[GWSG] Compressed air; change or else; UK cutting farmland; Danes luring diners; changes with the PHD

[Tilley, Al]

1. Canada’s Hydrostor has secured a $1.76 billion loan from the US Department of Energy to build a compressed air storage system in California. Willow Rock will supply 500 MW and 4,000 MW hours of long-duration energy storage to the southern CA power grid. Two problems have rendered such systems inefficient in the past: the loss of heat energy in the compression process, and a drop in air pressure in the storage cavity as power is produced. Hydrostor captures and uses the heat, and provides constant pressure in the underground storage space through injection of water from an above-ground tank. “An estimated 80% of US geology could support similar systems.” The system is an attractive alternative to standard batteries. https://electrek.co/2025/01/10/long-duration-compressed-air-energy-storage-project-just-got-a-1-76b-doe-loan/
2. A new study: "The future of humanity and all life on our planet depends on sustainability, and the data indicate that we will not succeed on the issue of climate change unless we change the way that we produce and consume food." https://phys.org/news/2025-01-based-diet-mitigate-climate.html
3. England is planning to reduce its farmland more than 10% by 2050. One effect will be to produce less meat, thus reducing emissions. https://www.theguardian.com/environment/2025/jan/31/farmland-in-england-to-be-reduced-by-more-than-10-under-government-plans
The English government appears to be approaching regulation of meat consumption indirectly; 10% seems to be too timid to be the final target or sole regulatory strategy.
4. Denmark produces more meat per capita than anyone else. Their government is joining with the Vegetarian Society to promote a transition to a plant-centered diet without attempts to force the issue—an approach more carrot than stick centered. https://www.theguardian.com/environment/2025/jan/31/more-carrot-less-stick-how-meat-loving-danes-were-sold-a-plant-led-world-first
5. This may be the time for you to consider trying the Planetary health Diet. If you already have, you may be ready to introduce others to the pleasures of the PHD. A new study published in Nature Sustainability explores what changes in our management of agricultural and water resources would follow global adoption of the diet. We could reduce cropland by 37-40% and lower use of irrigation water by 78% while managing global heating and becoming healthier. The changes would be a major part of building a sustainable way of living with the earth.   https://phys.org/news/2025-01-global-diet-environmental-impact.html
