Even if Linode went out of their way to make sure that they offset their energy footprint (they would have to get their DC's to use green energy or maybe pay to get some green energy made that exceed the energy they use), it would still not matter.
Data centers use less than 2 % of the worlds energy according to
http://www.koomey.com/post/8323374335Of that, a part goes to cooling, and another part goes to lights, heating and other standard things in a DC. And finally, there is the power that actually goes to the servers.
Of this, the datacenter control the first 2 leaving Linode to the last part. Except if they want to switch DCs. They did in fact switch from FMT1 to FMT2. Not sure if that changed anything in the power usage or where the power come from in Fremont.
The part Linode effectively can control is what hardware they use and how much power that consumes. And as stated before, it makes sense for them to look at those numbers.
For example, going from Intel Xeon L5520 (
http://ark.intel.com/products/40201/Int ... -Intel-QPI) with a power consumption of 0.75 V - 1.35 V to Intel Xeon E5-2680 v2 (
http://ark.intel.com/products/75277/Int ... e-2_80-GHz) at 0.65 V to 1.3 V saves a tiny bit of power.
And manufacturers generally do have focus on reducing power usage, so I'm sure other components have gone down in power usage as well. Maybe most note-worthy the switch from SAS 15K RPM to SSD since the SSD doesn't contain any moving parts.
With that said, we haven't taken into account the resources needed to create all those things. And that's where it may be more effective to fix things in China first. If they get fixed in China, we'll save a huge amount of energy.
If we get more people to use public transport rather than driving a car alone on the highway, we'd save a huge amount of energy as well.
But doing more than already is being done (because it makes sense financially) in this area would be a waste of time compared to other areas where the effect would be bigger.
With that being said, I do understand the problems associated with the climate, and I do not say we should stop research in this area. But we should focus on the areas that matter.
