Seti's Carbon Footprint

I have thought a little about that, and read some previous discussions, and at least for me personally I came up with only more questions:

- Do the benefits ( both potential and realised) outweigh the costs ?
[ By potential benefits I mean the obvious, by realised I mean to the advancements in Distributed Computing advancing many areas of science that may end up helping resolve some of those costs, and as yet untapped uses for the newly advancing science]

- How much carbon would my activities be using without contributing to the science? [ In my case, probably as much or more, others would differ ]

- What about those whose electricity comes from alternate sources, such as windmills in Europe, Nuclear power elsewhere, and hydroelectric and others ? [ How does that change the formula? ]

- Can gains In medicine, Environment and science and technology be made in less costly ways, at the same or increased rate ?

All these are probably not possible to answer, except as directly pertains to our own situations. It then becomes a personal choice which may not know the benefits directly ever. In my personal experience it only makes sense that money and resources etc have to be spent to make gains.

Others' experience and choices will differ from mine.

[ So I suppose in my personal case:
- will doing nothing solve the world's problems ?
(I guess not....}
- will contributing solve the world's problems ?
( It may help some problems, directly or indirectly, in the long term, or it may not. )
- Are there better ways to contribute?
( Possibly, At least I recycle and try to conserve in other areas, A very small impact but I figure a lot of small impacts might make a big one :D ) ]

Leaving on your computer all day to analyse Seti signals increases your carbon footprint. Is this a concern? Should we be turning off our computer at every opportunity to conserve energy and reduce global warming?

Since I do leave my computers on pretty much all the time, I signed up for Green Electricity. Here in Australia, it's a Government regulated scheme that basically guarantees your power comes from renewable generation, not coal (we have no nuclear here).

I'm sure similar things exist in other countries.

On the other hand, if you're running BOINC on an office PC, consider; the PC may draw say 120W idle, and 150W on load - for an extra 30W, you get actual scientific work done, compared to it just sitting there consuming power for nothing except minefield (ok, a bit harsh, but you get the drift).

I've been reading this thread and have been wondering my self for quite some time about the power used by a computer running 24/7 and did some sums. If you go by what your PSU is rated to then you are getting a maximum value, in my case that is 18kW/h a day (750w PSU * 24 hours = 18000W). The problem in useing this figure is that firstly it assumes that the computer is drawing maximum power all the time, ie. all hard drives, cd rom drives, floppy drives, graphics cards, case fans,cpu fans running flat out 24/7 which doesnt happen. also it assumes that your PSU is the exact size for your system. i know mines is bigger than i need cos i bought one 150W bigger than recommended so that i would be able to up grade at a later date. it also doesn't take into account the power the monitor draws.

the 18kW/h a day is a big number but i know its not accurate cos i leave my computer on 24/7 and on my power bill is says i only use 9.8kW/h a day less than half the value of the computer, for my entire house and i have a wife and 2 kids. course i do have gas hot water.

Also while i'm here has anyone ever heard of a PSU that runs off 12V DC rather than having to go to AC? it shouldnt be a problem cos the biggest voltage inside the computer is 12V. is there a PSU out there that converts 12V DC into the required voltages for the computer?

Its actually a practical approach too as they save rainforest and plant trees...
