1) The storage is the grid. 2) The efficiency of a wind farm matters a lot less than the availability and quality of wind. 3) Yes we have "plenty of methods for making power" but if that power is only made at midnight on every fourth tuesday then you're well beyond storage problems because nothing holds megawatts for days at a time. 4) You're discussing compressed air energy storage or pumped storage hydroelectricity both of which I'm sure WanderingEng could talk a lot more knowledgeably about... as well as DC power transmission, which kinda licks the "grid" problem.
