Economic Evaluation of the Implementation of Policy Actions in the Field of Energy Efficiency

Abstract

This paper presented an analytical tool, based on the cost-benefit analysis instrument, intended to be used to estimate both the financial and economic impacts related to the implementation of policy actions and/or projects (interventions) in the field of energy efficiency. The proposed guidelines are intended to provide relevant information and guidance on why and how to conduct financial and economic assessment to a relatively large number of institutions involved in the preparation and appraisal of energy efficiency actions.

Vehicular Fuel Consumption and CO2 Emission Estimation Model Integrating Novel Driving Behavior Data Using Machine Learning

“…Moreover, the monthly fuel consumption [L] was recorded using the internal measurement devices of the vehicles. The monthly CO 2 emission E CO 2 was then calculated as a secondary parameter based on the assumption that engines emit 2.3 kg of CO 2 for every 1 L of gasoline consumed [29,30], and that this relationship holds true for all vehicles under consideration. The E CO 2 can be calculated using Equation (1).…”

“…A 5-fold cross-validation was conducted to the RFR model by utilizing a grid search technique using the training set data to select the optimal hyper-parameters of the RFR model, as illustrated in Figure 1. In the RFR model, the hyper-parameter candidates were selected empirically as follows: 'n_estimators': [200, 600, 1000]; 'max_features': ['auto', 'sqrt']; 'max_depth': [10,20,30]. To gauge the performance of the model, the coefficient of determination (R 2 ), root mean squared error (RMSE), and mean absolute error (MAE) were used as the performance metrics.…”

Energy Risk Management and Cost of Economic Production Biodiesel Project

“…Measuring the value of economic projects considers as an important indicator of investment decisions It can demonstrate generally measured through 3 indicators: (1) NPV -It is the calculation of the difference in the present value of the revenue that is expected to be received each year throughout the life of the project and the present value of the expenses paid out; (2) Benefit -Cost Ratio (B/C Ratio) -It is finding the numerical value between the present value of revenue throughout the project life divided by the current value of the cost throughout the project life. The benefits will be suited when B/C ratio is greater than 1 (Vitliemov, et al, 2019) and (3) Internal Rate of Return (IRR) -It is reflecting the return on investment at the point of capital by comparing with the interest rate or financial cost or the cost of the project that is more or less than the interest rate or financial cost (Hardacer, et al, 2004;Lee, et al, 1980;Warren, 1982;Illes, 2002;Ross, et al, 2005). Tangjitprom and Romprasert (2019) have mentioned that "Renewable Energy" for community is mirroring the society's choice and worth for continuing as community project investment supported.…”
