Community energy groups are coming up with renewable energy schemes. Shouldn’t government extend a hand to help them?

Yackandandah, like most Australian towns, has had its ups and its downs. One of its biggest ups was the north-east Victorian gold rush. By the 1890s our town was full of miners toiling to extract what was left of its alluvial gold. The only thing holding these folks back was an energy crisis. The miners were unable to source the power needed to sluice and dredge or crush the ore. The solution was a water race from high up on the West Kiewa river, which wasn’t the brainchild of government, or even the mines department – but rather a local man.

John Wallace, a Yackandandah resident, recognised a problem that needed immediate action and set about solving it.

Airport will ban arrivals and departures before 5.30am, and support the launch of an independent noise authority

Heathrow has agreed to curb night flights if permission is granted for a third runway, as it announced measures it claimed met all the conditions set by the Airports Commission for its expansion plan.

As well as banning all arrivals and departures before 5.30am, the airport said it would support the introduction of an independent noise authority, and pledged not to add new capacity unless it can do so without delaying UK compliance with EU air quality limits.

Filed patents show the British engineering firm may use solid-state batteries that could stretch electric car’s range to hundreds of miles and increase safety

Dyson could become the next Tesla motors as it develops a new electric car, according to a leading industry expert. Filed patents show the Dyson vehicle may use solid-state batteries, which would see the car’s range stretch to hundreds of miles and also be safer than current batteries.

In March, a government document revealed funding to help Dyson develop “a new battery electric vehicle”. The company declined to comment but in 2015 it said it planned to invest £1bn in battery technology and in October it bought solid-state battery company, Sakti3, for $90m, which founder Sir James Dyson said had “developed a breakthrough in battery technology”.

Interactive map commissioned by Lock the Gate shows fossil fuel claims cover 37% of Australia’s landmass

More than a third of Australia’s landmass is earmarked for coal or gas, according to a new analysis and interactive map commissioned by the community group Lock the Gate.

No single register of fossil fuel exploration and extraction licences and applications exists so, commissioned by Lock the Gate, Energy Resources Insights gathered spatial information on land earmarked for fossil fuels from state and federal regulators.

• Headlines ‘exaggerated’ climate link to sinking of Pacific islands

Five tiny Pacific islands have disappeared due to rising seas and erosion, a discovery thought to be the first scientific confirmation of the impact of climate change on coastlines in the Pacific, according to Australian researchers.

Air pollution kills 28,000 people every year in the UK. But the solution might lie in a hi-tech tower that sucks up harmful particles

High in the skies over London, the UK’s first air pollution monitoring squad have been using the latest sensors to chart the levels of ozone and nitrogen dioxide in our atmosphere. The team is highly trained, each equipped with a hi-tech backpack, and proficient in social media. Which all sounds relatively standard, apart from the fact that it is entirely made up of pigeons.

Using one of the UK’s best-known feathered friends as a publicity stunt for air pollution awareness was the brainchild of Plume Labs, which has created an app for monitoring pollution on the go. It follows on the heels of similar apps released in the past two years, ranging from UCLA’s AirForU to BreezoMeter, the brainchild of Israeli engineer Ran Korber, who was looking to buy a house for his family far away from polluted environments.
