Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
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.
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.
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.
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.
We can't decarbonise the whole transport sector with just batteries - sustainable fuels are essential.
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.
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.
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.
Academic experts on how the humble car could evolve to become an unlikely hero in the global fight against climate change.
To become an attractive prospect for electric car manufacturers, the UK needs to sort out its supplies of rare earths – Brexit, or no Brexit.
Electricity consumption will grow as more people switch to electric cars – but this could drive up emissions, unless power is sourced from renewables.
When it comes to eliminating greenhouse gas emissions from transport, the future is already here on small islands.
The year 2030 may not seem far away, but a decade is a long time in technological terms. Widespread automation, electrification, and connectivity are set to revolutionise the car of the future.
Chinese electric vehicle sales already amount to more than half of the world's total – and car makers and battery manufacturers are working hard to grow even faster.
Vehicles in Canada are big, heavy and guzzle a lot of gasoline.
Electric motors are used in everything from utes to mining trucks – because they pack plenty of oomph.
Putting driverless cars on the road safely is hard enough. Doing it in the air is much more difficult.
Concerns about the strain electric cars can put on the electricity grid are not unfounded, but there are some relatively simple fixes available.
