Reducing the amount of power consumed by a computer not only reduces the cost of the electricity itself, it also reduces the efforts required to control the heat surrounding the computer. Reducing power consumption also can extend the effective life of the hardware you use.
The United States Environmental Protection Agency (EPA) has established Energy Star® guidelines for computer products. Other nations have issued similar energy efficiency guidelines. To meet these guidelines, hardware products are designed to use power efficiently.
The Power Management software provided in the Solaris operating environment works in conjunction with the hardware to reduce overall consumption of electricity. In some cases, you may need to use this software for your workstation to meet the Energy Star guidelines that apply to that hardware.
As an Energy Star Partner, Sun Microsystems, Inc. has determined that its hardware products that have the Energy Star symbol on the shipping box or on the product itself meet the Energy Star guidelines for energy efficiency.
