A discussion of (1) advantages and problems in substituting natural gas for electricity, especially for residential space heating and cooling and water heaters; (2) possibilities and problems of producing and using synthetic gas; and (3) ways of curtailing energy consumption. Major points are: Gas, natural or synthetic, will be in very short supply for the next 10 years. Even complete deregulation of interstate gas prices will not increase domestic production. Off-shore reserves will make no significant contribution for at least 10 years. Transporting liquefied natural gas entails unresolved hazards. Production of synthetic gas from coal will take a few years, and generation of methane from organic material is still in the future. Some effective measures for conserving energy consumption might be to double prices on all forms of energy immediately; increase factory installed insulation on water heaters; reduce automobile weight; transport freight by railroads and waterways; and eliminate pilot lights on new gas appliances. 25 pp.
