How to get renewable energy into the grid — without losing power

The recent review of the Australian Renewable Energy Target has once again raised the issue of the “unreliability” of some renewable power sources such as wind and solar power. Their variability, which…
Australia does have the capacity to produce more electricity than it needs - but that’s not a reason to scale back the Renewable Energy Target. Indigo Skies Photography/Flickr

FactCheck: does Australia have too much electricity?

We have 9,000 megawatts (nine big power stations equivalent) of excess capacity in electricity generation … We have more than 15% overcapacity in generation in Australia - Industry minister Ian Macfarlane…
This wouldn’t be a problem if propane was renewable. tomsaint

How we tricked E. coli bacteria into making renewable propane

Converting renewable energy into electricity is one thing; converting it into fuel is quite another. The vast majority of global energy demand is for fuel, and a renewable source could help us heat our…

Abbott’s environment agenda is even harsher than he promised

Before the 2013 election, Tony Abbott gave us fair warning that he would turn the clock back on the environment. As promised, his government has devoted itself to short-term economics and the sort of hardline…

Review calls for Renewable Energy Target cuts: what it means

The long-awaited review of Australia’s Renewable Energy Target has been released and, as widely predicted, has recommended winding back or even scrapping the various parts of the scheme. We asked Conversation…
Is the ABC biased against fossil fuels? The IPA thinks so, but it’s not really the most constructive question to ask. AAP Image/Tracey Nearmy

We mustn’t waste water while taking action on climate change

Should we pick and choose our climate strategies based on how water-wise they are? As our new research published in Climatic Change shows, some activities aimed at tackling greenhouse emissions can also…

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…

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…
