AI and air conditioners are colliding as temperatures rise.

It’s crunch time for the grid this week. As I’m writing this newsletter, it’s 100 °F (nearly 38 °C) here in New Jersey, and I’m huddled in the smallest room in my apartment with the shades drawn and a single window air conditioner working overtime.

Large swaths of the US have seen brutal heat this week, with multiple days in a row nearing or exceeding record-breaking temperatures. Spain recently went through a dramatic heat wave too, as did the UK, which is unfortunately bracing for another one soon. As I’ve been trying to stay cool, I’ve had my eyes on a website tracking electricity demand, which is also hitting record highs.

Climate change is bringing extreme heat and testing the limits of what people can tolerate.

We rely on electricity to keep ourselves comfortable, and more to the point, safe. These are the moments we design the grid for: when need is at its very highest. The key to keeping everything running smoothly during these times might be just a little bit of flexibility.
