Energy Efficiency - Computer monitors sold by star rating 2014–2024

Through the Equipment Energy Efficiency (E3) Programme, New Zealand and Australia develop common energy efficiency measures to regulate the energy performance of products in both countries.
Suppliers of products regulated under the E3 Programme provide Energy Efficiency and Conservation Authority with annual sales data for the period of 1 April to 31 March. This is used to help measure the shift in product efficiency over time and to calculate the energy savings to date from these improvements in energy efficiency.

通过设备能源效率（E3）计划，新西兰与澳大利亚共同制定能源效率措施，以规范两国产品的能源性能。受E3计划监管的产品供应商需向能源效率与节约管理局提供年度销售数据，数据涵盖自4月1日至3月31日的时间段。这些数据有助于衡量产品效率随时间的变化，并计算能源效率改进至今所实现的能源节约。
