Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S. Shal Farley/Flickr

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…
Water storage is used to smooth the output from hydroelectric power - but it can be used with other renewables too. Martin Kraft/Wikimedia Commons

How pushing water uphill can solve our renewable energy issues

More and more renewable energy sources are being plugged into Australia’s electricity grids. South Australia, for example, will get 40% of its electricity from wind and solar once the Snowtown wind farm…
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…

Litany of deep cuts for environmental programs

Budgets are often framed as give and take. But in the case of the environment, the government is taking large amounts of money in cuts, while giving little back beyond funding the Direct Action climate…

Renewable energy target can go all the way to 100% – if we let it

The political outlook for renewable energy is not great – and I’m not just talking about the view out of Joe Hockey’s car window. The Renewable Energy Target (RET), which aims to deliver 41 million megawatt-hours…
Automatically labelling people as NIMBYs if they have concerns about local power projects is not a constructive way to proceed. Grahamec/Wikimedia Commons

Calling people NIMBYs won’t stop development arguments

From coal seam gas to wind farms, new resource projects seem to be pitting communities against corporations, and people against their neighbours. We often see, in such cases, community concerns labelled…

Solar power can bring a bright energy future – even in the UK

The UN’s Intergovernmental Panel on Climate Change reports has once again called for a “massive shift” to renewable energy. The challenge of curtailing anthropogenic greenhouse gas emissions is considerable…
Will transmission charges cloud over Germany’s solar industry? Ben Birchall/PA

Grid access tax may cost more in lost renewables than it earns

Germany, one of the world’s leading users of solar power, is set to charge people generating their own solar-powered electricity for access to the national grid. The move is part of the package of reforms…
If power can’t come to the village, the village must make its own. AbuBakr Bahaj

Solar power is the only answer to light up rural Africa

It is estimated that around one and a half billion people globally have no access to reliable electricity. Most live in developing countries where the cost of connecting rural villages to the electricity…
Solar is taking off in Australia’s suburbs, but what are inner-city livers to do? Duncan Rawlinson

How will your energy get greener? Depends where you live

In Australia’s middle and outer suburbs, rooftop solar technology provides a clear way to reduce the emissions from the energy our houses use. But higher density housing types (apartments and medium density…
When it’s hot, the sun is shining. That’s good for solar power. Flickr/jimwhimpey

When the sun don’t shine, the power don’t flow … or does it?

Renewable energy seems to be on a roll. One million Australian homes have rooftop solar cells. There’s so much renewable energy it’s reducing wholesale electricity prices. But then, that old chestnut pops…
Regional centres and outer suburbs - not inner-city latte sippers - are leading the solar charge. Duncan Rawlinson

Solar revolution led by outer suburbs

Households across the country are putting solar panels on their roofs at a rate that has exceeded all expectations. This year we hit 1 million rooftops with photovoltaic (PV) solar panels, up from just…

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…
