Review Hybrid Cars

Depends on how much energy it takes to make a new hybrid car compared to the energy your sports car is already consuming… Everything takes energy - the company has to build a new car before you can drive it…

It's not. The argument is based on the principle that it takes a certain amount of raw materials and energy to construct a new car.

However, this argument neglects the fact that studies have shown that 80-90% of a car's lifetime energy use comes during the operational stage (while driving), and just 5-10% during construction. Thus the better your fuel efficiency, the lower your total carbon footprint is. See pages 4-5 here:

Although 2010 is being touted as 'the year to buy a new car' because some even more efficient technologies will be coming out around then, so it might be worth waiting a couple years (see link below).

The negative effects of the hybrid cars are not brought to the attention of the buyer primarily because the negative effects take place in the production process.

Since Hybrid vehicles have a far more complex system than standard fuel powered cars, there is more production and energy costs that come at stake during production. While hybrids are considered clean technology by most people, any hybrid with an internal combustion engine will still produce pollutants. Special converters are installed in hybrid cars that help clean contamination; however, the lovely greenhouse gases (CO2) are still produced by any car on the market. Hybrids pump out CO2 just like fuel economy cars, it just produces it in lower amounts

Another thing to consider with hybrids is the battery that stores the electricity. Most hybrids use a nickel metal hydride system, which requires nickel mining, which is often done in open cast mines with all the attendant pollution that goes along with excavating large holes in the ground. Luckily, nickel metal hydride batteries are non toxic and they can be recycled, but at a cost.

The internal structure of the hybrid car requires an extensive amount of copper wiring. This in turn increases the effect on production and the environment.

Once the car is built and on the road, the popular perception is that you are ‘doing your thing for the environment’ and this is true to some extent because a hybrid will use less fossil fuel than a conventional car, regardless of the way you drive it. Remember that a hybrid will probably never match the listed fuel efficiency because of the way the efficiency test is done, and because unless you only ever drive on heavily congested streets you won’t be utilizing the hybrid system effectively. Drive on the highway, for instance, and the petrol engine will be working all the time, negating the effect of the hybrid system.

If you live in Utah or Oklahoma, forget the hybrids, which still use foreign oil, and buy yourself a car that runs on natural gas (methane). It's dirt cheap in these two states, is much, much cleaner burning than gasoline, and we have lots of it here in the U.S.A. In Utah, natural gas is 64 CENTS per gallon, and it isn't much more than that in Oklahoma. Do an end run around the oil companies and go with natural gas!
