[plug] Small changes to reduce Linux energy consumption

[Harry McNally]

Hello

This may be old news but the IEEE article is a good summary:

https://spectrum.ieee.org/data-center-energy-consumption

Their are caveats on the energy savings that can be achieved. But the last 
paragraph caught my attention:

Karsten said:

“When I grew up in computer science in the 90s, everybody was concerned about 
efficiency. Because computers were small, they just had a small amount of 
memory. They were slow, so you had to worry about every cycle and every byte,” 
he says. “Somehow in the last 20 years, this has gotten lost. Everybody’s 
completely gung-ho about performance without any regard for efficiency or 
resource consumption. I think it’s time to pivot, where we can find ways to 
make things a little more efficient.”

All the best
