Natural gas is touted as a “bridging fuel” to displace coal while moving to a low-carbon economy. In New Zealand, this is shortsighted and could lead to stranded assets and hold back renewables.
Trump administration rollbacks dominated news about the environment in 2017 – but beyond Washington D.C., many researchers are developing innovative visions for a greener future.
Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney’s backyard add up to a zero-carbon energy solution for the city.
Scientists have engineered sugarcane to increase its oil content and are developing renewable jet aircraft fuel from the oil. The engineered sugarcane could become a valuable energy crop.
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.
The great dream of cars running on sustainable petrol has not bitten the dust. Here’s why.
Bio-prospecting is the search for useful materials from natural sources. A biologist explains what we can learn from bacteria about breaking down plant material, and how we can use that knowledge.
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.
A new study challenges the longstanding view that biofuels are carbon-neutral, and asserts that in the U.S. to date, they have done more harm to the climate than gasoline.
A fight’s breaking out over who should pay subsidies for corn ethanol, and it is consumers who may end up paying for any changes.
Australians send about 4 million tonnes of food waste to landfill each year – but what if we could use it for other purposes?
Eucalyptus oil is useful for lots of things – what if that list also included carbon-neutral aviation fuel? Chemistry suggests it could.
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.
The airline industry’s promised technological solutions have not arrived, and they never will.
Obama’s proposal to add $10 tax to crude oil raises the thorny question of whether the U.S. can continue to fund its highway infrastructure with a fuel tax that hasn’t changed since 1993.
Ted Cruz opposes subsidies for biofuels and still managed to win in ethanol-friendly Iowa. Is corn ethanol starting to lose its political clout?
International development banks are supposed to ensure adherence to human rights in the projects they fund. Instead, their practices provide fertile ground for human rights abuses.
