GE: Industrial giant will stop building coal-fired power plants

US industrial giant General Electric said it would shut or sell sites as it prioritised its renewable energy and power generation businesses. It comes ahead of a US Presidential election in which the candidates hold starkly different views on coal. NGO the Natural Resources Defense Council said the move was "about time". GE has said in the past it would focus less on fossil fuels, reflecting the growing acceptance of cleaner energy sources in US power grids. But just five years ago, it struck its biggest ever deal - paying almost £10bn for a business that produced coal-fuelled turbines.

In a statement, the firm suggested the decision had been motivated by economics. Could the coronavirus crisis finally finish off coal? Climate change: Earthquake 'hack' reveals scale of ocean warming. Image copyright Getty Images Scientists have found a clever new way of measuring ocean warming, using sound waves from undersea earthquakes.

Climate change: Earthquake 'hack' reveals scale of ocean warming

The researchers say the "hack" works because sound travels faster in warmer water. The team looked at sonic data from the Indian Ocean emitted by tremors over a 10-year period. Plug-in hybrids are a 'wolf in sheep's clothing' Image copyright Getty Images Carbon dioxide emissions from plug-in hybrid cars are as much as two-and-a-half times higher than official tests suggest, according to new research.

Plug-in hybrids are a 'wolf in sheep's clothing'

Plug-in hybrid vehicles are powered by an electric motor using a battery that is recharged by being plugged in or via an on-board petrol or diesel engine. They account for 3% of new car sales. But analysis from pressure groups Transport and Environment and Greenpeace suggest they emit an average of 120g of CO2 per km. Google says its carbon footprint is now zero.

Google says its carbon footprint is now zero

It became carbon-neutral in 2007 and says it has now compensated for all of the carbon it has ever created. Other large technology companies have also committed to reducing or eliminating their carbon use. Mr Pichai said Google's pledge to be using only carbon-free energy by 2030 was its "biggest sustainability moonshot yet". "We'll do things like pairing wind and solar power sources together and increasing our use of battery storage," he said.

Pringles tube tries to wake from 'recycling nightmare'

The current container for the potato-based snack was condemned as a recycler’s nightmare. It's a complex construction with a metal base, plastic cap, metal tear-off lid, and foil-lined cardboard sleeve. The Recycling Association dubbed it the number one recycling villain – along with the Lucozade Sports bottle.

Dounreay, near Thurso, was the UK site for the development of fast reactor research from 1955 to 1994. The facility on the north Caithness coast is in the process of being closed down, demolished and cleaned up. However, the Nuclear Decommissioning Authority said it would be 2333 before the 148-acre site is safe for reuse. 'Highest temperature on Earth' as Death Valley, US hits 54.4C.

Nestlé sued over tonnes of dead fish in French river

Several tonnes of dead fish were reported in the Aisne river at the weekend, close to a Nestlé factory. The deaths were due to a decrease in oxygen levels in the water, the local prefecture said on Tuesday. Tests are being carried out to determine the origin of the pollution. The dead fish were found near Challerange, 50km (31 miles) from Reims, the prefecture said in a statement. "We have lodged a complaint against Nestlé France for pollution and violation of article 432.2 of the environmental code," said Michel Adam, president of the Ardennes Fishing Federation. The damage amounts to "several thousand euros", he added. Will tech make it easier for us to grow veg? Davos: The compostable bags trying to replace plastic.

Davos: The compostable bags trying to replace plastic

Cleantechnica. January 5th, 2020 by Steve Hanley Many of us have tunnel vision on the subject of energy storage. We think lithium-ion batteries are the beginning, middle, and end of the discussion. Largely that’s because of Elon Musk and Tesla, who have built their incredible history of success both in transportation and energy storage on lithium-ion batteries. Yet there are other types of storage solutions, many of which will begin to share the spotlight with lithium-ion batteries in 2020. The US Department of Energy’s Advanced Research Projects Agency — ARPA-E — is funding research by 10 organizations with one common goal — creating long term energy storage systems that cost $0.05 per kilowatt hour or less.

Jakarta floods: Cloud seeding used to try to stop rain. Image copyright Reuters Indonesian authorities are turning to the technique of cloud seeding to try to stop more rain falling in the flood-hit capital Jakarta. Planes have been sent to inject chemicals into clouds in an effort to alter precipitation. Jakarta and surrounding districts have struggled to cope since a storm on New Year's Eve left large areas underwater. At least 43 people are known to have died, with some 192,000 evacuated, and more rain is expected. According to Reuters news agency, two planes have been sent up to shoot salt flares into the clouds, which will hopefully make them break before they reach the Jakarta region. "All clouds moving towards the Greater Jakarta area, which are estimated to lead to precipitation there, will be shot with NaCl (sodium chloride) material," Indonesia's technology agency BPPT explained in a statement.

Temperatures in southern California had soared to 20 degrees above normal, prompting the National Weather Service to issue warnings for extreme fire danger and heat-related illnesses. The weather was a fitting introduction to what I had come to see inside Nate’s lab—how we might be able to tap the sun’s tremendous energy to make fuels to power cars, trucks, ships, and airplanes. Stepping into the lab cluttered with computer screens, jars of chemicals, beakers, and other equipment, Nate handed me a pair of safety goggles and offered some advice for what I was about to see.

“Everything we do is simple in the end, even though there’s lots of complicated stuff,” he said.

The World Health Organisation (WHO) says air pollution causes the death of seven million people a year and accounts for a third of fatalities from stroke, lung cancer and heart disease, with more than 90% of children breathing toxic air every day.

Until we tackle the root causes of air pollution - burning fossil fuels mainly - we can at least learn where and when it is likely to be at its most dangerous.
