"Using some mapping we found that the rooftops of 14 of Auckland's largest buildings would have the same land area as the largest solar farm under construction [in Aotearoa]. So we could potentially be distributing those solar panels in our city ..."

#ClimateChange and #energy

We did the math on #AI’s energy footprint. Here’s the story you haven’t heard.
The #emissions from individual AI text, image, and video queries seem small—until you add up what the industry isn’t tracking and consider where it’s heading next.
The latest reports show that 4.4% of all the energy in the #US now goes toward #datacenters. The #carbon intensity of #electricity used by data centers was 48% higher than the US average.

Humanity needs to stop wasting public money on nuclear investment, and invest it in renewables. Especially decarbonizing proven renewable tech. Figuring out how to build and maintain renewable generation without energy and byproducts (plastics, etc) from fossil fuels is an important area of experimentation in itself.

And in #GoodNews ...

"Scientists have used solar power to heat an object to 1,800 degrees Fahrenheit (1,000 degrees Celsius) — hot enough to power a steel furnace. The proof-of-concept study, published May 15 in the journal Device, demonstrates how solar energy could replace fossil fuels in high-temperature manufacturing processes, such as smelting steel."

China's going to be fine.

"In China, people burned crude oil and gas for heat and light as early as 500 B.C. By the fourth century A.D., they were drilling for these natural resources and transporting it via bamboo pipes."
