15.4.7.8.4. More efficient components

Try these first

1. 1.

   What is the typical efficiency percentage of desktop power supplies?

   Hint

   Think about how much of the energy is wasted as heat.

2. 2.

   How do smaller hard drives compare to larger ones regarding energy use?

   Hint

   Consider the physical size and its impact.

3. 3.

   What is the typical efficiency of a standard desktop power supply?

   • 60-65%
   • 70-75%
   • 80-85%

   Hint

   Remember the power waste principle.

4. 4.

   True or False: Smaller hard drives consume more power than larger hard drives.

   • True
   • False

   Hint

   Think about the size-to-power relationship.

5. 5.

   Evaluate how upgrading all components of a desktop (PSU, storage, display) to energy-efficient options would impact total energy costs for a year, given specific usage patterns.

   Hint

   Think about the differences in costs between regular and efficient models.

6. 6.

   Discuss the potential challenges of transitioning to all efficient components in a legacy computing infrastructure, including budget, training, and integration issues.

   Hint

   Reflect on both immediate costs and long-term savings.
