"Notebooks are great for people who need mobile computing, but too many people use them all the time, even when sitting at their desks. The higher heat shortens the lifetime of electronics and battery," said Thomas Schramm, president of GreenMachineShop.com, of Ann Arbor, Mich. "The higher noise level and the unergonomic setup can reduce productivity and cause health issues. Using a desktop computer whenever possible and a laptop only when necessary is the best solution."
Ok, the electronics and battery life are shortened. Maybe, but most companies will get rid of these machines anyways on a two to four year cycle. Plus, since about 80 percent of the energy for any computer goes into its manufacture, I am having a hard time justifying two computers to save a little battery life. Maybe as a part of a comprehensive program... maybe. Unfortunately, this seems like a misguided attempt to sell more desktop computers.
What this really highlights is the fact that choosing the green alternative is complicated. I have been thinking for months now that we need a spreadsheet or some tools to help us make these decisions. I have to get on that.
