Global Electricity Demand Doubled in 44 Years — Before AI Even Showed Up. Here's What That Means for Your Rates.

There's a popular narrative right now that AI data centers are single-handedly responsible for the grid pressure homeowners are feeling in their bills. The reality is more complicated — and arguably more important to understand. According to International Energy Agency data, global CO2 emissions more than doubled between 1971 and 2015, rising from 14.1 gigatonnes to 32.3 gigatonnes. Over that same period, electricity and heat generation grew from 27% to 42% of all global emissions — by far the fastest-growing slice of the pie. All of this happened before a single modern AI data center existed.

What Actually Drove the Growth

The story behind this growth is straightforward: the world electrified. Refrigeration, air conditioning, computers, televisions, industrial automation, and eventually the early internet all ran on electricity, and global population and economic growth meant more homes, businesses, and factories needed power every year. Electricity demand grew faster than almost any other form of energy use precisely because it powers nearly everything in a modern economy. This matters because it reframes the conversation. The pressure on the grid — and the rate increases that come with it — isn't a new phenomenon created by artificial intelligence. It's the continuation of a multi-decade trend that utilities have been building infrastructure to keep up with for years. Wildfire hardening, transmission upgrades, and substation expansions that show up as line items on your SCE bill are, in part, a response to this long-running demand growth.

Now Layer AI on Top

Here's where it gets more urgent. AI data centers represent a new, concentrated, and extremely power-hungry source of demand layered on top of a grid that was already straining to keep pace with decades of growth. A single large AI data center campus can consume as much electricity as hundreds of thousands of homes. Multiply that across the dozens of new facilities being built across the country, and you have a demand shock arriving on top of an already-stressed system. Utilities and grid operators are now openly warning that electricity demand could grow significantly faster over the next decade than it has historically — Edison International has cited projections of demand rising as much as 80% by 2045 in its own service territory, driven by a combination of electrification, EVs, and large new commercial loads like data centers.

What This Means for Homeowners

For California ratepayers, the practical takeaway is this: rate pressure isn't temporary, and it isn't solely about any one cause. It's the product of a long historical trend in electricity demand that's now accelerating due to AI infrastructure, electrification mandates, and continued population growth — all while utilities invest heavily in wildfire mitigation and grid modernization. Homeowners who generate and store their own electricity through solar and battery systems are, in effect, opting out of a portion of this demand growth story. Every kilowatt-hour you produce and use yourself is one less kilowatt-hour you're competing for against a data center, an EV charging network, or your neighbor's air conditioner during a heat wave.

Bottom Line

The grid was already under pressure long before AI entered the picture — the data goes back over 50 years. Understanding that history helps homeowners see rate increases not as a temporary blip, but as part of a structural trend that makes energy independence more valuable with each passing year.
