Why does the Nagaur hand tools profile print 1,183 toe as both energy use and saving?

In the United Nations Industrial Development Organization (UNIDO) profile of Nagaur's hand tools, total energy use and total saving potential both print as 1,183 tonnes of oil equivalent (toe) a year, and the specific energy line reads 0.279 gigajoules (GJ) a tonne against unit ranges of 12.3 to 14.7. These do not tie, and the profile does not say why.

What the profile prints

• Energy table: furnace oil 1,200,000 litres, 1,020 toe, 86%; electricity 1.9 million kilowatt-hours (kWh), 163 toe, 14%; total 1,183 toe. These add up.
• Saving table: 'Total energy saving potential 1,183 toe/yr' and 'Total CO2 reduction potential 0.001 million tonne' (CO2 is carbon dioxide).
• Performance table: total energy consumption 1,183 toe per year, specific energy consumption 0.279 GJ/tonne, total CO2 generation 0.005 million tonne, emission intensity 1.1 t CO2/t product. Its heading reads 'Performance of Thangarh ceramic cluster', the name of another cluster.

Three checks

• Saving equals use. The text names 30% on forging furnaces, about 10% on furnace auxiliaries and about 15% on machining. Taking 30% of the 1,020 toe of oil and 15% of the 163 toe of electricity gives about 306 + 24 = 330 toe, 28% of 1,183, before the 10% line, whose base the profile does not give. So the table repeats the consumption figure. This is my reading.
• CO2 line is the sensible one. 0.001 million tonne is 1,000 t, and 30% of the oil is 360,000 litres, about 1,070 t at the 2.97 kg per litre used on the Nagaur furnace oil page linked below. The CO2 saving looks like the oil saving.
• Unit label. 1,183 toe over about 4,200 tonnes is 0.28 toe a tonne, which is close to 0.279 only if the tonnes are rounded (0.279 would imply about 4,240 tonnes). A toe label in place of GJ is one possible slip, not a full explanation. 0.279 toe is about 11.7 GJ. The unit range of 12.3 to 14.7 GJ a tonne is given alongside 0.294 to 0.351 toe a tonne, so the range itself ties.

A cluster average below every unit

At 0.279 toe a tonne the cluster average sits under the lowest unit in the stated range, 0.294. An average cannot normally do that. The profile does not explain it. My reading is that the tonnes and the energy are not on the same base, perhaps because machining units are counted in one and not the other. The Nagaur profile's performance table is headed 'Performance of Thangarh ceramic cluster', the name of another cluster's profile. My reading is that the table was adapted from that template.

What to use instead

• Litres of oil and kWh, which tie to the toe lines and to each other.
• Your own litres and tonnes forged, from invoices and dispatch slips.
• The percentage options, applied to your own furnace oil, not the 1,183 toe saving line.

The checks in numbers (my calculation)

• Use: 1,020 + 163 = 1,183 toe; oil share 1,020 / 1,183 = 86%
• Saving, two clear lines: 0.30 x 1,020 = 306 toe; 0.15 x 163 = 24 toe; total 330 toe
• CO2 on the oil line: 0.30 x 1,200,000 = 360,000 litres x 2.97 kg = 1,069 t
• Intensity: 1,183 toe / 4,200 t = 0.28 toe a tonne; 0.279 x 41.868 GJ = 11.7 GJ a tonne

Source figures are as printed. The profile gives a visit by The Energy and Resources Institute team as December 2010. 2.97 kg per litre is the furnace oil factor on the Nagaur page linked below.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your own furnace oil litres and kWh from invoices and bills are on file by month, so you do not have to lean on a cluster table that does not tie. It is not a third-party verifier and does not issue credits.
