Energy is a quantity, it exists independently of time. An "instantaneous energy use" only makes sense if you tell in what (presumably very small) amount of time the energy was used... and then what you are measuring is not an energy but a power, for which we already have an interface.

Nitpicking for consistency: millisecond (no trailing s). What values do you expect for this entry? I am wondering if it's safe to use millisecond as a unit. Is it unlikely that a future chip will support averaging intervals below the millisecond? + RW
