Electricity is a crucial input to the industrial production of South Korea. Estimating the demand function for electricity in the manufacturing sector is an important task because electricity consumption in the manufacturing sector accounts for 56.3% of total electricity consumption in South Korea. Thus, this article tries to estimate the demand function for industrial electricity in the manufacturing sector of South Korea using cross-sectional data for analyzing the influence of manufacturing firms’ characteristics. To this end, 946 observations collected from a nationwide survey of manufacturing firms in 2018 are used and analyzed. As a robust approach, the least absolute deviations estimation method is applied to obtaining the demand function. The results show that the price elasticity and the sales amount elasticity of the industrial electricity demand are estimated to be −0.9206 and 0.2568, respectively, which are statistically significant at the 1% level. Furthermore, the economic benefits of industrial electricity consumption are computed to be 1.46 times as great as the price of electricity. The results of this study can be utilized in policy planning, making, and evaluation.

South Korea is promoting the “Renewable Energy 3020 Plan” to expand the proportion of renewable energy (RE) from 2.2% in 2016 to 20% in 2030. Since the plan could lead to an increase in electricity rates, public acceptance of it is an important key to determining its success. This article examines the public acceptance of the plan by employing contingent valuation (CV). A nationwide CV survey of 1000 households was performed to collect the data on the willingness to pay (WTP) for implementing the plan using electricity charges as a payment vehicle during October 2018. More specifically, a dichotomous choice question to ask interviewees whether they have an intention of paying an offered bid and a spike model to treat the zero WTP observations were employed. The estimate for monthly WTP was KRW 3646 (USD 3.27) per household. When 10 years of the payment period presented in the survey and forecasted values of residential RE electricity consumption from 2018 to 2030 were used, the WTP was worth KRW 60.4 (USD 0.05) per kWh in 2018 constant price. The WTP amounts to 56.5% of the price for residential electricity (KRW 106.9 or USD 0.10 per kWh). That is, the RE electricity produced through implementing the plan has a premium of 56.5% over the current electricity. Overall, it is concluded that public acceptance of the plan has been secured.

This study evaluated energy consumption by Agudu Farms Limited (AFL) that processes maize and cassava into flour for human consumption. The objectives of study included to determine energy contribution to processing cost, to minimize the processing cost and to propose a new selling price per unit of sale of the product. The study materials included; a multi-meter, stopwatch, electrical appliances’ nameplates and bills, fuel purchased receipts, and production records. Data was collected through detailed energy audits and measurements of present electricity consumption. This data was converted into energy intensities, rates and costs, and analyzed. The monthly energy intensity plotted on bar charts using Microsoft excel and  the results showed that diesel had the highest consumption variation of 3500 kWh/t, electricity 200kWh/t and labor 110 kWh/t. The percentage of energy contribution to processing cost was 33%. In monetary terms, the processing cost per hour of operation showed average value of ₦830. Whereas, the minimum production cost per hour using Tora software showed ₦767. The new product price per ten-kilogram (10kg) unit of sale of maize flour, using break-even analysis, showed ₦2864.  The study observed that diesel contributed more to production cost than electricity and labor and therefore, recommended the setting up of an energy monitoring team to monitor procurement and control utilization of diesel to reduce production cost.

This paper presents an energy performance assessment on an educational building in Barranquilla, Colombia. The electricity consumption performance was assessed using the software DesignBuilder for two different Air Conditioning (AC) systems. The current electricity intensity is 215.3 kWh/m2-year and centralized AC systems with individual fan coils and a water chiller share 66% of the total consumption and lighting at 16%. The simulation of the AC technology change to Variable Refrigerant Flow (VRF) resulted in an improvement of 38% in AC energy intensity with 88 kWh/m2-year and significant savings in electricity consumption and life-cycle cost of AC systems in buildings.

Energy evaluation is an important means for an organization to be more competitive in the global era. IKE or the intensity of electricity consumption is a term used to evaluate energy consumption in a system (building). IKE value is obtained by comparing the total use of electrical energy in building area. The evaluation process is done by collecting historical data from Kartika Husada Tambun hospital building., such as  data of building area, data of the use of electricity, and the budget spent of electricity needs. From the calculation results, IKE value of the Kartika Husada Tambun Hospital in 2016 was 160,73 kWh / m2/ year, the IKE value in 2017 was 166,04 kWh / m2/ year, and 2018 was 142,79 kWh / m2/ year. This result is in the efficient category because it does not pass the IKE standard for electricity for a hospital building of 380 kWh / m2 per year. For cost savings the author recommends the application of energy-saving technology
