Save with a conversion to Natural Gas             [back]

Commercial buildings have a large appetite for energy and account for 18 percent of total U.S. energy consumption. In a typical office building, energy use accounts for 30 percent of operating costs, the largest single category of controllable costs.

Natural gas will costs less to use in 2009 than any other major energy source according to the Department of Energy’s Office of Energy Efficiency and Renewable Energy.

According to the DOE, 1 million British thermal units (Btus) of natural gas will cost an estimated $11.12 this year, while the equivalent amount of electricity will cost roughly three times as much $33.41.

Below is a look at fuel cost comparisons. For more information on how to save money and energy in your commercial building contact us today at 1-888-697-5377.

WATER HEATER ANALYSIS SUMMARY: The water heater analysis is based on providing the equivalent First Hour Rating (FHR) based on national average energy usage and the 2009 energy costs as defined by DOE. A natural gas fired 40-gallon and an electric 50-gallon, both conventional storage type, are chosen on this basis. The natural gas water heater would provide the lowest operating cost water heating option.
