With AI still the hot new trend, demand for compute to operate it is pushing the growth of bit barn capacity along with the need for ever more energy to power it all. This growth is having some unintended effects, at least in America.
In Omaha, one power company has had to abandon plans to stop burning coal to produce electricity because of the need to serve demand from nearby datacenters, according to [1]The Washington Post , picking out Google and Meta in particular.
[2]
It claims that rising energy demands from those facilities mean that two coal-burning generators at the North Omaha power plant cannot be decommissioned without risking a power shortage for that district.

This is despite previous undertakings from the operator, the Omaha Public Power District, that it would cease burning coal in order to improve air quality in the surrounding area, endangering public health as well as continuing to spew out greenhouse gas emissions.
In response, Google pointed us to an [5]announcement it made last month that it is working with the Omaha Public Power District on a procurement framework that will enable the search giant to supply the utility firm with carbon-free energy resources.

This isn't an isolated incident. The Register reported earlier this year that [7]coal-generated energy was being given a reprieve in the US thanks to the growing energy demands of datacenters, not helped by developers determined to throw as many high-performance servers packed with energy-guzzling GPUs as possible at training their generative AI models.
This growth has caught out many utility companies, which have until now faced flat or shrinking demand in the US market and planned their infrastructure investments accordingly. A [8]report published last week by management consultants Bain & Company warned that unless they adapted quickly to expand generation and supply capacity by up to 26 percent, energy use might outstrip supply within a couple of years.
It also warned that datacenter operators might seek alternative sources of power if utility companies don't move quickly enough, but this already seems to be happening, as can be seen from various reports of tech companies showing interest in nuclear power.

Oracle is one of the more recent examples, [10]disclosing during its latest earnings call that the company has secured building permits for a trio of small modular reactors (SMRs) to power a bit barn with over a gigawatt of AI compute capacity.
Earlier this year, Amazon Web Services (AWS) revealed that it had [11]taken possession of a datacenter campus owned by Talen Energy built next to its Susquehanna nuclear power plant in northeast Pennsylvania.

Last month, Microsoft announced a deal that will see the [16]Three Mile Island nuclear plant come back online, thanks to a 20-year power purchase agreement (PPA) with Constellation Energy, which owns the facility.
However, some of these projects are likely to be long-term, with one analyst [17]telling us a while back that the most optimistic time frame for deployment of technology such as SMRs in the United States is by 2030.
If cleaner sources of energy cannot be found, power companies will likely continue to rely on fossil fuels such as coal and gas to meet the growing demand from bit barns and other applications such as electric vehicles.
Financial services giant Morgan Stanley last month published its own [18]report on the datacenter industry , warning that global greenhouse emissions between now and the end of the decade are likely to be three times higher than if generative AI had not been developed. ®

Hmm
On the plus side it keeps actual energy production online. And its not like it can only run when the sun is shining and wind is blowing so it needs reliability
Re: Hmm
Because it's not like Google could only crawl new sites to index while the sun is up, or only recompress YouTube videos at other resolutions when the wind is blowing.
Cat videos are a strategic national resource and must be available at locally all at times. You expect people to wait an extra 50ms to be served an ad from 2 states away?

"Because it's not like Google could only crawl new sites to index while the sun is up, or only recompress YouTube videos at other resolutions when the wind is blowing."
Why should they? And if it takes weeks for the wind to blow it might become a bit of an issue.
"Cat videos are a strategic national resource and must be available at locally all at times."
You dont need your light to come on when you hit the light switch but lets see how long you go without before changing your mind. Hell some people get overwhelmed at their surroundings if their phone dies for christ sake.
But we are talking about the developed world. You would think we would be able to generate energy with our long history of doing so instead of falling back into the old problems of praying to whatever deity to provide the right weather.
Re: Hmm
Suggesting we might have a bit of a rethink about datacenters.
We are still in the banking/Telco mindset of 9-9a uptime with multiple redundancy to avoid any performance degradation at any cost.
But more of the load isn't as tie critical. If I train an AI for only 50% of the time when power is 10% of the price, or I buy 50% cheaper hw that needs a daily reboot I might come out ahead.
Maybe it will be cheaper to serve YouTube from different data centers?
Re: Maybe it will be cheaper to serve YouTube from different data centers?
It would be cheaper to not serve YouTube at all.
Or Facebook. Or twatter. Or TikTok. You get the idea.
The appropriate move would be to slap a carbon tax on it (along with crypto-mining). Instead of that, what happens? HMG of any colour will dive right into it and demand more.
