We calculated what would happen if petrol cars were replaced overnight with Teslas and Nissan Leafs.
Volkswagen's new integration of online and offline sales offers insight into the future of the showroom experience.
A switch to electric transport is one of New Zealand's key climate strategies. It will increase demand on the national grid, but might also help increase renewable electricity generation.
UK efforts to decarbonise transport are due to hit a roadblock.
Transport Secretary Grant Shapps has called for fewer cars and better public transport.

There's still a long road ahead in the electric car revolution. But Australia can learn from New Zealand's policies to boost electric car sales.
The future of British motoring?
It may seem a long way away, but a 2035 ban requires investment and major changes right now.
Changing incandescent light bulbs (right) to LEDs (left) is an example of eco-efficiency, but it can also have unintended consequences.
Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
The car we choose and the energy system we support are linked.
Our power plants may be dirty now. But unlike combustion vehicles, electric cars give us the chance to finally free ourselves from high-carbon travel.
While still new, Tesla’s electric cybertruck has not performed as well is its predecessor, the 2016 Model 3, which got 200,000 orders within a day of being unveiled.
Elon Musk's latest venture has been met with confusion and ridicule. But drawing inspiration from science fiction for new technology should go beyond simplistic futurist fantasies.
Elon Musk is making a big bet with his new Gigafactory near Berlin.
One of the questions I’m asked most frequently is: how can you make sense of Tesla’s wild strategies?
Electrifying transport needs bigger changes than another high-end electric car.
The best way to compare emissions from electric cars is to assess all phases of a life cycle analysis.
In New Zealand, where more than 80% of electricity is renewable, the carbon footprint of electric cars is 62% lower than that of fossil cars. But their lithium battery has other environmental impacts.
Many vehicles can’t just be powered by battery.
We can't decarbonise the whole transport sector with just batteries - sustainable fuels are essential.
Research into low-carbon planes is underway, but we won’t see electric long-haul flights any time soon.

Unlike a car, you can't just stick a battery-powered engine in a plane and expect it to fly. Despite that, small planes might be the future of electric flight.
Governments can choose to spend money in ways that support climate change policy, including a shift to electric vehicle fleets.
New Zealand is introducing new procurement rules to better link government spending with climate change policy. The first target is to reduce emissions profile of the government's vehicle fleet.
Australia and Russia could soon be the last remaining developed nations without fuel efficiency standards, with New Zealand proposing new rules and financial incentives to get more people driving cleaner cars.
New Zealand has proposed new fuel standards, along with a consumer rebates for cleaner cars – paid for by higher costs for high-polluting cars – to cut its rising transport emissions.
