When calculating savings in energy cost from using natural gas appliances and considering conservation and efficiency efforts, some analysts simply multiply the average cost per unit of energy times the energy savings. This method of determination is inappropriate because only a part of the natural gas energy cost should be considered in this calculation. The marginal costs should be considered when calculating the impact of conservation efforts, which tend to happen, at the margin of user consumption.
The Gas Technology Institute conducted a technical and economic analysis of the DOE Furnace Efficiency Rule for AGA to evaluate the impact of the proposed 92 percent AFUE minimum furnace efficiency requirements.
Because safety is the natural gas industry's top priority, the industry spends more than $6 billion each year to maintain the system's excellent safety record. Serious accidents on the natural gas delivery system are rare, but the natural gas industry is dedicated to making them obsolete.
