Unplug appliances when you're not using them. Using a power strip makes it easier to conserve electricity because you just have to unplug one cord instead of many. Also unplug any chargers that aren't in use because they still use electricity even when they're not actively charging something.

Set your thermostat at a reasonable temperature. Set it as high or as low as you need to be comfortable, but don't heat or cool excessively.

Use your appliances efficiently to conserve electricity. Refrain from opening your oven unnecessarily because it has to work harder and use more energy to heat back up; only run the dishwasher when it is fully loaded; adjust the water level on the washing machine for smaller loads and clean out the lint filter in your drier before every load.

Turn off the lights when you leave a room. If your lights have a dimmer switch, dim the lights as much as possible. Also use sunlight to your advantage during the day and turn off artificial lighting.

just four steps, greenies! :D
