5. Use the microwave to heat food
The use of a microwave is much more energy than using a gas or electric oven. You can save about 60% on your electricity bill using your microwave for one hour a day instead of an electric oven. But when you are not using microwaves, remember to unplug it as it still use electricity when it is plugged.
6. Use sensor
Sometimes you turn the lights in your pantry, closet, or hallway and accidentally leave them. You can install motion sensors in your house to automatically close the lights. Occupancy sensors are also a good option, but you should give them a place where they can easily find you or someone else in any part of the living area.
