  1. Computer Factories eat way more energy than running the devices they build By Guangfei Liu

  2. Idea behind saving energy • Buy newer, more energy efficient devices • It is the wrong way to look at the issue • Researchers show that 70% of the energy in a laptop is used in manufacturing

  3. Manufacturing a laptop emit carbon • 227 to 270 kilograms per laptop • Close to manufacture of a refrigerator • Requires 3010-4340 MJ of primary energy

  4. Ethical issure? • Influence the environment • Waste of energy • Waste of materials

  5. Solution • To extend lifespan mitigate manufacturing energy use • Questions: • Is there any other solutions? • Do you think we should buy newer computers or reuse our computers? • What do you think computer factories should do?
