Dell has announced that by 2010 it intends to cut energy consumption in all of its PCs by 25 percent.

"Our customers are inspiring us to address the environmental challenges facing our planet," said Albert Esser, Dell's vice president of power and infrastructure solutions.

"We've listened to them and are designing next-generation technologies that dramatically reduce energy consumption, drive meaningful cost savings and help achieve a low-carbon economy."

Dell plans to trim energy consumption usage by changing the circuit designs, fans and power management features in its computers. The company said it also is working with its vendors to get more energy-efficient components, like chipsets, power supplies and memory.

Last month, Dell chairman and CEO Michael Dell said the company is working on a desktop computer that will use 70 percent less energy and be 81 percent smaller than a standard minitower machine in use today.

Noting that the machine will be the "company's smallest and most environmentally responsible consumer desktop PC", Dell also said it will come in recycled and recyclable packaging.
