Black's Law Dic- tionary defines “ employee ” as “a person in the service of another under any contract of hire, express or implied, oral or written, where the em- ployer has the power or right to control and di- rect the employee in the material details of how the work is to be performed.” Employment is a relationship between two parties , usually based on a contract where work is paid for, where one party, which may be a corporation , for profit , not-for-profit organization , co-operative or other entity is the employer and the other is the employee .Employees work in return for payment , which may be in the form of an hourly wage, by piecework or an annual salary , depending on the type of work an employee does or which sector she or he is working in. Employees in some fields or sectors may receive gratuities , bonus payment or stock options . In some types of employment, employees may receive benefits in addition to payment. Benefits can include health insurance...

The organization of the electrical sector of a country or region varies depending on the economic system of the country. In some places, all electric power generation, transmission and distribution is provided by a government controlled organization. Other regions have private or investor-owned utility companies, city or municipally owned companies, cooperative companies owned by their own customers, or combinations. Generation, transmission and distribution may be offered by a single company, or different organizations may provide each of these portions of the system India's power sector is one of the most diversified in the world. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste The electric power industry is commonly split up into four processes. These are electricity generation such as a power stati...

Energy Star (trademarked ENERGY STAR ) is an international standard for energy efficient consumer products originated in the United States . It was created in 1992 by the Environmental Protection Agency and the Department of Energy . Since then, Australia , Canada , Japan , New Zealand , Taiwan , and the European Union have adopted the program. Devices carrying the Energy Star service mark, such as computer products and peripherals, kitchen appliances, buildings and other products, generally use 20–30% less energy than required by federal standards. In the United States, the Energy Star label is also shown on EnergyGuide appliance label of qualifying products. Energy Star specifications differ with each item, and are set by either the Environmental Protection Agency or the Department of Energy. The following highlights product and specification information available on the Energy Star website. About Standards & Labeling Program The Objectives of Standards &...

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction . A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described this effect. Transformers are used to increase or decrease the alternating voltages in electric power applications. Since the invention of the first constant-potential transformer in 1885, transformers have become essential for the transmission , distribution , and utilization of alternating current electrical energy. A wide range of transformer designs is encountered in electronic and electric power applications. Transformers range in size from RF transformers less than a cubic centimeter in volume to units interconnectin...

Solar power is the conversion of energy from sunlight into electricity , either directly using photovoltaics (PV), indirectly using concentrated solar power , or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaic cells convert light into an electric current using the photovoltaic effect . Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California . As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar...

Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water , to protect the hydrosphere , and to meet the current and future human demand . Population, household size, and growth and affluence all affect how much water is used. Water conservation refers to the preservation, control and development of water resources, both surface and groundwater, and prevention of pollution Water efficiency is reducing water wastage by measuring the amount of water required for a particular purpose and the amount of water used or delivered. Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use.Solutions for water efficiency focus not only on reducing the amount of potable water used, but also on reducing the use of non-potable water where appropriate (i.e. flushing toilet , watering landscape , etc.). It also emphasises the influence consumers can have in water e...

An electrical grid is an interconnected network for delivering electricity from producers to consumers. It consists of generating stations that produce electrical power, high voltage transmission lines that carry power from distant sources to demand centers, and distribution lines that connect individual customers . Power stations may be located near a fuel source, at a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. They are usually quite large to take advantage of economies of scale . The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network. The bulk power transmission network will move the power long distances, sometimes across international boundaries, until it reaches its wholesale customer (usually the company that owns the local electric power distribution network). On arrival at a substation , the power will be...
