Real hot: the Ivanpah solar power plant and others like it use mirrors to produce heat to make steam and drive an electricity turbine. BrightSource Energy

If a solar plant uses natural gas, is it still green?

The massive Ivanpah solar power plant uses natural gas – even more than it expected last year. It's not ideal, but solar power and natural gas are a powerful, and relatively 'green,' combination.

Can we expand solar power dramatically without damaging protected lands?

Study shows that many of the utility-scale solar power plants in California have been placed near protected and environmentally sensitive lands.
To no one’s surprise, a US study found that solar panel cells produce infrasound and low frequency noise which is way below audibility. AAP/Dean Lewins

Infrasound phobia spreads … to solar energy cells! What’s next?

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…

Do we need a solar power technology breakthrough?

Hillary Clinton's renewable energy plan is ambitious but, on a technical level, doable. Would it foster more solar technology innovation?
Solar thermal technology is still an outside bet - and not the kind of investment the CEFC was set up to make. WorleyParsons/AAP Image

The Clean Energy Finance Corporation is meant to back winners, not minnows

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.

Coal closures give South Australia the chance to go 100% renewable

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.
With rooftop solar installations soaring, utilities are nervous – for a few reasons. Greens MPs
