There is currently a challenge that the world is facing; the need for a convenient and affordable form of transportation that does not contribute to the destruction of the environment. There are many obstacles that make this a difficult task to achieve. Hybrid cars do use electricity as one of their main sources of energy, however the batteries used in these cars do not store enough charge to ensure the car’s ability to travel great distances. Because of this, hybrid vehicles have a second engine which runs on gasoline. The electric motors powering these vehicles enables the car to travel more miles per gallon consumed, effectively reducing the drivers carbon footprint. It is hard however, to imagine that less greenhouse gases are being produced when thick black smoke can be seen coming out of trucks, buses and cars, seemingly marking its territory in urban cities.
Although it has already been hundreds of years since electricity has made its way into technology, new methods to utilize and store electrical charge are still being developed. Thermal and kinetic energy are converted into a usable form of energy, electricity, by placing solar panels in areas where the sun shines much of the day or wind turbines in places with constant gusts of wind. This electrical energy then makes its way to schools, businesses and homes via power lines that can safely carry the electricity for large distances. Unlike petroleum which is usually obtained via some form of digging, whether it be on land or off-shore, electricity can be obtained without any invasive procedures that damage the environment.
While modern electric and hybrid vehicles regain some of the energy expended through normal uses such as braking, electric vehic...

... application for ultracapacitors is that for modern cars made for the public. Engineers have discovered a way to store energy that would have otherwise been lost from braking in a vehicle. Hybrid electric vehicles use only this mechanism to restore its energy. Because of this, hybrid cars still rely pretty heavily on gas and in fact cannot run without gas in the tank.

- What is electricity. The term electricity means the force that makes electronics move from place to another. This is similar to the meaning of the engine as the force that moves a car or any mechanical machine. However, here it is explained as the effect not the physical movement. Throughout the ages, scientists have realized that electricity’s behavior can be predictable pattern when subjected to given conditions (Naiah & Kamakshaiah, 1995). What Electrical engineering. Electrical engineering is a field that deals with the applications the technology of electricity, such as generating, distributing electrical energy, and programing electrical systems....

- Four decades ago gas was on the double digits. Well now you don't have to worry about buying gas , With an electrical vehicle. The first electric car was operated in the 80s. Electrical car were popular in the late 19th century and the early 20th century, until advances in the internal combustion engine technology mass production was cheaper, Than gasoline vehicles led to the decline in the use of electric drive vehicles, The energy crisis of the 1970s and 1980s a short-lived interested in electric cars, although these cars did not reach the mass marketing stage, as in the case of 21 century....

- Electrical Engineers Engineering is a very important occupation in our society. Many things (phones, computers, buildings, desks, chairs, toys etc.) that we have today had to be designed and innovated, and that's what engineers do, design and innovate. Electrical Engineers design electronic equipment, devices, or objects, like; “computers, robots, cell phones, cards, radars, navigation systems, wiring and lighting in buildings, and much, much more. They do many different things and design a lot of things.... [tags: Electrical engineering, Engineering]

- Purpose: The primary purpose of this experiment was to find out what environmental factors if at all affect the rate of transpiration. Transpiration is the process in plants which water taken from the roots are evaporated at the leaves. For the water to be transported through the plant, surface tension, adhesion and cohesion are important as it holds the water together and attached to other surfaces. If transpiration is affected by environmental factors, then increasing the wind and light/temperature will have a direct correlation of transpiration rate; furthermore, wind and light/heat combined will affect the rate larger than just one factor by itself....

- Electrical engineering is a building science that applies power in an innovative and down to earth way. Outside of the United States, electrical engineering is thought to be centered on extensive scale frameworks, for example, force and hardware building to be centered on little scale frameworks, for example, PCs. An option refinement alludes to electrical engineering as the study and utilization of power to transmit vitality and hardware building as the study and use of power to process frameworks....
