UNIT ONE
Test New Areas of Gas Consumption
[1] New technologies introduce the possibility of whole new awras of gas consumption.In the history of gas industry ,technical change has from time to time led to important shifts inthe main sectors of consumption-the most obvious of which have been the changes in the princpal uses of gas from linhting to cooking and from ccking.Over a 25 yeas period ,such as the one covered in this study,it is possible that some new use of natural gas ,based on a novel technical development,could have an appreciable impact on the domand for gas .It is difficult or impossible to predict with any degree of certainty of demand.It is possible,however,to identify areas of current reseauch and technical interest which may offer some potential for the future.
