Abstract: Under the background of dual carbon goal and rural revitalization strategy, courtyard circular economy has become one of the main modes of agricultural development, and its energy utilization mode and energy flow research are still in its infancy. Firstly, based on the production scenario, the design is suitable for the local courtyard circular economy energy supply mode. Secondly, based on the energy supply and consumption mode, this paper studies the zero-carbon operation under the courtyard circular economy mode, and proposes a carbon emission calculation method under the model. Finally, the feasibility of zero-carbon operation of the circular economy energy supply mode of the courtyard is verified by an example.
