HP Leads the Pack on New Energy Star Standards

The Energy Star 4.0 standard is charted to “go live” this July, and today HP has released three new computers that will make the grade!

In many ways, these computers are similar to the previous Energy Star-labelled systems. Improvements, however, can save consumers between $6 and $58 annually in energy costs, according to HP’s statement.

There are two major improvements required for Energy Star 4.0 compliance. First, the power supply must convert 80% of the power it draws to be used by the PC. Most PCs hover around 70% efficiency at the power supply, so this will be a nice improvement.

More importantly, the 4.0-compliant PC must duck under the new wattage requirements when in “Idle Mode”. Idle mode is defined as a fully-awake, booted computer not running any other applications. The limit for  a basic PC is 50 watts in idle mode. There is built-in leeway for multi-core processors and fancy graphics cards.

Since the Energy Star program is entirely voluntary, HP’s compliance probably reflects the increasing demand for energy efficiency, not just among home consumers, but in business to business sales, as well. Increased awareness of global warming, and ever-rising energy costs are probably factors in this trend.

The three HP computers which meet the 4.0 specs are:

The dc5700 & dc7700

(Intel Core Duo processor, an 80GB hard drive, 1GB of memory, a DVD/CD-RW drive and Microsoft Windows XP Pro.)

The dc5750

(AMD Athlon processor and 512MB of memory, as well as an 80GB hard drive, a DVD/CD-RW drive and Microsoft Windows XP Pro.)
