Christopher Cooper exhibited at the 2011 Southern Sustainable Agriculture Working Group Conference. The conference drew nearly 500 participants, mostly sustainable and organic farmers and representatives of companies providing and promoting implements for sustainable agriculture. Participants were highly receptive to the Farmers' Handbook for Energy Self-Sufficiency and asked many questions concerning energy efficiency measures they could take that would not require substantial additional outlays. Many participants requested information on how to access additional information about state and federal subsidies for farmers to install energy efficient equipment.
