The temperature of the Sun’s surface is about 6,000°C. But higher above the surface, in the atmosphere, it suddenly shoots up to more than a million degrees!

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.
Keeping global warming under 1.5°C 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.
How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?
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.
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.
Ethiopia, Sudan, Egypt and their neighbours could deploy large-scale solar and wind farms, connected by a regionally integrated power grid.
A mix of wind, solar photovoltaics, and some natural gas would be more cost-effective than Inga 3 for South Africa and the DRC.
Some coal workers have the right skills and work in the right location to get a job in renewables. But many, such as semi-skilled machine operators, cannot.
Increased business lobbying for incentives and mandates may tip the balance in favor of a cleaner US energy policy.
Renewables technology already exists, it’s getting cheaper and we will never go to war over sunshine. If you need to be convinced of the potential of wind and solar, read this.
How indoor solar cells could help power the Internet of Things.
Environmentalists say the new film has caused untold damage at a time when change has never been more urgent. So why is it so controversial?
A new nuclear plant called Barakah is nearing completion in the UAE. But it risks further stabilising the volatile Gulf region.
Sun Cable could provide Australia an alternative to the export business of coal and gas, and even reduce our export dependence on China.
The transformation of the national electricity market has “progressed at a remarkable pace and scale” over the last year as it moves towards renewables, but security remains a critical issue.
Drought-driven humanitarian emergencies can be prevented if groundwater is reliably made available at strategic locations.
Unpacking what South Africa’s new energy plan says about nuclear energy.
Australia’s renewables revolution proves that there’s cause for hope in our emissions reduction goals. But we cannot rest on our laurels.
Tapping just 3.7% of solar potential in countries in China’s intercontinental infrastructure programme could power the entire region.
