The amount of energy that these and other life sciences sectors use must be reevaluated by businesses. The SEC value, or specific energy consumption, can assist in determining how much energy a firm consumes and how efficiently it is managed. Analysis of how a company uses coal, gas, air, and water, and other resources must be done properly.
