Objective: We discuss the role of diversification on dependency and security of energy supply. A system dynamics model with especial focus on the role of renewable energy resources (as a portfolio) on Finland’s energy dependency is developed. The purpose is also to cover a part of research gap exists in the system dynamics modeling of energy security investigations. Methods: A causal loops diag...

Geothermal energy is one of the cleanest sources of energy which is gaining importance as an alternative to hydrocarbons. Geothermal energy reserves in China are enormous and it has a huge potential for exploitation and utilization. However, the development of the geothermal industry in China lags far behind other renewable energy sources because of the lack of fiscal and taxation policy suppor...

This paper presents an alternative way of making predictions on the effectiveness and efficacy Renewable Energy (RE) policies using Decision Trees (DT). As a data-driven process for decision-making, analysis uses target achievement, predicting whether or not RE will likely be achieved (efficacy) to what degree (effectiveness), depending different criteria, including geographical context, charac...

In recent two decades, countries focused on minimum extraction of fossil fuels and utilized the renewable energies based on countries' policies and the environmental considerations. Thus, choosing the best renewable energy alternative is a significant role to investment on them. Among the classical decision approaches that have used in the literature, the hesitant fuzzy sets (HFSs) theory is ap...

Renewable energy has made significant inroads in addressing growing demands on the African continent. However, progress towards SDG 7 is still limited and difficult to trace. Furthermore, results-oriented rationale of SDGs means that both policy change dimension environmental justice are not covered properly. We argue concept may provide a powerful tool offset looming trade-offs enhance co-bene...

research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...

This paper addresses the claim that environmental policies stimulate domestic economies. I parse the claim into two sequential parts: the effect of policies on innovation and the effect of that innovation on resulting manufacturing production. Each of these activities innovation and manufacturing can either take place at home or abroad, and where they take place determines the consequences for ...

We present a bilevel optimization approach to designing effective and efficient incentive policies for promoting renewable energy. The effectiveness of an incentive policy is its capability to achieve a goal that would not be achievable without it. Renewable portfolio standard is used in this thesis as the policy goal. The efficiency of an incentive policy is measured by the amount of intervent...

Sustaining rapid economic growth and satisfying increasing energy demand while limiting greenhouse gas (GHG) emissions is a central challenge in India. Proposed policy solutions should be evaluated according to their impacts on the energy system and the economy to identify efficient policies. I have developed an energy-economic model for India that provides a comprehensive foundation for analyz...
