The Global Oil Supply: Implications for Biodiversity?

The link between the global oil supply and biodiversity is not directly causal; rather, the two are elements of a broader and more integrated picture. Of the energy used by humans on Earth, crude oil represents the lion’s share (33%), followed closely by coal (30%), with gas in third place at 24%. Traversing the gamut of energy sources, we find nuclear energy (4%) and hydro-power (7%), with renewable energy (wind and solar) entering the final furlong at just above 2% of total energy use, meaning that around 88% of our energy is furnished by the fossil fuels. 100 years ago, oil could be produced at an EROEI of 100, while this is now nearer to 17 as a global average, and falling, as unconventional oil sources increasingly make up for the decline in conventional production. So it’s becoming increasingly harder to maintain the oil flow into global civilization.
The Global Oil Supply.
We produce around 30 billion barrels of oil every year, which is absolutely staggering, and depending on exactly what you count as oil, this works out to 84 million barrels a day, or about 1,000 barrels every second. The major producers are Saudi Arabia and Russia, who between them produce around one quarter of the world’s oil supply….click on the above link to read the rest of the article…
