To improve the problem in which: selection of a place where a new renewable energy power generation complex is built is difficult and investment attraction by residents is also difficult due to recognition of a low resident participation rate of establishing a new renewable energy power plant and low profitability.SOLUTION: There are provided a device and a method for activating resident participation in a new renewable energy power generation business by a new renewable energy FinTech platform module and a notice of economic efficiency analysis. The device comprises: a new renewable energy FinTech platform module 100; a new renewable energy power generator 200; a new renewable energy power conversion control unit 300; a cloud computing module 400; and a smart economic efficiency analysis simulation module 500. The new renewable energy FinTech platform module jointly purchases an already driven renewable energy generator with local residents as a target, sets a specific identification ID in the residents who jointly purchased the renewable energy generator, shares an amount of daily generated electric quantity, conversion data, and a 1:1 profit dividend, and pays the 1:1 profit dividend into a bank account of a resident himself or herself.SELECTED DRAWING: Figure 1
