Importance of alternative energy has been increasing due to environmental issues and lack of fossil fuels. In addition, heating cost that occupies from 30 to 40 % of the total production cost in Korean protected cultivation needs to be reduced for profitability and global competition. Therefore, this study was conducted to develop energy model and regional resource for recycling of resource in greenhouse. Based on the results of the theoretical and statistical investigations, energy model of regional resource was developed. This results was shown with a new standard 2,000 heads of pigs. Livestock manure was originated 8.6 kg/day/one head, and the average biogas yield was 1.23 Nm3/day occurred. The biogas reactor and engine showed that scale of 300 m3 was 25kW respectively. Agricultural and Forest Residual-products Biomass quantity in heating road of 200,000kcal/h were 1,224 kg, 912 kg respectively.
