I have been writing perl along with some other languages, and I have been thinking about setting up a server (so that I can play with different server OS's and settings without messing anything up on our home network). My parents think that it will cost to much in power. I was just wondering if anyone knows about how much it is per day to run a computer without a monitor.
Well I saw a variety of figures given after doing a couple of Google searches, ranging from $35-150 per year, and this page:

Which had the best information. This depends on the type of computer, is it a Pentium 90 (which I doubt if you are HS intern ;-)) or is it a dualie-Xeon 1 Ghz (which I also doubt for the same reason ;-))? It also very much depends on where you live, I am assuming the states? I would check the power supply rating and ask your parent's for the cost per kilowatt/hour on their electrical bill, then you should be able to figure what your usage would be. The above link provides a computer+monitor, but it also provides a 19" television, it is probably reasonable to subtract teh TV from the computer+monitor to get just the computer since the monitor is definitely the heft of the load and likely similar to a TV.
Also remind your parents that this is an educational thing, it isn't like you are going to be playing computer games on it (unless you are setting up a quake server in which case that doesn't count ;-)) and that the benefits of learning are actually an investment for a relatively small marginal cost.
Most of the figures I saw on the web were also for 24/7 usage, which while it is pain in the rear there is no real need to leave it running constantly if it is just a box to tinker with.
Good luck, you have stumbled on to probably the best way to learn about computers, aka breaking them (at least the OS)....
