Obiettivi dell'insegnamento

After a brief overview about the global energy situation and the main challenges in energy sector, both renewable and non-renewable primary energy sources are presented in terms of reserves, availability, needs and demand forecasts. The primary energy conversion to final demand for electric energy and heat is then presented: statistics about thermoelectric generation, cogeneration and renewables are illustrated. Moreover, the primary and electric energy balances of countries are analyzed. The first part of the course is devoted to a general overview of the energy sector, analyzing the energy flows and its transformations from primary resources to final energy products. The main challenges in the energy sector for future decades are also highlighted thus giving constrains and opportunities for energy technology development. The input-output matrix of a country is also introduced in order to analyze the cost of products in different countries and gather a more informed understanding of the link between- energy system and national economy. The second part of the course is devoted to deepen advanced exergy based methodologies for systems analysis. After a brief review of thermodynamics fundamentals, the exergy balance is derived and all of its components analyzed. Standard exergy analysis of energy systems is then discussed. Thermoeconomics is presented as a theoretical framework for economic and environmental cost accounting, system diagnosis and optimization. The course aims at deepening advanced methodologies for energy conversion systems analysis as instrumental tool able to evaluate the performance of the energy system from a Life cycle perspectives including different externalities. Starting from the traditional exergy analysis, the course explores the application of exergy to economics and cost analysis (the so called Thermoeconomics), introducing advanced methods to assess the economic and the environmental impact of energy systems.

Risultati di apprendimento attesi

The learning outcomes may be aggregated into four areas of knowledge


1. The students will learn the trends of the global energy challenge and the methodological approach to the national energy balance. They will learn the foundation of Exergy analysis, deepening chemical exergy and will extend their knowledge to enclose the combined approach of exergy and economic balances as fundamental equations adopted thermoeconomics. They will learn the basic of Input-Output analysis from the theoretical perspective of the single and multiple sector approach.


2.  The student will be able to apply their knowledge by assessing the energy balance at country level. They will be able to solve exergy analysis problems applied to complex energy systems and to evaluate the specific cost of products broken down into the irreversibility and monetary-related contribution with the purpose of optimizing the current configuration of the system under analysis


3. The students will learn how to judge the energy economy of countries by using a proper set of indicators. They will be then able to perform a shock analysis on input-output national matrix in order to evaluate the effect of a given policy aiming at reducing the overall consumption of primary energy or reducing emissions and pollutants.


4. The students will work in team and present their project work based on a given format, time and audience

Modalità di valutazione

The lectures are given ex cathedra, nevertheless a participatory approach is always envisaged. Part of the course is devoted to methodological exercises about the use of indicators at country level and application of Thermoeconomics.

A project work will be carried out in team and it will be about “Shock analysis on national Economy: the impact of policy”. The project work evaluation will allow the assessment of:

  • They will apply their knowledge by working on a Muti-Sectorial and Multi-Regional Input–Output Approach to a given country. They will use. indicators to understand the energy situation and they will draft a policy whose impact will be evaluated in economic and environmental terms.
  • The will be able to make judgement since the students will select a specific policy after understanding the energy situation of the country.
  • The students will have to work in team and communicate each other to finally prepare a talk for the oral presentation of the project work.

The project work is highly recommended and it can provide a rating (0-6) to be added to the evaluation of the written text.  The project work will be complement with a written test will assess individually

  • The knowledge of the students since they will have to respond to a set of theoretical questions.
  • Their capacity to apply knowledge and understanding since the students will have to solve some exercises.
