> Heathrow is massive and uses a lot of power (1-2MWh/day)

It's 3 orders of magnitude more: 1-2GWh/day.

Yeah I munched the maths but yours is 10 years old!

The 2022 version of that sustainability report puts their annual bought in electricity at 272,610 MWh, 747 MWh per day.

My wonky maths aside, it's amazing how much energy they've saved. In your link, the switch to LEDs alone saw a 20% total power reduction. I'm sure I've seen electric vehicles there so I'm surprised this number is still apparently in freefall. Perhaps they're doing more local generation (eg) PV

While we're doing wacky units for energy instead of the joule, I'd personally prefer roughly 360 DeLorean's per day (assuming the 1.21 gigawatts are required for roughly 10 seconds)
