The cultivation of plants in an automatic closed-system greenhouse develops the cultivation for precision agriculture. Growing plants in microclimate-controlled greenhouses to suit the plants growth makes the plants grow with quality and quantity as needed. This article describes energy conservation guidelines in a closed-system greenhouse, which has microclimate controls in the greenhouse using cooling techniques. Electric motors are a key component in a microclimate-controlled system, which is regarded as system with significant electrical machinery with the potential to conserve energy in a closed-system greenhouse. The energy conservation guidelines are as follows: (1) Energy saving with electric motors, (2) Energy saving with electric motor control systems, and (3) Energy management in closed-system greenhouses. The energy conservation helps to reduce energy consumption, reduce electrical costs, reduce energy imports and reduce global warming as well.
