15 2014 RESPONDENTS Forecast Outlook Forecast Accuracy Forecast Outlook survey represent 1,730 Billion kwh of electric sales and 1,050 BCF of natural gas in North America. Forecast Accuracy survey represent 1,930 Billion kwh of electric sales and 1,925 BCF of natural gas in North America Weights are approximate energy weights used in the weighted average calculations Other Electric include ISO and Retail Suppliers. These results are not included in regional or national weighted results
