This document discusses green cars and their benefits. It defines green cars as vehicles that use alternative fuel sources like biodiesel, solar, or electricity rather than gasoline. Green cars decrease greenhouse gases, are cheaper to run and maintain, provide renewable energy sources, and reduce health and environmental risks. Hybrid vehicles, like the Toyota Prius, combine a gas engine with an electric motor to increase fuel efficiency. The Prius is one of the most fuel efficient and popular green car models. Electric vehicles, such as the Nissan Leaf, run solely on electricity from batteries and produce no direct emissions.
