In Dehradun's pharma cluster electricity is 63% of the energy but 69% of the bill: how much carbon dioxide (CO2) does each rupee (Rs) of power, diesel and liquefied petroleum gas (LPG) carry?

In The Energy and Resources Institute's (TERI) 2015 table, power is 63% of the energy, 69% of the bill and 83% of the CO2 at today's factors. A rupee of power carries about 0.10 kg of CO2, a rupee of diesel 0.05 and a rupee of LPG 0.05 (estimate).

The printed table

• Electricity: 59.6 million kilowatt hours (kWh), 5,126 tonnes of oil equivalent (toe), Rs 387.4 million.
• Diesel (high speed diesel or light diesel oil): 1,573 kilolitres, 1,332 toe, Rs 81.8 million.
• LPG: 1,365 tonnes, 1,616 toe, Rs 88.7 million.
• Total 8,074 toe and Rs 557.9 million. The lines add up to both.

Three shares side by side

• Energy: electricity 63.5%, diesel 16.5%, LPG 20.0%.
• Bill: electricity 69.4%, diesel 14.7%, LPG 15.9%.
• CO2 at today's factors: electricity 40,230 tonnes (83.0%), diesel 4,161 tonnes (8.6%), LPG 4,068 tonnes (8.4%). Total about 48,458 tonnes, or 48,459 when each line is rounded first.

What the prices in the profile really are

The profile prints diesel at Rs 52 a litre, LPG at "Rs 65 per litre" and electricity as an "Average energy charge" of Rs 6.5 a kWh. The bill column matches units times those prices to the first decimal: 59.6 million x 6.5 = Rs 387.4 million, and 1,573,000 litres x 52 = Rs 81.8 million. For LPG, 1,365 tonnes at Rs 65 a kg is Rs 88.7 million. So the LPG price only works per kg, not per litre as printed.

Our reading: the power line is the energy charge alone, so fixed and demand charges are not in it, and a real power bill would be higher than Rs 387.4 million. The profile also says it uses the annual average landed cost of diesel and LPG.

Carbon for each rupee

• Electricity: 0.675 kg per kWh / Rs 6.5 = 0.104 kg of CO2 a rupee.
• Diesel: 2.645 kg a litre / Rs 52 = 0.051 kg a rupee.
• LPG: 2.98 kg a kg / Rs 65 = 0.046 kg a rupee.
• So at these 2015 prices a rupee saved on power avoids about twice the CO2 of a rupee saved on diesel or LPG. Prices have moved since, so divide the factor by what you pay now.

Electricity line, step by step

• Units: 59,600,000 kWh x 0.675 = 40,230,000 kg = 40,230 tonnes of CO2
• Bill: 59,600,000 x 6.5 = Rs 387,400,000
• Per rupee: 40,230,000 / 387,400,000 = 0.104 kg
• Share of the cluster's 48,458 tonnes: 40,230 / 48,458 = 83.0%

TERI's 2015 quantities and prices with today's factors, our arithmetic. Diesel and light diesel oil are both taken at the diesel factor.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your own units and factors are on file for each month. The rupee ratio is a division you do on your own bills.
