An annual wind power conference in July is expanding this year to include other renewable energies, including solar and alternative fuels, and educational workshops to help homeowners and small businesses use the technologies. 

WIndiana/Indiana Renewable Energy Conference, July 20-21 at the Indiana Convention Center in Indianapolis, will bring together experts from industry, academia and government to address key issues in wind power. The conference is organized by the Indiana Office of Energy Development and the Energy Center at Purdue University's Discovery Park.
