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.

South Australia's always been on the front foot when it comes to renewable energyeven Tesla's given it the thumbs-up. On Friday, the state government revealed its "Hydrogen Roadmap", which "sets out clear pathways to capitalise on South Australia’s competitive advantages" and will "accelerate the State’s transition to a clean, safe and sustainable producer, consumer and exporter of hydrogen".

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?

Beginning in Melbourne's Federation Square today and tomorrow (August 14 and 15), there's a tiny Tesla house making the rounds of the country - showing off the Powerwall and educating the public on how to generate, store and use renewable energy for your home.

Oh, and the tiny home is towed by a Tesla Model X, because of course it is.

Solar has become the world’s favourite new type of electricity generation, according to global data showing that more solar photovoltaic (PV) capacity is being installed than any other generation technology.

Worldwide, some 73 gigawatts of net new solar PV capacity was installed in 2016. Wind energy came in second place (55GW), with coal relegated to third (52GW), followed by gas (37GW) and hydro (28GW).

Home batteries have never seemed like a smarter or more viable choice for households with solar since the Tesla Powerwall burst onto the scene less than two years ago. Soon after it wasn't just Tesla — other options were popping up on the market, a vast variety of batteries for different types of homes with different needs. We set out to speak to three early adopters of battery technology to see what it's like to live with solar batteries, to measure how its changed their energy use and — most importantly — their power bills.

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.

Indian multinational conglomerate Adani has given the go-ahead for work to start on its huge, controversial Carmichael mine in Queensland's Galilee Basin. While the move is being called out as a stunt — with many questioning where the funding for the project is coming from — it still beggars belief that the project has got this far at a time when our focus should be on investing in renewables and keeping our mineral resources in the ground.

Manufacturing 2,000 litres of drinkable water, extracted from the air (using renewable energy), at a cost of less than two cents per litre.

That's the challenge set to those entering the Water Abundance XPRIZE, where 98 teams from 25 countries will compete for the $1.75 million. Four Australian teams will take on the challenge, and we spoke to Hydro Harvest Operation (H20) about how they plan to win.

The southern stretches of the Monaro Highway make for a wholesome pastoral drive, passing fields full of cows and golden grass swaying in soft breezes. The road winds around hills and dams, at one point tipping up and over a crest to reveal an unexpected sight: thousands of solar panels shining in the hard Australian sun.

This is the Royalla Solar Farm — a paddock full of solar photovoltaic modules that together are capable of powering 4500 Canberra homes. And despite living in Australia's smallest territory, Royalla is just the tip of the iceberg when it comes to the ACT's solar accomplishments.
