When the planned community of Greenbelt, Maryland was built in 1936 and then the defense housing in 1941, the kitchens were equipped with 21 inch electric ranges with three surface units. Thank God there was no natural gas service to the town which was in the middle of nowhere. Everyone cooked electrically, even the industrial kitchens in the schools. Oil and coal fired the boilers for heating and hot water until the 1980s when the cost of oil grew to be too burdensome. A huge program replaced the metal frame casement windows, decommissioned the boilers,Insulated the attics, heavied up the electrical service to each unit and put in individual water heaters and baseboard electrical heat.
