Air pollution, water pollution, global warming, and ozone depletion are some of the issues we confront every day that mirror the outcomes of our activities. Satti Swami Reddy and Kola Siva Tharun, (2013) said the cars we drive emit exhaust gas, whose harmful components affects the environment which causes acid rain and global warming. Carbon dioxide is one of the main greenhouse gas which is emitted to the thin air through human activities through the burning of fossil fills such as coal, natural gas and oil for energy and transportation. Due to high environmental concerns, various countries have been attempting to try resolving these problems and one the outcome is the invention of hybrid cars, which can help contribute to save the environment by giving off less emission. Yost (2006) said the innovation of hybrid cars have helped to decrease gas emission especially carbon dioxide considerably to …show more content…
A promise development in the hybrid arena is the concept of a plug in hybrid. Essentially it provides all the advantages of a hybrid car, but increases its electric range by allowing it to plug into the electric grid and further reducing fuel consumption. This will especially be efficient in a city driving setting where operating at short distances at lower speeds will allow the vehicle to run in electric mode a majority of the time and qualify it as ZEV (zero-emission-vehicle) in cities (Kang,
