Indian Coal Reserves

[edit]

The values published by the Coal Ministry of India:

The value puts indian reserves at 301564 Million Tonnes

Orphaned references in Coal by country

[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Coal by country's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "EIA":

  • From World energy consumption: "Consumption by fuel, 1965–2008". Statistical Review of World Energy 2009. BP. 8 June 2009. Archived from the original (XLS) on 26 July 2013. Retrieved 24 October 2009.
  • From Energy in the United States: "World Consumption of Primary Energy by Energy Type and Selected Country Groups , 1980-2004" (XLS). Energy Information Administration. July 31, 2006. Retrieved 2007-01-20.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 21:38, 19 April 2016 (UTC)[reply]

I cannot see how BGR made the calculation

[edit]

@Eddie891: Thanks for updates - although the sort still seems wrong on my Chromebook (e.g. Spain comes top for anthracite).

Have added definition but still cannot completely understand it. I see BP have got the info from BGR but (not being a German speaker) I cannot see how BGR have calculated the reserves. On their English page at https://www.bgr.bund.de/EN/Themen/GeoGrundlagen/geogrundlagen_node_en.html they explain geological methods but not the economics methodology. For example if I understand the figure for Germany right they are implying that Germany would burn over 1000 Mt of lignite a year (36 thousand million tonnes reserves but coal phase out finishes 2038) - but that cannot be right? Am I miscalculating or misunderstanding something? Perhaps they are implying the price will go down as each power station shuts therefore reserves will go down?

Chidgk1, Agreed, something is still wonky with the formatting. I'll look into it, must be with the nasty templates.
I'm a little confused about what you are asking about the reserves. By reserves it means amount of coal in the ground-- It's not how much coal the government has in a reserve like how they hold gold reserves; just how much coal is in the ground of the country that could be theoretically extracted. So when a country has large coal reserves it's in the same way they might have mineral wealth by having the potential to extract it by mining their land. Does that clear things up? Eddie891 Talk Work 18:30, 22 May 2020 (UTC)[reply]
Eddie891 Thanks for fixing sorts. I have linked to proven reserves which says "Price changes therefore can have a large impact on the classification of proven reserves". But I cannot understand how BGR estimated the price of lignite, as it is only transported a few hundred metres from the mine to the power plant. So as is not traded across Germany how do they estimate the price and thus the size of the German lignite reserve? And for other countries what prices did they use to estimate their reserves?

Factual accuracy of lignite reserves

[edit]

I don't doubt the geological expertise of BGR to calculate RESOURCES, But as RESERVES depend on the price I dispute the lignite reserve figures here. Because I cannot find anything on the BGR website to say what lignite prices (and carbon prices in the case of Germany) they used in their calculations.Chidgk1 (talk) 11:50, 19 July 2020 (UTC)[reply]

Reserves are generally defined as the amount of resources that are economically exploitable with current technology. When there is a international market, then this generally depends on the price. But an international market is not needed to estimate the economic viability of resources. For example, extraction of lignite can simply be dependent on the economics of power production from local power plants if the lignite cannot be easily transported. --Ita140188 (talk) 10:59, 20 July 2020 (UTC)[reply]
What you say is true. But as we have no idea where BGR got their lignite prices from they might just have unreliably guessed them. Chidgk1 (talk) 11:52, 20 July 2020 (UTC)[reply]
It's not our job to speculate on the reliability of specific statements in sources that are overall considered reliable. If there are other sources that doubt those claims, then we should discuss them too. --Ita140188 (talk) 13:09, 20 July 2020 (UTC)[reply]

Factual accuracy of Anthracite & bituminous reserves

[edit]

As the cost of capital has increased since 2019 (see https://au.finance.yahoo.com/news/stuck-coal-pits-world-needs-040000545.html) I dispute the accuracy of the reserve figures listed here. Chidgk1 (talk) 11:55, 19 July 2020 (UTC)[reply]

Let's just report what reliable sources found. We should not engage in speculation or original research. --Ita140188 (talk) 11:02, 20 July 2020 (UTC)[reply]
I agree with you that BGR is a very reliable source for geology. But I dispute it is a reliable source for economics. Chidgk1 (talk) 11:49, 20 July 2020 (UTC)[reply]
See my comment above. --Ita140188 (talk) 13:10, 20 July 2020 (UTC)[reply]
