HOW CAN WE SAVE ENERGY?
Every day we waste lots of energy that we could save if we were more careful and change our mentality of consumer.
Here are some possibilities of saving energy:• Switch light bulbs by compact fluorescent bulbs.• Unplug unnecessary devices from electrical outlets.• Select the most energy-efficient models when you replace
your old electrical appliances.• Turn the refrigerator down, refrigerators account for 20% of
household electricity use.• Whenever possible, walk, bike, or use mass transit.
