Ja, daarop gezocht, kom ik mijzelf tegen, over Google Eemshaven en de “indrukwekkende koel- en noodstroomvoorzieningen voor de opgestelde servers”:

Wat dat aangaat, ik lees dat internet helemaal niet zo’n goed idee was.

Alsmaar toenemende rekenkracht, dan wel capaciteit:

Gaat gepaard met een alsmaar toenemend energieverbruik:

The ever-increasing and largescale deployments of Hadoop clusters bring in their wake huge energy costs.

Kon je destijds al theezetten op de stroom voor twee internet-zoekopdrachten, nu gaan ze nog even verder:

The Cloud Begins With Coal

Big data, big networks, big infrastructure, and big power, an Overview Of The Electricity Used By The Global Digital Ecosystem

EXECUTIVE SUMMARY

The information economy is a blue-whale economy with its energy uses mostly out of sight. Based on a mid-range estimate, the world’s Information-Communications-Technologies (ICT) ecosystem uses about 1,500 TWh of electricity annually, equal to all the electric generation of Japan and Germany combined – as much electricity as was used for global illumination in 1985. The ICT ecosystem now approaches 10% of world electricity generation. Or in other energy terms – the zettabyte era already uses about 50% more energy than global aviation.

Reduced to personal terms, although charging up a single tablet or smart phone requires a negligible amount of electricity, using either to watch an hour of video weekly consumes annually more electricity in the remote networks than two new refrigerators use in a year.1 And as the world continues to electrify, migrating towards one refrigerator per household, it also evolves towards several smartphones and equivalent per person.

Noot 1:

1 New refrigerator 350 kWh per EPA Energy Star; ~700 kWh/yr weekly streaming HD from [network operations] + [network embodied energy] + [tablet embodied energy]; note, ignores data centers & end-use tablet charging: ~ 300 kWh/yr wireless network operations from HD video 2.8 GB/hr per Netflix, network energy ~2 kWh/GB. Note energy use varies w location (type/age equipment), system utilization (see Auer et al, “How Much Energy is Needed to Run a Wireless Network?” June 2012). Network energy ranges from 19 kWh/GB The Mobile Economy, 2013, ATKearney, to ~2 kWh/GB per CEET, The Power of Wireless Cloud, April 2013. Annualized embodied/manufacturing energy to produce tablet (details in this report) ~100 kWh/yr per tablet, and cell network operating energy equals annualized embodied energy of network equipment used for 5 years. Refrigerator embodied energy adds 5 - 10% to lifecycle energy use of refrigerator.

Hoe verhouden de plannen voor P2P cloud storage van bijv Storj en MaidSafe zich met energiegebruik:

Safecoin-farming is cheaper and more efficient than the blockchain, because of the energy-hungry “proof of work”. It’s energy usage is not related to bitcoin energy usage, which is designed to be high. Safecoin doesn’t waste energy like bitcoin do. Energy is used to store data.

MaidSafe komt dichter en dichter bij een heus werkend netwerk en dus zitten ze zich in hun forum al te beraden op een geschikte keuze van hardware voor een ‘Safecoin-farming-rig’:

What is the best farming hardware?

At this stage of development no conclusions can be drawn, although some are looking to small energy efficient single board computers such as a Raspberry PI or Odroid’s. As MaidSafe progress through their development roadmap and implement test safecoin, the most efficient farming rigs will become clearer.

Dat, zeggen ze daar, zou dus heel goed kunnen met een een of ander dwergcomputertje, al moet in dit specifieke geval nog aan ARM-ondersteuning voor het Safenetwork gewerkt worden:
