Copenhagen Climate Council Promotes GNU/Linux on Thin Clients

The London Summit must agree that investment in low-emissions technology and infrastructure must be integral to government recovery packages in order to create jobs, foster innovation, and achieve energy security through the 21st century. Governments should individually implement and document their efforts in this regard.


see Their letter to G20 leaders.

If that is not a promotion of GNU/Linux on thin clients, I do not know what would be more clear. Energy produced by fossil fuels runs many PCs. If we replace the PCs with terminal servers and thin clients we can save a lot of power consumption:

  • typical thick client consumes about 100 watts apart from the monitor, keyboard and mouse
  • typical thin client can be 20 watts or less
  • the difference is about 80 watts saved per conversion to thin client, perhaps 75 watts because we need a terminal server which runs a bunch of thin clients
  • 75 watts saved times 1000 million PCs is 75 gigawatts

We can also save on production/waste costs because thin clients can last several times longer than most PCs.

On top of that we get ease of management and better performance with shared memory and file caching, no downside except video, which is why we can still have a few thick clients or televisions.

My Mission

My observations and opinions about IT are based on 40 years of use in science and technology and lately, in education. I like IT that is fast, cost-effective and reliable. I do not care whether my solution is the same as yours. I like to think for myself.

My first use of GNU/Linux in 2001 was so remarkably better than what I had been using, I feel it is important work to share GNU/Linux with the world. I have been blessed by working in schools where students and school systems have benefited by good, modular software easily installed in most systems.

I have shown GNU/Linux to thousands of students and hundreds of teachers over the years and will continue in some way doing that until I die in spite of the opposition.
