This site is running on an energy efficient / low power web server, consuming 25 Watts. I have built the web server using off the shelf hardware and software.

The hardware is based on VIA12000EG motherboard, and the software is based on Linux (Ubuntu) and Apache HTTP Server. 

The following hardware is used :

 The following software is used :

  • Joomla 1.5 as content management system
  • Mysql
  • Apache Tomcat running on JDK 1.6
  • Apache HTTP Server, version 2.2.x
  • Ubuntu Linux, currently Ubuntu8.04LTS (it took only 90 minutes to upgrade from 7.04 va 7.10 to 8.04, using do-release-upgrade)

 Measured energy consumption

I have measured the energy consumption for 10 months, and it is fluctuating between 25 and 27 Watt.

So I think it is a nice energy efficient machine, and deserves the term low power web server.


I have recently built a powerful web server, using an Intel Quad Core CPU, and measured the energy consumption, and was quite suprised at the fairly low energy consumption of about 100 Watt.
