A key ingredient for a green future is currently derived from fossil fuels.
Critical minerals like cobalt, lithium and rare earth elements abound in Australia. But we’re not making the most of these in-demand resources.
Technologies like biomass gasification can help tackle the growing global problem of food waste.
Electric vehicle batteries, wind turbine generators and hydrogen fuel cells are among technologies likely to be affected by the conflict.
Quirks of our geology made Australia unusually abundant in coal. But as the world goes green, we can switch to vital clean mineral resources so coalminers aren’t left behind.
There are myriad benefits to recycling human waste but our reluctance seems to be based on distaste.
Realities on the ground tell a different story from the claim that a Green Revolution ensures food security and increased income for smallholder farmers in Ghana.
The maintenance required for renewable tech like windfarms can harm the environment. Robots are helping solve that.
Rare-earth metals are currently mined or recovered via e-waste recycling — methods with drawbacks including high cost, environmental damage, and risks to human safety. This is where we come in.
A study points to one way to speed up adoption of innovations in clean energy technology – more flexibility among state regulators.
Apple’s newest release comes without a wall charger and earpods. While the shift could reduce the company’s carbon footprint, users shifting to wireless charging will use more energy.
And why development funders should listen to smallholder farmers
Finding out what would motivate people to reduce their carbon emissions can be determined by examining behaviour.
The UN’s climate change conference is coming to the UK this year, and former industrial powerhouse Glasgow is just the city to demonstrate its environmental commitment.
Exploration of ancient magma chambers in fossil volcanoes has the potential to provide new sources of metals that will facilitate environmentally friendly technologies.
The Conservatives’ green investment standards may not have a direct impact on emissions. But with a few tweaks, it could be effective and affordable.
Deep sea mining could supply valuable rare minerals to green technology, but one project in the south-west Pacific is invoking the wrath of local spirits.
The value of green technologies and systems is that they are largely decentralised or semi-decentralised.
Research is yielding strategies for making plastics greener and more sustainable. But without support as they scale up, new versions will struggle to compete with well-established synthetic plastics.
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.
