6,500 home battery systems were installed across Australia in 2016. In the first half of 2017 alone that number has jumped to 7,000 - with analysts predicting at least 20,000 battery installations by the end of the year.

The cost of battery system installations has dropped - mainly due to increased competition among wholesalers - but only by five per cent. So what is causing the sudden and significant uptake? The rising cost of electricity, apparently.

New research shows 139 countries could be entirely powered by wind, water, and the sun by 2050.

This would mean around 24 million long-term jobs, a decrease between four and seven million air pollution-related deaths, a stable energy price, and a likely saving of over US$20 trillion in health and climate costs.

But how?

With the price of energy from new wind or solar rapidly dropping below that of traditional fossil fuels, renewable energy seems like a clear way forward. Yet despite massive strides in efficiency and affordability, the nature of renewable resources means you can't generate solar while the sun isn't shining, or wind while the wind isn't blowing. What you can do, however, is store that energy while conditions are good, and save it for a rainy day.

While there are now more solar panels in Australia than people, the many Australians who live in apartments have largely been locked out of this solar revolution by a minefield of red tape and potentially uninformed strata committees.

In the face of these challenges, Stucco, a small co-operative housing block in Sydney, embarked on a mission to take back the power. Hopefully their experiences can serve as a guide to how other apartment-dwellers can more readily go solar.

In sunny Australia, household rooftop solar can be a great way to generate some of your own power, and potentially save money off your electrical bill. Thanks to recent technology improvements and price reductions, home battery storage makes it possible to store the sun’s energy and use it again at night. But as more and more players enter the market, which option is right for you?

There's an abundance of amazing home smart tech hitting the market. From Samsung's Family Hub 2.0 fridge to the Amazon Alexa and Google Home (hopefully) finally hitting our shores. But there's more to the smart home than gadgets.

Let's take a look at how home automation and new tech like Tesla battery storage, smart thermostats, grid credits and smart meters are revolutionising our power consumption. Which also has a positive impact on both the environment and our bank accounts.

A new type of electrode developed by researchers at RMIT University has the potential to not only boost the capacity of existing energy storage technologies by 3000 per cent, but it opens the door to the development of flexible, thin film, all-in-one solar capture and storage. We're talking the means to self-powering smart phones, laptops, cars and buildings.

And it has all been inspired by a plant.

The island of Ta'u in American Samoa is home to around 600 people. Located in the southern Pacific Ocean, the island relied until recently on diesel generators for energy production — which meant that not only did the generators produce pollution as a byproduct, but the diesel itself had to be shipped in at a rate of around 300 gallons per day. SolarCity, a company just acquired by Tesla, took a year to set up the island with a bank of solar panels and Tesla Powerpack industrial-grade battery energy storage that means Ta'u now runs almost entirely off the sun.

Scientists at The Australian National University (ANU) have set a world record for efficiency for a solar thermal dish generating steam that could be used for power stations.

The team designed and built a new receiver for the solar concentrator dish at ANU, halving losses and achieving a 97 per cent conversion of sunlight into steam. The breakthrough could lead to the generation of cheaper base-load electricity from renewable energy and help lower carbon emissions which cause global warming.
