Answer:
All businesses want to save energy because energy is often a large component of the total cost of running the firm, both as a part of fixed costs (when energy is used for things that are not directly related to production) and variable costs (when energy is used for things that are directly related to production).
Lowering energy costs can result in a significant increase in the profit for the firm, because the lower the energy costs, the more likely it is that sales will be higher than costs, which is the ultimate goal of any business.
