S-Curve Insight into the Electric Automobile Industry Introduction Many technological improvements have been made to vehicles to reduce their environmental impact. Some of these advances have been imposed by environmental legislation‚ others have been incentivized by commercial pressure to improve energy efficiency and limit our dependence on fossil fuel. Greening the transportation sector is thus important for meeting global emissions reduction targets. One innovative technology to achieve a green

Currently electric vehicles are slowing becoming popular with some already on show room floors. Furthermore‚ there are many enthusiasts and groups that have really been pushing their use. Tough these cars do not share the same performance qualities of some gas-powered cars; the current technology has been rapidly catching up. Hybrid vehicles have offered in some ways the best of both worlds. The cars are environmentally friendly yet offer the power and distance capabilities of other cars on the market

The Electric Field inside a Conductor The nuclei of the atoms of a conducting solid remain almost in their places in the crystal lattice‚ while the electrons relatively move a lot. In an insulator‚ the electrons are constrained to stay with their atoms (or molecules)‚ and at most‚ the charge distribution is displaced slightly. The motion of the electrons due to the external electric field constitutes an electric current. Since the negatively charged electrons are moving to the left‚ the current

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
