Industry Handbook

What‘s it all about?

• Industry is one of the main users of Energy• How is energy used for industrial processes?• What are the problems of energy

consumption on such large scale?• Where can losses be reduced?• How can processes be designed to be more

efficient?

Industry Handbook

Content

• Content is based on the Industrial and Engineering pathway of efficient energy use

• The Handbook contains information that’s useful mainly for Students with a focus on Economics and Engineering

Industry Handbook

Content

• Introduction to energy• Sources of energy• Transformation and use of energy • Transforming Energy (Energy Carriers)

– Industry use• Energy Management• Efficient use of Energy in the Paper Industry

Industry Handbook

Chapter 1 - Introduction to energy

• What is energy and what does it mean?• Which measuring Units are used?• How do we depend on energy?• Environmental problems of large scale

energy production.

Industry Handbook

Chapter 1 - Background

• Students should get a general idea of “Energy”, what it is and how they depend on it

• By considering examples they should experience the amount of energy needed for different things in everyday life

• By understanding the units of Energy measurement, they should be able to understand reported information on the energy demand of different items of equipment

Industry Handbook

Chapter 1 – How to teach

• Let the students find out where they use and depend on Energy by setting up a group work

• Find out how much energy is consumed by different equipment or actions in the students’ everyday life

Industry Handbook

Chapter 2 - Sources of energy

• What are the main energy sources used nowadays?

• How much energy is produced from renewable sources?

• What are the problems with non-renewable energy sources (fossil & nuclear)

Industry Handbook

Chapter 2 - Background

• Student can examine statistical data, to appreciate the scale of different energy sources and use

• By comparing the performance of different EU countries the use of renewable energy sources and their potential for increased use is demonstrated

• The problems with fossil and nuclear energy sources are shown by different examples (peak oil, pollution, etc.)

Industry Handbook

Who uses what fuel?

Industry Handbook

Peak oil

• The production of oil is expected to shortly reach a maximum and then decrease

EXERCISE• Source data: With

current known reserves of oil, gas and coal, when will we run out of fossil fuels?

Industry Handbook

Chapter 2 – How to teach

• Try to mark out clearly the difference between renewable and non-renewable energy sources by discussing the problems with fossil fuels (group work, pros vs. cons)

• Let students find out if and where they can find renewable energy sources in their surroundings

• Highlight the problems of greenhouse gas emissions by using reports from (maybe your local) media or the Internet

Industry Handbook

Chapter 3 - Transforming of Energy and Industry Use

• Chapter divided in two subchapters:

3.1 Transforming Energy (Energy carriers)

3.2 End uses of energy in industry (Level II)

Industry Handbook

3.1 - Transforming Energy (Energy Carriers)

• What are the most common Energy carriers?• How are fuel and electricity produced?• How is Energy transformed? • How do energy flows look like if you consider

a whole nation and how big is the amount of energy needed by Industry? (->Level II)

• What is a national energy balance? (->Level II)

Industry Handbook

3.1 - Background

• By explaining fuel and electricity production students should get information on the main energy carriers used nowadays

• The potential to gain more efficiency should be marked out by the explanation of Combined Cycle and Combined Heat power plants

• Using the example of an old National Energy Balance of Ireland, students should get an understanding of the different ways of energy consumption throughout a whole nation

Industry Handbook

Energy flows & uses

Industry Handbook

National energy balance

Industry Handbook

Chapter 3.1 – Ways of Teaching

• Let the students find out what the main sources of electricity production in their country are

• Try to mark out which renewable energy sources are used in your country for electricity production

• Use Experiments for direct understanding of energy efficiency measures

Industry Handbook

3.2 - End uses of energy in industry

• Where are the significant energy losses in different types of industrial equipment (boilers, fans, compressed air systems, etc.)?

• How can energy losses be reduced?• Which cooling and heating fluids are used?

Industry Handbook

3.2 - Background

• 3.2 consists mainly of Level II information for Students with a focus on engineering

• The main consumers of energy within an industrial plant should be identified by some examples

• The potential to reach better efficiency is discussed by different industrial equipment (boilers, electric motors, etc.)

Industry Handbook

Chapter 3.2 – How to teach

• Work through the different parts of a plant in the Handbook (boilers, fans, etc.) especially mentioning their optimisation potential

• Think of an excursion to an industrial plant and try to find out about their energy saving efforts on the different process units

Industry Handbook

Chapter 4: Energy Management

• What is Energy Management?• What are the key elements of the Energy

Management System (EMS)?• What are the goals of an energy

management system? • How can such a system be implemented (in

industry and business, but also in schools?

Industry Handbook

Energy Management System

Industry Handbook

Chapter 4 - Background

• The benefits of an EMS for a company are marked out by different examples

• By discussing an energy policy, students should understand that energy efficiency measures have to affect the whole company

• Students should get to know that a systematic approach is the best way to increase energy efficiency

Industry Handbook

Chapter 4 – How to teach

• Try to work out an Energy Policy for your school

• Work through the different steps of an EMS using the example of your own school

• Try to establish an EMS at your school, designed by the students, with your help

Industry Handbook

Chapter 5: Efficient use of energy in paper Industry

• Level II information on the practical application of energy saving measures.

• Case study on the efficient use of energy in paper industry.

• General Information on the paper production Process

• Different paths of Energy saving in paper Industry

• Experimental guide on “How to make your own paper”.

Industry Handbook

Chapter 5 – How to teach

• Mainly for students with a focus on engineering

• Try to show the energy flows in a large industrial process

• Students should learn how energy efficiency measures are implemented in an industrial process on this special case study

• Use the “Make your own paper” experiment to show students where energy is needed in a large industrial process (drying, heating, etc.)
