‘Smart’ Greenhouse Lighting Saves Electricity

A study by University of Georgia researchers showed that a greenhouse lighting system that optimized lighting based on a predictive model saved farmers 33% on electric lighting costs during the spring. The system generates the most savings while the sun is shining. Researchers say it could save even more money when variable energy costs are considered, as well. “The electricity used for the lights is anywhere from 10% to 30% of the cost of running a greenhouse,” professor Marc Van Iersel said. “Our research began with the idea that, if we can reduce this cost, we can very quickly have an impact on the efficiency and sustainability of greenhouses.”
