Three major categories of energy utilization coefficients were calculated and reported. Direct energy refers to the gasoline, diesel fuel, electricity, natural gas, etc. consumed in the production activity itself and in the refining, or gen eration, and delivery of this direct energy. For example, the fuel used for ground preparation, seeding, pumping irrigation water, cultural operations, and harvesting are considered as direct energy requirements for crops. The non-direct energy requirements are subdivided into two categories.

Lee ABSTRACT—Data are presented on the quantities of various forms of energy used directly in the production of six important agricultural commodities in Washington State. Indirect energy requirements (energy used in the production of inputs into agriculture) were calculated for four sectors of Washington State agriculture, using an input-output matrix.
