What is energy ? : 

What is energy ? Energy lights our cities, powers our vehicles, and runs machinery in factories. It warms and cools our homes, cooks our food, plays our music, and gives us pictures on television. Energy is defined as the ability or the capacity to do work.

Types of Energy : 

Types of Energy Energy is the ability to do work and there are many types of energy Mechanical Energy Heat Energy Chemical Energy Electrical Energy Gravitational Energy

Mechanical Energy : 

Mechanical Energy Mechanical Energy is the energy of motion that does the work like the wind turns a windmill.

Heat Energy : 

Heat Energy Heat Energy where motion or rise in temperature is caused by heat like a fire in your fireplace.

Chemical Energy : 

Chemical Energy Chemical Energy is the chemical reaction causing changes; food and fuel both store chemical energy.

Electrical Energy : 

Electrical Energy Electrical Energy is when motion, light or heat is produced by an electrical current like the electric coils on your stove.

Gravitational Energy : 

Gravitational Energy Gravitational Energy where motion, like water going over a dam, is caused by gravity's pull. When energy is used it's changed from one form to another. Let's look at an example of how energy changes: The gravitational energy of falling water changes to mechanical energy when it turns a turbine. The energy from the turbine turns a generator that creates electricity that you use to turn on a light.

WHY ENERGY MANAGEMENT ? : 

WHY ENERGY MANAGEMENT ? India is a Developing nation. Its per capita Energy Consumption is very low. To achieve Economic Growth, we need to & have to use more & more energy to increase the pace of development. We need to increase the manufacturing of good in Quality & Volume.

Slide 12: 

It is estimated that Industrial energy use in developing countries constitutes about 45-50 % of the total commercial energy consumption. Much of this energy is converted from imported oil, the price of which has increased tremendously so much so that most of developing countries spent more than 50 % of their foreign exchange earnings. Not with standing these fiscal constraints, developing countries need to expand its industrial base like us.

Slide 13: 

if it has to generate the resources to improve the quality of life of its People. The expansion of industrial base does require additional energy inputs which becomes more & more difficult in the present scenario. Generation of power needs resources. Resources available on earth are of Diminishing Nature. It is getting depleted very fast with time as use is increasing exponentially

Slide 14: 

There are some resources, which are Renewable E.g. Solar Power, Wind Power and Geothermal Power. Technology is also being developed to harness these Renewable Resources to generate Power. The capital investment requirement is very high as compared to normally available resources. It can be quoted here that with the available technology, we could hardly generate 5% of total power generation as on date .Hence, to restrict the use or increase the life of diminishing type of resources.

Slide 15: 

Let us see the other aspect of life, whereas everybody can’t understand all technical reasons or benefits of the whole world until he himself realizes some benefit for his action or efforts. In this competitive world, cost competitiveness is very very essential for survival of every individual. To establish any work / motive or task, energy in one or other form is an essential component.

Slide 16: 

Thus the need to conserve energy, particularly in industry and commerce is strongly felt as the energy cost takes up substantial share in the overall cost structure of the operation. Hence it calls MANAGEMENT OF ENERGY or in other words MANAGEMENT OF RESOURCES or ENERGY CONSERVATION

HOW TO MANAGE ? : 

HOW TO MANAGE ? Energy management is not by chance / incident / accident. It is a Mission with a Target. It can’t be done single handedly or by sitting on a table. It needs coordinated effort by team of energy conscious people with a milestone to be established. Very concerted efforts in a planned manner to established Energy Management. Strategy needs to be established based on the Target of Energy Conservation.

Strategy / Methodology of Energy Management: : 

Strategy / Methodology of Energy Management: Having established the need of Energy Management / Conservation. A systematic approach needs to be discussed and concluded. Same of steps to reach to the target of Energy Conservation can be listed : -

Slide 19: 

1) Identification of Inefficient areas / Equipments: - Enlistment or knowledge of type of energy being used. Study of machines / Technology employed. Process study and identification of major energy consumption areas. In depth process study to identify the inefficient use of energy.

Slide 20: 

2) Identification of Technology / Equipment requirement. 3) Discussion, Brain storming & Conclusion of resources requirement. 4) Management of resources like Manpower, Machine or Technology. 5) Evaluate your actions / efforts to estimate the Rate of Return

Slide 21: 

6) Implementation of New Process / New Technology / New Machines. 7 “Re-evaluate your actions / Your Efforts INEFFICIENT ACTION / EFFORTS CAN NOT GIVE EFFICIENT RESULTS.” “ONLY EFFICIENT EFFORTS & ECONOMIC IDEAS NEED TO BE TESTED)

ENERGY MANAGEMENT TECHNIQUES: : 

ENERGY MANAGEMENT TECHNIQUES: 1) Self knowledge & Awareness among the masses 2) Re-engineering & evaluation 3) Technology Up gradations

1. Self Knowledge & Awareness Among The Masses: : 

1. Self Knowledge & Awareness Among The Masses: For the successful Energy management & implementation, the knowledge of process & machine for the leader is very important. On the first instance, there is always a resistance from the user. There might be psychological mind blocks in the user’s mind. This needs to be made known & clarified It is further more important to make the owner of the process understand the cost benefit of the energy conservation.

Slide 24: 

Creating Awareness to the process owner can give most economic & low cost solutions to save energy. We have realized about 5 % of energy saving just because of Awareness of the people.

Slide 25: 

e.g.:- A. We advertised the concept of “Zero Production = Zero Power consumption”. People realized this concept and they started switching off the Auxiliaries during Idling of main machines. B. Later on, we introduced microprocessor-based timer to auto switch off auxiliary equipments during Idle period of machines.

2. Re-engineering and Technology Up gradations: : 

2. Re-engineering and Technology Up gradations: After utilizing the low cost or awareness concept, we need to do in depth study the process /machine. We need to ascertain, the scope & extent of Energy Conservation in the area under consideration. Evaluate the existing situation / employed technology in terms of process requirements & production capacity & capability. Sometimes, we do land into a situation of handicap with machine capacity & capability for the sake of Energy Conservation. It must not be done

Slide 27: 

Once it is established, that there is a potential of energy optimization. We need to start evaluation & re-engineering of the process / equipment. It may be terms of layout, motor capacity, types of starters employed, nature of loads etc

3. Technology Upgradations: : 

3. Technology Upgradations: After having established the scope of energy conservation in the specified area. The latest technology availability is suitability, sustainability & pricing needs to be studied Economics needs to be worked out like Pay back period, Return of Investment, Quality of energy savings etc.

Please remember “ BETTER THE DIAGNOSIS, BEST WILL BE THE RESULT. ”
