Renewable energy has the advantages of environmental friendliness and recyclability.Comprehensive utilization of renewable energy is an inevitable trend in the development of green container port construction.This paper firstly presents a simulation-based method to quantify the energy consumption of loading and unloading production in ports.Then,the environmental and economic benefits of renewable energy to replace the traditional energy is quantified with the environmental and economic benefit calculation method.Finally,taking wind power generation as an example,this paper obtains and analyzes the environmental and economic benefits of the energy replacement for trucks,quay cranes and yard cranes.
