The good news is that a number of companies in both goods and services in dustries have started developing new products that are based on environmnentally sound practices. For example, in recent years a number of automobile models,such as the Toyota Prius, that use electric and gasoline hybrid engines have appeared in the marketplace. The hybrid engines regenerate power when the car is decelerated or goes down a hill or when the driver applies the brakes. The regen erated power is used to charge a high capacity battery. The battery power is used when it is inefficient to use the gasoline engine (e.g., when the car is waiting at a stoplight). Therefore, the car uses less gasoline, produces less exhaust, and re leases fewer greenhouse gases into the atmosphere. Another example of environmentally friendly design is the use of paper cups and plates (often partially made from recycled paper) instead of Styrofoam at quick service restaurants.
