In my previous post I talked about the ENERGY STAR database for energy efficient office equipment. To be an ENERGY STAR qualified monitor it must use not more than 23W per mega-pixel, the number of mega-pixels is rounded up. For example a monitor with a resolution of 1280x1024 has 1310720 pixels, this is rounded up to 2 mega-pixels, so must not consume more than 46W.

I have picked two monitors, one standard and one wide screen from the ENERGY STAR database which are available today and are very energy efficient.

Lenovo L1900 1280x1024 19" Monitor

This monitor consumes 17W typically and no more than 24W maximum. It also has good environmental credentials having 50% less mercury content than typical monitors of its class.





You can find the cheapest price here.

LG W2252-TE-PF 1680x1050 22" Monitor


This monitor only consumes 22W in normal use and 0.3W in sleep mode.

How do you know if the latest bit of office equipment you're considering buying is energy efficient? It's not easy, you may be lucky and have the manufacturers specification available. If not you could look for equipment with the ENERGY STAR logo.







The ENERGY STAR program is an agreement between the Environmental Protection Agency for the US and the European Commission for the European Union to provide a common set of energy efficient specifications for office equipment. They maintain a database of equipment that has met this specification. Manufacturers who produce equipment that meets their specification are allowed to display the ENERGY STAR logo.

The limitation of the ENERGY STAR program is it only indicates that the equipment meets the standard laid out in their specification. If you want to know if the equipment is the most efficient available then you need to consult the ENERGY STAR database. Here you'll find information such as power consumption on full load, standby off etc.

The database for the EU can be found here
