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…
How selfish! Are solar panels really pushing up the price of power for everyone? Elliot Brown

More solar, less power demand, higher prices: does it add up?

If I install solar panels and a car battery to run my air conditioner, should I pay higher electricity network fees? The electricity industry and Queensland’s Energy Minister would say yes, but is that…
It doesn’t matter that wind and solar power are intermittent: the need for base-load power is a myth. Flickr/Eidoloon

Baseload power is a myth: even intermittent renewables will work

The future of civilisation and much biodiversity hangs to a large degree on whether we can replace fossil fuels – coal, oil and gas – with clean, safe and affordable energy within several decades. The…

What’s going on with Chinese solar?

The bankruptcy of Chinese solar energy company Suntech Wuxi is being depicted in the media as a sign of chaos in the solar industry. The industry is said to be suffering from disastrous price falls created…
How do rooftop solar panels work? Abi Skipp

Explainer: what is photovoltaic solar energy?

There are two main types of solar energy technology: photovoltaics (PV) and solar thermal. Solar PV is the rooftop solar you see on homes and businesses - it produces electricity from solar energy directly…

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…
It’s time to take solar transport fuels a lot more seriously. National Renewable Energy Lab

Here’s to hydrogen: Australia is missing the potential of solar fuels

Many times in human history governments have tried to write policies based around future technologies and missed identifying the transformational keys. In the 1970s, for example, few if any horizon-scanning…
Things go wrong when prices are out of whack. Kevin Baird

Set reasonable PV feed-in tariffs, or expect perverse outcomes

Contrary to expectations, demand for electricity in Australia has been falling for several years. Reasons for this include large price rises (of which the carbon price is a relatively small component…
Australia could soon have millions of small electricity generators. absentmindedprof/Flickr

Energy White Paper underestimates solar

The 2012 Energy White Paper has much to commend it. In particular, the far greater acknowledgement of the need to shift to clean energy sources is a fundamental shift from previous White Papers. The emphasis…

‘Invisible’ fish could light the way to better optical devices

Imagine setting up mirrors in a circle around you, the shiny sides all facing outwards to reflect your surroundings. To the casual observer you would appear to be “invisible”, blending into the environment…
Wind and solar power appears to have been behind a drop in wholesale power prices in South Australia, leading to a proposal to reduce retail prices for consumers.

Power of the wind - how renewables are lowering SA electricity bills

Renewable energy sources such as wind and solar power appear to be the impetus behind a South Australian proposal to substantially drop electricity prices, just as other states are hiking theirs. The Essential…
The Climate Commission says Queensland could be a leader in concentrated solar thermal power, but the political will is lacking. AAP

Qld a leader in solar? Not under current govt, say experts

Around the clock solar power could be a reality for Australians in the foreseeable future, but experts say a hostile state…
Sunlight falls equally on leaves and solar panels, but which does the best job of turning it into useful renewable energy? kincuri/Flickr

For efficient energy, do you want solar panels or biofuels?

About 80% of the world’s total energy consumption is derived from fossil fuels, with only 12.5% from renewable resources. Replacing fossil fuels with renewable energy sources derived from sunlight - such…

Australia under a carbon price plan: Q+A with Ross Garnaut

Tomorrow Australia will place a price on carbon. The former climate change adviser to the Federal Government, Ross Garnaut…
A cleaner, more efficient Australia will blend smart grids and meters with renewable power’s growing capacity. Pictured: Spain’s Gemasolar concentrated solar thermal power plant. Gemasolar

Challenge 13: smart energy demand and renewable supply

In part 13 of our multi-disciplinary Millennium Project series, Mark Diesendorf argues that it is high time we got smart about power: how we generate it and how we deliver it. Global challenge 13: How…
Do you see the light? Solar costs are comparable to fossil fuels, and are falling 45% annually. Flickr/MyEye85

Newsflash: solar power costs are falling below fossil fuels

Recent postings to The Conversation have enlivened the debate over the “Great Transition” that is underway all around the world from the fossil-fuelled energy systems of the 20th century to the renewably…
Lack of political will is holding back Australia’s solar innovation: here, AREVA Solar’s CLFR technology. Solar Dawn

Serious about renewables? It’s time to refloat the Solar Flagships

Australia knows how to provide public leadership in the complex coordination of public events. Just look at the recent staging of the opera La Traviata on Sydney Harbour. It was a one-off event that required…
