Global Energy Consumption Per Capita ¦ 1965-2009
The following graph shows global energy consumption per capita per year for the primary energy sources (Oil, Coal, Natural Gas, Nuclear, Hydro and Renewables) from 1965 to 2009.
1. – The units are in Barrels of Oil Equivalent (BOE).
2. – ‘Renewables’ includes Solar Photovoltaic, Wind, Geothermal power generation and Ethanol.
3. – I have somewhat generously assumed that renewables are operating at maximum capacity 24 hours a day, 365 days a year.
4. – I cannot lay my hands on accurate data for Biomass. However I have taken start and end points from the orange bar in the IEA graph* and extrapolated backwards assuming its growth is a constant. If anyone has an reliable source of data for Biomass, I would be very grateful. Likewise for Solar Thermal and Geothermal heating.
5. – The graph does not show Energy Returned On Energy Invested (EROEI). Perhaps I will investigate whether it is possible to source data for this.
Edit: I’ve been looking at a similar graph prepared by The World Bank. I cannot understand why they have the anomalous huge leap from 1989 to 1990. Unless the world population took a huge nosedive around that time I can only assume they’ve made an error. Can anyone clarify?
28/02/2011 Update: Correspondence with the World Bank confirms an oversight on their part: “The problem is with exclusion of the former Soviet Union countries in calculating the aggregates. Although, we have gap-filled for those countries, the gap-filled data has been removed and aggregates have been over written. We will fix this in the database and remove the data pre-1990 to avoid this inadvertent inconsistency.”
