Power down in South Africa continued… February 2, 2008

Here’s an excellent post from my favourite blog about energy and the crisis that faces us, The Oil Drum: Understanding the current energy crisis in South Africa, in which the authors point out that the underlying problem is exponential growth. To quote:
Yes, at this rate of growth we will double our economy. What is it we will be doubling? We will double our GDP. This means we will double what we produce. In order to double what we produce we will need to double what goes into what we produce. This includes raw materials and crucially, energy. Yes. Roughly speaking, on this growth path, in the next 11 years we are going to need to double the amount of energy we are currently consuming.
As Albert Bartlett, Professor Emeritus, Physics Department, University of Colorado, once wrote: “The greatest shortcoming of the human race is our inability to understand the exponential function”.

The CEO of the Southern African Tourism Services Association (SATSA), Michael Tatalias, attracted the ire of both Eskom, South Africa’s power utility, and FIFA, world football’s governing body, when he stated that Eskom’s rolling blackouts are threats to both tourism and the 2010 World Cup.
Predictably, the local media latched on to these statements, which I agree are rather sensationalist, and trumpeted them loudly, but failed to even mention the other half of his statement which asks what we as citizens and businesses are doing to curtail our consumption of energy.

This post is only tangentially related to travel, but it has a lot to do with sustainability, so I thought I would vent here on this blog anyway. As I sit here writing this, South Africa has entered a period of rolling blackouts. The cause is uncontested: the government failed to allow the national power utility, Eskom, to create generation capacity way back in the ’90s. After an unprecedented period of economic growth the chickens have come home to roost and the reserve margin is down to 8% so that the grid has no resilience when capacity is temporarily reduced by an outage or when demand spikes. Meanwhile the demand trendline shows unabated growth. The crisis is expected to last for another seven years, by when additional generating capacity should come online.
But what interests me are the reactions to the crisis from my fellow citizens, which only serve to show how difficult it is to change behaviour and how invested in our energy-intensive consumer-age paradigm we are. (more…)
