Where to put the first electric car charge station in the Sunshine State

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.

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.

Solar fuels: how planes and cars could be powered by the sun

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.

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.

Given the value of emissions cuts, solar subsidies are worth it

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.

What’s missing from our climate pledges? Low-carbon R&D

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.

How will the reduced Renewable Energy Target affect investment?

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.

Energy storage is crucial, but it’s not the only piece in the puzzle

The unveiling of Tesla's Powerwall home battery has been hailed as a huge moment in renewable energy. But don't forget the other innovations that can help you use that stored power more efficiently.

The Tesla battery heralds the beginning of the end for fossil fuels

Tesla's new home battery could help halve the costs of electricity for typical American households - all using existing technology. The fossil fuel industry is right to be worried.
If Tesla Energy has its way, these big batteries will soon help power businesses and utility companies across the country. Reuters

Is climate policy compatible with Tesla’s battery-fueled dreams?

Many of the targeted behavioral responses to climate change involve reducing energy consumption. This makes sense as the majority of energy consumed (pretty much throughout all history) has involved burning…
