Calculator
Tech Republic offers a free worksheet to help you determine various costs for monitor
power. It allows you to do the following:
• Determine how much you spend on electricity to power your existing monitors.
• Compare new LCD and CRT monitors to determine which option is less expensive.
• Compare different models of the same type of monitor to determine which one
carries the lowest total cost, when power is considered.
• Compare the same monitor under two different operating scenarios. For example,
see how much cost savings you could achieve by implementing a monitor’s sleep
mode instead of leaving it running at full power when not in use.

The worksheet can be found at Link 3-2. The download does require a free membership
on their website.
