Do ENERGY STAR appliances run on less electricity?
ENERGY STAR appliances can significantly reduce your electric bills. The average home appliance lasts for 10 to 20 years, and an ENERGY STAR-certified appliance will use anywhere from 10 to 50 percent less energy each year than a non-energy efficient equivalent.
How much electricity does a computer use in 24 hours?
200 watts multiplied by 24 hours divided by 1000 multiplied by 365 days in the year equals 1752 kilowatt-hours (kWh). In the US, the average cost of electricity per kWh is around 13.31 cents, so 1752 multiplied by 13.31 comes to a cost of around $233 dollars to keep your computer powered on 24/7 for an entire year.

How much energy does a notebook computer use?
While they use less energy than desktops, notebook computers still burn about 20–30 watts of power. System standby and hibernate features reduce notebook power draw to 1–2 watts, so the energy savings are still very significant.
Do you use more energy with power management features activated?
3. Do computers and monitors use more energy with power management features activated due to power surges when cycling on and off? A popular myth holds that leaving lights, computers, and other appliances on uses less energy than turning them off and also makes them last longer.
How does system standby and hibernate save energy?
System standby and hibernate features reduce notebook power draw to 1–2 watts, so the energy savings are still very significant. Be sure to activate system standby and hibernate features in the AC power profile (which saves power when the notebook is plugged into the wall) — not just the DC power profile (which prolongs battery life.) 8.
