Electrical energy is an important source of power on Iowa farms- over 95 percent of our farms now receive central station electric service. And use of electricity per farm increased about 2.7 times between 1938 and 1947- from 812 to 2,174 kilowatt-hours each year. Electrical equipment used in farm production has increased too. But many possibilities for further expansion still remain.
