Course Description

• The course includes the participation of several faculty members andpresents an overview of the world and national energy situation. It includesthe analysis of steam, gas turbine, combined cycle, internal combustionengine, solar thermal, hydropower, solar photovoltaic, and wind powerplants. Technologies and feasibility of using biomass as an energy resource

are also analyzed. The environmental and social impact of the differentenergy conversion systems is studied. The course includes an introductionto energy efficiency in industry and design for energy efficiency.

Fundamental Concepts

• Today´s main use of energy source:

• Electricity generation

• Transport


10/16


WORK:

• Work is done when a force is applied to an object and theobject is moved through a distance.

• Product of the force and the distance over which the force isapplied.

• Displacement of a body under the action of a force.


11/16


ENERGY:

• the ability of a system to perform work.

• Energy is a property of objects which can be transferred

to other objects or converted into different forms, butcannot be created or destroyed.

• It may exist in potential, kinetic, thermal, electrical,chemical, nuclear, or other various forms.

Tonne of oil equivalent (toe)

The tonne of oil equivalent (toe) is a unit of energydefined as the amount of energy released by burning one

tonne of crude oil. It is approximately 42 gigajoules,although as different crude oils have different calorificvalues, the exact value is defined by convention; severalslightly different definitions exist. The toe is sometimesused for large amounts of energy.
