Renewables form an ever-greater share of the electricity mix. But elsewhere in the energy sector – in transport, industry and buildings – emissions reduction is very slow.
When announcing financial penalties on Russia earlier this year, Biden hinted at the prospect of ‘further’ sanctions. An energy scholar explains what Biden may have meant.
Photos from the early 1900s show LA’s forests of oil derricks. Hundreds of wells are still pumping, and new research finds people living nearby are struggling with breathing problems.
None of Australia’s highest-emitting energy firms are fully or even closely aligned with global climate goals. Just one goes even partway, and five appeared to be taking no action at all.
The opportunity won’t last forever. Countries that move first will gain an advantage in new industries, technologies and export markets. Those that wait may never catch up.

Government-owned firms are often branded as uncompetitive, stuck in the past and unable to truly innovate. But they’re sometimes better suited than private firms to drive new, clean technologies.
Scientists are working on ways to make lots of energy by converting matter into energy. The trick is keeping the process under control. One possibility is nuclear fusion – the Sun’s power source.
Building retrofits are no joke: They make dwellings healthier and more energy-efficient. And when they’re done in low-income housing, they also reduce inequality.
On the 10th anniversary of the Fukushima nuclear disaster, two experts explain why human choices are more important to nuclear safety than technology, and why the job is far from finished.
