      People say this, but almost every time the time interval is left off it’s hours.

      Either way, the numbers in this meme are clearly made up. Most image generation uses fewer than 10 watt hours.

        This is new for me. Must be some engineering thing. I’m a physicist and and I feel guilty if I leave out some units just because, lol.

        Also, it literally is an energy unit used in measurements. It’s meant as a continious power. Ie. Your active imagination consumes around 12 watts of power, not “rendering one image”

              Power is energy per unit of time. Energy is power over a period of time. A lightning strike is about 1 GJ of energy. But it happens in a split second, so the power is far higher, say 100 GW. That is the output of 100 nuclear power plants. But only for 0.01 seconds.

              TNT is even more extreme. It can detonate in microseconds, so release its energy in a fraction of a millisecond. 1 kg contains about 4 MJ of energy, released in about 10 microseconds, a power of about 300 GW. That is about as much power as all of the USA combined needs.
