Turn Off Your Computer?

Sometimes for convenience we leave our computers on at night. However, we have heard for years that this wastes energy.
Here are some of the facts I found while investigating this topic.
1. The only way that a computer uses zero energy is when it is unplugged. Otherwise, it is using 2.3 watts of power.
2. In hibernate your computer still uses 2.3 watts of power
3. In sleep mode your computer uses 3.1 watts of power.
4. In hibernate your monitor uses about 5 watts of power.
5. Your monitor uses zero power when turned off.
6. Screen savers, at a minimum, can use 42 watts; those with 3-D graphics can use as much as 114.5 watts, according to Don McCall, a Dell product marketing manager who does power measurement studies for the PC manufacturer.
7. Turning off your computer does not use more energy than just leaving it on. The amount of energy used to turn your computer on is much less that the amount you would use if you just left it on.
8. You will not wear out your on/off button by turning your computer off at night. That used to be true, but technology has advance way beyond that now.

So now that you know the facts, you can make an educated decision on what to do with your computer to preserve energy.
