Green Computing – Business migration to Data Centers and the Cloud

>With the cloud computing scenario, time and power savings mean everything, in these huge scales, running hardly used servers is effectively throwing money away as well as annoying the environmentalists. In this scenario resource scheduling becomes amazingly effective. so we go back to our 5:30pm shutdown, but on this occassion the technology hosting the Virtual infrastructure kicks in, instead of sitting there half used, it will begin to migrate VM’s that no longer require resources to the same host, so although as a whole they may be using quite a lot of resource, it will enable hosts to be powered down and be sat in a ‘power saving’ state awaiting resources requirements to increase and as such power up from their slumber. Again, getting to the scale of this, you could effectively save power on as an example, 100 hosts – these hosts being the beefiest and most cutting edge servers available, are going to have requirements for a large amount of power, effectively turning these off when not used, is a god send to the idea of cloud computing. Why leave the light on in the attic if you have no intention of going there?

So that is effectively how these datacentres work from a green perspective, but from the company utilising this infrastructure, what do they save?

  • Downsize or offset office space.
  • Downsize onsite infrastructure requirements.
  • Expand the ability for users to work remotely (or globally dependent on your requirements)
  • Support the mobile workforce.
  • Reduce consumables use (printing, ink, paper, file storage costs).
  • Reduce hardware (desktop computers/server systems/UPS’s/cabling)

Congress and Light Bulb Regulation | The Energy Collective

See on Scoop.itGreen & Sustainable News

Light bulbs, as you may recall, have become a perennial excuse for certain federal legislators to whip up the conservative base, by railing again new federal energy efficiency standards.

Duane Tilden‘s insight:

Relamping projects have been an easy way to score energy efficiency gains in buildings since the 1990’s.  Inefficient incandescent light bulbs have given way to fluorescent tubes, compact fluorescent and now LED technology.

Within these stages of development each form of lighting have seen their own evolution.  The driving forces for these increases in lighting efficiency are economic starting back with the 1970’s energy crunch.

Taken from a blog on CFL development & history:

“In 1973-74 the oil crisis took place and lamp companies needed to reduce wattage in their linear (tube) lamps to compensate. Many people had four bulb fixtures and were removing two bulbs, to save energy, therefore dropping sales by half. This forced lamp companies to create energy efficient solution.

Ed worked on creating lamp with reduced wattage by adding krypton and a conductive tin coating inside. This helped lower the wattage from 40 to 35 watts but he wanted to get down to 30 watts. He continued to work and finally the wattage went from 35 to 34 and eventually 32 watts!”

Plastic Packaging Design Threatens New EU Recycling Targets

The new challenge should be that recyclability becomes a requirement fully equal to the other performance criteria. This will help to divert substantial quantities of plastics away from landfill and

Duane Tilden‘s insight:

Plastic packaging recycling does not begin with collection but design. Packaging design today is focused mainly on maximizing performance. Careless design often leads to incomplete emptying of a package and what about different combinations of polymers/materials which are incompatible for an efficient recycling process?

Plastics Recyclers Europe believe that the introduction of an EU classification system will assist designers in evaluating their creations from a recyclability point of view, in the addition it will help them in choosing the best options to improve their class.

Plastics Recyclers Europe would like to invite all interested parties to join Recy Class™ and increase plastics recycling across Europe.
