+**Solar Protocol** is a project that connects solar-powered [[WWW]] servers from around the globe, redirecting traffic to a server that has solar power available (i.e. the part of the globe where the sun is shining).
-A problem with Solar Protocol is that it neglects the energy requirements of
-the [[Internet]] infrastructure that lies between the solar-powered servers.
-However, we can be fairly sure that routing a packet across the world takes
-much more energy than routing it across a country.
+A problem with Solar Protocol is that it either neglects the energy requirements of the [[Internet]] infrastructure that lies between the solar-powered servers and the users, or takes them as a constant that only depends on the amount of transferred data. However, we can be fairly sure that routing a packet across the world takes much more energy than routing it across a country.
-If the power consumption of a server is small to begin with, its "greenness"
-may very well get negated by a bad routing decision. It may very well be
-"greener" to just route a user to nearby grid-powered data center than to a
-solar-powered server on the other side of the world.
+If the power consumption of a server is small to begin with, its "greenness" may very well get negated by a bad routing decision. It may very well be "greener" to just route a user to a nearby fossil-powered data center than to a solar-powered server on the other side of the world.
-Taking the network into the equation is difficult because even academic
-estimations of the power consumption of Internet routing have varied by
-several orders of magnitude. Still, there seem to be no mentions of this
-issue on the Solar Protocol website. Given the prominence of SP in the
-media, it is highly unlikely that the people involved have not heard about
-this kind of critique.

-In 2015, it was estimated in a meta-analysis by Aslan&al. that moving a
-gigabyte across a national cable network took 0.06 kWh. This is the same
-figure as for running a 10-watt server for 6 hours. Even if the current
-figures are much lower, they cannot be ignored as irrelevant if the server
-network actually serves data instead of mostly remaining idle.
