I’m currently looking through the BP statistical review of world energy
http://www.bp.com/productlanding.do?cat ... Id=7044622A few of the figures in there confuse me and i think i’m reading them incorrectly.
Total wind production for 2009 – 160,084 Megawatts
Total Solar production for 2009 – 22,929 Megawatts
Total Geothermal production for 2009 – 10,710 Megawatts
The problem i’m trying to solve is how many Btu’s these figures calculate into – but i believe i am using wrong conversion figures.
I’m using the conversion of: 1 Megawatt = 3,410,000 Btu
So the figures are:
Wind production 2009:
545,886,440,000 BtuSolar Production 2009:
78,187,890,000 BtuGeothermal production 2009:
36,521,100,000 Btu I realise Alternatives total contribution is small – but these figures seem far too small to me.
The reason i may have it wrong is that i’m using 1 Megawhatt hour = 3,410,000 Btu and by megawatts you may not mean megawatt hour.
Should i then multiply these figures by 24 and then by 365?
This would then give a wind production of: 4,781,965,214,400,000 Btu
Which seems more in line with general concensus.
For example EIA figures from 2008. The below numbers are all in quadrillion Btu’s
Nuclear 27.159
Hydroelectric 30.735
Geothermal 1.27
Wind 2.075
Solar, Tide, Wave 0.088
Biomass and Waste 2.620
Comparing these to the 2009 figures given by BP something is clearly wrong as BP have wind as only 500 billion in 2009 – yet in 2008 the EIA have wind as over 2 quadrillion – so there has to be something wrong with the calculations i’ve made.
I was wondering if you know whether this is the case and if i’m using the wrong conversion figures?
If i look at Hydroelectric Production the figure is: 740.3 Million tonnes of oil equivalent.
And using the conversion of one tonne of oil equivalent = 40 million Btu
The total figure is:
29,612,000,000,000,000 Btu I realise that Hydro production is much more than wind, solar, etc – but not by this much – which is why i’m worried my figures are very incorrect.
Any advice you could offer on this would be greatly appreciated as i’m completely stumped.
