But it doesn’t have to be a difficult task. There are quick ways to find what’s wasting energy and identify potential cost saving opportunities.
When energy was less expensive, manufacturers didn’t have to primarily focus on energy efficiency. Neither did homeowners, that 10-year-old refrigerator consumes 20% more energy than a new one.
Identifying energy-saving opportunities in your plant can be simple and quick. In many cases, money and energy are literally flying out an open window if you are not paying attention to the process. A few easy opportunities to save:
1. Turning off lights/machinery when not in use
2. Fixing air compressor leaks
3. Reclaiming waste heat
Just like these easy steps, processes that are not too complex and energy intensive are due for an overhaul.
In some cases where energy is such a small percentage of overall costs, you may think this seems like small savings with big efforts. But it is worth it, especially with the increase of prices and regulatory pressures. If you’re evaluating your production and how you use energy to meet government regulations, then use that time as a chance to look at all areas, big and small.
Your air compressor system has leaks. This may be frustrating, but does it affect your manufacturing process? Maybe not. But, according to the US Department of Energy, leaks typically make up 20-30% of the total compressed air load in plants without maintenance programs.
Or does your warehouse need to be at a certain temperature? What happens if you bump the thermostat up (or down) a few degrees? What are the savings if you shift part of your operations to off-peak periods?
Small savings do add up and minimal efforts can make a big difference, so take the time to see where you can save.
