Study Design

The U.S. Energy Research survey was conducted between Feb. 9, 2021, and March 3, 2021, among 350 energy decision-makers at organizations with 1,000 or more employees across the United States. Both telephone and online survey methodologies were employed.

Margin of Error = +/- 5.2 Percentage Points Sample = 350 Energy Decision-Makers at Companies With 1,000 or more Employees Across the U.S.

Results of any sample are subject to sampling variation. The magnitude of the variation is measurable and is affected by the number of interviews and the level of the percentages expressing the results. In this particular study, the chances are 95 in 100 that a survey result does not vary, plus or minus, by more than 5.2 percentage points from the result that would be obtained if interviews had been conducted with all personas in the universe represented by the sample. The margin of error for any subgroups will be slightly higher.

About the study sample

All survey respondents work at companies with at least 1,000 employees in the United States, and around 28 percent had more than 2,000 employees. The survey reached energy decision-makers in a wide range of industries, with the largest groups in IT, telecommunications and media (22 percent) and manufacturing (19 percent). Only 6 percent of respondents work within the energy industry.

Most respondents (86 percent) worked at companies with multiple locations, with 3 in 5 (61 percent) at companies with fewer than 10 locations. Half of all respondents worked in companies whose operations were fully within the United States and an additional 28 percent had fewer than 10 international locations.

Demographically, about three-quarters of respondents identified as male (77 percent), and the age of respondents was widely distributed, with almost half between 35 and 44 years old (48 percent).
