Australia’s abundant wind and solar resources mean we’re well placed to produce the hydrogen a green steel industry needs. But there are technical and economic challenges ahead.
Prominent academics, including a former IPCC chair, round on governments worldwide for using the concept of net zero emissions to ‘greenwash’ their lack of commitment to solving global warming.
The Drax biomass plant in Yorkshire is the first in the world to pioneer carbon capture and some specialists see it as it has a bright future. But hold the rosy headlines.
Torrefaction produces a substance that can be burned like coal.

Deriving fuel from trees costs more than wind and solar power and it emits more carbon than coal. There are many heated debates about this kind of energy, known as forest or woody biomass.
A new report calls U.S. forests an undervalued asset for slowing climate change. It warns that they are being degraded by logging for wood, paper and fuel, particularly in the Southeast.
Farmers are setting fire to their straw and spreading air pollution across northern India.
Wind turbines require massive structures that are polluting to produce and can harm ecosystems, but these impacts compare favorably with those of fossil alternatives.
