ENVIZNAbout
What ENVIZN covers, where the numbers come from, and who writes it.
ENVIZN covers infrastructure: the grids, data centers, factories, and buildings modern life depends on. Trade press covers the components and general press covers the story, but neither usually connects a chip shortage to a substation queue to a permitting calendar, which is where most of the interesting problems actually live.
Where the numbers come from
Primary sources first: regulatory filings, utility planning documents, JEDEC and ASHRAE standards, technical papers, earnings transcripts. Estimates are labeled as estimates and the assumptions sit next to them. Every learning track carries a sources note saying what it drew on and where teaching values were rounded.
ENVIZN does not sell a product, and no page here promotes one.
The four subjects
Energy
Generation, fuel, markets, and interconnection queues. What a megawatt-hour costs to produce, and how long it takes to get permission to deliver one.
AI
Models, training runs, and inference economics. What the workload actually demands in compute, memory, and power, checked against announced figures.
Compute
Accelerators, memory, and the halls built around them. The hardware that consumes the power and does the computation.
Power
Substations, switchgear, transformers, and cooling. Everything between the grid connection and the chip.
Open questions
ENVIZN's long-term agenda is a set of unresolved questions, and most of the work on this site is an attempt to get further into one of them.
- After sixty years of getting cheaper through smaller transistors, computing now gets cheaper by building bigger systems.What changes when land, water, and transmission capacity replace lithography as the binding constraint?
- The grid was built for load that is predictable, daily, and spread across a map.AI load is less predictable, does not follow a daily cycle, and is concentrated at a few sites. Will the grid adapt to AI, or will AI load have to behave like a grid asset?
- If inference gets cheap enough to run continuously, most software stops being something you open.What is the interface to a machine that is already perceiving before you ask it anything, and what does that do to attention?
- Infrastructure decisions once made by utilities and regulators on twenty-year cycles are now being made by a handful of companies on quarterly ones.What does that do to systems everyone has to share?
- Every megawatt of new load is built at a specific site, next to specific neighbors.Deciding where it goes also decides who gets the capacity, who carries the cost on their bill, and who lives beside the substation.
