In the age of global climate change, people are becoming more and more aware of their carbon footprints and taking measures to reduce them. Hybrid cars have become extremely popular, and some cars claim to be 'zero emission vehicles.' However, even if a vehicle does not create pollution, it is very likely that the source of the energy that is powering the vehicle does.
The Nissan Leaf and Chevrolet Volt, two electric vehicles that are touted to become real game changers in the auto industry, are slated for release at the end of the year. These vehicles offer great promise in their efficiency, emissions, and relatively affordable price point.
But neither avoid the nagging question: If the ultimate power source for an electric vehicle is coal or natural gas, how is the vehicle truly zero emissions?
The ultimate in eco-conscious driving is an evolving concept, but a framework is emerging that appears to be a sustainable benchmark. A purely electric vehicle that receives its power from a renewable electrical source such as solar, wind, or hydroelectricity, could very well be the most environmentally responsible driving opportunity available.
