April 20th marked the one year anniversary of the largest accidental oil spill into an ocean that released 4.9 million barrels of oil into the Gulf of Mexico. Not long after the accident, I wrote a post on this website about the geopolitics of oil supply referencing Michael Bradshaw’s article on the Geopolitics of Global Energy Security. The stats Bradshaw provides on both the major suppliers of oil, and the countries with the largest reserves, still intrigues me.
The Society of Biology, on the one year anniversary, released a briefing on the spill which provided numerous links to news articles and official sites. The environmental impacts remain uncertain, with some people saying that the impact is less than anticipated, while others say that the full impacts will only be felt in the long-term.
The answer to my question of last year– will this disaster lead to a push for renewable energies, or lead to the exploration and exploitation of oil in more remote areas of the globe- remains largely unanswered.

In a paper in The Geographical Journal, Michael Bradshaw describes two pressures facing energy policy.
First, there is the need to guarantee a reliable and affordable supply of energy. Energy security can be threatened by domestic disputes (e.g. in France, recent strike action caused the country to import large amounts of electricity) and international tensions (which led Russia to restrict gas exports via a pipeline to Belarus, in June 2010).
Second, the current reliance on carbon-based fossil fuels (coal, oil, gas) is unsustainable. The economic and environmental costs of extracting fossil fuels, alongside the threat of climate change, means that it is increasingly difficult to match demand with carbon-based energy sources.
The Statement on Energy Policy, recently announced by the UK government, reflects these concerns. The policy envisages half the new energy capacity built in the UK between now and 2025 will come from renewable sources. Nuclear and wind power are highlighted as key areas for development.
However, as Bradshaw argues in his paper, emerging economies in the global South will cause a shift in global energy demand and production. Geographers can play a key role in informing national policies and investment, by linking changing patterns in global energy use and resource distribution, to national and local impacts.
Our dependence on energy is increasingly fragile. In the US, oil companies are drilling deeper and taking more risks in response to the demand for cheap oil. In April, a Transocean/BP oil rig in the Gulf of Mexico exploded and sank, resulting in a massive oil spill. Regardless of how the situation has been managed, it was the demand for oil that meant that the oil rig, with all its associated risks, was there in the first place. Energy supplied by fossil fuel is becoming more risky to obtain.
Meanwhile, on the Isle of Eigg, off the west coast of Scotland, residents have been urged to use household appliances less as a lack of rain has reduced the amount of electricity generated through hydro-power schemes. Energy supplies are becoming more difficult to sustain.
In Belarus recently, piped gas supplies from Russia were reduced in response to a disagreement over payment for gas and the use of transit pipelines. Energy security is therefore not just a case of the geographical distribution of supply and demand, but is also dependant on complex social processes and international relations.
Michael Bradshaw deals with these themes in an article in Geography Compass, published in 2009. Bradshaw illustrates the multidimensional nature of energy security. For example, climate change policy is driving a reduction in reliance on carbon-based fossil fuels. At the same time, China and India’s rapidly developing economies are increasing their demand for energy, reshaping the challenges of energy security as they add their voices to the debate.
Geographers are well placed to understand the interface of the physical and political drivers of changing energy supply and demand. A key challenge remains in translating this into an understanding of energy security and the policies needed to sustain affordable and sufficient energy supplies.
