This label is one of the most clearly defined labels. It is based on specific equations and calculations. You can use either the U.S. EPA Energy Star Rating or the EU Energ label, along with any local energy efficiency standard. In Barbados, the Barbados National Standards Institute is developing a local energy efficiency standard. You can use this label to buy appliances which will save you money on your electricity bill immediately. Due to the evolution of electronics most computers are energy efficient and may have a setting which you can use to reduce your consumption further. Phones are some serious energy hogs, that’s why it might be worth it to consider using portable charge ports which harness solar energy.
