“I want to offer up a point for reasonable debate here: Suppose you are against new data center construction as a (clumsy) policy lever to regulate the pace of AI progress and harms.Do the facts matter? If the water issue is “fake” or overblown, but it’s resonating with voters…”
“AI often feels weightless: type a prompt, receive an answer, and move on. But behind every request are physical data centers, cooling systems, substations, transmission lines, servers and water networks. A recent UN University analysis estimates that global data centers used…”
“AI data centers need electricity, which can be from renewable sources and non-renewable sources, and the exact mix can change from day to day as well as long after these data centers are constructed. The electricity grid is decarbonizing at the fastest pace yet. It's simply a…”
Energy experts highlight the growing strain on local energy grids due to the rapid expansion of AI data centers, which drive demand for fossil gas and new power plants. This raises questions about sustainability and infrastructure capacity.

“AI data centers need electricity, which can be from renewable sources and non-renewable sources, and the exact mix can change from day to day as well as long after these data centers are constructed. The electricity grid is decarbonizing at the fastest pace yet. It's simply a tenuous link. On the other hand there are clear non-renewable fossil fuel being used in our daily lives that desperately need to be electrified, think non-electric vehicles and commercial flights. Even without considering m”
“A few things from the last month: A single downed power line near DC caused data centers to drop over 3 gigawatts of load in about 30 seconds, and it took PJM over 10 minutes to stabilize. Wood Mackenzie thinks only about 28% of the 1,066 gigawatts requested for US data center projects will actually get built; the rest is phantom demand. DOE has data centers going from about 4% to 9% of US power demand by 2030. I feel like for two years the constraint everyone talked about was GPU supply, but no”

If the water issue is “fake” or overblown, but it’s resonating with voters who are packing town halls and ultimately effecting the change you want (a broad slowdown in the construction of new compute) is that a problem?Congress isn’t going to get off its ass. There is momentum here. Who actually c”
“We built maybe two of the older less dense ones every year in most states, and that was driven by SaaS and cloud storage. The expected rate these AI datacenters would be built at if we just let these people go unopposed would be one every single week for the next four years. Something the size of a Wal-Mart Supercenter that uses the equivalent electricity of fifty to sixty four person households and depending on if it's open or closed loop cooled could use the equivalent of thirty households' wo”
Is there a better alternative for on-demand, on-location power generation?
“AI is draining the grid faster than anyone predicted, and I'm trying to wrap my head around what it actually means. In the US and Europe, data centers are going from a rounding error to a real chunk of total electricity demand. What does that actually change downstream — what new demand does it create? submitted by /u/Dan-100 [link] [comments]”
“The constraint on data centers stopped being land or capital and became interconnection queues and generation. I’m developing a behind-the-meter gas-powered campus partly because waiting 4–7 years for utility interconnection isn’t viable for AI timelines. Curious what others are seeing — is behind-the-meter generation a bridge, or the new normal? What’s your queue experience by region? submitted by /u/Geoge_MW_RFS [link] [comments]”
“Hey everyone, I covered power & gas at Citadel and I've been fielding lots of questions related to AI/data centers and their impact on the US power grid. Sometimes these questions were misguided, so I put together a comprehensive resource that covers everything from data center financing to actual power pricing methodologies. My hope is that readers will be able to better analyze different bills/proposals and build-outs within the US, since it's all very case-specific. Here's a l”
