Though the initial cost of purchase of EV is high and may range anywhere from $ 35,430 (Nissan Leaf model) or $ 40,000 to $ 50,000 (for BMW models) depending on the manufacturer and the model; the cost may come down in future, however when and if the demand for EVs increases making the cost of manufacture and maintenance more economical. As Lavelle explains that cost of operation of an EV is considerably lesser than that of a conventional vehicle, as electricity is available cheap in most part of the world and fuel efficiency also helps bring down the cost per mile significantly; maintenance costs are also reduced due to oil-free combustion system.
With all these benefits, EVs definitely seem to hold the key to future of transportation systems globally. However, many do not agree. Eco-friendliness of EVs –A Myth? “A major reason why EVs are gaining popularity is their claim to reduce greenhouse gas (GHG) emissions and to be more beneficial from the environment” (Miret p.1), however, deeper investigations prove otherwise. Critics of EVs dispute their eco-friendliness because, although EVs may have no tailpiece emissions, the process that manufactures the batteries of EVs and other factors contribute more to carbon emissions into the atmosphere than do emissions from conventional vehicles.
Assessing the environmental benefits of EVs, therefore, is rather complicated observes Miret (p. 1). Comparing the GHG of internal combustion engine vehicles or ICEVs and EVs, Miret observes that, “EVs actually increased GHG emission by 17% when compared to ICEVs and 27% for diesel ICEVs.” Bjorn Lomborg of the Wall Street Journal echoes the above and cites the 2012 comprehensive life-cycle analysis in Journal of Industrial Ecology to show that the production of lithium batteries for EVs actually causes more harm to the environment and when “an electric car rolls off the production line, it has already been responsible for 30,000 pounds of carbon-dioxide emission.
” Furthermore, there is an additional disadvantage in the use of EVs - “the stubbornly high cost of the giant battery packs, which can account for half the cost of an electric vehicle” observes Mike Ramsey, an auto-industry journalist in the Wall Street Journal. Advocates of EVs prefer to say that their batteries are charged by electricity from renewable sources of energy, and that many batteries use metals such as nickel, cobalt and manganese and only a small part of lithium (Ramsey 1); the steady prices of the metals used in its making process shall serve only to steady or increase their prices observes Jay Whitacre, a battery researcher and technology policy analyst at Carnegie Mellon University, according to the WSJ article (cited in Ramsey 1).
EVs are still to progress in the aspect of driving range capabilities too, argue the critics. Most EVs have a driving range of 70-80 miles even though some manufacturers claim that their EVs had a driving range of 100 miles. Kris Knapman pointedly reports in the Telegraph Nov 18, 2013 that even though the average driving range of people on a normal day is only 30 miles, people “are still going to get range anxiety when told they can only drive 80-100 miles between eight-hour recharges (reduced to four hours if you use a 32A BMW wallbox).
” Another disadvantage in EVs is the long years taken to get the payback; even Marianne Lavelle of the National Geographic, who sees some advantages in EVs, observes that, “It would take nearly six years for the EV fuel cost savings to pay back the $6,655 initial price premium” for consumers in even states like California that offer more rebates for the purchase of EVs. In other states that do not offer such rebates, the payback may take more time. Furthermore, for EVs the convenience of going to a public re-charging facility is hardly available currently; this is changing and could change further with the number of EVs on roads increasing, placing enormous demands on the amounts of power requirements.
