Cost associated with running a computer for one day

I saw this on Folding@Home’s website.

How much power/money is used by keeping a F@H running 24/7 on a computer?

Roughly, a CPU uses about as much power as a 60 watt light bulb. Here’s a report on computer power management from Lawrence Berkeley government labs, and there are other references on the web you can find. Although power supplies on most computers are rated at 250 watts, average usage is much lower. On average, a Pentium-type computer uses between 45-70 watts (I’ve read various different sources on this) while it is on. If the computer has no idle mode, it will use the same amount of energy whether it is running a program or not. If it is on idle, it will consume around 25 watts. So, the daily difference between off and running F@H is about 24x(45 to 70) = 1.1 to 1.7 kWh. At $0.14 per kWh ( from PG&E here in California), this works out to about $0.15 to $0.24 per day, or perhaps $6 a month. The difference between an idled computer and one running F@H would be closer to $4 a month - and if the computer was already being used 8 hours a day, it would be closer to $3 a month.

In general, lighting and climate control use a much larger share of household power than computers do. So the best bet for cutting costs and conserving energy would be to turn off lights, turn off your computer monitors (which use more power than a CPU), and turn down the heat. And keep folding :)

Facts about Bill Gates

Taken from http://evan.quuxuum.org/bgnw.html. The ones I found especially interesting:

According to the National Coalition for the Homeless, there are 760,000 homeless people in America. Bill could give each of them $42,133.53.

According to the people at Save the Children it costs $240 to sponsor one child for a year. This means that Bill could save 133,422,850 (133.42 Million) of the children. Of course, there are only 58.5 million people (adults included) in all of Ethiopia.

According to the people at Make-A-Wish, it costs between $3000 and $4000 to grant a wish to an ill child. Assuming an average of $3500 per wish, Bill could grant the wishes of 9,148,995 or 9.15 Million children.

It costs roughly $30,000 to purchase the supplies to build a 3 bedroom home for Habitat for Humanity. (Labor is donated.) Bill could donate supplies for 1,067,382 homes. Since these are 3 bedroom homes, let’s assume 4 1/2 occupants per house; Bill could house 4,803,222 people.
