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.
Could solar power provide an alternative energy source for the web?

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.
Fire a set of high-power lasers at a tiny speck of hydrogen isotopes and you can initiate nuclear fusion, the process that powers the Sun.

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.

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.
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.
Millions of people in the Horn of Africa lack safe, reliable and affordable water throughout the year.
