Cover Story: Irrigated agriculture in many areas around the world relies heavily on groundwater resources. Depending on the depth of this resource and the irrigation demand, significant amounts of energy may be required for pumping the water. Identifying the efficiency of irrigation pumping and its impact on energy costs and greenhouse gas emissions can assist with moving towards sustainable agriculture. A study was conducted in the central and Panhandle regions of Oklahoma, where irrigation is supplied from two different aquifers. The results showed that the majority of pumping plants were operating at efficiencies below achievable recommended levels. The emissions were similar between natural gas and electricity powered plants when normalized based on irrigated area and total dynamic head. Improving efficiencies could result in 19-34% reductions in energy use and 20-52% reductions in emissions. View this paper
