'Energy productivity' is the new buzz-phrase in energy and climate policy, what even is it?
A concept-only supercar, perhaps, but one that could shake up the status quo.
Will China end up eating the lunch of the current crop of global car manufacturers?
Just because we've got electric supercars, doesn't mean it's the only way to a greener future.
Plugging the gaps.
Allowing infrastructure to take over the job of keeping our vehicles running sends us further down a troublesome road.
Tesla owners with clever license plates: W/O GAS, TSLA 101, SUN ENRG, and SIN CO2.
As electric vehicle fans, Tesla's customers are a key cog in the company's marketing machine. How much pull will they have as Tesla makes the Model 3 for a broader – and tougher – crowd?
Looks like a Jag, emits like a Prius.

Townsville’s roads (pictured) may have their busy periods but is it the best place to start a solar charged ‘electric super highway’?
If you want to kick-start the "electric superhighway" in Queensland then it makes sense to start in a populated area with the busiest traffic.
The real world is finally catching up with 1950s sci-fi.
Cars are dirty and wasteful. Large fleets of autonomous taxis could cut emissions and reduce inefficiency.
Time for something new in the battery department.
Everyone wants a better battery for longer run-time on electronics and driving range for EVs. What's the most likely successor to today's lithium-ion batteries?
The Tesla Model S - mean, and green?
The Tesla Model S is only as green as its electricity source - which is not very in brown-coal powered Victoria.
Both electric cars and renewable energy stand to gain significantly from cheaper storage.
Battery prices are falling faster than anyone expected: that's good news for solar power and electric cars.

Solar powered aircraft might carry one pilot in relative discomfort, but don't expect airliners soon.
Not coming to a motorway near you.
It sounds like something from the pages of books from the 1960s looking to the future: electric cars powered by current drawn from electrified rails beneath the road. However possible such ideas seemed…
Fill it up with hydrogen.
In an effort to jumpstart adoption of fuel cell electric vehicles, Toyota Motors earlier this month made more than 5,600 patents available to other carmakers. A few days later, General Motors introduced…
