"GW per year" and "TW per year" is nonsense.
Watts is a unit of power, which is energy per second.
Im not sure Musk even understands what a Watt is, he just wants to sound smart.
Because it's not kilowatt per hour (kW/h), it's kilowatt hours (kWh). It would be fine to say GW years, but then the question would be over how long? Most likely one year, which gives us GWy/y = GW.

So what is a kWh then?
That's watts multiplied by time, aka energy.
So if you can have a kilowatt per hour, then why can't you have a gigawatt per year?

A unit of measurement that only makes sense in the context of domestic electricity meters. Supposedly to make it easier for consumers.
Or 3,6 Kilojoule.
