Image 1           Greetings ladies and gentlemen. Today we will take a look a hybrid

          cars, specifically the hybrid-electric vehicles that have been championed by

          some as to be the next big thing to keep our environment clean. While some

          have praised the potential of Hybrid cars, others have doubted just how

          effective they will be at protecting our environment. Today we will look at

Image 2   how hybrid cars fare for young and middle aged adults. Are they the types of

          cars that can fill the desires of that demographic? Will they do what they claim

          to do for the environment. Please pay attention and listen closely as I present to

          you: “THE HYBRID!

Image 3          Hybrids have been known for reducing gasoline and diesel

          consumption, and recent studies continue to prove it. An article in the Energy

          and Conversion Management Journal reported that across the board Hybrids

          are much more efficient in the consumption of energy and the reduction of

          emissions. The authors note that a large part of the energy consumption

          prowess of Hybrid vehicles comes from their ability to draw power from the

          electrical grid (Silva, Ross, and Farias 1635). Their study also shows that
Image 4   Hybrids strike a strong blow in reducing global carbon dioxide emissions. In

          addition, according to an article in the Electrical Engineering in Japan Journal,
          the various Hybrid types: the bio fuel/fuel cell vehicle (FCV), electric vehicle

          (EV) and plug-in electric vehicle (PHEV), are expected to reduce CO2

          emissions and oil dependence (Yukio, Tanaka, Akisawa, and Kashiwagi 12).

Image 5          In recent years, we have seen record oil and gasoline prices, putting a

          lot of pressure on the working families. It is suggested that the use of hybrid

          electric vehicles can help relieve some of that pressure. A U.S. House

          Subcommittee on Energy and Resources reports that about 70% of the oil used

          in the U.S. is used in the transportation sector, and increasing the use of hybrid

          vehicles to improve the fuel efficiency of America’s cars is necessary in order

          to increase national security. The subcommittee defines a hybrid car as “a

          vehicle that combines an electric motor and a battery pack with an internal

          combustion engine to increase fuel efficiency over traditional automobiles.”

Image 6   According to them, hybrid vehicles are currently 30% more fuel efficient than

          non-hybrid cars, and that number is steadily increases as technology advances.

          That same sub-committee has identified some of the benefits of using Hybrid

          cars include fuel efficiency and potential cost savings, reduced dependence on

          imported oil, emissions reductions, use of existing infrastructure, as well as

          other benefits.

Image 7          While Hybrids have many benefits and their use looks very promising

          for the future, the costs cannot be ignored. According to Jerry Flint, writer for

          Forbes, magazine, some of the problems Hybrid cars is high upfront cost, long

          time period to pay back its initial high cost, and small relative effect on the

          environment compared to other environmental influences. Flint also notes that
           the market for Hybrid cars is currently not very good, with only a small

           amount of people owning Hybrid cars in relations to people owning non-

           Hybrid cars (Flint 42). An article in the Energy and Conversion Management

Image 8    Journal has also identified some of the main costs of Hybrid vehicles to the

           users as “acquisition cost, circulation tax, maintenance cost, and fuel tax”

           (Silva, Ross, and Farias 1641). Some other issues with Hybrid vehicles have

           been discussed at the EVS24 International Battery Hybrid and Fuel Cell

           Electric Vehicle Symposium in Norway. They listed some of the issues as

           availability of required battery technology, high batter costs, questions of the

           capabilities of the electrical infrastructure, and questions of availability of off-

           peak energy and power.

Image 9            Along with high cost, a popular perceived issue with hybrid vehicles is

           the low performance in relation to non-hybrid vehicles. This is especially true

           for young and middle aged adults looking for powerful automobiles. Recently,

           the trend has been to use energy storage systems in hybrid vehicles, resulting

           in lower costs and increased performance, important factors to young and

           middle aged adults (Markel, Pesaran, Zolot, Sprik, Tataria, Duong). The
Image 10
           energy storage systems serve to increase performance by supplementing the

           FC’s limited transient response. As research continues experts expect more and

           more hybrid vehicles to use energy storage systems to help keep costs down

           and performance high, something young and middle aged adults can be happy


Image 11           While the use Hybrids has several costs attached to them for the
           consumer, the benefits to the consumer as well as to society far outweigh the

           costs, and as long as consumers can perceive the overall benefits for consumers

           as a whole as well as the planet, the costs will not be an issue. In addition,

           many of the costs, issues, and questions only need to be discussed, worked out,
Image 12
           and answered. For example, questions of high costs can be answered with

           evidence of future cost savings being worth more than initial high costs. Also,

           questions of infrastructure can be answered by reports that planned

           infrastructure improvements shall be efficient to handle widespread hybrid

           vehicle use (Kalhammer, Kamath, Duvall, Alexander, and Jungers). It is clear

           that Hybrids have a high costs, but the higher benefits outweigh the costs and

           makes it worth it.

Image 13          Recent studies and research has shown that Hybrids are indeed much

           better for the environment than non-hybrid vehicles. They have indeed done

           what they claim to do, and as technology and infrastructure increases, the

           effect shall also increase. While the cost of hybrids vehicles may be higher

           than non-hybrid vehicles, their benefits both to the consumers and to the entire

           world as a whole are too high to pass up. Even for young and middle aged

           adults, hybrids prove to be a good buy as they offer the low price they need as

           well as the high performance that they are looking for.
