Measures to improve energy efficiency and reduce greenhouse emissions are often opportunities to cut costs and improve services as well.

Also it's easier to sell some projects first as improved services, with energy and cost savings as bonuses.

Many opportunities to improve energy efficiency are overlooked because their financial attractiveness is hidden when you

• don't consider all the costs and base decisions on purchase price alone
• don't consider all the benefits
• expect investments to pay for themselves too quickly
• ignore the low risk of investments in waste and energy minimisation which makes investments with even a moderate return very attractive.
