The "Significant Energy" list in the battery menu is a new feature of 10.9. It shows what programs might be using up a lot of energy.
Most of the time you'll just see some programs you are currently using, which is perfectly normal as they will obviously have to use more energy when you are working with them.
However, if there programs in the menu that are running in the background but you aren't really using them, you might save some battery power by quitting them.
thanks for the explanation, but do you think is normal for safari to be up there? i only have 3 tabs of forum web pages
