The dominant energy sources on conventional farms in the developed world are diesel oil (to power tractors and other self-propelled equipment) and electricity (to provide light, heat and refrigeration; and to power electric motors to run milking machines, animal feeding systems, ventilation fans, water supply and irrigation systems).
Despite their differences in natural resources, Japan, European countries, and the United States managed to expand their agricultural output by up to 1.7 percent a year. Japan and the continental European countries achieved their rapid growth because yields (output per hectare of arable land) grew at about 1.5 percent a year, or roughly twice as fast as in the United States.
