Mining has not been particularly lucrative for New Zealand. It makes little economic sense to focus on digging for minerals, despite claims the new mines will aid in the country’s green transition.

There’s no mention of nuclear in Australia’s latest energy transition roadmap – because our energy market operator can only model power sources legal in Australia.

The Coalition is sending mixed messages on community consultation when it comes to nuclear power. If the community never has the authority to influence the outcome, is it actually “consultation”?

Last week, Victoria’s main gas storage facility was worryingly low. It’s another sign of the flaws associated with leaving gas supply to the market Samantha Hepburn, Professor, Deakin Law School, Deakin University Licensed as Creative Commons – attribution, no derivatives.

A campaign fought on climate and energy might benefit the Greens and the Teal independents – but the prevailing state of the economy will determine their ability to capitalise.

We know some marine microbes produce enzymes that can break down certain types of plastics. But new research found areas of high plastic pollution don’t show high concentrations of these enzymes.

The Coalition’s nuclear plan is an unwelcome proposal which will slow the energy transition and increase our dependence on gas – a surefire way to drive up energy bills. Tony Wood, Program Director, Energy, Grattan Institute Licensed as Creative Commons – attribution, no derivatives.

Victoria’s government wants local governments to speed up development and get more homes built. But there are many questions around this goal. David Hayward, Emeritus Professor of Public Policy, RMIT University Licensed as Creative Commons – attribution, no derivatives.

Offshore wind power can play a starring role in Australia’s future energy mix. It sure beats nuclear and coal, offering advantages in scale, availability and proximity to both users and the grid.

Going nuclear in Australia would mean overcoming a set of almost impossible obstacles, from legal to financial, regulatory and workforce. Ian Lowe, Emeritus Professor, School of Environment and Science, Griffith University Licensed as Creative Commons – attribution, no derivatives.

Hybrid vehicles are having a real moment in Australia and overseas. The problem is, they’re not as clean as we think. Hussein Dia, Professor of Future Urban Mobility, Swinburne University of Technology Licensed as Creative Commons – attribution, no derivatives.

The Coalition’s nuclear policy announcement leaves many burning questions. Exactly what kind of reactors will be built? Who will build them? And how much they will cost?
