Increasing Resource Efficiency
There are two ways to reduce the material consumption per unit of service, the material input (MI) of the product can be reduced or amount of service units (S) can be increased. Material input in the production phase can be reduced by using less energy or raw materials. Also transport chains can be rationalized. In the use phase the material input per unit of service can be reduced when amount of service produced is increased. For instance in case of a newspaper the material input can be reduced by using recycled paper instead of primary. Material input per reader decreases when the same paper is shared with several persons. High quality products and availability of spares potentially increase the service life of the product. When the service life of a product is increased, the material consumption per unit of time decreases. Usually services like car sharing also help to reduce MIPS values since fewer products are needed to produce the service for greater number of people.

Famous quotes containing the words increasing, resource and/or efficiency:
“As men get on in life, they acquire a love for sincerity, and somewhat less solicitude to be lulled or amused. In the progress of the character, there is an increasing faith in the moral sentiment, and a decreasing faith in propositions.”
—Ralph Waldo Emerson (1803–1882)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
