The first is that at any given point in time, my instantaneous energy use is offset by renewables.
The second is that over some period of time (e.g., one month) my aggregate energy use is offset by renewables.
The second is MUCH easier. When people say things are 100% renewable, I generally think they mean the second thing. This is a bit of a fudge (not wrong but not 100% level).
