I guess that coal will be the other half of our future electricity generation.
E.ON has earmarked ?540m to build Britain's first power station fired by "clean coal" technology as growing concerns over the country's energy supplies from abroad spur efforts to boost domestic power generation.

I thought they were around about ?300m? (maybe they were on sale ..!  )
They must of gone up in price ...... 
Maybe Im thinking of gas power stations.

I find the issue of Britain's coal reserves rather confusing.
The BP Stat Review states that we have 220 million tonnes and the EIA says 243 million short tons. At a production rate of 25.1 million tonnes a year, that would mean an R/P ratio of less than 9 years.
World Coal http://www.worldcoal.com/Coal/CL_regional_report_oct04.htm claims 1500 million tons (or tonnes) which is about six times greater. I have heard dozens of claims of hundreds of years for UK coal. The Telegraph report (link) claims 200 billion.
Is anyone aware of the cause of this discrepancy and which is right?

I believe 2 key issues are:
1) The quality of the coal - a lot of the coal we burn now is imported already, because of the need to burn "clean" stuff, which a lot of uk coal apparently isn't
2) The difference between the total coal in a given field and the total that can be extracted (URR) can be an even wider gap then with oil
I dont have any references to hand, I'll see if I can dig them out.... |

It's all to do with economic and technical viability. It is true we have less than 10 years of R/P coal in today's economy and with today's technology. However if we needed a lot more coal, or if imports reduced or went up in price, or if clean coal technology made it more attractive to burn etc then the current economic and technical conditions would have changed and the R/P time would also change.
