This series of posts will be co-authored by phoenix, who is an Engineer heavily involved in the energy sector. It will be based on a submission we made recently to the Australian Government.
INTRODUCTION
Energy is a gateway resource.
Given abundant energy, minerals can be refined from seawater if necessary. But in the absence of energy even the richest mineral deposits are inaccessible.
Similarly, given sufficient energy, a valuable energy resource such as oil can be made synthetically from virtually any organic input. In theory (given the right infrastructure and energy production) the production rate of synthetic oil would be limited only by the availability of sufficient energy.
In this series of posts we will attempt to do 7 things:
- Discuss Energy Return on Energy Invested (EROEI). Show that a net-zero EROEI for a resource does not necessarily mean that the energy resource has no utility - it simply means that the energy resource has become an energy carrier, not an energy source. The burden of energy production must be moved to a different energy source. If reduced energy returns exist in our future (as they clearly do – this is happening already) then an infrastructure for this alternate energy source (or sources) must logically be built before the energy available from fossil fuels approaches zero.
- Discuss the lifespan of Australia’s endowment of fossil fuel (FF).
- Present an order-of magnitude estimate for the amount of time necessary to build an alternate energy infrastructure.
- Show that the lifespan of Australia’s current FF energy endowment is likely to be less than the time required to design and build an alternate energy infrastructure.
- Show that the energy required to build the infrastructure is likely to be a substantial fraction of all the energy that we have available, leading to an inevitable impact on GDP and living standards.
- Examine the same issues from a US/International perspective.
- Discuss solutions.

The IEA WEO 2008: Long term prospects for coal production

The International Energy Agency expects coal production to nearly double by 2030 in their World Energy Outlook 2008 if no large scale governmental intervention occurs. In this post, I analyse the likelihood of this happening from the perspective of available coal reserves.
My conclusions are that if we look at a global level, taking coal reserve data at face value, the global IEA reference scenario for coal production to 2030 is possible. However, when focusing on China, the country that now produces 41% of all coal, the scenario is unlikely to occur because China possesses insufficient coal reserves to sustain production to 2030 at the level expected by the IEA. Only in a highly optimistic case, if China's coal reserves are more than double those currently known, will China be able to sustain coal production as expected in the IEA reference scenario.
Based on available coal reserve data and scenarios (EWG 2007; Tao and Li 2007), it is much more likely that China will reach a plateau in coal production somewhere between 2015 and 2025. The implications of this are significant, because it will be extremely difficult, if not impossible, to substitute other energy sources for coal on the vast scale needed for Chinese growth. The quality of reserve data is poor, however. Better reserve data is needed, particularly for China, to have certainty with respect to these findings.
In a follow up post, I will take a look at the short term prospects to 2015 for coal production, imports, exports, and prices in relation to the World Energy Outlook 2008.

This is the last of the posts that deal with the content of the ASPO Conference last week in Houston. I will have my usual personal closing review tomorrow. As I hope you will gather, it was full of information and somewhat intense. And that did not include talking to folk in the breaks, which expanded a lot on what was being said in the papers. So if you want to think of this as the first commercial for next years meeting (which will be in California) then you’re right again. And just to remind you, the earlier posts were a report on the Workshop day, the first morning report, the rest of Thursday, and then Friday morning. A quick thanks to all, and it was more fun than I had even hoped to meet so many of the TOD folk, as well as so many others – thank you all, and of course, a much bigger thank you to the organizers for putting this on. The result, gentle folk, was well worth the effort.
We rejoin the meeting just as we sat down to lunch, and a talk by Houston Mayor Bill White who has the enviable distinction of having Matt Simmons as the Treasurer of his Campaign Committee. He acknowledged Matt as a prophet (with all that usually brings). He sees the current situation as one that comes down to a race between depletion and technology. It is not possible to give a political speech and create more oil fields. It is not possible by giving a political speech to create a hydrogen economy either immediately or in the practical future. It is not possible by giving a political speech to over-ride the laws of physics.
