I saw this gallery on Golfdigest.com where Louis Oosthuizen describes his swing sequence and thoughts to generating power and clubhead speed.

According to Louis: “I was never the biggest or strongest guy growing up on the southern cape of South Africa, so from the beginning I knew I was going to have to create clubhead speed with good fundamentals and efficient technique. So those are things I’ve always paid attention to. At 5-11, 160 pounds, I’m still on the smaller side for a tour player, but I can carry my driver almost 300 yards and hit my 7-iron 180, and that’s using what I would call a comfortable swing. Rory McIlroy hits it even longer, and he’s about the same size I am. Watch a sport like rugby or basketball, and the pitch or court is filled with guys who are huge and super fast, and they’re doing things you can’t even try to copy. But golf is different. All golfers can improve in the basics and find more “easy power”—the kind that comes from good rhythm, stability and the right sequence of motion, not by going after the ball as hard as you can with brute force. Here I’ll show you some of the things I work on to keep my swing in balance and working at optimum speed.”

His main keys for “HOW YOU CAN CREATE MORE SPEED WITH LESS EFFORT” are:

• Keep your arms soft and make a full hinge to the top.
• Start your hips first and let them pull your upper body.
• Push against the ground keeping your feet flat.
• Let the club speed through without forcing it.

I think everyone can learn from this.
