A laptop uses at least a fifth of the energy of a desktop computer. In addition, the smaller size of laptops means less packaging and more versability for your computer.

A typical laptop computer uses 15 watts of electricity, and it powers down often when not in use. A typical desktop uses 130 watts of electricity, including the monitor. In addition, a laptop is the perfect choice for individuals living off the grid. There have been many times when our power has been low or down, and my laptop's battery has enabled me to keep working.

Don't be fooled into thinking your computer's screen saver saves energy. Unless the screen or backlight on a laptop actually turns off, a screen saver uses as much power as word processing. Also, don't forget, you can save additional energy by adjusting your computer's sleep mode to turn on more frequently.

I read yesterday about (over at Treehugger.com) about a cardboard case used on a new computer instead of a plastic one. I feel that the motherboard , connections inside ect would last longer because of the dispersion of heater is more effivtive. The use of electricty is in direct proportion to how long you use the computer and more to the point how long it is left on when not in use. Turn it off when not being used!!!!!
