A big spill in Michigan's Straits of Mackinac could have devastating consequences. But does replacing the pipeline running beneath it make sense in a warming world?
The spix macaw is considered to be extinct in the wild.“
Rapid environmental decline is a major threat, yet education is not mobilised to empower children. Fortunately, many initiatives explore how to make students actors of the ecological transition.
Hydrogen fuel is just one opportunity for Australia in a clean-energy future.
The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.

A new law provides flexibility in terms of how the state can meet this new target for the electricity it consumes.

Digitalisation and better energy storage are reshaping the electricity market.
Could this be the way to fill up in future?
The hydrogen economy has been touted for decades as a way to navigate the clean energy transition. Now a new CSIRO roadmap sets out how hydrogen power can become a major energy player.
Most garages can double as EV charging stations.
As EVs make more inroads, giving tenants somewhere to plug in their cars could become a selling point.
Is the sun setting fast enough on coal-fired power?
Australia needs to accelerate its transition to clean energy, and not prolong the use of high-polluting, coal-fired infrastructure. Otherwise it risks missing out on an economic windfall.

Environmentalists and climate hawks are cheering, but many experts aren't excited about the state making rooftop solar panels mandatory on most new homes beginning in 2020.
Tesla is installing one of the world’s largest solar arrays at its Gigafactory 1 in Nevada.
Will the renewable energy transition end up creating yet more greenhouse emissions, as we ramp up the manufacture of wind turbines and solar cells? Not if their manufacture is itself powered by renewables.
Solar photovoltaics are now the world’s leading source of new electricity generation.

Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
Grid-scale energy storage systems may make it easier to rely completely on renewable energy.
Saving power to use later lets consumers, businesses and utilities generate energy when it's cheap and deliver it when they need it most. There's not much of it today, but the industry is growing fast.
Looking through semitransparent cells – one day these could be big enough to make windows.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Most of the growing number of jobs in the solar industry have more to do with maintaining and installing panels than manufacturing them.
The Trump administration can boost domestic solar panel manufacturing without slapping duties on all imports.
Managed in the right way, wind farms can actually help stabilise the grid, rather than disrupting it.

New modelling suggests that Australia could use renewable energy to hit its 2030 emissions reduction targets, without it costing any more overall than maintaining the status quo.
Transportation is the biggest contributor to greenhouse gases by sector. Converting the U.S. fleet to cleaner electric vehicles would likely take decades.

What if the world really got serious about meeting global climate goals? Doing the math on current emissions and the pace of energy transitions shows how quickly fossil fuels need to be phased out.
The new energy policy could potentially function to preserve black coal’s place in the energy mix.

The National Energy Guarantee proposal seems geared towards locking in the status quo rather than driving the much-needed energy transition.
The new policy could end up feeding demand for coal.

By rebranding coal as 'dispatchable', the government's National Energy Guarantee looks set to preserve demand for coal-fired power by giving it a new role – one it's not well equipped to fulfil.
Business as usual is not an option.
A new CSIRO roadmap outlines the options for oil and gas companies to keep pace with the clean energy transition, including solar-powered hydrogen fuel production.
Yes, but who’s directing energy policy?

We have learned a lot in the year since South Australia's lights went out, and have made some useful early reforms. But the energy sector and politicians need to chart a much steadier course in future.
