Computer and Server Buyers

Affiliate membership is free and open to any type of organization. Members commit to buying high-efficiency systems for a majority of their corporate PC and volume server computer purchases, and to using power-management tools on their existing PCs.

Within the program’s first year, participating businesses should establish purchasing criteria that all new corporate PCs meet the ENERGY STAR rating, and similarly require 85% minimum power-supply efficiency for volume server purchases.

In subsequent years, we’re asking companies to purchase systems with increasing levels of efficiency (see table). We expect that the price premium for meeting the high-efficiency target ratings in any year will be less than $20 per PC and less than $30 per server and will decline toward zero over time. The details of commitments requested from participants are described below.

The table below lists the minimum percentage of total procurements requested from Climate Savers Computing Initiative participants at each efficiency level in a given year.

These purchasing criteria exclude non-standard workstations and specific-function platforms. The purchasing criteria are based on availability of PCs and servers that meet the program criteria at a price the member company considers reasonable, while also fulfilling the member’s business needs and allowing them to work with their supplier(s) of choice.

If you are unable to meet the program criteria but still want to participate, please contact us at

There’s something in it for you, too.

Even at modestly higher prices, more efficient computing systems will pay for themselves in reduced energy costs.

For example, a savings of just 20–30 watts in power consumption translates to a savings of 60 kWh per year for a desktop system that is on 2,000 hours per year (40 hours/week, 50 weeks/year). At $0.12/kWh, this translates into a savings of $7.20 in direct energy costs. Factoring in the savings on air-conditioning costs, the total savings is approximately $10/year. At a cost premium of less than $20 for PCs and less than $–30 for servers, this additional efficiency will pay for itself in 2–3 years. Systems that remain turned on all the time typically pay for themselves within the first year of use. The savings for servers will typically be significantly higher than for desktops, resulting in a much shorter payback period.

And that’s just the beginning


Today’s computers, such as desktops and notebooks, also have many power-saving capabilities built into them. Examples are the “sleep” and “hibernate” modes that can significantly reduce the amount of energy consumed during inactive states. When these capabilities are utilized during periods of inactivity, it reduces the overall amount of energy consumed by up to 60%. This translates to a savings of $11-15 per system per year at an energy rate of $0.0885/kWh. Factoring in the additional savings on air-conditioning costs, the total savings could be as much as $18-26/year.

In addition, products that meet or exceed the efficiency standards of the Initiative will qualify for existing utility rebates under the 80 PLUS program and the ENERGY STAR program. These rebates can partially or completely offset the cost difference. We will work with utilities and regulators to make these rebates available to all purchasers of high-efficiency computers and to enhance the rebates for systems that exhibit the highest levels of efficiency.

For companies who have committed to carbon reduction or neutrality, the Initiative has the added benefit of helping to reduce the number of carbon offsets they’ll need to buy. Employing aggressive power management on 1,000 PCs can save approximately 118.26 tons CO2 per year. Using an example cost of $10 per carbon credit, that results in an annual savings of $1,182 in carbon offset costs. These changes are among the most immediate actions companies can take to make a real impact on both the environment and their bottom lines.

Membership in the Climate Savers Computing Initiative also gives companies an opportunity to demonstrate their leadership and work with visionary organizations such as Dell, Google, HP, Intel, Lenovo, Microsoft and World Wildlife Fund. And your leadership will pave the way for more companies and individuals to follow, so that together, we can achieve our goal of reducing computer power consumption by 50 percent by 2010. That represents a 54-million-ton reduction in global CO2 emissions from the operation of computers – which is equivalent to taking 11 million cars off the road.

 





Did you know?

U.S. college students could save more than 2.3 billion kilowatt hours per year of electricity by enabling power saving features on their desktop PCs. That equals an annual savings of more than $200 million in energy costs and a 1.8 million-ton reduction of CO2 emissions from the operation of computers –equivalent to taking more than 350,000 cars off the road.7
