انرژی های تجدید پذیر، مدل های تجاری و رشد محلی

This paper describes a practical example of the implementation of a biogas plant at a farm in the Madonie Mountain area of Sicily, Italy; by estimating the costs and revenues that will result from its management, we demonstrate how the bioenergy sector presents a great opportunity for farm supplementary income. Through cost-benefit analysis, we show that the investment is cost-effective both in terms of Net Present Value (NPV) and Internal Rate of Return (IRR).
