You can configure your server to use less power.

If your server is under Linux, as all my systems , you can use powertop to learn how to optimize it. Look at it's FAQ.

Between optimized and unoptimized configurations the processor in my desktop computer (an old penium IV now switched off 'cause changed by a laptop that consumes 4 times less, ie 80W to 20W) goes from 75°C to 55°C (167°F to 131°F) which does makes a difference in summer on living room temperature : 2-3°C (4-7°F).

You can also remove/unplug unused peripheral. You can configure the hard drives to shut off when unused (caution that they don't start&stop hundred times per day, some disks support only a relatively "small" number of starting).

Denis.

Radioactive wastes saved by 3kWc photo-voltaic solar panels :
  • Long life (>100,000 years) : 2.85 g/yr (0.9 mg/kWh)
  • Short life (<300 years) : 31.7 g/yr (10.0 mg/kWh)
Based upon "official" French figures...
