5. Saving Your Energy -Means- Reducing Your Costs -Leads to- Protecting the Environment

13. Greenhouse effect? 4% absorbed by clouds. 17% reflected by clouds. 6% reflected by surface. 19% absorbed by water vapor, dust Earth 100% 46% absorbed by ground Earth acts as Solar Collector

14. ENERGY COST REDUCTION Option 1 Electrical Distribution Correction Option 2 Motor Efficiency Improvement Option 3 System Matching and Process optimization Energy Efficient Equipments ~ Energy Efficient Procedures

16. PHASE IMBALANCE Phase imbalance should be within 1% to avoid de-rating of the motor. If the measured line voltages are 403, 406, and 415 volts, the average is 408 volts. VOLTAGE IMBALANCE IS: [(408 – 403) / 408 ] x 100 = 1.225 % Current imbalance creates voltage imbalance

30. HOW TO IMPROVE PF When all the reactive power demand of the system is provided by installed capacitors and reactive power utilization from DISCOs (power source) is zero, we say power factor improvement is 100%, 0.98 Optimum

39. EFFICIENCY COMPARISON Class – 1 Class – 2 Class – 3 Electric Motors

43. SYSTEM MATCHING AND PROCESS OPTIMIZATION Change or reconfigure the process or application so that less input power is required. Downsize the over sized pumps, fans, compressors or other driven loads if possible. Install more efficient mechanical subsystems. Check that coupling, gearbox, fan or pump must be energy efficient. Electric Motors

44. PROCESS OPTIMIZATION Reducing circulation fan speed from 80% to 60%; power consumption was reduced by 54 %. REGULATE FAN SPEEDS WITH TEMPERATURE Unwise use of machines Average Speed Reduction 10% 20% 30% 40% 50% 60% Potential Energy Savings 22% 44% 61% 73% 83% 91%

48. ENERGY COST COMPARISON Lighting System

49. ENERGY SAVING IN LIGHTING T-12 lighting system up gradation to T-8 = (kWh saved/year)(Rs./kWh ) = (20,000 kWh saved/year)(8 Rs./kWh ) = 160,000 Rs. = (# fixtures) [(40 watts-T12)—(36 watts-T8 )] = (1000) [( 40 watts )-( 36 watts )] = 4 kW = (kW savings)(Annual Operating Hours) = (4 kW)(8000 hours/year) = 32,000. kWh/year KW Savings KWh Savings Rs. Savings per year Lighting System

52. Hand operated machines; like Generators Water pumps Washing machines Flour grinding machines etc… THINK ABOUT IT . World population of 6B, increasing to perhaps 10B by 2050 FUTURE BUSINESS???
