Fuel conservation. Home insulation conserves fuel. Every homeowner can get behind his government's efforts to conserve fuel whether he heats his home with oil or coal, and both are strategically important. Fuel savings can be effected by keeping temperatures at reasonable levels, closing off unused rooms, and insulating in various ways. Windows can be weather stripped. Conservation of fuel will help release railroad and other transportation facilities for the movement of fighting materials. Sourced from the Library of Congress.
