SIMON SNOWDEN, OIL VULNERABILITY AUDITING


‘Here in the west we each have the equivalent of 120 slaves at our beck and call thanks to the recent abundance of cheap energy. That amounts to more than some of the emperors of Rome...’

So says Simon Snowden illustrating at his recent seminar on Oil Vulnerability Auditing organised by the Midleton Transition Town group the folly of the way we currently take energy for granted. Simon, head of the Oil Depletion Impact Group in the University of Liverpool Management School, specialises in auditing the vulnerabilities of individual businesses to changing oil prices, drilling down into supply chains and operating systems to unearth costly sensitivities.

The phenomenon of ‘Peak Oil’ – the point at which the production of oil worldwide reaches its maximum possible output - is well accepted to be imminent, if not already actually passed. Data from oil exporting nations (Saudi Arabia and Russia being the big two) appears to indicate that their production is declining while their own consumption is increasing. At the same time, China's thirst for oil is increasing rapidly and they are moving to secure their own supplies for the future. In October this year the Financial Times chose to feature a front page article warning readers that the subsequent drop in production is likely to be in the order of 6-9% per year, rather than the 3% figure previously assumed.

This reality paints a chilling picture. Should we be worried? Yes. Should we be so worried that we pull the blankets over our heads and stick our fingers in our ears? No, but Simon’s message was that there is no point in waiting for others to solve the problem for us, that adaptation and sensible reasoning can mitigate the effects for business and even give them a competitive edge.

Interestingly, cultivation is a particularly sensitive sector, being intensely dependent on not only liquid fuels, but also sprays (derived almost exclusively from petrochemicals) and fertiliser (also highly dependent on oil prices). This is a particular worry from a farming point of view if it becomes uneconomical (or not feasible due to volatile oil prices) for farmers to grow anything and food production could be under serious threat.

The individual solutions to these problems may depend on where we are in future. Rather than striving for the ‘silver bullet’ approach of the recent past wherein one solution is deemed universally appropriate, different solutions will suit different areas. Simon used the recent example of post-tsunami Myanmar (Burma) where aid workers eventually arrived expecting to find devastated villages. Instead, they found that many of the communities had already rebuilt or had begun rebuilding programmes independently of central government. This kind of community resilience (which is rare in the current climate) is what we should be seeking to build.

Dumb eco-questions you were afraid to ask

Thanks to the Friends of the Irish Environment website, I found this brilliant article on NewScientist.com. It's a long article so I haven't copied the whole text here, but it poses and answers a multitude of tricky eco-questions, many of which I'm grateful to have an answer to at last!

Dumb eco-questions you were afraid to ask
http://www.newscientist.com/article/mg20026821.300

Here are the questions:

If I switch the light on and off every time I enter and leave a room, does this use more energy than leaving it on all evening?

How clean does the pizza box have to be for it to be recyclable? Likewise cans and bottles

Are laminated juice cartons recyclable?

What's the most fuel-efficient way to drive?
Is it worth recycling when stuff gets shipped to China and back in the process? Given the carbon footprint of all that, maybe we should just let the stuff rot

Can I save the planet by staying slim?

What's worse, the CO2 put out by a gas-fuelled car or the environmental effects of hybrid-car batteries?

What is recycled organic waste used for?

If I offset my flights, can I fly as much as I want?

If I'm stuck in a stop-start traffic jam, do I use more petrol turning my car on and off repeatedly or leaving it running?

Can I put window envelopes in the paper recycling?

How long does it take for a micro-windmill to pay for itself?

Is it better to buy an eco-friendly car, with all the energy that is needed to produce it, or just run my old one into the ground?

What's the best way to charge my laptop - little and often or let the battery run down completely?

Will washing my clothes at 30 °C really get them clean?

Why can't the machines in my gym be used to generate electricity?

Does switching from bus to bike really have any effect? After all, cycling isn't completely carbon neutral because I've got to eat to fuel my legs

Is a full commercial plane more fuel-efficient over long distances than a car?

If I turn my appliances off but don't unplug them will they still use up some electricity?

Does it really take more energy to recycle an aluminium can than to make a new one?

What is the single most effective thing I can do for the environment?

How environmentally damaging is barbecuing?

When and how is the most energy-efficient way to defrost my fridge-freezer, and is a self-defrosting fridge more eco-friendly?
What does the circling-arrows logo on European packaging mean?

What's greener, paper/cardboard or plastic packaging?
