If you remember, six months ago I started looking at my energy costs at the modest home office and how I could try and reduce them and lower my monthly (expensive) electricity bill. My last quarterly bill came at the beginning of February and the next one is due soon.

Determining how much I could save s not impossible, I could just go look at the meter and work out the numbers for myself, but for companies looking to save electricity their options are somewhat limited.

There's an article here that talks about methods some companies are using to determine how much their computers and data centers are costing them.
