The chart shows the past UK government's forecasts for the oil price together with the path that the price subsequently followed. Predictions are taken from the documents at http://www.decc.gov.uk/en/content/cms/statistics/projections/projections.aspx. The year 2000 predictions turned out to be far too low, and were radically changed by 2005. These predictions were in turn radically changed in 2009. This poor record of past prediction is shared by many other organisations. This does not give any confidence in the latest price predictions. Yet the oil price has a major impact on individuals, organisations and countries, and the price of other forms of energy is closely linked. So we feel it makes sense to reduce your dependence on fossil fuels.
You can reduce your dependence on fossil fuels, and your vulnerability to future oil price instability by calculating and reducing your carbon footprint.
