If Tesla Energy has its way, these big batteries will soon help power businesses and utility companies across the country. Reuters

Is climate policy compatible with Tesla’s battery‑fueled dreams?

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…

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.
With rooftop solar installations soaring, utilities are nervous – for a few reasons. Greens MPs

Why rooftop solar is disruptive to utilities – and the grid

Electric utilities want to quash distributed solar because they don’t want the competition, right? Perhaps, but if you rely at all on the grid, you have a stake in this fight, too.

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.
Renewables or oil? The former means betting each-way on energy storage. The latter means hoping to pull off a trifecta on carbon storage. Hans Engbers/Shutterstock.com

Only a mug punter would bet on carbon storage over renewables

The question of whether the future will be powered by coal and oil or by renewable energy is crucially important, both to the medium-term future of the Australian economy and to the long-term future of…

Chile’s mines set hot pace on renewables — Australia take note

Mining is the fourth-largest energy consumer in Australia, using roughly 10% of Australia’s total. Some of this comes from the electricity grid — but much is supplied offgrid in the form of diesel and…

Here comes the sun: explosion in solar power beckons

Is solar power the technology of the future? It is certainly the fastest-growing energy generation technology in the UK. By the early 2020s, according to a new report, it will be cost-competitive with…
Roof-top solar panels are just one part of the micropower revolution. Presidency Maldives

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…
Plants use photosynthesis to build molecules and energy they can use. By copying plants, humans can make cleaner fuels. Ranjit Bhatnagar/Flickr

To shift away from fossil fuels, we need to copy plants

Most of the energy that fuels our lives comes from plants. Whether it is a fossil fuel that was formed hundreds of millions of years ago or the food we eat, all carbon-borne energy has its ultimate origins…
A cloud is hanging over Australia’s renewable energy industry after the government’s review recommended that the Renewable Energy Target be scaled back. Leon Brooks/Wikimedia Commons

Renewable Energy Target review – experts respond

The review of Australia’s Renewable Energy Target (RET) has recommended deep cuts to the scheme. If implemented by the government, the changes could mean closing off the scheme to new large-scale wind…

How does the Renewable Energy Target affect your power bills?

The review of the Renewable Energy Target is due to be handed to the federal government any day now, yet amazingly there are still conflicts over whether the policy makes electricity more or less expensive…
Layers of cool: a thin layer of glass added to solar cells could help them work better for longer. Minoru Karamatsu/Flickr

More efficient, durable solar cells are possible thanks to glass

Self-cooling, longer lasting and more efficient solar cells are within reach simply by adding a thin layer of glass. A paper published today in the online journal Optica outlines a possible solution for…
