Page 7 MANUFACTURED GAS IN THE HOME
A comprehensive study of the problem must make irresistible the conclusions that -- a. Electric cooking is a luxury for a limited few for whom reduced rates – except for quantity used – can not be justified in social justice and nondiscrimination to all consumers. b. Electric heating of houses would be a gross waste rather than a conservation of fuel resources and so prohibitive in cost to users as to be beyond all consideration. Therefore gas and not electricity must be depended upon for the cooking and house-heating service of the urban public for the future and the manufactured-gas industry must meet this increasing public- service obligation. The possibilities of hydroelectric power are greatly overrated by the public generally. Hydroelectric power is not of itself, and under all conditions, even when the water power is widely available, more economical and cheaper than steam power. Water-power development can not, therefore, substantially change the electric cost situation. HOW ELECTRIC COOKING AND HEATING WOULD WASTE COAL.[6]
A week's series of 21 meals, all of different menus, each for five people, were cooked with electricity. Exactly the same meals were then cooked with manufactured gas. The total weekly fuel consumptions for the 21 meals were as follows:[7]
Electricity ------------------------------------------------------------------- 44kw. h.
Manufactured Gas (515 B. t. u.) ------------------------------ 532 cu. ft.
Pounds of coal.
Taking the average coal consumption – allowing for transmission losses and low load factor conditions at 4 pounds to the kilowatt hour as delivered at the consumer's appliance – the electric
range requires 4 times 44 -------------------------------------------------------------- 176
On the basis of complete gasification and 40,000 cubic feet of manufactured gas to the ton of coal, or 20 cubic feet of gas to the pound of coal,
manufactured gas requires 532 divided by 20 ---------------------------------- 27
Therefore about 6 pounds of coal would be required for electric cooking to 1 pound for manufactured-gas cooking. The effect of the general use of electricity for cooking and heating on the Nation's fuel problem is shown in the following: Million tons of coal.
Total coal mined in the United States ----------------------------------- 640
Total coal required to generate electricity for cooking and heating service to 6 million homes
in the United States ---------------------------------------------------------------- 750
Total coal required to make manufactured gas for heating service to 6 million homes in the
United States --------------------------------------------------------------------------- 82
Coal now used by all domestic consumers of coal
in the United States --------------------------------------------------------------- 106
