If you’ve ever tried to build the business case for a cold-storage upgrade, you’ve heard the sacred question: “Sounds great… how many kWh does it save?” The problem is, your utility doesn’t bill you for average behavior; it bills you for your worst 15 minutes....

The recent sharp increase in the cost of gasoline and electricity affects us every day. Because of this, it is more important than ever to seek out the most efficient technologies. But doing so is not always simple because efficiency is often measured in confusing or...

Quirky nerd alert: fans and pumps are the lungs and heart of industrial facilities. They move air, oxygen, heat, particulates, as well as cool systems and equipment. However, unlike mammals, the lungs and hearts of industrial systems and facilities do not evolve to...

Summer doesn’t break your refrigeration system—it exposes it. When temperatures rise, everything works harder, longer, and often all at once. The result isn’t just higher energy use. It’s a few short demand spikes that quietly determine your electric bill for the...

I’m taking a detour off the industrial efficiency road this week to mention a few things about soaring electricity prices and what’s causing them. Like big oil, big tech is an easy target because trillions of dollars are involved, and who feels sorry for Elon Musk,...

Industrial facilities love a good checklist: swap in premium motors, add variable frequency drives, call it efficiency. But when it comes to motors and drives, that plug-and-play mindset can backfire. In many cases, the difference between real savings and wasted...
