The process of manufacturing gallium-doped solar panels was under a patent until last year. It’s only now that this method has started to pick up steam.
Nearly 60 years after a radiation-leaking reactor was removed from a US Army base on the Greenland ice sheet, the military is exploring portable nuclear reactors again.
Hybrid energy systems that combine renewable and non-renewable fuel systems could be the key to sub-Saharan Africa’s energy transition.
Keeping global warming under 1.5℃ is still achievable with rapid deployment of renewables. A new report found solar and wind can supply the world’s energy demand more than 50 times over.
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.
How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?
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.
Chinese bitcoin mining could consume as much energy as the whole of the UK by 2024.
Firewood and charcoal are replaced with more energy-efficient electricity.
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.
As global oil consumption drops, oil companies are pivoting to petrochemicals, and could crowd out bio-based alternatives.
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.
The maintenance required for renewable tech like windfarms can harm the environment. Robots are helping solve that.
Fireflies’ summer evening light shows are a delight for humans, but for the insects they are a crucial mating ritual – and human-caused light pollution is a buzz kill.
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.
Why do nuclear plants produce radioactive water – and what happens when that water gets into the ocean?
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.
Low-carbon alternatives for steelmaking are numerous – but which will be ready in time?
