-definitions:
energy; types of forms; systems; transformation; conventional
and non-conventional energy sources; electric power
generation and utilization; management; etc.
-Energyis the ability to do work.
-Workcan bedefinedas transfer ofenergyor Workis the application of a
force over a distance.
-Poweris the rate of doing workor expending energy.
-Energytransformationorenergyconversionis the process of changing one
form ofenergyto one other.

4. GENERAL INTRODUCTION CONT…
Six Forms of Energy:
Mechanical
Heat/Thermal
Nuclear
Electrical
Light/Radiant
Chemical

5. GENERAL INTRODUCTION CONT…
•Energy that moves objects
from place to place
•You use mechanical energy
when you kick a ball or turn
the pedals of a bicycle
•Other examples include
water flowing in a stream,
tires rolling down a road and
sound waves from your iPod.
Mechanical Energy

6. GENERAL INTRODUCTION CONT…
•Energy released by a chemical
reaction
•The food you eat contains
chemical energy that is released
when you digest your meal
•Wood, coal, gasoline, and
natural gas are fuels that contain
chemical energy
Chemical Energy

7. GENERAL INTRODUCTION CONT…
•Energy that comes from the
electrons within atoms
•It can be generated at a power
plant or inside a battery and can
power everything from remote-
controlled cars to refrigerators
•Lightning and static electricity are
also forms of electrical energy
Electrical Energy

8. GENERAL INTRODUCTION CONT…
•Energy created by the
motion of atoms and
molecules that occurs
within an object
•Thermal energy exists
when you heat a pot of
water on a stove
Heat (Thermal) Energy

9. GENERAL INTRODUCTION CONT…
•Energy contained in the nucleus of
an atom
•Nuclear energy is released when
nuclei are split apart into several
pieces, or when they are combined
to form a single, larger nucleus
Nuclear Energy

10. GENERAL INTRODUCTION CONT…
•Energy that can move through
empty space
•The sun and stars are powerful
sources of radiant energy
•The light given off by light bulbs and
campfires are also forms of radiant
energy
Light (Radiant) Energy

11. GENERAL INTRODUCTION CONT…
All forms of energy can be converted into
other forms of energy
Energy Conversion

12. GENERAL INTRODUCTION CONT…
Process of Energy Use

13. GENERAL INTRODUCTION CONT…
•Energy conservationrefers to reducingenergyconsumption through using
less of anenergyservice.
•Energy conservationdiffers from efficientenergyuse, which refers to using
lessenergyfor a constant service.
•Energy conservation andefficiency are bothenergyreduction techniques.
•Energy management includes planning and operation ofenergyproduction
andenergy consumption units. Objectives are resource conservation,
climate protection and cost savings, while the users have permanent access
to theenergythey need.

14. COURSE OUTLINE
•Energy sources and conversion techniques
•Global and national energy assessments
•Renewable energy resources
•Solar and wind energy systems
•Waste energy technology
•Energy conservation & management
•Energy auditing and costing
