Green is ground, black is hot, and white is neutral. Neutral is typically tied together at the main service box and the box is also grounded, but there can be a potential between neutral and ground by the time it gets to the load, so treat the white as if it is hot too.
Black goes to the brass terminal. White goes to the silver terminal, or the ribbed side of the cord.
