Energy Efficiency Overview
Energy efficiency refers to reducing energy consumption by using less energy to get the same useful output. For example, a 12-watt LED bulb uses 75-80% less energy than a 60-watt bulb but gives the same light. Energy-efficiency standards prescribe the energy performance of products, sometimes prohibiting the sale of less efficient products than a minimum level. They are often called minimum efficiency standards or minimum energy performance standards (MEPS).
- The Energy Efficiency Rating (EER) program measures and rates appliances’ energy efficiency based on electricity use. EER = BTU/hours of use/wattage usage. The lower the number, the more efficient. There are four tiers, with an advanced tier for exceptional products. Energy efficiency improvements use more efficient technology/processes or reduce losses. There are motivations to improve efficiency.
Energy Efficiency Regulations
In February 2016, the U.S. Department of Energy (DoE) enacted energy efficiency regulations that require external power supply to meet Energy Efficiency Level VI. To meet the current average efficiency and no-load power requirements mandated by the US Department of Energy (DoE) under the Level VI standard and it also conforms to the trend of green, environmental protection and energy conservation.
Benefits of Energy Efficiency
The many benefits of energy efficiency include:
- Environmental: Increased efficiency can lower greenhouse gas (GHG) emissions and other pollutants, as well as decrease water use.
- Economic: Improving energy efficiency can lower individual utility bills, create jobs, and help stabilize electricity prices and volatility.
