Data centers use no more than 1.5% of electricity globally[1], and a long LLM query uses only a little more than 5 minutes of general laptop use ~3x the energy of running an LED light for 5 minutes.

So you’re saying we could significantly cut energy use globally by limiting data center build outs?

1.5% is a //huge// amount. If it was a “drop” in your bucket, it would only hold 67 more of those drops.

1.5% of electricity. That's a significant difference. Only about 1/7th of all our energy usage is electricity

1.5% of global energy use would be a shocking amount. Aviation is at about 3%. 1.5% of global electricity is about 0.2% of global energy use, a much more manageable figure

Wow, even with that being electricity rather than energy, that's orders of magnitude more than I would have guessed. That's a tremendous amount of electricity.

> ~3x the energy of running an LED light for 5 minutes.

Why would this not be the energy of running an LED light for 15 minutes?

1.5% of electricity, not energy

that would be 0.3% of global energy use

When all is said and done, data centers are going to be complimentary to green energy. They can spin up and down to buffer non-linear power nodes.

They also represent investment in economic growth that doesn't come from resource extraction or travel or manufacturing.

Ah yes, "just" 485 TWh, equal to all electricity consumption of Germany. Drop in the bucket
