Any idea why the energy impact from time machine would be so high?
You may have touched a lot of files at some point and it may have taken a while to back up all of them.
I wouldn't worry about it unless it takes up a lot of power every time you back up.
And hopefully you have enabled back up during when you are plugged into AC, not caring about power consumption, and not on battery.
