Energy is a significant operational expense for greenhouse businesses, second only to labor costs. To reduce energy usage and expenses, greenhouse growers can implement various energy conservation strategies. These strategies include the use of retractable energy curtains, high-efficiency heaters, energy-efficient lighting, and optimal management of the growing environment.
At the start of each season, greenhouse growers should consider implementing energy-saving practices or smaller projects such as managing growing temperatures, installing horizontal airflow fans, sealing leaks, and maintaining heating systems. During the off-season, growers often focus on larger energy-efficient projects that require substantial capital investment or construction, such as installing energy curtains, root zone heating systems, and large lighting installations. Some practices and equipment, like energy curtains, are more practical and provide a better return on investment for medium to large growers who operate during the coldest and darkest months of the year.
To assess their energy efficiencies and practices compared to other growers of similar size in Michigan, greenhouse businesses can use the Greenhouse Energy Index Decision Support Tool developed by Michigan State University Extension. This tool helps businesses evaluate their energy practices and projects. Program manager Aluel Go of Michigan Farm Energy will discuss this tool during a virtual event on January 22, 2025, at 10 a.m. Participants will have the opportunity to confidentially compare their energy metrics with benchmarks established by previous energy audits conducted in Michigan.
The Greenhouse Energy Index Decision Support Tool assists growers in determining their business’s energy efficiency levels and how implementing common energy conservation measures can impact energy usage. It helps prioritize energy efficiency projects and assess how energy efficiency compares to similar-sized operations in Michigan.
While the event is open to out-of-state growers, those in climates similar to Michigan will benefit the most as the standards were developed based on Michigan-based farm energy audits. While volunteers may provide their metrics as examples, participants are not required to share their business numbers with others.
