Its plan to stop lending money for oil and gas projects embraces the spirit of the Paris agreement at a time when the U.S. is going in a different direction.
The home biogas system offers a zero-emissions alternative to paying for fossil gas.
Australians love cooking with gas, but what if you could make your own supply, using leftover food waste? It may be time for more households to embrace home biogas – and stop paying gas bills.
A storm is brewing.
There are some huge issues at stake – and many of them are being ignored.
The Victorian government is aiming to boost renewable energy to 40%.
Victoria's plan to legislate its own renewable energy target of 40% by 2025 shows how states are increasingly taking the energy policy reins away from the federal government.
Disruptive technology, Ming Dynasty-style.
In pulling out of the Paris climate agreement, Donald Trump has turned his back not just on the world but on the low-carbon economy. He should pay heed to a very apt lesson from China's history.
This array in Indiana is one of a growing number of “community solar gardens” in the US.
Without help, lower-income people could miss out on the clean energy revolution – hence the arrival of community projects aiming to boost access to solar panels, batteries and other green technology.

Levulinic acid is derived from plants and can be used to make everything from pharmaceuticals to plastics.
The drop in oil has not sparked the nadir of green energy.
Contrary to economic theory, data shows that the latest drop in energy prices does not undermine investment in renewable energy.
Both electric cars and renewable energy stand to gain significantly from cheaper storage.
Battery prices are falling faster than anyone expected: that's good news for solar power and electric cars.
Wind farms like this one probably wouldn’t exist if the government didn’t provide a hefty subsidy.
Congress passed the wind production tax credit (PTC) more than two decades ago to spur development in an industry still in its infancy. The wind sector has since matured into adulthood, prompting thousands…
Electricity from wood? We have the power.
When we think of renewable energy, it’s easy to picture spinning wind turbines or rooftop solar panels. But what about bioenergy? While wind and solar are now well established – in South Australia wind…
Battery costs can make up a quarter of the cost of an electric car such as this Tesla Model S.
At the heart of the current debate around energy is the question of storage. In cars, how to build batteries that run for hundreds of kilometres; in electricity, storing energy from solar panels for when…
