Over the past decades, both agriculture and power systems have faced serious problems, such as the power supply shortage in agriculture, and difficulties of clean energy consumption in the power system. To address and overcome these issues, this paper proposes an idea to combine smart agriculture and clean energy consumption, use surplus clean energy to supply agriculture production, and utilize smart agriculture to support power system with clean energy penetration. A comprehensive review has been conducted to first depict the roadmap of coupling a agriculture-clean energy system, analyze their feasibilities and advantages. The recent technologies and bottlenecks are summarized and evaluated for the development of a combined system consisting of smart agriculture production and clean energy consumption. Several case studies are introduced to explore the mutual benefits of agriculture-clean energy systems in both the energy and food industries.
