Use energy efficient light bulbs for our most-used lights. When we leave a room, turn off the light.
Turn off our computer/laptop when we are not using it.
Save water. Take quicker showers. When brushing teeth we should not leave faucet running.
Use reusable cloth shopping bags that are made from plant fibers. Whenever possible, walk, bike, carpool, or use public transportation.

Old clothes can also be made into other items such as cushion covers.
Old electrical equipment: Donate old electrical equipment to schools or community centers so that others can reuse them.

Jars and pots: By cleaning glass jars and small pots, we can use them as small containers to store odds and ends（零星物品）.
