Since the early days of American history, so-called utopian communities have been a defining feature of our cultural landscape. Photographer Joel Sternfeld has captured 60 of them in his new book, "Sweet Earth". A common theme in these societies is harmony with nature, and many also boast noteworthy eco-friendly features. In this series of stories, we'll visit North Carolina, New Mexico, Massachusetts, Illinois, New Mexico, South Dakota, and Tennessee, and learn about their founders’ visions.

Arcadia Cohousing, Carrboro, North Carolina, April 2005

The home of Giles Blunden is independent of the public power grid. The solar panels visible on his roof provide electricity and heat water. Blunden is the chief architect and founder of Arcadia Homes, a sustainable cohousing community in which all thirty-three residences have passive solar design (non-mechanical solar heating achieved through site selection and large south-facing windows) and some active solar elements (collecting the sun’s rays by appropriate technology to provide heat, mechanical power or electricity).

In addition to its solar features, Arcadia is a pedestrian-friendly community that preserved nine acres of climax hardwood forest when it was built, by clustering houses on land covered with secondary-growth pine trees. The distinctive architecture of the community derives from vernacular local millhouse structures.

In 2003 the share of all electricity produced by solar cell technology in the US was 0.07 percent—though as far back as 1979 President Jimmy Carter announced (at a press conference held on the White House roof) the goal of bringing sun, wind and other renewable resources-generated electricity to twenty percent of the US total by the year 2000. In contrast, Japan, where fossil fuels are much more expensive, generated four times the amount of solar electricity produced in the US.

As solar power approaches a cost of $2 per watt, it is becoming less expensive than commercial power. Thirty-eight states, including North Carolina, have enacted “net metering” laws that require utilities to connect residential solar panels into the grid and to compensate homeowners for any excess electricity they produce.
