The following paper focuses on energy efficiency applied to a company dedicated to the conservation and freezing of seafood products located in the city of San Francisco de Campeche, Camp, Mexico. For this, a theoretical study is carried out to determine the energy saving potential of one of the refrigeration systems currently installed in the company to fulfill the hypothesis of obtaining savings of up to 3% in energy consumption by reducing 1 °C the condensing temperature of the system. The main thermal loads of the system are Mayan octopus, shrimp, and fish (various). With the help of the Genetron Properties Software, the different calculations are carried out by making variations in the condensation and conservation temperatures, without varying the thermal load, but considering a correct and incorrect heat exchange of the condensing units with the outside.

The paper assesses thermomodernisation measures aimed at improving energy efficiency of dwelling houses in a city quarter in Upper Silesia, Poland. The area was encompassed by the city council’s program of emission restriction that promoted energy saving activities. The assessment was carried out by means of thermographic examination. It confirmed the fact that the thermomodernisation measures taken so far provided considerable improvement, but did not solved all issues. Further works should be undertaken on the basis of thorough examination of the current condition of the buildings.

Consumption Intensity

This article proposes using passenger transportation energy intensity to measure the energy utility efficiency and energy-saving potential of the passenger transportation, uses the complete decomposition model to decompose the passenger transportation energy intensity from 1990 to 2007, and then investigate how various factors impact passenger transportation energy intensity. As is shown in the results, transportation structure increases passenger transportation energy intensity, while energy efficiency decreases it, however the decline is limited. Thus energy saving caused by adjustment of transportation structure is much more considerable.

This study evaluates energy efficiency of pastoral (PDFs) and barn (BDFs) dairy farming systems in New Zealand through application of data envelopment analysis (DEA) approach. Two models constant return to scale (CCR) and variable return to scale (BCC) of DEA were employed for determining the technical (TE), pure technical (PTE) and scale (SE) efficiencies of New Zealand pastoral and barn dairy systems. Further, benchmarking was also performed to separate efficient and inefficient dairy farms and energy saving potential was identified for both dairy systems based upon their optimal energy consumption. For this study, the energy inputs data were taken from 50 dairy farms (including PDFs and BDFs) across Canterbury, New Zealand. The results indicated that the average technical, pure technical and scale efficiencies of pastoral (PDFs) dairy systems were 0.84, 0.90, 0.93 and for barn (BDFs) systems were 0.78, 0.84, 0.92, respectively, showing that energy efficiency is slightly better in PDFs system than the BDFs. From the total number of dairy farms 40% and 48% were efficient based on the constant return to scale and variable return to scale models, respectively. Further, the energy saving potential for PDFs and BDFs dairy systems through optimal energy consumption were identified as 23% and 35%, respectively. Thus, energy auditing, use of renewable energy and precision agricultural technology were recommended for energy efficiency improvement in both dairy systems.

Definition Of

The scientific and reasonable measure of energy-saving potential is the foundation based on which government departments of Jilin Province at all levels sets their energy-saving goals and make corresponding policies. With reference to the research results of other scholars, the paper gives a new definition of the energy-saving potential. The definition is expected to cancel the incomparability of industrial structures, levels of economic development, and level of technology in the medium and large cities of Jilin Province. DEA model is used to conduct the empirical research on the energy-saving potential of the medium and large cities of Jilin Province. The paper also gives an objective evaluation of the medium and large cities of Jilin Province and analyzes the results of the evaluation. For those inefficient energy cities, the paper determines the size of the energy-saving potential, and provides some countermeasures to improve energy efficiency from the perspective of technology advancement, energy-saving potential and industrial-scale upgrade.
