In conclusion, we have shown that the faster belt speed and the shorter skirt has an energy efficiency of 35% when compared with a fully-skirted slower conveyor. Here’s how to calculate the difference in power consumption: We simply subtract 79,103 kW-hrs/yr from 122,200 kW-hrs/yr to derive an answer of 43,097 kW-hrs/yr. Dividing that by 122,200
