Rooftop solar panels: will they kill power companies or can they help them?
Many utilities see rooftop solar as a threat, but solar power can actually lower the cost of power they – and their consumers – need to pay during hours of high demand.
Renewable energy developers choose sunny locations, which can be near protected lands.
Study shows that many of the utility-scale solar power plants in California have been placed near protected and environmentally sensitive lands.
Solar energy is key to development in African countires.
Integrated research is key to sustainable development, which helps Africa resolve its energy woes.
Australia has 1.4 million solar rooftops. But it is with the addition of battery storage that energy grids will really be revolutionised.

New prime minister Malcolm Turnbull has stressed the importance of embracing 'disruptive' technologies that shake up existing business models. Solar power and battery storage is one of the most enticing options.
Australia has some catching up to do to match the rest of the world on large-scale solar.

New funding for large-scale solar could be backing a winner, but only with the right leadership.
To no one’s surprise, a US study found that solar panel cells produce infrasound and low frequency noise which is way below audibility.
Internoise is the world’s premier research conference for acousticians. The 2015 meeting is being held right now in San Francisco. Buried among the hundreds of papers is one that you could easily take…
Will alternate solar technologies get a boost if solar overall grows?
Hillary Clinton's renewable energy plan is ambitious but, on a technical level, doable. Would it foster more solar technology innovation?
Townsville’s roads (pictured) may have their busy periods but is it the best place to start a solar charged ‘electric super highway’?
If you want to kick-start the "electric superhighway" in Queensland then it makes sense to start in a populated area with the busiest traffic.
Is the price right for installing solar panels?
Victoria's solar will soon get a mere 5 cents for power they send to the grid. But is that a fair price?
California has realised that investing in renewables is smart economic policy.

Ramping up investment in renewable energy would put Australia on a footing with competitors such as China, Germany and California, which are set to reap the economic benefits of this emerging sector.
Is the sun setting on Britain’s energy ambitions?
In the long run a shift from renewables to fossil fuels will make it harder to reach emissions targets and will harm the UK's international standing.
Solar thermal technology is still an outside bet - and not the kind of investment the CEFC was set up to make.
Environment minister Greg Hunt wants the Clean Energy Finance Corporation to focus on new technologies, not wind and solar. But that's not what it was set up to do, and Australia already has an agency for that.
Packing heat: concentrating sunlight into a reactor to split H2O and CO2 – a step toward making liquid fuels.

Rooftop solar power is exploding in the US but some scientists are pursuing a radically different route in renewable energy: storing solar energy as a liquid fuel.
South Australia’s wind farms have coped without baseload power before - they can do it again.
Coal closures announced this week in South Australia will cause employment pain, but could also help pave the way for the state to go 100% renewable - something that modelling suggests is eminently possible.

What to make of the announcement that we'll be off the hydrocarbons in time for the 22nd century? Dream on.
What if jet fuel could be grown sustainably?
What if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?
A new Grattan Institute report suggests solar panels in Australia might be more trouble than they are worth.
The Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
Tesla’s lithium-ion powerwall isn’t the only technology available for household batteries.
Lithium-ion is currently the leading battery technology for home installation, but others are just over the horizon that might be even better.
Countries should make pledges to fund low-carbon research - such as developing solar technology - and development as part of global climate talks.

Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
Investment in technologies beyond the existing wind and solar could stagnate in the face of the government’s reduced Renewable Energy Target.
After months of deadlock, a deal has finally been reached to reduce the Renewable Energy Target, ending the uncertainty for industry but also risking an already sparse pipeline of future projects.
