, but topping up takes minutes rather than hours. A lot of those will be installed in supermarkets, railway stations and car parks. But there will be also a lot of poles along residential streets, even though there are other innovative fixes such as the charging sockets a German company is building into street lamps.

Lab-grown meat is on the way

It’s good for the planet, and surveys show that significant numbers of people would be willing to give it a try

    It used to be limited to sci-fi fantasies and futurist predictions: one day, went the story, humanity would discover how to divorce meat production from livestock-raising and simply grow meat without the need for the massive resources it takes to raise farm animals.

    As early as 1894, then-famed French chemist Pierre-Eugène-Marcellin Berthelot claimed that by 2000, humans would dine on meat grown in a lab rather than from once-living animals. Winston Churchill made a similar prediction in 1931, and the idea became even more popular when Commander Riker revealed to an alien on Star Trek: The Next Generation that the meat humans consume on the USS Enterprise was grown rather than slaughtered.

    Today, these science fiction dreams are starting to become science fact. Actually, it was NASA that led the way to making it so, funding successful research 20 years ago that explored whether long-term astronauts could grow meat – since they of course won’t be hauling Noah’s Ark in tow. But it turns out that while it will be a long time before we set off for long-distance cosmic tourism, the technology to create “clean meat” is needed here on Earth far more than it is in outer space.
