Dr. Shahzeen Attari's research highlights public perceptions of energy consumption, noting a preference for curtailment over efficiency as the primary method for reduction—a view contrary to expert findings.

Her work indicates that the public tends to slightly overestimate energy costs for low-energy behaviors while significantly underestimating them for high-energy behaviors. Attari also identified factors correlating with the accuracy of these predictions.

These findings were presented at the Garrison Institute's Climate, Buildings and Behavior Symposium in May 2010.

John Fullerton, founder of the Capital Institute, transitioned from Wall Street to become a sustainability advocate. Influenced by E.F. Schumacher's "Small is Beautiful," he collaborated with Allan Savory, founder of Holistic Management, to restore grasslands and return carbon to the soil. This work was highlighted in an October 2010 interview.

The Capital Institute seeks to harness capital for a just, resilient, and sustainable economic system. The Savory Institute restores global grasslands through Holistic Management. The Schumacher Society, founded in 1980, promotes strong local economies linking people, land, and community.
