Replacing high consumption, old, and damaged appliances with low consumption, new and healthy ones is the one of useful solutions to reduce amount of energy usage in daily life. In addition, using high consumption appliances, such as laundry and dishwasher at off peak times would be able to decrease costs and energy usage toward environmental aims. It is an undeniable fact that, considering energy label on appliances would guide people in purchasing appropriate appliances again. According to all of mentioned cases, the more attention to the more preparation of such tables for water and energy usage, could help to optimize consumption, which will play a key role and influence in sustainable development in each and every society.
