Emissions from fossil fuel production of the potent greenhouse gas methane is up to 40 per cent higher than previously understood, say researchers, shining a harsh spotlight on the global gas industry.

There's a new power bank on the market that promises to keep your smartphone charged without the need for a traditional power outlet. Instead, it receives its juice from the sun. But does it actually work as advertised? We put one through its paces to find out.
Last year, I called a company about installing solar panels at my house. I was told they wouldn't do the installation because of the shade cast my neighbour's massive tree. I was extra surprised when the sales guy told me he was looking at a satellite image that was just a couple of days old. Now I know how he got the information.
Have you ever used a public charging station to charge your mobile phone when it runs out of battery? If so, watch out for "juice jacking". Cybercriminals are on the prowl to infect your mobile devices such as smartphones and tablet computers and access your personal data, or install malware while you charge them.
Australia's catastrophic bushfires have left thousands of Aussies across New South Wales and Victoria without power, a situation that could last several weeks. Additionally, damage to the Snowy Hydro's power transmission lines has reduced the stability of the East Coast's power supply. To help out, the government is urging all Australians to reduce their energy use - which will have the added benefit of lowering your power bill. Here's some simple ways you can help.
One of the major problems with home solar panels is their size and appearance - who wants to bung a bunch of huge, ugly oblongs all over their roof? Now, imagine if the same solar cells could be built directly into the very fabric of your house. You just imagined something called "building-integrated photovoltaics" - and the technology exists right now.
Atlassian founder Mike Cannon-Brookes is teaming up with Tesla and 5B to help install solar panels and batteries in towns cut off from power after the devastating bushfires. It comes after the software billionaire donated $12 million to the cause in a hope to speed up recovery efforts in the region.
