this series have been exhibited worldwide. In his Art in America review, Dave Coggins wrote that Epstein "grounds his images…in the human condition, combining empathy with sharp social observation, politics with sheer beauty." In an essay for the catalogue Contemporary African Photography from The Walther Collection: Appropriated Landscapes (Steidl, 2011), Brian Wallis wrote, "Epstein has made clear that his intention is neither to illustrate political events nor to create persuasive propaganda. Rather, he raises the more challenging question of how inherently abstract political concepts about the nation and the culture as a whole can be represented photographically…But equally significant is the unique form of documentary storytelling that he has invented in American Power—colorful, sweeping, concerned, intimate, honest." In the New York Times, Martha Schwendener wrote: "What is interesting, beyond the haunting, complicated beauty and precision of these images, is Mr. Epstein's ability to merge what have long been considered opposing terms: photo-conceptualism and so-called documentary photography.

In 2008, Epstein won the Berlin Prize in Arts and Letters from the American Academy in Berlin. Awarded a 6-month residency, he moved to Berlin with his wife and daughter from January–June 2008.

The What Is American Power? project used billboards, transportation posters, and a website to "inspire and educate people about environmental issues." In 2013, The Walker Art Center in Minneapolis commissioned Epstein and cellist Erik Friedlander to create a theatrical performance of American Power, which premiered at the Walker and, in 2015, traveled to the Wexner Center for the Arts in Ohio and The Victoria and Albert Museum in London. Created in collaboration with directors Annie-B Parson and Paul Lazar, this theatrical rendition of Epstein's photographic series combines projected photographs, archival material, video, music, and storytelling. For his recent New York trilogy, New York Arbor and Rocks and Clouds, Epstein photographed the city's trees, rocks, and clouds with an 8x10 view camera and black and white film to depict the interplay between society and nature: "Epstein's trees extend the photographer's longstanding interest in
