Geothermal power plants produce electricity by using steam from hot underground water to turn turbines and activate a generator. Some types of geothermal power plants use the steam to directly turn the turbine, while others use the steam to heat a fluid used to turn a turbine.Know More
The three types of geothermal power plants are binary cycle power plants, dry steam power plants and flash steam power plants.
Flash steam power plants are the most common type of geothermal power plant in the United States. Flash steam power plants use water wells, tapping into underground bodies of boiling water. As the hot water ascends up the well, it produces steam, which is redirected from the water and used to rotate turbines. Excess water and steam are returned to the reservoir in order to ensure sustainability.
Dry steam power plants extract steam directly from extremely hot underground water sources, and they use the energy to turn turbines and generate electricity. In the United States, this form of geothermal power production is only used in a volcanically active area of California.
Binary cycle power plants use slightly cooler water to heat an alternative fluid that has a lower boiling point. This "working fluid" evaporates, and it is used to turn turbines and generate electricity.Learn more about Electricity
Windmills produce electricity by electromagnetic induction, the process in which the movement of magnets in a magnetic field generates electricity. In a windmill, when wind moves the blades of the windmill that move the rotor, the rotor rotates a shaft that holds magnets in the magnetic field of the generator, generating alternating current that is sent along power lines.Full Answer >
Friction produces static electricity by initiating the transfer of electrons between two or more objects. With regards to electron transfers, objects are either conductors or insulators. Conductors give up electrons readily because the electrons are not confined to a particular atom. Insulators do not transfer electrons readily.Full Answer >
Geothermal power is a form of renewable energy generated from heat that naturally occurs within the Earth. Radioactive materials, such as uranium and potassium, decay and produce heat deep underground, which is reachable through weak spots or boundaries in tectonic plates.Full Answer >
The abbreviation "mA" denotes the International System unit for electrical current known as the milliampere. One milliampere is equal to one-thousandth of an ampere. The unit is named for the 18th and 19th century French physicist Andre-Marie Ampere, who studied electromagnetism.Full Answer >
