SA Liberal Party leader Steven Marshall said that state Labor policy had left South Australians with 'the highest energy prices in Australia' and 'the least reliable grid'. Is that right?
The proton battery, connected to a voltmeter.
A new rechargeable 'proton battery' - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
More blue sky thinking could help the grid get even smarter.

'Virtual power plants' offer extra power to the grid by tweaking the operation of batteries and appliances right across the network. But even this might be too blunt a tool for our future energy needs.

The fossil fuel era won't last forever. And a new set of countries will find their reserves of lithium, copper and rare earth metals are in high demand.
Keeping the lights on has always been a stormy issue in South Australia.

Two decades ago, the then SA premier, John Olsen, defied a campaign promise and announced plans to privatise the state's electricity industry. It's been a high-voltage issue ever since.
Looking through semitransparent cells – one day these could be big enough to make windows.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Water treatment plants can’t afford not to think about electricity too.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
The European Investment Bank's funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
Puerto Rico’s power utility, PREPA, has been decimated by years of scarcity and bad management. But will privatizing it really turn the lights back on for Puerto Ricans?

Many Puerto Ricans are happy to see their broke power utility sold off to whoever can get the lights turned back on. But privatizing the island's energy grid may bring more problems than relief.

Critical thinking is of paramount importance, especially as it applies to research on the internet -- and to our energy future. Educators have a duty to ensure students avoid fake news on energy.
The Loy Yang power station ‘tripped’ early in the year, triggering fears of a summer of blackouts.
February is the riskiest time of the year for blackouts, as the nation returns to work and school and soaring temperatures put pressure on the system.
Fill a tank with water, sugar, and old mobile phones. Add bacteria and stir. Result? Rare earth metals. This is biomining, and it's the way of the future.
Now that panel costs in U.S. will go up, will reflectors make a comeback?
Joshua M. Pearce
Raising the cost of solar panels coming to the US could rekindle interest in a simple but potentially significant technology: solar reflectors.
Sights like this Brooklyn rooftop covered with solar panels with a view of the Manhattan skyline have become more commonplace amid a U.S. renewable energy industry boom.

Slapping duties on imported panels is unwise.

If China becomes the global leader in renewables it will have huge influence across the world.
The home biogas system offers a zero-emissions alternative to paying for fossil gas.
Australians love cooking with gas, but what if you could make your own supply, using leftover food waste? It may be time for more households to embrace home biogas – and stop paying gas bills.
Unsurprisingly, the Japanese feel ambivalent about nuclear power, but part of their energy needs could be answered by the country's tidal potential.
Blockchain technologies could help homeowners sell their green electricity to their neighbours.
Blockchain technology could be applied to our energy grids to make them smarter, and turn energy consumers into producers.
