Energy storage is crucial, but it’s not the only piece in the puzzle

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.
Amid the fanfare over the launch of the Powerwall, has Tesla’s Elon Musk struck a decisive blow for renewable energy? YouTube/Tesla Motors

The Tesla battery heralds the beginning of the end for fossil fuels

Tesla’s new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.

Energy White Paper promises privatisation and lower prices: experts respond

The federal government’s keenly awaited Energy White Paper is firmly focused on cutting prices and red tape, and boosting industry competitiveness - and less so on climate change and renewable energy.

Get more out of your solar power system by using water as a battery

Most solar power households feed excess electricity back into the grid, for very little financial reward. A hot water heat pump could put that power to better use, by heating water for evening use.
CSIRO’s solar-concentrating mirrors can be used for several purposes, including creating high-energy ‘SolarGas’. CSIRO

Australia should export more ideas and fewer greenhouse emissions

As climate negotiators meet at the United Nations’ Lima summit, which comes hot on the heels of the landmark US-China climate deal, there is a renewed focus on how the world can move to a lower-emissions…

Move over big power – the micropower revolution is here

There is no shortage of shouting and dire warnings about the state of the climate and our need to phase out fossil fuels. But there is a more silent revolution happening too — in micropower. Small-scale…
The government knows that solar panel subsidies are very popular with voters. zstock/Shutterstock

The pitfalls of using renewable energy as a political football

Federal industry minister Ian Macfarlane has finally revealed his opening gambit on negotiations on the future of the Renewable Energy Target (RET). He and environment minister Greg Hunt have pledged to…
While Australians love Michael Leunig’s whimsical ducks, there’s another ‘duck’ pushing your power bills higher. Used with permission from Michael Leunig

Slash Australians’ power bills by beheading a duck at night

Rooftop solar power has slashed Australians’ demand for electricity during the day, but left evening peak power demand largely unchanged. That’s why, as strange as it may sound, we now need to behead a…

Flat lenses could boost solar power

Micro-machining technology could be used to produce flat lenses which would boost the productivity of solar panels. The Fresnel…

Lomborg’s criticism of current renewables is years out of date

The Intergovernmental Panel on Climate Change’s Fifth Assessment Report paints an authoritative picture of the dire consequences if we fail to rapidly curb our greenhouse gas emissions. Solving this will…

How do we get to the next million solar roofs?

There are now one million Australian homes with solar electricity. That means 2.5 million Australians now rely on solar power – more than the population of Brisbane. Australians have clearly shown their…

International spat over solar must not turn into trade wars

Manufacturers and politicians embroiled in the dispute between China and the EU are closely watching the looming deadline of June 5th. By then the European Commission must conclude its provisional anti-dumping…

New silicon to improve solar panels

Solar engineers have developed a method to improve the quality of low-grade silicon, which promises to significantly improve…
