This paper presents a method for multidisciplinary design optimization of offshore wind turbines at system level. The formulation and implementation that enable the integrated aerodynamic and structural design of the rotor and tower simultaneously are detailed. The objective function to be...

Sustainable energy decision-making requires comparing energy options across a wide range of economic, environmental, social and technical implications. However, such comparisons based on quantitative data are currently limited at the national level. This is the first comparison of 13 currently...

Pakistan is going through a severe energy crisis due to an increasing gap between demand and supply. Its current energy needs are heavily dependent upon conventional thermal power plants which mainly use oil and gas. In addition to the economic problems associated with importing oil for...

Electricity availability and stability have a great contributory share of industrialization growth rate, poverty statistics, unemployment, foreign investors' participation, medium and small scale encouragement, crime and mortality rates recorded in any country. Nigeria as a country has been...

The pace of the global decarbonization process is widely believed to hinge on the rate of cost improvements for clean energy technologies, in particular renewable power and energy storage. This paper adopts the classical learning-by-doing framework of Wright (1936), which predicts that cost will...

The levelized cost of energy (LCOE) approach has become popular, especially in the field of renewable energy. We argue that when assessing levelized cost of energy, different rates should be used for borrowing and discount rates. We further argue that the risk-free rate should be used for...

The paper presents an economic cost evaluation on the feasibility of offshore wind turbine (OWT) farms development in Nigeria, using a 500 MW OWT farm as an incident study. A developed model was used to evaluate the economic cost of the OWTs at different phases of the project. Additionally, the...

The aim of this paper is to enunciate a new way to estimate levelized cost of electric energy (LCOE), considering emission of greenhouse gases cost, by taking the theoretical cost of avoiding pollution as the emission cost. In this way, it would be comparable LCOE from different sources of...

The growing demand for energy, commitments taken to reduce greenhouse gas emissions, fossil fuel depletion and other issues enforced to accept the decision to analyze financing issues of renewable energy sector worldwide. This paper addresses two financing issues – financing channels and...
