2. When it is put into use and when it is consumed. The time limit of energy consumption statistics of industrial enterprises is based on the first production process.
3. The energy consumption of repeated recycling cannot be calculated repeatedly. Such as the recovery and utilization of waste heat and waste energy, are no longer included in consumption.
4. Energy consuming working fluids (such as water, oxygen, compressed air, etc.). ), whether purchased or produced, are not included in energy consumption.
5. The energy produced by an enterprise, as the raw material and fuel for the enterprise to produce another product, should be accounted for and consumed separately. For example, coal mines use raw coal to produce clean coal, coking plants use coke to produce gas, and refineries use fuel oil to generate electricity. However, the consumption of semi-finished products and intermediate products consumed in the production process of products is not counted. For example, after a refinery produces fuel oil from crude oil, it uses the fuel oil to produce other petroleum products. In this case, neither the output nor the consumption of fuel is calculated.
