The Australian government has given the green light to the first stages of what it describes as the country’s “biggest renewable energy project ever” – an ambitious proposal to send energy from a solar farm in the Northern Territory outback to Singapore via subsea cables.

The environment minister, Tanya Plibersek, said the approval under conservation law of SunCable’s $30bn-plus Australia-Asia Power Link was a “massive step towards making Australia a renewable energy superpower” and that the project would be “economically and socially transformational” for the NT.

England’s controversial eradication scheme may have caused higher rates of disease in surrounding areas, research shows

Researchers at the University of Oxford found that although badger culling reduced incidences of tuberculosis in the areas where it took place, in neighbouring areas the risk of the disease in cattle increased by almost a third.

John Boland and Chris Bryant use their garden to shade their house from Australia’s hot summers – and it helps feed them as well

As soon as John Boland moved into his house in inner-city Adelaide he got rid of the concrete and sheds and planted fruit trees. In the thirty years since, those trees have provided him with a third of his food and cooled his home so well that he doesn’t need air conditioning.

Deciduous trees on the western side of the house bathe the house in shade in the hot South Australian summer while letting in afternoon sun during winter. They also block hot breezes in summer and cold winds in winter.
