A renewable energy sculpture is a sculpture that produces power from renewable sources, such as solar, wind, geothermal, hydroelectric or tidal.
Such a sculpture is functionally both a renewable energy generator and an artwork, fulfilling utilitarian, aesthetic, and cultural functions. The idea of renewable energy sculptures has been pioneered by ecofuturist visionaries such as artists Patrice Stellest, Sarah Hall, Julian H. Scaff, Patrick Marold, architects Laurie Chetwood and Nicholas Grimshaw, University of Illinois professor Bil Becket, and collaborations such as the Land Art Generator Initiative. Echoing the philosophy of the environmental art movement as a whole, artists creating renewable energy sculpture believe that the aesthetics of the artworks are inextricably linked to their ecological function.
