$this->bbcode_second_pass_quote('', 'G')lobal oil production's Energy Return on Energy Invested (EROI) is declining as it becomes more expensive to extract oil from the Earth. This means that for each unit of energy invested in oil extraction, less energy is returned. This trend is particularly noticeable in unconventional oil sources like shale oil and oil sands, where EROI can be significantly lower than conventional oil
This has been the trend ever since the major fields peaked back last century but was never an issue until the 2000's. It pushed prices up and up until 2008, the all time high in oil prices, for which no explanation was given other than "Speculators". Every year now more and more of the oil produced must be diverted to the sole business of oil extraction. Which leaves less and less to actually power the economies of the world. It's a dog chasing it's tail scenario. Discussions of the amount of oil extracted are meaningless without the EROEI data included. It would be like me claiming my car has a range of 1000km without stating that I needed to fill it up once along the way. But the reality of EROEI has been effectively expunged from nearly all discussion on the subject of oil in the media.
This should come as no surprise, governments, who have known all along about the ultimate consequences of PeakOil to their economies were totally silent on the subject back in the 2000's. They couldn't respond because that would embroil them in the hard science and they would have been forced to admit it was going to be an unmitigated disaster for life as we know it in the decades to come. So behind the scenes they formulated the climate debate and the alternate energy/transport puppet show to distract the public and continued with business as usual. I can't blame them. If I was in power I'd want an easy life too. See out my tenure, collect my pension and kickback appointments and retire to a gated estate somewhere far away. Even the petro geologists who initially blew the whistle in the late 1990's only did so after they had retired and were secure. Only when they had nothing to lose by telling the truth. Unfortunately for the average man in the street the PeakOil debate was derailed and effectively hushed up, they went on about their lives as though nothing was happening, relying on government and the media to herd them in the right direction rather than thinking for themselves about the future. How many millions of people are living in cars and campers and hovels tonight simply because they thought tomorrow would be much like today? But then the rug was pulled out, "Sorry we don't need your services any longer, please clear out your desk and hand in your mobile phone."
Here is a good primer on the subject.
$this->bbcode_second_pass_quote('', '.')..extraction of 50 units of energy in oil (as in historic oil and gas fields) may require one unit of energy, for an EROEI of 50 to 1. But over time, as oil extraction requires increasing effort, oil’s EROEI might fall to 30 to 1, then 15 to 1. Declining EROI is precisely what characterizes the current state of fossil hydrocarbon extraction, as the graphic shows.
The implications are staggering. A declining EROEI reveals that extraction of energy will be increasingly expensive and eventually, cost-prohibitive. Hydrocarbons will still be in the ground, but the costs of their extraction will continue to climb. This also means that, barring the development of some new type of energy source, society will have to adapt to a much lower energy future. And it suggests that the monetary costs of extraction will erode GDP growth and eventually cap economic expansion.
In 2005, just a few years before the rising price of oil triggered the 2008 economic crisis, the U.S. Department of Energy commissioned a report from the think tank SAIC titled “Peaking of World Oil Production: Impacts, Mitigation and Risk Management.” It’s clear from interviews that the authors were shocked by the implications of soon-to-arrive global Peak Oil, which they termed “an unprecedented risk management problem.” Analyzing the supply and demand side of the oil scarcity challenge, they concluded that at least a decade, and more likely two, would be needed to prepare for Peak Oil and prevent social and economic upheaval.
The report garnered a great deal of attention at the time, as did other warnings of energy limits. But the subsequent “shale revolution” changed everything. Instead of being recognized as a last domain of exploration and recovery, the media framed shale and fracking as an energy elixir. The intervening years have not produced the preparatory planning that Hirsch warned should occur...
Social and economic upheaval? Look out your front door.
