Who is Behind the Electricity Generator?

In electricity generation, a generator is a device that converts motive energy into electrical energy for use in an external circuit. Mechanical power sources such as steam turbines, gas turbines, hydraulic turbines, internal combustion engines, and wind are used to generate electricity. Crude oil, gasoline, heating fuel, diesel, propane and other liquids, including biofuels and natural gas liquids are also used. Exploration and reserves, storage, imports and exports, production, prices, sales are all part of the process.

Sales, revenues and prices, power plants, fuel use, stocks, generation, trade, demand & emissions are all monitored. Energy Use in Homes, Commercial Buildings, Manufacturing and Transportation is tracked. Reserves, production, prices, employment and productivity, distribution, stocks, imports and exports are all monitored. This includes hydroelectric, solar, wind, geothermal, biomass and ethanol energy.

Uranium fuel, nuclear reactors, generation, spent fuel are all tracked. Monthly and annual energy forecasts are made along with analysis of energy issues and financial analysis. Congressional reports are also made. Financial market analysis and financial data for major energy companies is also tracked.

Greenhouse Gas Data is monitored along with Voluntary Reporting and Power Plant Emissions. Maps, tools and resources related to power outages and infrastructure are available. State energy information is available including summaries, ratings, data and analysis. Maps by energy source and topic are available including forecast maps.

An electrical generator is a device that converts a form of energy into electricity. There are many different types of electricity generators. Most of the world's electricity generation comes from generators that are based on scientist Michael Faraday's discovery in 1831 that moving a magnet inside a wire coil causes (induces) an electric current to flow in the cable. He made the first electricity generator called the Faraday disc which works on this relationship between magnetism and electricity which led to the design of the electromagnetic generators we use today. Electromagnetic generators use an electromagnet a magnet produced by electricity not a traditional magnet.

A basic electromagnetic generator has a series of insulated wire coils that form a stationary cylinder called a stator that surrounds an electromagnetic shaft called a rotor. Rotating the rotor causes an electrical current to flow in each section of the wire coil which becomes a separate electrical conductor. The currents in the individual sections combine to form a large current. This current is the electricity that passes from generators through power lines to consumers. Electromagnetic generators driven by kinetic (mechanical) main motors represent almost all U S Flue gas turbines which are similar to jet engines burn gaseous or liquid fuels to produce hot gases that rotate the turbine blades Combined heat and power (CHP) plants which may be referred to as cogenerators use heat that is not directly converted to electricity in a steam turbine combustion turbine or internal combustion engine generator for industrial process heat or for space and water heating. Most of the largest cogeneration plants in the United States are located in industrial facilities such as pulp and paper mills but they are also used in many colleges universities and government facilities Cogeneration and combined cycle power plants are among the most efficient ways to convert fuel into useful energy Ocean Thermal Energy Conversion (OTEC) systems use a temperature difference between ocean water at different depths to power a turbine and produce electricity. There are many different types of power generators that don't use turbines to generate electricity The most widely used today are solar photovoltaic (PV) systems and internal combustion engines Internal combustion engines such as diesel engines are used worldwide for electricity generation including in many remote villages in Alaska They are also widely used for the supply of mobile power on construction sites and for the supply of emergency or backup power for buildings and power plants Diesel engine generators can use a variety of fuels including oil diesel liquid fuels based on biomass and biogas natural gas and propane Small internal combustion engine generators powered by gasoline natural gas or propane are commonly used by construction crews merchants and for emergency power supply for homes. Other types of power generators include fuel cells Stirling engines (used in solar thermal parabolic plate generators) thermoelectric generators Energy storage systems for power generation include hydropumped storage compressed air storage electrochemical batteries flywheels These energy storage systems use electricity to charge a storage facility or device and the amount of electricity they can supply is less than the amount they use to charge Therefore the net electricity generation of the storage systems is counted as negative to avoid double counting the use of electricity to charge the storage system. News & Technology for the Global Energy Industry The history of power generation is long and complicated marked by countless technological conceptual technical milestones of hundreds of collaborators Many stories begin the history of energy in the demonstration of electrical conduction by Englishman Stephen Gray which led to the 1740 invention of glass friction generators in Leyden Germany This development is said to have inspired Benjamin Franklin's famous experiments as well as the invention of the battery by Italian Alessandro Volta in 1800 Humphry Davy's first effective “arc lamp” in 1808 Hans Christian Oersted's demonstration of the relationship between electricity magnetism Michael Faraday Joseph Henry's primitive electric motor 1831 documented electric current can be produced cable moves close magnet demonstrating principle generator 1877 streets many cities around world...
