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.

Lego has invested $1.2 Billion over the last four years to balance 100 per cent of its energy use with that from renewable sources, and now that goal has been achieved - three years early.

To celebrate, Lego has set a Guiness World Record by building a seven and a half metre tall wind turbine out of 146,000 Lego bricks, because why not.

In a recent trial of 'mini grid' technology, a group of eight Melbourne houses were linked to each other to form a self-sustaining, all-renewable grid completely independent of mains electricity. Electricity was drawn instead from combined solar and battery systems on the houses, which could even cover the houses without solar systems installed.

The bacterial world is rife with unusual talents, among them a knack for producing electricity. In the wild, "electrogenic" bacteria generate current as part of their metabolism, and now researchers at the University of California, Santa Barbara (UCSB), have found a way to give that ability to non-electrogenic bacteria.

This researchers say this discovery could be used in sustainable electricity generation and wastewater treatment.
