Electricity trial to pay users to cut power during high demand or natural disasters

Guardian Environment News - Thu, 2017/05/18 - 8:08pm

Arena and Aemo to trial program that would pay South Australian and Victorian customers to reduce their use

South Australian and Victorian electricity users will be paid to voluntarily forego power use during times of extreme stress on the power grid under a trial program announced by national energy regulators.

The Australian Renewable Energy Agency (Arena) and the Australian Energy Market Operator (Aemo) are looking to trial the program next summer, following outages earlier this year in South Australia and New South Wales caused by “an unprecedented level of demand”.

How Australia can use hydrogen to export its solar power around the world

Guardian Environment News - Thu, 2017/05/18 - 4:42pm

Recent innovations in hydrogen generation, storage, transport and use could transform it into the ultimate source of clean energy

Nearly a century ago, British scientist JB Haldane saw an energy future in which wind power would be used to generate hydrogen; a fuel he described as, weight-for-weight, the most efficient known method of storing energy.

He thought this future was four hundred years away, but the so-called “hydrogen economy” may arrive a lot sooner thanks to a recent burst of innovations in hydrogen generation, storage, transport and use. And it could open a new energy export market for Australia.

Tree clearing may have killed 180 koalas in Queensland in two years, says wildlife group

Guardian Environment News - Thu, 2017/05/18 - 1:25pm

World Wildlife Fund calls for public pressure on the Palaszczuk government to reduce habitat destruction

Tree clearing may have killed as many as 180 koalas in south-east Queensland in the two years after the former state government relaxed vegetation protection laws, according to an analysis by the World Wildlife Fund.

The environmental group says a crisis gripping koala populations has its root in a surge in tree clearing given the political green light in both Queensland and New South Wales.

Predators that attacked the clay caterpillars left telltale bite marks, which were later analyzed to help figure the critter's risk of getting eaten. That analysis revealed a striking pattern.

Brown hares and hunting | Water in Bagno Vignoni | 35mm film canisters | Letter from the Tories | Granny Seaside and Granny Cat

A repeal of the 2004 Hunting Act would accelerate the demise of our iconic brown hares, already listed in 2011 for potential extinction by 2050 (May pledges free vote on hunting, 10 May). One third of the hunts (with dogs) in England and Wales target these declining hares, not foxes. The act outlaws hare coursing, but a repeal would further encourage this intrusive and destructive activity, already so distressing to farmers and problematic to police forces countrywide.

Climate change is turning Antarctica green, say researchers

Guardian Environment News - Thu, 2017/05/18 - 9:00am

In the past 50 years the quantity and rate of plant growth has shot up, says study, suggesting further warming could lead to rapid ecosystem changes

Antarctica may conjure up an image of a pristine white landscape, but researchers say climate change is turning the continent green.

Scientists studying banks of moss in Antarctica have found that the quantity of moss, and the rate of plant growth, has shot up in the past 50 years, suggesting the continent may have a verdant future.

Sea level rise will double coastal flood risk worldwide

Guardian Environment News - Thu, 2017/05/18 - 7:10am

Small but unstoppable increases will double frequency of extreme water levels with dire consequences, say scientists

Small but inevitable rises in sea level will double the frequency of severe coastal flooding in most of the world with dire consequences for major cities that sit on coastlines, according to scientists.

The research takes in to account the large waves and storm surges that can tip gradually rising sea levels over the edge of coastal defences. Lower latitudes will be first affected, in a great swath through the tropics from Africa to South America and throughout south-east Asia, with Europe’s Atlantic coast and the west coast of the US not far behind.

Product designers 'must reduce Pringles factor' to boost recycling

Guardian Environment News - Thu, 2017/05/18 - 2:17am

Recycling Association chief cites crisp brand as one of worst examples of multiple materials being used in single product

Product designers need to retreat from “the Pringles factor” in order to make their packaging more recyclable, an environmental expert has said.

Simon Ellin, the chief executive of the Recycling Association, which represents recyclers, pointed to the snack tube as a prime example of the failure to consider recycling in design – and listed a range of other offenders from Lucozade Sport drinks to whisky packaging.

Less than 1% of surplus food from farms and manufacturers used to feed hungry

Guardian Environment News - Wed, 2017/05/17 - 10:31pm

A tiny proportion of excess food is being sent to charities and is instead ending up in landfill or left to rot, figures show

Less than 1% of edible surplus food produced by UK manufacturers and farms is being sent to charities to help feed the hungry, according to new figures.

Vegetables that are perfectly edible are being left to rot in the fields, and other foods not sold to retailers are put into anaerobic digestion or sent straight to landfill, the UK’s largest redistribution charity FareShare has warned.

Middlehope Moor, Weardale Miners who left waste rock beside the burn created a perfect habitat for the spring sandwort

On a grey day in a tree-less landscape, buffeted by a bone-chilling north-easterly wind, only the calls of curlews and oystercatchers that had returned here to breed suggested this must be spring.

But when we reached the stony, undulating, ground near the entrance to the “governor and company’s level”, a mine tunnel driven into a hillside almost two centuries ago by the London Lead Company, we found an infallible floral indicator of the season.

Offshore oil and gas regulator says there was a 10,500-litre spill in April 2016 but refuses to reveal where it occurred or company responsible

An offshore oil and gas well in Australia leaked oil continuously into the ocean for two months in 2016, releasing an estimated 10,500 litres. But the spill was never made public by the regulator and details about the well, its whereabouts and operator remain secret.

In its annual offshore performance report released this week, the National Offshore Petroleum Safety and Environmental Management Authority included a mention of a 10,500-litre spill in April 2016. It provided limited details about, noting that it had been identified during a routine inspection.

Australia's 2018 gas shortage will not eventuate, report shows

Guardian Environment News - Wed, 2017/05/17 - 1:11pm

Predicted shortfall no longer on horizon – and opening up new coal seam gas fields will not bring down prices, researchers say

A predicted shortage of gas for electricity generation in Australia from 2018 will not eventuate, and the recent surge in domestic prices will not be mitigated by opening up new coal seam gas fields, according to a new report.

In March, the Australian Energy Market Operator (Aemo) predicted that without national reform, Australia would face gas shortages, which would drive power outages, in 2018 and 2019.

WHO figures show people in Britain are more likely to die from dirty air than those living in some other comparable countries

People in the UK are 64 times as likely to die of air pollution as those in Sweden and twice as likely as those in the US, figures from the World Health Organisation reveal.

Britain, which has a mortality rate for air pollution of 25.7 for every 100,000 people, was also beaten by Brazil and Mexico – and it trailed far behind Sweden, the cleanest nation in the EU, with a rate of 0.4.
