Women’s relationship to the environment is shaped by their social position.
New developments in microalgae cultivation are helping to propel the potential of renewable biofuels to combat climate change.

Our research identified three key lessons.
Tiny fuel cells convert sweat to electricity that can power sensors in electronic skin.
Yu et al., Sci. Robot. 5, eaaz7946 (2020)
Lightweight, flexible materials can be used to make health-monitoring wearable devices, but powering the devices is a challenge. Using fuel cells instead of batteries could make the difference.
As the notion of flight shame is taking off around the world, emissions from aviation are making a small but growing contribution to global warming.
Oil palm fruits harvested in Malaysia.
Palm oil production is a leading cause of deforestation in Asia, but an EU ban may make matters worse.
FaHyence hydrogene filling station in action.
The development of a hydrogen charging station has made it possible to run vehicles without producing greenhouse gases.
Algae could be the key to a new type of biofuel.
The right kind of algae can be converted to biofuel, and there are potential side benefits for carbon capture.
The climate change-mitigating dream turns out to be a green damp squib.
Papyrus can alleviate pressures on native forest ecosystems.
The capacity of woody biomass to provide the energy requirements for sub-Saharan Africa is declining. Papyrus wetlands are a sustainable source of biomass that holds potential to substitute for wood.
Millions of tonnes of food go into landfill each year.

Australians send about 4 million tonnes of food waste to landfill each year – but what if we could use it for other purposes?
Blue Mallee leaves in a plantation. The white dots are oil globules.
Eucalyptus oil is useful for lots of things – what if that list also included carbon-neutral aviation fuel? Chemistry suggests it could.
Microbes can survive in the frozen coastal desert soils of Antarctica’s Miers Valley.
Microbes have the ability to survive in extremely hot and cold conditions. This makes them invaluable tools for research: they can teach us how life has evolved and how we survive.
The economics of making biofuels from algae no longer add up, but a lesson from the oil industry could make them viable.
Proper management of Africa’s savanna regions is crucial for the continent’s climate and food security future.
Africa’s savannas provide high potential for farming development but this needs to be done in a smart manner to not worsen climate change.
Still a lot of good under the hood.
Current clean diesel technology is more than capable of meeting tough air quality rules while still delivering excellent fuel performance. Biofuels could make it even cleaner.
An ancient form of energy: a wood pellet manufacturing facility in upstate New York.
The future of two key energy policies – the EPA’s Clean Power Plan and Renewable Fuel Standard – will decide whether bioenergy will continue to grow in US or not.
The vivid pink pools of Western Australia’s Hutt Lagoon are the world’s largest algae farm.

We have the technology to make oil from algae, rather than digging up crude oil from organisms that lived billions of years ago. But bringing it to market will take a force of economic and political will.
What if jet fuel could be grown sustainably?
What if you could grow biofuels on land nobody wants, using just seawater and sunlight, and produce food at the same time?
The Western Treatment Plant in Werribee, Victoria, largely powers itself using biogas – a by-product of sewage treatment.

Could what we flush down the toilet be used to power our homes? Thanks to biogas technology, Australia’s relationship with organic waste – human and animal excreta, plant scraps and food-processing waste…
