What are terra watt hours?

Answer:
Watt hour is a measurement of energy use, something that's pulling one watt during one hour. Tera is a multiplier, 1x10^18, so it's either something pulling one watt for that many hours, or it's something pulling that many watts for one hour or something inbetween.
