What if you could help the environment just by making one simple decision? If you buy a notebook computer instead of a desktop PC, you’re well on your way to helping save the planet. For starters, a notebook is smaller than a desktop, so it has less environmental impact at disposal. In fact, the trim size of a notebook means it only uses the bare minimum in computer components, such as one hard drive, one CD/DVD drive, and one graphics adapter. By contrast, a desktop might have two graphics cores (including one on the motherboard and one external core), extra hard drives, more than one CD or DVD drive, and other components, such as a flash card reader, USB hub, and extra video input ports. The proliferation of notebook computers is also less harmful to the atmosphere, as manufacturing plants dedicated to producing smaller computers with fewer parts release fewer emissions.
Just as importantly, mobile processors are designed for long battery life, which means they are state of the art in terms of power management. Laptops don’t use as much power as a desktop, mostly because the processor is only drawing about 30 to 35W or less, compared to about 65W or more for a desktop CPU. (The ancillary benefit is that your electrical bill won’t be quite as high if you use a laptop.)
In most cases, a laptop also complies with European regulations on lead-free computing, such as the RoHS (Restrictions of Hazardous Substances) and WEEE (Waste Electronic and Electrical Equipment), which is a mandated disposal code in Europe. Lead is used primarily in soldering parts together on a computer, but RoHS and WEEE encourage companies to use other means for building a PC.
