Objectives
Contents The module begins with an introduction to the energy problem and then the various forms of energy are defined. In the second part, the conventional (fossil) energy resources are analysed and thus the coal and the petroleum cycles. In the third part, the principles of the renewable energy resources are studied in depth, where types, such as energy from biomass, solar energy and wind energy, are examined. Finally, the module concludes with an introduction to the structure of the electric market and to energy policy.
Extended Syllabus - The energy problem: present and future. Evolution of reserves, production and consumption of the main fossil and renewable energy resources worldwide and regionally.
- Introductory concepts and definitions: energy, kinetic energy, potential energy, forms of “internal” energy of a system, unit of measurement of energy. Power and related unit of measurement; interpretation of energy from a macroscopic point of view. Microscopic interpretation of work and energy; the laws of thermodynamics, energy transformations and irreversibility.
- Review of the main pollutants connected to energy systems and related environmental impacts.
- The cycle of coal. Extraction and preparation: main technologies and related impacts. Transport and handling: methods, problematic aspects and related countermeasures. Main combustion technologies for the electricity production, related pollutants and pollution reduction and/or prevention technologies. Coal processing. Dry distillation; gasification; liquefaction; "clean" coal.
- The cycle of oil and natural gas. Main impacts related to the extraction of crude oil and natural gas. Non-conventional hydrocarbons. Transport and processing of fossil hydrocarbons. Combustion for electricity production: main technologies; steam turbine, gas turbine and combined gas-steam cycle.
- Introduction to the use of biomass for energy purposes. Energy accumulation in biomass. Main limits and advantages of the use of energy biomass. Main thermochemical and biochemical transformations of raw biomass.
- Solar energy. Solar constant. Albedo. Power density and average insolation on the ground. Direct and diffused component of solar radiation. Thermodynamic solar. Main solar concentration technologies. Parabolic mirrors in point and linear focus. Main solar concentration technologies: mirror field with central tower. Low temperature thermal solar: flat solar collectors and vacuum tube collectors. Photovoltaic power generation.
- Wind energy. Direction and wind speed. Mechanical power contained in the moving air. Operation of wind machines. Vertical axis machines, horizontal axis machines. Air flow through the rotor. Electricity produced by an aerogenerator. Wind farms. Advantages and disadvantages of wind energy.
- Overview of other energy transformation technologies.
- Transformation of the structure of the electricity market (from monopoly-based to competitive) and of the product "electricity" (from commodity to diversified mix of services). The role of distributed generation (DG) in the new context of the electricity market. Examination of some peculiarities of the DG. Opportunities related to the development of the DG and limits to its dissemination. Energy policy measures for the promotion of DG.

Methods of Provision
Teaching Methods Active teaching methods will be favoured as far as possible, with case studies and/or analysis of scientific articles, multimedia study aids, specialised software demonstration, group work and simulations, visits and seminars.
Evaluation methods Verification of learning:
The exam consists in an oral interview aimed at verifying the learning, the conceptual mastery, the vocabulary and the ability to interpret and synthesise. The examination questions include both descriptive and critical elements. Grading uses a 30-point scale.
