What does Efficiency mean?
Efficiency means all changes that result in a reduction of inputs used for a given service or level of activity.
This reduction in the input consumption is not necessarily associated to technical changes, As it can also result:
From better organization and management
Better MIS & Control
this concept is called efficiency

Energy Efficiency
Energy Efficiency means: Using Less Energy to achieve same or better output
Energy Efficiency Project refers to:
Energy Efficiency Most Cost –Effective Solution
Reducing the Energy Supply/Demand Gap
Mitigating Climate Change Impacts
Without compromising Economic development

Energy Efficiency
The first aim should be:- To gain control on consumption and costs by assessing current use.
- by taking steps to incorporate energy efficiency into the corporate culture.
This involves:• Identifying, and quantifying, organization’s major
users of energy
• Reviewing energy purchasing strategies
• Choices to make sure that the most appropriate energy sources bought at the right prices/time

Energy Efficiency (EE)
What we understand under EE
Energy efficiency means:
- How effectively energy is being used for a given purpose.
Why energy efficiency:
Energy resources are limited
Restricted global fossil energy resources lead to increasing energy costs
More energy efficiency can reduce dependency of energy imports
Increased competitiveness for Indian industries

Key Message
Energy Efficiency and Cleaner Production are not only environmental topics, but a question of competitiveness
Higher energy efficiency leads to improved competitiveness
Better utilisation of resources leads to improved competitiveness
More comprehensive management
Earning More Profits
Resulting in better financial results
Resulting in improved environmental performance

Consumption of Energy by Mobile Charger
2-3 watt/ hr
Average time when Charger is on in a day
3-4 Hrs
Energy wastage by Charger in a day/ year for 1 mobile
10 watt / day 3650Watt/ Annum
Energy wasted by 10% of 10 Cr Mobile Population

Consumption of Energy by AC Remote 2-3 watt/ hr
Consumption of Energy by AC Stabilizer 4-5 watt/ hr
Average time when AC Stabilizer and Remote is without AC in use
5 Hrs / day
Total Energy wasted for 120 days6X 5 X 120 = 3600 watt/ season

Major energy consuming IT equipments
Computer Hardware:• Computer Servers• Computer Desktops• Laptops• Printers• Routers and Switches• Other Networking equipments
• Computers and monitors account for 40-60% of the energy used by office equipment.
• The average computer & monitor use 30% of their energy even while idle.
19.04.2023 Seite 16Page 16
Computer Power Back-up Systems
Uninterruptable Power Supply (UPS) DG Sets
Over sized UPS:UPS systems have poor performance at loads below 25% and efficiency is lost in this process.
DG Sets:The generator should be loaded between 65% to 85%. The loading beyond 85% does not give any extra efficiency, but it decreases engine life.
19.04.2023 Seite 17Page 17
Office Equipments
• Photocopiers• Vending Machines• EPABX Systems• Fax Machines
Photocopiers: It uses the most electricity and do not have to be left on continuously. The equipment not only wastes electricity but also generates heat that leads to a stuffy office or added air conditioning costs.

General Lighting Systems
• Bulbs • Tube Lights• CFLs• LED Lamps
Lighting systems: • Select ballasts and lamps carefully with high power factor
and long-term efficiency in mind. • CFL consumes 1/3rd of energy compared to Indecent Bulb• LED consumes 1/10th of energy compared to Indecent
Bulb

Lighting
Use T-5 (28 W tube light in place of standard T-8 & T-12 tube

Motor DOs
Motors should be operated at rated voltage & balanced supply.
Carry out preventive maintenance and condition monitoring schedule regularly.
Check the RPM as per monitoring schedule.
19.04.2023 Seite 21Page 21
Motor DONTs
Avoid frequent rewinding of motors.
Rewound motors practically have an efficiency loss of upto 5%.
This is mainly due to increase in no load losses.
Hence use such rewound motors on low duty cycle applications only.
19.04.2023 Seite 22Page 22
Motor Dos
Use energy efficient flat belt instead of V-Belt to avoid transmission losses.
Expected saving will be 3 to 5 %.
19.04.2023 Seite 23Page 23
Power Factor Dos
Improve power factor by installing capacitors to reduce KVA demand charges and also line losses within plant.
Carried out Health check up at regularly.

We need to change the MINDSET
• We feel that we are doing BEST
• No need of any HELP
This is the END of further IMPROVEMENT
19.04.2023 Seite 29Page 29
We need to GO with an OPEN MIND
MIND is like a PARACHUTE
It works when it OPENS UP
19.04.2023 Seite 30
Go for New Ideas on Energy Savings with an OPEN MIND
Measure Existing Loads
