According to Central Connecticut State University’s The Recorder Online, the Toyota Prius causes more pollution than a Hummer. Most of this is due to the materials used in its construction. Also, it takes more energy to create and run one of these vehicles than a conventional car.
What is not addressed in the article is the question: What do you do with the Prius batteries once they wear out? Batteries can only be charged and recharged so many times, and the chemicals used in them will degrade over time. And some of the chemicals used are pretty nasty. And let’s not forget the amount of energy that will be required to recycle the batteries as well.
I have my own ideas on what an economically-friendly personal transportation system could be in the future, and the technologies are being developed or are already here. But that’s a post for a later time.
In the meantime, remember that the hype on eco-friendly cars, global warming, and carbon-credits is not what it is cracked up to be. More than ever, I believe that there are political agendas being addressed instead of real problems.
