Energy is an “Ability of system to perform work ”

Different Forms of Energy are;

Kinetic Energy: Moving water Potential Energy: Oil in barrel Thermal Energy: Heat of an object Chemical Energy: Food when it is cooked Electrical Energy: Electric Stove Sound Energy: Airplane taking off

Energy

AuditAudit means; conducting an official inspection of (a company or its accounts).

Auditing is defined as a systematic and independent examination of data, statements, records, operations and performances (financial or otherwise) of an enterprise for a stated purpose. In any auditing the auditor perceives and recognizes the propositions before him/her for examination, collects evidence, evaluates the same and on this basis formulates his/her judgment which is communicated through his/her audit report.

Definition

Energy Audit

Definition as per Energy Conservation Act, 2001, “the verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption”.

Why the need for energy Audit ?The three top operating expenses are energy (both electrical and thermal), labour and materials.

Energy would emerge as a top ranker for cost reduction

Primary objective of Energy Audit is to determine ways to reduce energy consumption per unit of product output or to lower operating costs

Energy Audit provides a “ bench-mark” (Reference point) for managing energy in the organization

PRIMARY GENERAL DETAILED

• Simple / Quickest audit• Minimal Interview• Major problems to be covered

• Mini audit• Detailed Financial analysis• Expand on preliminary audit

•Comprehensive/Investment grader audit• Expand on General Audit

Types of Energy Audit

Areas of Energy Audit Subject of energy consumption analysis are energy resources consumed in the industrial areas, i.e.

Natural gas Steam Coal Wood, wood chips/pellets Fuels (petrol, oil, propane-butane).....

Areas of Energy Audit Thermal -technical protection of buildings, Heating systems Hot water preparation, Ventilation systems and air-conditioning (buildings and

technology) Electric appliances (administrative and technological incl.

electrical connection, transformation, distribution network, el. switchboards, el. compensation)

Gas or other energy resources consuming appliances (furnaces, cleaning devices,..)

Indoor/outdoor lighting Measurement and regulation

Energy Audit Methodology

Pre-audit presentation

Collection of data information

Measurements and monitoring with instruments.

Computation and in-depth analysis.

Post-audit presentation to discuss the Energy Conservation Opportunities identified by the audit team.

• US Leads - manufacturing, transportation, residential, commercial.

• Heat Waste – Bulb- Light energy

• 7.2 million tons food wastage every year – 1/7

• 500 million plastic bags/ week – 500 years to decompose

• Single leaky tap can waste 5k liters/ year

“Not just what goes in bin is counted as waste”

Energy Wastage

“We strive to reduce emissions & petroleum dependence by being more energy efficient”

Reduction in energy use 28% to 10% within 8 yearsSpain facility was the world’s largest industrial rooftop solar installationReduction in CO2 from 28% to 7% within 8 yearsLeading user of renewable energy in manufacturing sector – “Solar Champion”Half of electricity at California distribution center is powered by sunChevrolet investment - $40 million – carbon reduction projects

Case Study-(General Motors)

– Are there areas that have excessive or unneeded lighting?

– Are you making effective use of available lighting, such as natural sunlight?

– Filters to be checked and replaced when dirty during high usage

– 100 watt bulb to be replaced with LED or CFL bulbs– Make sure all electronics & appliances are plugged in

only if they are in use– Energy star rated electronics & appliance for your next

purchase – Refrigerator unit to be replaced if older than 10 years
