Marketing Individual Critique Report Word Count: 1‚079 By Desmond Leong The Subject Matter The subject matter of the article revolves around the benefits of purchasing an electric car over conventional fuel powered cars. The article also addresses the various aspects beyond the traditional debate on whether electric cars are simply a greener alternative to fuel powered cars‚ it dwells‚ albeit not too deeply‚ at the political perspective of sustainability‚ the economic advantages and convenience

Electric vehicle problems and solving methods The three main problems for the electric vehicle are about the generation of electricity‚ recharging station‚ and the battery. For the generation of electricity‚ the increase in electric vehicles will also increase the production of electricity from thermal and nuclear power plants‚ impact on the environment will be negative. The main positive impact of electric cars is friendly to the environment. However‚ a lower cost of electricity generation

Disadvantages of Electric CarsAdvantages ~ a safe way to convert fossil fuels into automotive power ~ more efficient than gas-powered vehicles because their fuel can be harnessed from any source of electricity‚ which is available in most homes and businesses ~ the electricity created by electric cars is created by the burning of fossil fuels at power plants‚ instead of in an internal-combustion engine which pollutes the air. ~ the only new system required for electric cars is one that

(Plug-in Hybrid Electric Vehicle) says Ben Hewitt‚ another advocate of hybrid cars. The hybrid vehicle also does not produce any Carbon-Dioxide from a stop‚ and does not produce any Carbon-Dioxide moving at less than under forty miles per hour. These pros‚ nonetheless‚ are better than a pure-gas engine‚ which compares with an average 21 mpg (estimation courtesy of EPA)‚ and produces Carbon-Dioxide all of the time that it is running. But‚ these pros do not scratch the surface of the pure-electric car and

friendly cars I will be discussing to you about are an electric cars‚ hybrids‚ and smart cars. First up are electric cars. An electric car is an automobile that is propelled by one or more electric motors‚ using electrical energy stored in batteries or another energy storage device. The energy crises of the 1970s and 80s brought a short-lived interest in electric cars‚ but in the mid-2000s a renewed interest in the production of electric cars took place‚ due mainly to concerns about rapidly increasing
