Agriculture in its evolution, particularly in the last 20-30 years, marked increases in production and increases energy consumption. Compared with the national economy in general or with industry, energy consumption in agriculture is reduced. There was an alarming situation in the energy needs of agriculture, due to the fact that some forms of energy, direct or embedded in the materials used for the flow of technology, become pollutants in some cases heavily polluting. Energy use in conventional agricultural production can be reduced because it continually receives free, unconventional energy in various forms, from the Sun and soil.
