Abstract

Today's energy-intensive human life, caused investigating different sources of energy supply. It is extremely important to use renewable energy sources to generate scattered electricity, due to the high cost of electricity transmission lines, and also necessity of pollution reduction and environmental protection. One of the sustainable energy resources is biomass, which cow dung is a subset of it. In this study, the number of the cows in the Mashhad County were estimated. Also, the electricity consumption in agricultural sector of Mashhad County was estimated for the year 2035. Finally, according to the available energy from cow dung, the possible energy supply was calculated for agricultural sector of the region. Electricity production from cow dung and energy needed in agricultural sector for Mashhad was estimated to be 6797 and 12342019 MWh, in 2035, respectively. Therefore, the amount of energy from cow dung is less than 0.1 percent of the energy needed. This source of energy (cow dung) is recommended for producing thermal use or scattered electricity. The use of other sources of biomass could be a solution to provide some part of energy demand from clean resources.
