Are energy meters like birdhouses or like screws?

It occurred to me that meters relate to energy monitoring in the same way as screws relate to birdhouses. How is that? Some manufacturing plants start energy management from installation of meters. Too often the process ends with meters too. However costly, this result is predictable. I will explain why on an example of [...]

#10. Energy audit saved $125,000 CAPEX

A common belief is that if plant is equipped with efficient machines it runs efficiently. Unfortunately, this is not always true. Efficiency of components does not equate to efficiency of the whole plant. Common reason for utility waste by efficient machines: Misuse: compressed air used instead of blowers or for cooling, oversized motors, excessive [...]

#6. 6 beliefs about energy efficiency busted by energy audits

We often hear: "Our plant runs at top energy efficiency because we use these procedures and settings and our efficient equipment is fully operational." Just how often is this true? With all due respect to maintenance and operational staff, recommendations of a proper energy audit are based on direct observation of operations and lots [...]

#4. Energy savings at manufacturing plant beyond LED, VFD and idling

Complex energy audit does not look at energy alone. It considers how energy use affects core business - production, quality, scrap, employee productivity.
