Care to join us on our mission? Here’s how.

To participate in the Climate Savers Computing Initiative, we ask your company to commit to optimizing its existing systems (by widespread deployment of power-management tools, for example), and pledge to purchase more energy-efficient systems in the future.

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.

We are currently developing additional Program Criteria for years 2-4 to include a minimum efficiency level for motherboards, and may consider adding criteria for mobile platforms in the future.

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.

Minimum PC efficiency targets and purchase commitment level

  Year 1: July ‘07 – June ‘08 Year 2: July ‘08 – June ‘09 Year 3: July ‘09 – June ‘10 Year 4: July ‘10 – June ‘11
Energy Star 4.0 100% 100% 100% 100%
85% PSU   >=20% >=80% 100%
88% PSU     >=20% >=80%
90% PSU       >=20%
For example, in year 2 all of your purchases should fulfill the EnergyStar 4.0 requirements, and at least 20% of them should be at least 85% efficient.

89% PSU   >=20% >=40% 100%
92% PSU       >=20%
Personal Computers and Volume Servers are mainstream Personal Computers and Volume Servers deployed by corporations and do not include non-standard workstation or specific function platforms.  The suggested purchasing commitments are based on availability of PCs and servers that meet the program criteria at a price that you consider reasonable, while also fulfilling your company’s business needs and allowing you to work with your 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.

Join us and make a pledge to computer efficiency

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 could translate to a savings of up to $15–$25 per year at $0.12/kWh. Factoring in the savings on air-conditioning costs, the total savings would be approximately $25–35/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.

Reducing the power consumption of PCs and servers has secondary benefits throughout an organization and the larger community. It reduces electrical and air-conditioning loads in office buildings, data centers and homes, thus reducing the strain on regional generation facilities and the electrical grid. Last but certainly not least, it reduces emissions of greenhouse gases and other pollutants.

Initially, high-efficiency systems may cost slightly more than standard systems; we expect this difference to be less than $30 per system. However, we are confident that as unit volumes increase, these costs will drop to near zero.
