Affordable batteries for green energy are closer than we think

At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…

AUDIO Q&A: What’s in and out of Palmer’s climate strategy

In a surprising announcement last night Clive Palmer promised to abolish Australia’s current carbon price, and block the coalition’s Direct Action policy. But Palmer has said he will vote to retain the…
Time to put some heat into the hydrogen industry. Flames on a black background, Olga Nikonova

Heat subsidies leave hydrogen and fuel cells out in the cold

The inhabitants of a frequently cold and windy country like the UK need to heat their homes, even in what is loosely termed “summer”. This is achieved mostly by natural gas-fed boilers – but this dependence…

Chinese hydropower electrifies southeast Asia, but at a cost

China is the world’s largest energy consumer, its ferocious industrial expansion and urbanisation driving a demand for electricity that has risen 10% in a single year between September 2012-13. This has…

Tapping into the energy that lies deep underground

Geothermal energy is derived from heat produced by the decay of radioactive elements within the Earth’s molten core, where temperatures reach 6000°C around 6000km below the ground. This heat naturally…

Nuclear futures: tough decisions needed to keep Britain’s lights on

Our nuclear reactors have reached the end of their lives, North Sea oil is running out, coal is dirty: Britain faces an energy crisis of rising demand and falling supply. In our Nuclear Futures series…
A bipartisan approach to reducing greenhouse gas emissions is within reach that could ensure the current carbon pricing regime does not need to be dismantled. AAP

Why a bipartisan approach is needed on carbon pricing

The long-term future of carbon pricing in Australia’s efforts to reduce our emissions of greenhouse gases is bleak if there is no bi-partisan approach. With Coalition likely to win September’s election…

Solar thermal energy cost expected to halve: CSIRO

Solar thermal energy will halve in cost by 2020, the new director of the CSIRO’s Australian Solar Thermal Research Initiative said today. Solar thermal energy uses the concentrated heat of the sun to create…
It’s easy to claim “wind turbine syndrome” exists, but where’s the evidence? Snurb

There’s still no evidence that wind farms harm your health

Back in July I wrote an article for the The Conversation arguing that wind turbine syndrome was a classic “communicated” disease: it spreads by being talked about, and is therefore a strong candidate for…
Wind farms have existed in Australia long before the first claims about health ever surfaced. AAP

Wind turbine syndrome: a classic ‘communicated’ disease

At the beginning of this year I started collecting examples of health problems some people were attributing to wind turbine exposure. I had noticed a growing number of such claims on the internet and was…

Australia falls behind in preparation for low‑carbon world

Australia is the only country in the Group of Twenty nations less prepared for a low carbon emissions world than it was almost two decades ago, a report has found. Since 1995, Australia’s reliance on polluting…
