Supersized solar farms are sprouting around the world (and maybe in space, too)

Posted by in categories: solar power, space, sustainability

In a quest to cut the cost of clean electricity, power utilities around the world are supersizing their solar farms.

Nowhere is that more apparent than in southern Egypt, where what will be the world’s largest solar farm — a vast collection of more than 5 million photovoltaic panels — is now taking shape. When it’s completed next year, the $4 billion Benban solar park near Aswan will cover an area 10 times bigger than New York’s Central Park and generate up to 1.8 gigawatts of electricity.

Bank of England’s chief economist warns A.I. could threaten ‘large’ amount of jobs

Posted by in categories: economics, employment, finance, robotics/AI

“This is the dark side of technological revolutions and that dark side has always been there,” Haldane added. “That hollowing out is going to be potentially on a much greater scale in the future, when we have machines both thinking and doing — replacing both the cognitive and the technical skills of humans.”


Haldane said that the so-called Fourth Industrial Revolution — a digitally-driven paradigm shift similar to previous industrial revolutions in the West — had the potential to displace numerous jobs and leave people “technologically unemployed.”

“Each of those [industrial revolutions] had a wrenching and lengthy impact on the jobs market, on the lives and livelihoods of large swathes of society,” Haldane told the BBC.

Ecosystems are getting greener in the Arctic

Posted by in categories: climatology, sustainability

In recent decades, scientists have noted a surge in Arctic plant growth as a symptom of climate change. But without observations showing exactly when and where vegetation has bloomed as the world’s coldest areas warm, it’s difficult to predict how vegetation will respond to future warming. Now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have developed a new approach that may paint a more accurate picture of Arctic vegetation and our climate’s recent past – and future.

In a study published online Aug. 20 in Nature Climate Change, the researchers used satellite images taken over the past 30 years to track – down to a pixel representing approximately 25 square miles – the ebb and flow of in cold areas of the northern hemisphere, such as Alaska, the Arctic region of Canada, and the Tibetan Plateau.

The 30-year historic satellite data used in the study were collected by the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer. The data was processed by Boston University, and is hosted on NEX – the NASA Earth Exchange data archive.

Researchers are developing fast-charging solid-state batteries

Posted by in categories: climatology, materials

Solid-state batteries contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling, and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Juelich scientists have now introduced a new concept that allows currents up to 10 times greater during charging and discharging than previously described in the literature.

Low current is considered one of the biggest hurdles in the development of solid-state batteries because the batteries take a relatively long time to charge, usually about 10 to 12 hours in the case of a fully discharged . The new cell type that Jülich scientists have designed, however, takes less than an hour to recharge.

“With the concepts described to date, only very small charge and discharge currents were possible due to problems at the internal solid-state interfaces. This is where our concept based on a favourable combination of materials comes into play, and we have already patented it,” explains Dr. Hermann Tempel, group leader at the Juelich Institute for Energy and Climate Research (IEK-9).

New study identifies strategies in US climate litigation

Posted by in categories: climatology, health, policy, sustainability

The courts have played a central role in climate change policy, starting with a landmark Supreme Court case that led to the mandatory regulation of greenhouse gases in the United States. How do the courts address climate cases today? Who wins, who loses and what kinds of strategies make a difference in the courtroom?

Researchers at the George Washington University (GW) have published a study in Nature Climate Change that for the first time analyzes all U.S climate change lawsuits over a 26-year period.

“This first-of-a-kind study outlines the types of climate change lawsuits that are more likely to win or lose, and why,” said lead author Sabrina McCormick, Ph.D., MA, an Associate Professor of Environmental and Occupational Health at GW’s Milken Institute School of Public Health (Milken Institute SPH). “Efforts to affect U.S. should consider current trends in the courtroom.”
