ARENA to provide $10m to Chinese wind giant to build Australia's first hybrid wind-solar farm, although grant is nearly four times more than being asked by projects in large scale solar tender.

The Solar Impulse becomes the first aircraft to circle the globe powered by the sun after landing in Abu Dhabi on the last leg of its journey.

Solar Impulse 2, which landed in Abu Dhabi, is first plane powered by the renewable energy source to tour the globe

Solar Impulse 2 has completed the first round-the-world flight by a solar-powered aeroplane, after touching down in Abu Dhabi early on Tuesday.

The final leg of the feat, aimed at showcasing the potential of renewable energy, was a bumpy one, with turbulence driven by hot desert air leaving the solo pilot, Bertrand Piccard, fighting with the controls.

DISEASE TRIGGER?: Fire brought warmth and comfort to early humans but may also have triggered the emergence of deadly tuberculosis, Australian researchers suggest.

Switching from diesel to solar power has reduced power costs and given two remote Northern Territory communities a new lease on life

Deep in the outback, about a 90-minute drive from Tennant Creek, two tiny Indigenous communities in the Northern Territory are coming back to life.

Since May, the Kunapa communities of Ngurrara and Kurnturlpara have been returning to the Barkly tableland, moving into the houses that had been abandoned years ago, setting up a School of the Air for their 15 children, and re-establishing their Indigenous culture. In fact, in a little over a month, the population has increased from just two people to about 40. And the reason? Solar power.

Research found that 23% of violent clashes in ethnically divided places were connected to climate disasters

Climate-related disasters increase the risk of armed conflicts, according to research that shows a quarter of the violent struggles in ethnically divided countries were preceded by extreme weather.

The role of severe heatwaves, floods and storms in increasing the risk of wars has been controversial, particularly in relation to the long drought in Syria. But the new work reveals a strong link in places where the population is already fractured along ethnic lines.

Newly completed Coonooer Bridge wind farm achieves capacity factor of nearly 50 per cent in the first full three months since it began operations.

Britain’s front gardens are being paved for parking while back gardens become patios. But in Canada and the US, the Depave movement is tearing up hard surfaces

In towns and cities, flash floods are a growing problem. The concrete jungle can’t soak up rainwater, so in heavy downpours it has nowhere to go except into drains, overloading them and setting off flash floods.

A movement in Canada and the US called Depave is tearing up concrete and asphalt in local neighbourhoods and replacing it with gardens to soak up rainwater and help prevent flooding. And although Depave is largely unknown in Britain, there’s a growing need for similar action here.

Contrarian climate scientist Roy Spencer summed up the contrarian case for a fossil fuel and tobacco-funded think tank

When I give a presentation and mention the 97% expert consensus on human-caused global warming, I’m often asked, “what’s the deal with the other 3%?”. These are the publishing climate scientists who argue that something other than humans is responsible for the majority of global warming, although their explanations are often contradictory and don’t withstand scientific scrutiny.

A few months ago, the world’s largest private sector coal company went to court, made its best scientific case against the 97% expert consensus, and lost. One of coal’s expert witnesses was University of Alabama at Huntsville climate scientist Roy Spencer - a controversial figure who once compared those with whom he disagreed to Nazis, and has expressed his love for Fox News.
