Electrical Power in the United States

We for the past decades United States has been the largest importer of energy resources throughout the world. We consume almost 7 billion barrels of fuel in various forms such as crude oil, petroleum, gasoline, biodiesel etc. And how much do we produce on own?

Introduction: Voltage can be thought of as the pressure pushing charges along a conductor, while the electrical resistance of a conductor is a measure of how difficult it is to push the charges along. Using the flow analogy, electrical resistance is similar to friction. For water flowing through a pipe, a long narrow pipe provides more resistance to the flow than does a short fat pipe. The same applies for flowing currents: long thin wires provide more resistance than do short thick wires. The resistance (R) of a material depends on its length, cross-sectional area, and the resistivity (the Greek letter rho), a number that depends on the material. The resistivity

Power production can come from multitude of sources with different types of power plant facilities each with some sort of unique need; these sources include coal, natural gas, nuclear, wind, water also known as hydroelectric, solar, geothermal and biomass (U.S. Energy Information Administration). These energy sources are broken down into one of two categories, renewable or nonrenewable.

Electricity can be generated from any source of energy which is available in abundance and can be used effectively.

Electric current is the flow of charge through an electrical component. The speed of an electric current can be measured in the SI units of ‘amperes’ (abbreviated ‘amps’). The formula for the voltage of an object is ‘voltage ÷ resistance’.

Electricity is a form of energy involving the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons (Joseph, 2002)The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons (Joseph, 2002).When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current (Joseph, 2002). To understand electricity one must know that it is not an invention but a

Electric cars enjoyed a stint of success before their early demise at the end of the 19th century, beginning of the 20th century. There is insufficient evidence on the activity of electric cars outside of the United States, so this section will center on what took place in the U.S. Electric Cars industry. In the U.S., electric vehicles were pervasive throughout the east coast, along with internal combustion and steam engines. Around 1900, 28% of cars in the United States were electric vehicles. It was marketed as a niche product and the primary target of such vehicles were females and professionals, specifically of upper class. Unlike the ICE, electric vehicles did not require a hand crank to power it. Early electric vehicles were massive, decorative carriages with luxurious interiors and expensive materials. These extra additives increased the cost of the vehicle from $1,000 ($28,000 today) to $3,000 ($84,000 today). There are two theories regarding the fall of electric vehicles, lack of innovation compared to the internal combustion engine and the bankruptcy of the Electric Vehicle Company.

The existing green energy sources are solar energy, wind energy (harvested using wind turbines), geothermal energy (harvesting energy trapped in the earth), biogas (natural gas beneath the earth surface) and biomass (energy from biological material) apart from the hitherto mentioned hydroelectric source (EPA, 2012).

There is another important property that can be measured in electrical systems. This is resistance, which is measured in units called ohms. Resistance is a term that describes the forces that oppose the flow of electron current in a conductor. All materials naturally contain

Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons.

Our world is powered by electricity; it surrounds us in every turn and every corner, powering our streetlights, our TVs, our hospitals, our homes, and our communities. Electricity is a form of energy that results from charged particles. There are many energy sources that can be converted into electricity, and that’s why it is suited for powering our society. We can generate electricity from burning fuels, energy of falling water, solar energy, and basically anything that has energy. Electricity is also easy to distribute, using transmission lines connecting the energy power station to homes, schools and so on. Atoms consist of electric charge, so electric charge is everywhere and the electric charge has an electric field. An electric field can only be created by a positive charge and destroyed by a negative charge(Brightstorm, 2010). According to Bob emery, owner of senior physics website, to generate electric power it requires motion between a magnetic field and a conductor. Attraction of a magnet is limited to certain boundaries this is called the magnetic field of a magnet (Makemegenius, 2013).

Although it may seem like a simple topic it is in fact the opposite. The history of electricity goes way back and has many contributors that helped to generate the technology we have today, that we

The generation of electricity is the process of producing electric energy or the amount of electricity produced by transforming/converting other forms of energy into electrical energy. There are many ways to produce electricity. For instance, in a common battery, electrons can flow between certain materials enduing a current which is required to provide power for the object in which the battery is situated. Although the chemical batteries are portable and reliable, they eventually run out. However the large amounts of power demanded by modern society requires large power plants, which have since been built to meet this demand. Most power plants use generator to produce electricity. Electricity cannot be mined or harvested, it has to be manufactured. And since it is not able to be stored in large quantities, it must be manufactured at time of demand. Electricity is a form of energy but not an energy source. There are different types of power plants and therefore these different generating plants obtain distinct energy sources to produce electrical power. The two main types are “Thermal plants” and “Kinetic plants”. Kinetic generating plants consist of hydro-electric plants and wind mills, converting energy into electricity. Instead of heat energy, they use kinetic energy, or the energy of motion. Moving wind or water spins a turbine, which in turn spins the rotor of a generator. Thus electricity is produced. Thermal plants use the energy of heat to produce electricity. Water

In the modern world we use energy for anything such as to power our house, to drive our car, cellphones and many other
