There are few actions we take that could have a greater impact of our person greenhouse gas emissions footprint that the decision we make when buying a car. Despite the claims of the fossil fuel apologists that have entered the public arena that electric cars are no better than conventional vehicles because of the emissions associated with producing and disposing of the vehicle (especially the battery), reputable independent full life cycle analyses reveal that electric vehicles are definitely superior. A study by the European Energy Agency and a slightly narrower and recent study by Vancouver (BC) add more information. Whether electric vehicles receive their electricity from renewable sources (obviously optimal), or from coal-fired power plants, the greater efficiency of electric versus gasoline engines makes the electric option much more environmentally rational.
Climatic conditions will influence the efficiency of the vehicle, whether electric, hybrid of internal combustion engine but overall, the electric vehicle will always be the best choice for reducing emissions.
