Trimming down my electric bill—any tips?

My electric bill's been creeping up lately, and I'm kinda scratching my head over it. I've already swapped out most bulbs for LEDs and try to unplug stuff when I'm not using it (though I admit, sometimes I forget, you know?). Wondering if anyone's got some clever tricks or gadgets they've tried that actually made a noticeable difference. Maybe something simple I'm overlooking?
