We’d all like to reduce or eliminate our reliance on gasoline for a variety of reasons. In spite of great strides in emissions reductions, gasoline engines are still a major factor in air pollution. America’s appetite for oil from distant countries plays a large role in our economic and foreign relations policies. Switching to a form of energy that could be created in the United States could only improve the situation. These are laudable goals, and it’s good to see Americans thinking of long-term goals that will be good for the country as a whole. Many people are even willing to pay a little more than necessary to help achieve these goals, but there is a limit. Alternative forms of energy won’t really gather long-lasting momentum until they become cost effective for the majority of consumers.
We’ve seen the number of hybrids on the road increase, partially due to government incentives and spikes in gasoline prices. But the price of hybrids remains stubbornly higher than the price of comparable gasoline-only cars. For example the new 2010 Honda Civic Hybrid starts at $23,800, while the regular Honda Civic sedan starts at $15,655. The majority of consumers are only going to spend the extra $8,000 if they think they can recoup that cost. Is the better gas mileage going to help you save $8,000 over the life of your car?
The regular Civic gets about 29 mpg, which is pretty good. Compare that to 42 mpg for the Civic Hybrid. Using an average of 15,000 miles per year and a price of $3 per gallon, we see that the owner of a regular Honda Civic would pay about $1,551 in a year, compared to $1071 for the owner of the hybrid. That’s a savings of only $480 a year. It would take more than 16 years to break even. Most people don’t keep their cars nearly that long.
The culprit is the price of the batteries. Like most other car manufacturers, Honda uses a nickel-metal-hydride (NiMH) battery in its hybrids. Price is not the only drawback to these batteries. They tend to lose capacity over time if they are not fully depleted before being recharged. As their capacity decreases, so does your gas mileage.
There’s a newer type of battery called the lithium-ion battery. It’s being used to power all-electric vehicles like the Nissan Leaf and the Chevy Volt. They have a longer range and they hold a charge better than NiMH batteries. Unfortunately they also cost more. A price tag of about $10,000 makes it expensive to go green. The other cost that no one seems to mention in regards to all-electric vehicles is the cost of the electricity itself. Unlike hybrids, where the engine recharges the battery when you drive, batteries on all-electric cars are recharged by plugging in to an electrical outlet in your garage. The power company is going to charge you for the electricity.
Rechargeable car batteries are relatively new. As consumer interest in cleaner cars with low operational costs increases, so will research and development of these batteries. Until they get significantly less expensive, hybrid and electric vehicles will not be economically viable choices.
