It looks like plans to build one of Europe’s largest wind farms on the Isle of Lewis in the Outer Hebrides, Scotland, are to be turned down.  As one would imagine, local anti-wind farm campaigners are gleeful whilst supporters of the 181 turbine scheme feel embittered.  

I have mixed feelings; on the one hand I am all for harnessing the power of wind to produce energy. We need more energy and we’re not getting enough from fossil fuels. Having visited the Western Isles a couple of years ago, I can tell you, it is one of the windiest places I know!  

However, it is also one of the most beautiful and unspoilt and a big part of me recognises that that is its charm and uniqueness and it should be preserved. Whilst there, I felt like I had entered a very special community that welcomed me with open arms but was not trying to be anything other than what it was nor pander to my whims merely because I was a tourist, like some other holiday destinations. Where else can you go these days where the locals leave everything unlocked because there is no crime? Or you can walk mile upon mile on golden sandy beaches and not see another human being? I can’t help but disagree with Angus Campbell, vice-convener or Comhairle nan Eilean Siar (quoted or BBC News website): “……….Are we to become and environmental museum? Is any development at all to be allowed in the Western Isles?”

There are other parts of Britain, like Yorkshire, Staffordshire, Northumberland and Wales, for example, where ex-open cast mining sites used to be located. Surely they, or similar habitats, can be utilised? I don’t know but what I do know is that it would be a tragedy to do anything that would change the very fabric of the Hebrides – the jewel in the crown of the British Isles.

As if proof were needed that the world is on the brink of an energy crisis, look no further than South Africa! The country is rich in gems and precious metals and some of the world’s largest gold and platinum mining companies. This week they suspended production due to a ‘national emergency’ and spate of recent power cuts, which have ground business to a halt in many areas. 

Two things come to mind: firstly, thank goodness this is 2008 and not a bygone era! Mining company owners and bosses back then would have cared less about health & safety and minors being trapped underground by a power cut than they obviously do now! Drastic though it may seem, they took the right course of action shutting everything down. Secondly, if these companies are some of the world’s largest (and one would assume, richest) in their field, why do they not join forces and lobby the Government for more action on energy issues; including infrastructure construction and maintenance? Surely, above all these days, this is the one element that is an obstacle to a country’s economic growth. 

I love this quote from Goolam Ballim, chief economist of Standard Bank Group, based in South Africa: 

“Power is like Oxygen, it’s essential for any half-modern economy.” 

Absolutely! And protecting its source should be foremost in every business owner’s mind.

It’s interesting that people assume the electricity that comes out of the mains power supply is as pure as distilled water. It isn’t. It is contaminated by all sorts of ‘nasties’ that can lead to sags, surges, brownouts, harmonics, flicker, frequency deviations, interference, interruptions, distortion as well as complete blackouts. In turn, these problems can have dire consequences. Firstly, they will shorten the life of equipment by causing wear-and-tear and they can also cause complete breakdown.  

With computer systems, these problems are magnified as equipment tends to be sensitive to fluctuations in voltage current. They can result in data corruption or loss, which for many companies may be devastating in terms of business continuity, reputation and customer service. In extreme cases, harmonics for example, has been known to cause fires.  

What can be done?  

UPS is the answer. Not only does it protect equipment from complete mains power failures, it also contains filters and conditioners that keep the voltage current to within an acceptable level and cushion against many of these problems. This can be helped with a little insight and research into which power problems are most prevalent at your site, their magnitude and frequency. This information will enable you to choose the right solution for you. Large sites may benefit from power monitoring, a service offered by specialist (like Riello UPS) to record disturbances over a specific time period.

The argument over bio fuels is raging. It centres on two key points: on the one hand bio fuels are said to be good for the environment because they produce fewer emissions than fossil fuels and so can help to reduce greenhouse gas emissions that are said to be driving climate change. On the other hand, some organisations believe that bio fuels will do more harm to the environment in the way they are produced unless strict controls are imposed.  

The Royal Society issued a report this week, which followed a 14 month enquiry at the same time as the European Union announced re-examination of its targets for bio fuels because of fears of their impact on the environment. The fear is that forests will be decimated to make way for land on which to grow bio fuel crops.  

It stands to reason that in poor communities where environmental concerns are much less of a priority than putting food on the table, the urge to clear forest to make way for valuable crops would make sense. But it is often not these communities who live on the land who make the decision; it is the Governments and big businesses around the world who will initiate the competition for agricultural land between bio fuels and the crops needed to feed the expanding world population. However you look at it, it would seem trees are doomed and that’s bad news for everyone. It is a well-known fact that curbing carbon dioxide emissions is far easier by restoring and protecting forests.

I was reading the cover story of December’s InformationAge at the weekend: Crossed Wires – Myths and Misconceptions of IT’s Energy Crisis, and I was horrified by some of the controversial views and opinions expressed therein. In my mind the article fell short of addressing the so called ‘Myths and Misconceptions’ but rather replaced them with even more perilous and unproven ones.  

Basically, it focuses on data centres and how they are wasting vast amounts of energy. There are some companies out there ripping up the rule book, apparently, in terms of cooling requirements, power protection, conversion, and ambient temperature!  

I agree that there is a pressing need to address the problem of excessive power consumption in data centres but to do it by such radical measures as fresh-air cooling, the elimination of UPS and running at temperatures from five to 50 degrees centigrade is going to create more chaos and cost far more, replacing damaged equipment and compensating for down time, in the long run than sensible energy-efficiency measures.  Fresh air cooling, for example, may introduce contamination and even humidity that has the potential to damage sensitive data centre equipment or lead to expensive wear-and-tear.  The argument raised in the article around UPS suggests that it adds to energy wastage as a result of the necessary power conversion back and forth from AC to DC. Some experts believe that data centres can be run completely on DC power to avoid this.  This is not true: firstly, today’s UPS are designed to be hugely efficient and help project the life of computer equipment through conditioning of the voltage current as well as providing essential power protection and continuity of critical systems. Running only on DC power would require unfeasible amounts of copper wiring. The argument about temperature is also flawed: computer equipment can withstand fluctuations outside of the recommended 20-24 degrees centigrade but anything that contains consumables, fans and batteries, will be severely compromised by such practices. Fans will be continually over exerted in high ambient temperatures and batteries will need replacing more frequently at anything above or below this recommendation.  

It doesn’t take much downtime to cripple a business these days. Energy efficiency and intelligent power management should go hand-in-hand with power protection not instead of. See Riello UPS for more information on power protection and energy efficiency.
