generate more power

One of the key elements in the downswing is to keep your head in the same position. Begin your downswing with the hips and keep your head behind the ball until your follow through. Do not use your right hand to try to generate more power. The power in your golf swing will come from the leverage in the angle between the club and your wrists.
Try to hold the angle between the clubs and the wrists as much as possible in order to generate maximum power.  Upon further examination you will notice that the angle of the ground affects the ball, and you can put spin on your shot to alter its course.  Each character has different stats in regards to how far they can drive the ball, the level of impact they can get, etc. 
These stats are affected as you progress through the game by various items that you can outfit the characters with.  The hips must act as a counterbalance in the swing. As your upper body tilts forward to the ball, the hips push back to counterbalance. In order to maintain your spine angle throughout the swing, the hips need to stay pushed back as they rotate in swing.
This will allow you to make solid contact with the ball.  I liked the Merrill ad featuring Annika and the Srixon ball ad that includes a pink sleeve of balls. I like that the Golf Channel ad has a junior girl golfer in it. I was glad to see Stina Sternberg, the former Senior Editor at Golf for Women magazine, with her own column writing about a wife's problem with her husband's golf. 
If you've ever played baseball you will know what I am trying to say. When you swung a baseball bat did you worry about where your right elbow was at, or what your hips were doing? No. You reacted to the ball coming in and "naturally" responded by swing the bat and trying to hit the ball.
