Greenhouse Energy

In an industry with declining profit margins, and with volatile fuel prices, there is increasing need to grow greenhouse crops in an energy-efficient manner.  The best approach is to attack this industry threat using a variety of strategies.  In collaboration with horticulturists, agricultural economists, and agricultural engineers, we have developed this web site to provide summary information on production strategies and technologies that greenhouse growers can use to consume less energy and improve production efficiency.  Please click on the links above for more information on each topic.  Additional resources are below.

Greenhouse Energy Conservation Strategies

This 16-page summary, in pdf format, presents 13 production strategies and technologies that greenhouse growers can use to reduce energy consumption and improve greenhouse production efficiency. Topics include:

  • Energy-efficient lighting
  • Managing greenhouse temperature
  • Reducing air leaks
  • Retractable curtains
  • Maintaining heating equipment
  • Horizontal air flow fans
  • Efficient ventilation systems

Although many of these concepts can apply to virtually any greenhouse-grown crop, the focus is on the production of floriculture crops in controlled greenhouse environments located in temperate climates. Written by Erik Runkle (Michigan State Univ.) and A.J. Both (Rutgers Univ.).

 

We thank the Michigan Greenhouse Growers Council, who received a grant from the USDA Rural Development Office to help subsidize the costs of developing this energy resource.  In addition, Project GREEEN has provided funding to researchers at Michigan State University to generate research-based information on how to optimize temperature and light to increase greenhouse cropping efficiency and thus reduce energy consumption.

  • Plant temperature under greenhouse curtains

    Published on October 17, 2012
    Retractable energy curtains save energy costs by serving as an insulative layer and reducing the amount of space heated. In addition, plants under the curtains can be at least a few degrees warmer than plants not under a curtain.

  • Environmental & genetic approaches to lower greenhouse heating costs

    Published on March 22, 2012
    To lower energy costs for greenhouse heating, we have taken two approaches: to optimize greenhouse temperature on a species- and seasonal-basis, and to develop genetic resources to help facilitate the breeding of crops that flower earlier.
