New prime minister Malcolm Turnbull has stressed the importance of embracing 'disruptive' technologies that shake up existing business models. Solar power and battery storage is one of the most enticing options.
But can you make an EV at half the price of that one?
Elon Musk of Tesla Motors wants to build an affordable, mass-market electric car. What can Tesla learn from another auto innovator – Henry Ford?
Each lump is an effective – if dirty – primary battery.
Fancy new battery technology is great – but still far off the scale required to put a serious dent in carbon usage.

There are plenty of challenges to address before the electric car becomes a practical alternative to the petrol powered cars in Ausrralia.
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?
Low-running batteries are the cause of significant anxiety in modern life.
There are a few simple things you can to do maximise the lifetime of your batteries so they don't need to be replaced as often.
Batteries can cut carbon emissions, but mining the metals and other resources needed to make them can be a dirty business.

The advent of battery storage heralds an even deeper embrace of electric cars and renewable energy. But amid the green tech revolution, we should be wary of creating new pollution problems.
Tesla’s lithium-ion powerwall isn’t the only technology available for household batteries.
Lithium-ion is currently the leading battery technology for home installation, but others are just over the horizon that might be even better.
Fancy a home battery with your battery-powered car?
As it's done with its electric cars, Tesla will need to rely on well-heeled early technology adopters and friendly regulations to sell lots of home batteries.
Elon Musk says the the Powerwall solar charged batteries could take a home off the electricity grid.
Not everyone will get the chance to cut their household electricity bills from solar powered batteries.
If Tesla Energy has its way, these big batteries will soon help power businesses and utility companies across the country.
Many of the targeted behavioral responses to climate change involve reducing energy consumption. This makes sense as the majority of energy consumed (pretty much throughout all history) has involved burning…
Coming to a grid near you.
Batteries combined with digital technologies will improve the efficiency and reliability of the electric grid, transforming how people use their energy.
Batteries have come a long way since their beginning back in 250BC.
Billionaire Elon Musk, the man behind the Tesla electric car, is expected to announce a new generation of battery technology this week. But how did batteries develop in the first place?
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.
Some will come out alive, other will not.

Picture a device that can produce electricity using nothing but the ambient heat around it. Thanks to research published…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S.
At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
Researchers from the University of California have developed batteries powered by silicon extracted from sand, which last…
Uh oh, don’t let US customs see this.
I find international travel tedious. While the destination is always exciting, the journey is simply a chore to be endured. Watching a movie on your laptop or browsing the internet on your phone can make…
