Profitability is the rate at which profits are generated from an investment.

 Because energy conservation lowers operating costs, it raises profits - the difference between revenue and costs. Because energy costs are fuel purchases and utility expenses, it only helps all stakeholders such as owners and employees.

 Energy conservation investment costs are very low. When energy conservation is applied to maintenance costs are negligible, while these improved practices extend the life of existing equipment - thus lowering other investment costs.
