1Which of the following is the primary objective of the Energy Conservation Act, 2001, enacted by the Government of India?

A.To restrict the import of crude oil and petroleum products

B.To provide policy framework and promotional measures for efficient use of energy

C.To regulate the tariffs of electricity distribution companies

D.To mandate the shutdown of coal-fired thermal power plants

Explanation: The Energy Conservation Act, 2001 provides the legal and policy framework along with promotional and regulatory measures to facilitate the efficient use of energy and its conservation in India. It also established the Bureau of Energy Efficiency (BEE).

2According to the Energy Conservation Act 2001, who has the authority to specify the qualifications and certification procedures for Certified Energy Managers?

A.State Electricity Regulatory Commission (SERC)

B.Bureau of Energy Efficiency (BEE)

C.Central Electricity Authority (CEA)

D.Ministry of New and Renewable Energy (MNRE)

Explanation: The Bureau of Energy Efficiency (BEE) is the statutory body established under the EC Act, 2001, tasked with specifying the qualifications, certification procedures, and training modules for Certified Energy Managers and Energy Auditors.

3A waste heat recovery system costs ₹8,00,000 to install and yields annual fuel savings of ₹2,50,000. Operating and maintenance costs are ₹50,000 per year. What is the Simple Payback Period (SPP) of this investment?

A.3.2 years

B.4.0 years

C.2.0 years

D.5.0 years

Explanation: Simple Payback Period = Capital Cost / Net Annual Savings. Here, Net Annual Savings = Annual Savings - O&M Cost = ₹2,50,000 - ₹50,000 = ₹2,00,000. Payback = ₹8,00,000 / ₹2,00,000 = 4.0 years.

4If the primary energy supply of India is 900 Mtoe, and the total GDP is ₹200 lakh crore (at constant prices), what is the energy intensity of the economy?

A.4.5 toe per ₹ lakh crore GDP

B.4.5 Mtoe per ₹ lakh crore GDP

C.0.22 toe per ₹ lakh crore GDP

D.2.25 Mtoe per ₹ lakh crore GDP

Explanation: Energy Intensity = Primary Energy Supply / GDP = 900 Mtoe / 200 lakh crore GDP = 4.5 Mtoe per lakh crore GDP. This is the standard unit for expressing national energy intensity.

5What is the equivalent energy value in kilocalories (kcal) of one kilowatt-hour (kWh) of electricity?

A.1,000 kcal

B.860 kcal

C.3,600 kcal

D.4,184 kcal

Explanation: 1 kWh of electricity is exactly equal to 860 kcal of thermal energy. This is a fundamental conversion factor used in energy auditing to compare electrical and thermal energy on a common base.

6In a chemical plant, a process stream enters a reactor with 10% moisture by weight. The total wet feed rate is 2,000 kg/hour. After drying, the moisture content is reduced to 2% by weight. What is the evaporation rate of water in the dryer?

A.160.0 kg/hour

B.163.3 kg/hour

C.180.0 kg/hour

D.156.8 kg/hour

Explanation: Dry mass of feed = 2,000 * (1 - 0.10) = 1,800 kg/hour. This dry mass remains constant after drying. Let W be the final wet product mass. Dry mass in product = W * (1 - 0.02) = 1,800 kg/hour => W = 1,800 / 0.98 = 1,836.7 kg/hour. Water evaporated = Initial mass - Final mass = 2,000 - 1,836.7 = 163.3 kg/hour.

7Under the Perform, Achieve and Trade (PAT) scheme of BEE, what are the tradable instruments issued to Designated Consumers who exceed their energy savings targets?

A.Carbon Credits

B.Energy Saving Certificates (ESCerts)

C.Renewable Energy Certificates (RECs)

D.Efficiency Trade Vouchers (ETVs)

Explanation: Under the PAT scheme, Designated Consumers who achieve energy consumption reductions greater than their targets are issued Energy Saving Certificates (ESCerts). These can be traded on power exchanges with other Designated Consumers who fail to meet their targets.

8In project management, which of the following is defined as the sequence of dependent tasks that determines the shortest possible duration of the project?

A.Gantt Path

B.Critical Path

C.Milestone Chain

D.Slack Line

Explanation: The Critical Path in project management is the longest sequence of dependent tasks that must be completed on time for the project to finish on its due date. Any delay in critical path tasks directly delays the project completion.

9An energy-saving project has a capital cost of ₹10,00,000. It generates annual savings of ₹3,00,000 for 5 years. If the discount rate is 10%, what is the Net Present Value (NPV) of the project? (Given: Cumulative present value factor for 5 years at 10% = 3.791)

A.₹1,37,300

B.₹13,73,000

C.₹5,00,000

D.₹2,37,300

Explanation: NPV = Present Value of Cash Inflows - Initial Investment = (₹3,00,000 * 3.791) - ₹10,00,000 = ₹11,37,300 - ₹10,00,000 = ₹1,37,300. Since NPV is positive, the project is financially viable.

10Which type of energy audit is a quick review to identify energy-saving opportunities, estimate the scope of savings, and determine if a more detailed assessment is needed?

A.Detailed Energy Audit

B.Preliminary Energy Audit

C.Investment-grade Energy Audit

D.Targeted Energy Audit

Explanation: A Preliminary Energy Audit (also known as a walk-through audit) uses existing or easily obtainable data to analyze energy use, identify obvious areas of waste, and determine if a detailed audit is warranted.

Frequently Asked Questions

What is the difference between BEE Energy Manager and Energy Auditor certification?

BEE Certified Energy Managers must pass three written papers (Paper 1, 2, and 3) covering general, thermal, and electrical energy aspects. Certified Energy Auditors must pass those same three papers plus Paper 4, which is an open-book, application-oriented examination focusing on energy performance assessment and case studies.

What is the format of the BEE Energy Manager examination papers?

Each of the three papers (Paper 1, 2, and 3) is a 3-hour written exam carrying 150 marks. The paper contains three sections: Section I has 50 objective MCQs (50 marks), Section II has short descriptive questions (typically 10 questions of 5 marks each = 50 marks), and Section III has long numerical and calculation-based questions (typically 5 questions of 10 marks each = 50 marks).

Are there any calculations on the BEE Energy Manager exam?

Yes. A significant portion of the marks in both the MCQ section and the descriptive sections is dedicated to numerical problems. Common calculations include boiler efficiency (direct and indirect methods), power factor correction, payback period, net present value (NPV), refrigeration COP, pump affinity laws, and air-to-fuel ratios.

What is the passing score and is there negative marking?

Candidates must score at least 50% in each paper (75 marks out of 150) to pass. There is no negative marking in the MCQ section of the exam.
