We are proposing a new decentralized power-grid prototype for Green New Deal, which is a mixed-use RED(Reverse Electrodialysis) electricity power plant to replace the previous program with public works, including farming, laboratory and harbor, to conceive the idea of “post-coalism”. The architecture form will be flexible to adapt to the environmental change. In addition, in order to adapt the contaminated site, a series of bioremediation processes will occur in an architectural manner which creates a new form of nature on the plant co-existing site.
