The virtual choice

Virtualisation offers us a way to extend the life of old software. The hardware can be upgraded to the latest specification, allowing the legacy software to take advantage of increased performance. In the past applications tend to be run on their own dedicated server hardware. More applications...

Can the IT industry be green?

Cliff Saran Profile: Cliff Saran
Green IT, inefficiency, IT industry

There is no one answer. The industry relies on businesses and consumers to buy the latest hardware, software, mobile phones and gadgets. The manufacturers create demand for new products and fulfil that demand with ever-more sophisticated products. Financially, the IT industry seems like it can...

Bloatware is not green

I have mentioned previously that our reliance on Moores' Law has meant programmers no longer worry about the limitations of the target hardware. Coding used to be an art-form, squeezing the maximum performance using the tightest programming techniques. Today's coders simply link to a bloatware...

Green IT, Moore's Law

For the last few days I've been looking at the issue of green IT. It strikes me that a major contributor to the energy inefficiency of modern IT is our reliance on Moore's Law, which has progressively lowered the cost of computing power. My very first home computer had only 32 Kbytes of memory,...

More hot air

Green IT

It does amuse me that PCs expel hot air. Along with the fan for the CPU, we can now buy fans to cool the hard disc, graphics cards and the inside of the case. AMD and Intel claim their dual core processor architectures will dramatically reduce power consumption. But I fear, any gains in efficiency...

The BBC website is reporting on "Green Shift", a taskforce led by Manchester City Council to oversee the piloting of a "green PC" service in which individual machines use 98% less energy than standard PCs. The way the PC industry operates is...

Over 40 years ago Gordon Moore predicted how the integrated circuit would enable people to buy chips for the same price but double the complexity every two years. The law has more-or-less governed hardware development. It has been...

Can’t get rid of the hot air

Air-conditioning, Green IT, inefficiency

Our office has been rather hot today. Even though the aircon is on full blast, it is ineffective. Why? because the PCs on our desks and computer monitors are radiating heat. In fact, PCs have a fan to expel the hot air from inside the case straight into the office. The PC generates hot air, because...

Are you green? If not, why not.

Are you green? If not, why not. Everywhere I turn, people are turning green. Green is a vote winner; green demonstrates corporate social responsibility and in some circles, green is cool. Of course we must save the planet. But what impact will little me make. Not much unless my neighbour does,...

There’s more to green IT than energy efficiency

Replacing IT equipment with more energy efficient products is one of the ways we can do our bit to tackle global warming. However, this is not the whole story. I interviewed Gartner research director Simon Mingay last week. He is speaking next week at Gartner's ITxpo in Barcelona on the subject of...
