A domestic user running a single computer can make a valuable contribution to the environment by saving over *650 pounds of CO2 per year and approximately *$30-50 in electricity per year by using the ecobutton™ regularly. There are an estimated 60 million home PCs in the USA so collectively, through nationwide power saving routines, it could be possible to stop 8.4 million tons of CO2 from passing into the atmosphere through computers otherwise being left running idle during short breaks. Remember, this only includes estimates for the times when you take a break, many computers are left running over night and in these cases, the wasted CO2 and electricity costs are much higher.

And because the ecobutton™ stays illuminated even during ecomode, this can also provide a useful reminder that all unnecessary computers, lighting, heating and air conditioning etc... should be be switched off when not in use.

Notes

INPUT figure B 'Average Watts per computer' will depend on the type of computer you have and will vary depending on the type of work you do on it. Some computers use more power than others. Most desktop computers fall into the range of 60-300 Watts. Laptops are less.

INPUT figure D 'Watts rating per monitor' - the default figure assumes a 17'' LCD monitor. CRT monitors use more.
For more information on your computer and monitor watts rating check your equipment for any information labels or check your machine's documentation.

INPUT figure E 'Average cost per KW hour of electricity' - the default figure assumes an average. Check your electricity bill or with your supplier to get an exact figure for the charges you pay.
