Looking for the greenest television set? We've had to sort through a complex set of resources in the past to help you buy that green TV. Now, EPEAT has added televisions to its equipment registry. We hope this will bring some clarity to this category.

The US ENERGY STAR program looks only at energy efficiency and not other sustainability factors. About twenty set-top boxes (STBs) or cable, IP, or satellite from seven manufacturers came in at less than 65W in the program's Total Energy Consumption (TEC) metric. This is a big improvement from two years ago, when our top twenty cut-off was 100W.

We've updated our printers post with the new EPEAT registry. You can find other 'greenest gear' categories in the block to the your right in the full post.

Green-certified computer displays are now too numerous to list in table format. Here are where to find them:

We've added newer rankings for mobile and smart phones, but left the original ones below for those looking to reuse an older unit.

EPEAT® - "the definitive global registry for greener electronics" - simplifies its twenty-three required IEEE 1680 criteria and twenty-eight optional ones into a simple Bronze-Silver-Gold designation. EPEAT Gold models meet all required criteria and at least 75% of the optional ones. ~20* manufacturers are now offering over 1200* EPEAT Gold products registered for the United States.

Desktops and workstations are still widely-used in enterprise computing, particularly for demanding applications, although some of these models are targeted to the consumer. Nine manufacturers are offering over 170 models in the EPEAT Gold database. Ace, All-In-One, Dell, HP, and Lenovo offer the most choices; Ace, Grace, Verdio, and Wipro are the latest to have products on one of these green rankings. BenQ and MDG no longer have desktops listed by any ratings systems, so they have been dropped from this table.

Notebooks, including laptops and netbooks, is the most well-reviewed e-gear category. HP models are noted by all five sources; Apple and Toshiba by four. The EPEAT Gold database includes over 670 models for the US; Samsung, Sony and Toshiba offer the most.

We found back in 2010 that the European market for Green ICT products had many local standards with few certified products. That did not appear to best serve sustainability-oriented computer buyers, consumer or enterprise, who needed to make practical purchasing decisions incorporating sustainability. The number of products certified by these organizations appears to have declined in recent years. Only Sweden's TCO Development showed significant growth its certification database.

While much of the green computer focus worldwide is on laptops, UK companies are doing interesting things with desktops.

Aleutia offers low-power units that "are designed to easily connect to solar power and work in remote places." Case studies include Africa and Central Asia.

VeryPC promotes its Broadleaf desktop as "categorised as ‘Class Leader’ by DEFRA Quick Wins", "BFR, PVC and halogen free in line with ECMA-370, the environmental standard", "the only desktop PC to be endorsed by the Energy Saving Trust Recommended scheme".
