According to the recently unveiled estimations, fossil fuel reserves would have last only for a lifetime of about 100 years. However, the period varies depending on the type of fuel reserves. Irrespective of the ostensible durability of non-renewable resources, their originated environmental pollutions will soon force the policy makers exert some restrictions on their application and also to assign promotions to encourage the application of environmentally-friendly energy sources. The challenge of global warming in recent years and continuation of this situation in the years ahead underlie irreparable effects on the life status on the planet. Hence, to deal with these detrimental environmental impacts, optimization in energy consumption and utilization of renewable (green) energy systems can be regarded as a priority. Green energy resources will be gradually considered as one of the most suited options/ best alternatives to fossil fuels that in addition to being permanent and interminable have much fewer contaminant features. Solar, wind, water, sea waves and tides, biomass and geothermal resources are of the most significant green energy resources that have been identified so far, and have a huge potential to be applied pervasively in the agriculture industry. Key words: clean and sustainable agriculture, environment, green energy, renewable systems 1. Introduction Undoubtedly, energy itself can be considered as one the fundamental factors involved in economic growth of the more progressed societies [1]. Commercial use of energy is an essential condition for development. It is not surprising that the countries with less interest rate of non-renewable sources of energy are among the poor countries. Nonetheless, commercial production and/or consumption of energy by itself brings challenges such as climate change, greenhouse effects, global warming, the downfall of acidic rains, and distribution of carcinogens, fumes, and other pollutants in the environment [2]. Increasing demand for energy requires a balanced and long-term strategy that covers both the different resources and regional specific solutions like to benefitting more on alternative energy sources, optimizing potential for energy efficiency, and encouraging the private sector to exploit clean technologies. Currently, the majority of energy consumed in the word is supplied by fossil fuels. The combustion of such non-renewable fuels, trigger the massive entrance of SO2 (Sulfur dioxide) and NO2 (Nitrogen dioxide), CO (Carbon monoxide), and
