The UK is about to miss an opportunity if it tries to take on the giants of the lithium-ion battery industry.
The Maguga Dam in Swaziland. Many development challenges of dams are not as clear as critics suggest.
Dams are once again being recognised as important key contributors to a prosperous and sustainable future.
Cultana, South Australia: scene of the nation’s next big hydro scheme?
A planned expansion to the Snowy Hydro scheme is grabbing headlines. But a new plan could build oceanfront hydro power in places without mountains - including South Australia.
With the right mix, the grid can go fully renewable for the same cost and reliability as fossil fuels.
The Turnbull government is funding energy storage as a crucial missing piece of the electricity grid puzzle. Analysis suggests an affordable, fully renewable grid doesn't require any heroic assumptions.
Social media might help you navigate the confusing world of sustainability.
Social media is a great way to to share tips, knowledge and expertise - including about how to reduce the environmental footprint of your home.

If you're worried about rising electricity prices, then going off-grid sounds attractive. But why not create an intelligent network of solar-powerd batteries that can reduce prices for all?
We already have them in many sizes – but we're still looking for a battery to store truly large amounts of energy.
Renewables could benefit from more energy storage capacity in the electricity network.
Energy storage is often considered the holy grail of the electricity sector. Great for households, it could be as important in the wider electricity network.
Michelle Simmons was honoured for her leadership on research into quantum computing.
From researchers into the future of quantum computing to those working on low cost energy storage or explaining why onions make you cry, all were winners in the annual Eureka Prizes.
Graphene could have a radical influence on the future of energy storage.

Something is needed to give the stalwart lithium-ion battery a boost for our increasingly power hungry mobile devices.
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.
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?
Batteries to store excess solar power will be a game-changer. But energy-efficient appliances will mean you can use a smaller battery.

The unveiling of Tesla's Powerwall home battery has been hailed as a huge moment in renewable energy. But don't forget the other innovations that can help you use that stored power more efficiently.
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.
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.
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.
