The world runs on energy, so finding low-emission alternatives to fossil fuels is crucial. Wind and solar are cheap and abundant but can’t do everything. But hydrogen fuel could complete the picture.
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.
The use of fossil fuels has to end and be replaced by sustainable energy as quickly as possible. The Paris Agreement was a good start but states continuing to work together is key.

The federal government claims that Australia’s rising emissions are offset by savings around the globe when Australian gas exports replace other fossil fuels. But the numbers don’t stack up like that.
Only a small share of the vehicles Americans buy are electric. Even if all of them were, it would take until 2040 to phase out the fossil fuels used to power personal travel and road-bound freight.
Australia’s government insists it is on track to surpass its emissions reduction commitments under the Paris Agreement. But while that may be true, it will only happen with some clever accounting.
A new pathway for the global energy transition shows how the world can meet the Paris Agreement’s 1.5C warming goal without relying on carbon capture and storage, by creating a renewable gas industry.
Indian mining firm Adani has announced scaled-down plans for its planned Queensland coal mine, which it will now fund itself. But there are still many questions hanging over the project.
