A few years ago, Jacqueline Freidel and her husband built their new home near Madison, Wisconsin, complete with four bedrooms and an open-concept floor plan.
But the couple’s house has a hidden feature - it runs entirely on electricity and is net-zero, meaning it produces just as much energy as it uses every year.
Freidel: “If you were walking by and didn’t know anything about the house, you might not even guess that it is net-zero energy and all-electric.”
Freidel is an energy efficiency consultant. But she says anyone can build a net-zero ... Read more ...

| 'Leave politics to the politicians’: why rural Queensland is a hotbed of renewable energy - Guardian - Energy |
Apr 2 · Agriculture was once king in Glen Beasley’s neighbourhood on Queensland’s Darling Downs, a vast agricultural area about 200km west of Brisbane. “It was all grain, beef, timber and a bit of coal,” he says.
Then a high voltage power line was built through his family farm outside Chinchilla in 1984. The whispers of gas came with the turn of the millennium, and by the early 2010s, the coal seam gas industry was booming. Gas company Arrow Energy now holds a tenement over his property and a few doors down, there’s a coal seam gas waste facility.
“Now we have traffic lights in town, more shops, and there’s a lot more people around,” Glen’s wife, Barbara Beasley, says. “But when ... Read more ...

| A better way to predict Arctic riverbank erosion - PHYS.ORG - Earth |
Apr 25 · But there's a caveat to this concern: Existing models have predicted a more dramatic rate of Arctic riverbank erosion than has actually been observed. In a new study published in the Journal of Geophysical Research: Earth Surface, Madison Douglas and Michael Lamb set out to determine why.
To do this, the team created a model that couples the movement of sediment, such as sand and mud, with permafrost thaw to determine riverbank erosion. The model better reproduces erosion observations on parts of the Yukon River in Alaska. This is because in real-world scenarios, the rate of erosion is slowed by an insulating layer of thawed sediment. Rather than the warmer river water ... Read more ...

| A new electrochemical approach could reduce ocean acidity and remove carbon in the process - PHYS.ORG - Earth |
Apr 23 · Only 45 percent of carbon dioxide emissions remain in the atmosphere; the remainder is absorbed through two cycles: 1) the biological carbon cycle stores CO2 in plant matter and soils, and 2) the aqueous carbon cycle absorbs CO2 from the atmosphere into the oceans. Each of these cycles accounts for 25 percent and 30 percent of emitted CO2, respectively.
CO2 that dissolves in the oceans reacts to form chemicals that increase the acidity of the oceans. The dissolution of minerals from rocks along coastlines act to counterbalance this acidity, in a process called geological weathering, but the extreme increase in the rate and volume of CO2 emissions, especially over the last 60 ...

| Large methane mitigation potential through prioritized closure of gas-rich coal mines - Nature Climate Change |
Apr 25 · Large-scale closure of coal mines is required for China to achieve carbon neutrality. However, what this means for methane emissions, particularly for abandoned mine methane (AMM), is highly uncertain. Here we construct a detailed and dynamic coal mine database to estimate China’s coal methane emissions during 2011–2019 and evaluate future emission trajectories based on different mine closure policies. We find that AMM emissions have been largely underestimated, which leads to an increased proportion of AMM in China’s total coal methane emissions, and are expected to become the dominant source by 2035. We develop a coal mine closure strategy prioritizing high-gas-content mines. ... Read more ...

Apr 25 · In their paper published in the journal Science, the group describes how experiments they conducted led to the discovery of a way to get some fluids such as water and oil, to remain as an emulsion for long periods of time without the use of surfactants.
It is widely known that when two immiscible liquids, such as water and oil are mixed, they do not remain so for very long—they slowly separate into two layers. This is because they never really mix to begin with; instead, they coexist as droplets that coalesce when they come into contact with one another.
Because of this, chemists have developed various surfactants that force such liquids to remain "mixed" for some ... Read more ...
