The fifth and final floating wind turbine has been secured off the coast of Scotland in a trial that will power 20,000 homes. The Hywind project is the result of more than 15 years of work from Norwegian energy firm Statoil. It's yet another clean energy technology being shown off at a time when Australia signals a move away from previous clean energy goals.

The Nintendo Switch is a tiny console with tiny controllers all powered by tiny batteries with tiny capacities. Charging is just part of life with the Switch, which is why it's spawned hundreds of power accessories, including this portable battery that looks like the most boring Switch game you can play.
Video: Unlike a battery, which stores power as chemical energy that's slowly and steadily discharged to keep your gadgets running, a capacitor can unload all of its juice in the blink of an eye. Even a small capacitor has the potential to stop your heart, but when it's the size of a dishwasher, well, this watermelon demonstrates exactly how destructive it can be.
Free-roaming wireless power has been a dream of engineers since the days of Tesla and Edison waging their war of innovation, but a number of technical hurdles have prevented it from becoming a reality. The folks at Disney Research have revealed that they have successfully built a method to provide full coverage of an average room and power all the devices one might need.
The promise of USB-C is great: One cable to connect all of your devices, laptops, tablets and smartphones. Unfortunately it comes with the big caveat that you might end up damaging your gear if you cheap out on a USB-C cable. But Satechi's new Type-C Power Meter makes it easy to tell if your USB-C gadgets are at risk of getting fried, or under-powered, by a sketchy accessory.
There are all kinds of reasons you might want to minimise the power draw of your laptop or desktop. To save battery, of course, but also to keep your electricity bills lower and reduce your impact on the planet. Here are all the ways you can knock down the amount of power your computer is drawing.
A meterologist, a climate science professor and the Deputy Director of the Monash Energy Materials and Systems Institute gave us their insights on the recent "unusual" tropical weather patterns appearing in South Australia, what exactly is causing the continual blackouts, and how renewables can help.
There's no point in buying a backup battery if you keep forgetting to top off your mobile devices before they die. So Griffin Technology's new PowerBlock Beacon and PowerJolt Beacon external chargers will actually send your smartphone or tablet a notification when they're nearby, reminding you to top off their batteries.
The Senate inquiry’s report into the planned closure of coal-fired power stations will no doubt shed light on the compelling health reasons to close them.
Coal-fired stations are a health hazard to their local communities and beyond due to the pollutants they emit. The resulting illnesses are a significant cost to health budgets. Climate change caused by burning fossil fuels brings its own health burdens.
Researchers at Ghent University have hit on a method of harvesting energy from raw sewage that treats the wastewater without using external electricity. It's all thanks to starving bacteria. Although this method is still in its lab testing stage, industry leaders are already interested in utilising it.
It took "one of the most significant severe thunderstorm outbreaks in recent decades", with seven tornadoes and a storm producing phenomenally damaging wind speeds, to bring down South Australia's power grid and cause a blackout in late September. Although the national electricity market operator and conservative commentators were quick to blame renewable energy, it's now clear that the entire network was at risk -- and the blackout could have been lessened had precautionary steps been taken.
Yesterday evening, South Australia suffered through a massive state-wide blackout. If you were caught in it, you might have been caught unawares -- without a light source, batteries, and a way of keeping your phone charged. Here are five things you can do to make sure you and your property are ready for the next blackout that happens.
