Buy Energy Efficient, Environmentally-Friendly Computer

Is your computing life boring? I guest it’s time for you to shop for a brand new computer. This time you might be thinking of a high performance pc with all the good stuff in it. But wait a second cause you might end up buying an inefficient  pc.

Before you buy consider the following:

Energy Star Compliance

System meeting the standard wear Energy Star badge, which guarantees that certain energy consumption requirements are controlled. When fully powered on, their power supplies must be able to convert 80 percent of incoming electricity for use by the PC.

Processor

Intel and AMD have been working for years to reduce processor power consumption. The Intel Core 2 Duo desktop processor is up to 40 percent faster and more than 40 percent more energy-efficient than its single-core predecessor. It optimizes power consumption by powering up processor components only when needed.

Intel claims that its Centrino Duo laptop technology is twice as fast as previous versions, yet consumes 28 percent less power. Also very efficient are Intel’s Pentium M and Celeron M processors and AMD’s Turion 64 and dual-core Turion 64 X2.

Operating System

Choose an Operating system that is programmed to reduce energy consumption or at least capable of shutting down several peripherals when not needed, power saving options so to speak.

Graphics Cards

Graphic cards are power hungry hogs. They can consume up to 100 watts of power at peak performance and double that figure for dual-graphics card configuration. When not inclined at gaming, the embedded video card on a motherboard is enough.

Power Supply Unit (PSU)

Most desktop computers when fully operational consumes 150 to 250 watts of power. Why do you need to buy a higher wattage when you do not need the extra. Choose a power supply unit that is capable of adjusting its power output according to the demand of the system.

Size of the Computer

Yes, size really matter. Laptops consume 5 times less than a desktop. A 19” CRT consumes about a hundred watts while an LCD is about 45 watts of the same size.

Environmental Compliance:

	ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.
	EPEAT is a system to help purchasers in the public and private sectors evaluate, compare and select desktop computers, notebooks and monitors based on their environmental attributes.
	International Organization for Standardization (ISO) rules dealing with reducing energy use, limiting waste and increasing recycling.
	The RoHS Directive stands for “the restriction of the use of certain hazardous substances in electrical and electronic equipment”.  This Directive bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.
