“…Conceptualising wind turbines as perfectly clean energy source may be a myopic view void of consideration of possible greenhouse gas emissions which manufacturing phase of the life cycle accounts for [19]. The embodied energy of a wind turbine refers to the energy requirements for the manufacturing, construction, installation and maintenance phases.…”

“…The embodied energy of a wind turbine refers to the energy requirements for the manufacturing, construction, installation and maintenance phases. When considering multiple wind turbines for a wind farm, other materials and components such as wiring, grid connection, transformers and access roads may also account for embodied energy of the wind farm [19]. Research [20] shows that wind turbine energy system is not entirely clean as different phases of the life cycle of a wind turbine are dependent on fossil fuel, therefore prone to carbon emissions.…”

The present study is an observation of the absence of policy focus and preparedness to address the greenhouse footprints and eventual climate change implications of some clean energy systems in the energy transition debate. Electric vehicles, wind turbines and photovoltaics constitute sample clean technologies under the study. A technical literature review is the approach for forming an appreciable understanding of the life cycle emissions of the sample clean energy technologies. Content and critical legal analysis are adopted for the examination of international and domestic legal regimes on clean energy sources, with India, China, the United States and the United Kingdom as domestic foci. The results of the study are the reality of supposed clean energy technologies as sources of greenhouse gas emissions, although considerably low compared to fossil fuel sources, and the apparent lack of international and domestic legal mechanisms to address the life cycle emissions of these technologies and the need for proactive policy actions.

“…The power which is generated from the wind turbine is the optimum as compared to the energy that is generated by the PV source, because of the cost per kilo watt in relation with seconds [1]. In recent times, the most commonly used WECS based on DFIG is employed, because it is used in variable speed applications, the subtraction of mechanical stresses, acoustic noises and improving the quality of power [2]. In the past few years, the hybridization of MPPT method and classical PID controller with fuzzy logic control methods are employed for increasing the performance of PID controller without altering the system stability [6].…”

The WECS based Doubly Fed Induction Generator (DFIG) system is presented in this paper which includes different MPPT control strategies for a grid connected system. The GSC gives the flow of power from the rotor part of DFIG up to the grid and the modulation of DC voltage. Here the cuckoo search algorithm based on MPPT is designed, to obtain a higher power from the changing speed wind turbine. The algorithms such as Perturb and Observe (P&O), Proportional Integral (PI) control and Fuzzy Logic Controller (FLC) are compared and their performances are evaluated. To design and develop the cuckoo search optimization based on MPPT for WECS, and to obtain optimum voltage regulation and power, thus improving the working performance, reducing the domain time and minimizing the performance indices. To simulate the different MPPT control methods, MATLAB/Simulink environment is used here.

“…Adopting the social revenue function described by Detert and Kotani (2013), Twidell and Weir (2015), and Savino et al (2017), the NPV for shifting to renewable energy sources is described by where π R,t is the annual revenue for after making the technological switch; R is the renewable source including wind, solar, hydro, and geothermal; I R is the overnight cost for renewables; P E is the domestic electricity price in the Philippines; Q E is the annual electricity generated from renewables; C R is the annual O&M cost; ρ is the discount factor equal to 1/1 + r; r is the social discount rate; t is the period of investment; and T R is the lifetime of renewable energy generation.…”

This paper aims to analyze the comparative attractiveness of either investing in various renewable energy sources or continue using coal for electricity generation in the Philippines. Using real options approach, this research evaluates the investment value and trigger prices of coal for switching technologies with some scenarios in coal price uncertainty and social discount rate. The results find that investing in renewable energy is a better option than continue using coal for electricity generation. Among renewable energy sources, geothermal is the most attractive to invest to, followed by wind, hydroelectric, and solar photovoltaic.
