One way to reduce your carbon footprint at home is to use less electricity. You can do this by turning off lights when you leave a room. Using energy-efficient light bulbs like LEDs can also help. These bulbs use less electricity and last longer than old-style bulbs. You can also unplug devices when you're not using them. Even when turned off, many devices still use a little bit of power if they're plugged in. This is called standby power or vampire power. By using less electricity, you help reduce the amount of carbon dioxide released into the air.
