How to sync Google Account every one hour? If I turn on sync of my Galaxy Nexus, it makes batter life short. But I need sync my Google Account. So is there a way I can sync automatically every one hour?
There are several approaches to accomplish this. Ready-to-use tools like JuiceDefender or GreenPower "stutter" data (i.e. turn data &amp; sync on only in certain intervals, as you requested). The same could be accomplished using an automation tool like tasker or Llama, which then could be used for other automation as well.

Apart from that, you might want to check what you've enabled to sync (see: Settings→Account &amp; Sync). Maybe you don't need to sync all of that, so you can uncheck parts. I found that about have the stuff enabled there by default I didn't want or need. Less stuff to sync also means less power needed for the job. And bandwidth saved as a side-effect.
