#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.

It's on track to outrun bitcoin mining by the end of the year. That's a lot of energy to waste on what is essentially a bullshit generator.

Headline: #AI Is Eating Data Center Power Demand—and It’s Only Getting Worse

Subtitle: A new analysis of AI hardware being produced and how it is being used attempts to estimate the vast amount of #electricity being consumed by AI.

"There is the question of whether a U.S. secretary of transportation who is a former Fox Business television host is going to be able bring transformational change to the U.S. air transport system...[and] The air traffic control system is not the only infrastructure system at risk. The American electrical grid may be subject to “‘elevated’ risk of blackouts this summer.”

“Nuclear-friendly France is, according to Spain and Portugal at least, delaying new links to prevent cheap solar and wind energy from flooding the French market.

French grid operator RTE denies this. Both a cable via the Bay of Biscay and an overland powerline should address the shortage.”

Kenya’s latest energy policy review shows that electricity access rose from 37% in 2013 to 79% in 2023. Almost everybody living in an informal urban settlement now has access to an electricity connection, raising the overall urban access rate to nearly 100%. The Kenyan government is aiming to reach 100% electricity access by 2030 and 100% renewable electricity generation by 2035.

ForbesKenya More Than Doubled Electricity Access Over A DecadeElectricity access soared from 37% in 2013 to 79% in 2023, and Kenya is reaching toward fully renewable electricity in the next decade. But significant gaps remain.

#TasNetworks not equipped to handle 2024 #storm event & #outages, review finds.

In August last year, #Tasmania was hit by a #severe #weathersystem that lasted for five days.

It pummelled the state with heavy rain, #flooding & damaging winds that caused #extensivedamage to the #electricity #distributionnetwork.

All in all, 47,000 customers were left without power in the middle of winter, some for a week or more. #auspol

The #AI Boom Is Draining #Water From the Areas That Need It Most
A Bloomberg News analysis finds that roughly two thirds of new #datacenters built or in development in the #US since 2022 are in places with high levels of water stress.
The data centers that power #artificialintelligence consume immense amounts of water to cool hot #servers and, indirectly, from the #electricity needed to run these facilities.

The Tanzanian government has set an ambitious goal of universal electricity access by 2030, and its progress, from a mere 14% national coverage in 2011 to 46% in 2022, is one of the fastest expansion rates in Sub-Saharan Africa.

A key driver has been its rural electrification program, which has connected nearly eight million people, over 1,600 healthcare facilities, about 6,500 educational institutions, and more than 16,000 businesses to the grid. #Africa #tanzania #electricity

World BankLet There be Light: In Tanzania, More Electricity Brings Better Education and HealthThe World Bank is supporting the expansion of energy access through initiatives like the Tanzania Rural Electrification Expansion Program.

Researchers in Alberta are developing saltwater batteries.
"“With current options for energy storage like lithium batteries being too expensive for long-duration storage, Aqua-Cell Energy is everything lithium is not,” he says. “Our flow battery pumps saltwater through a battery stack where electricity is applied to store energy in the saltwater.”

He shares that when this process is run in reverse, it generates usable electricity.

“Our technology is the world’s most environmentally friendly #battery storage option … and using low-cost saltwater as the electrolyte allows for affordable long duration energy storage of upwards of 12 hours.” "

If the world covered every suitable #roof with #solar panels, it could supply 2/3 of humanity’s total #electricity consumption – allowing the globe to transition completely off of #fossifuell electricity generation, according to a new study out of the University of Sussex.
It found that rooftop solar could provide a total of 19,483TWh of electricity, which is about 2/3 of global electricity use (which was 29,664TWh in 2023).
