Computer Factories Are the Energy Hogs

coondoggie writes "The main idea behind saving energy in the high-tech world has been to buy newer, more energy efficient devices, but researchers say that may be the wrong way to look at the issue, since as much as 70% of the energy a typical laptop will consume during its life span is used in manufacturing the computer (abstract). More energy would be conserved by reducing power used in the manufacturing of computers, rather than reducing only the amount of energy required to operate them, say researchers from Arizona State University and Rochester Institute of Technology."

Re:How much energy to manufacture a solar panel?

The energy balance analysis in the case of the Vestas V90 3.0 MW shows that, for an offshore wind turbine 0.57 years (6.8 months) of expected average energy production are necessary to recover all the energy consumed for manufacturing, operation, transport, dismantling and disposal.

Unfortunately, most laptops are not manufactured in Britain, but in countries with much cheaper (and dirtier) electricity.
