A new look at the use of renewable energy in the agricultural industry

摘要

Nowadays, due to the population growth and the developed economy of most countries, there is increasing need for energy consumption in the industry and agriculture sector. Over the past decades, supplying this energy with fossil fuels has led to environmental pollutions and climate changes. So, it has imposed a lot of cost on different countries. Over the recent decades, many countries have tried to supply energy with renewable energy resources. Due to the significant role of agriculture sector in the countries’ food security and the increased non-petroleum export of oil-producing countries, it is necessary to develop this sector more than in the past. The important issue in this area is focusing on sustainable energy supply. The present research aims to study and identify different technologies that are related to agricultural industries in which, the necessary energy is supplied by renewable resources. The results showed that different types of renewable energies, can be used in devices such as solar desalination system, solar dryer, solar seeder robot, water supply pneumatic pump, wind farm, Solid biofuels, biogas and biodiesel systems, greenhouse heating systems using geothermal water resources, and ground source heat pump. Using these systems can result in the significant reduction of fossil energy consumption, reduction of air pollutants, development of the related jobs, energy security, and the decrease in the social costs of using fossil fuels. These findings can be widely used in designing and management of different energy systems in agricultural industries.
