This is the energy that is received from the Sun. Answer: A geothermal energy resource has been termed in many ways: earth power, earth heat, geothermal reserve, geothermal reservoir, geothermal field, ... Lindal diagram (Lindal, 1973), it is logical and common to categorise resources that can be used for the generation of electricity using conventional steam You can edit this Block Diagram using Creately diagramming tool and include in your report/presentation/website. The geothermal gradient is the driving force for the continuous conduction of thermal energy in the form of heat from the core to the surface. Geothermal energy is a type of renewable energy source derived from the heat deep in the earth’s crust. Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy).They essentially work the same as a coal or nuclear power plant, the main difference being the heat source.With geothermal, the Earth's heat replaces the boiler of a coal plant or the reactor of a nuclear plant. When u… Learn more about geothermal energy and other non-conventional methods for the production of energy with the team of expert mentors at BYJU’S. It is the most commonly adopted alternative energy sources in the present time. Geothermal heat pumps can do all sorts of things—from heating and cooling homes to warming swimming pools. The power output of a geothermal power plant is highly predictable and stable, thus facilitating energy planning with remarkable accuracy. This steam is used to run turbines and produce electricity. Geothermal power plants are also an excellent means of meeting baseload energy demand, or the minimum level of demand on an electrical grid during a 24-hour period. 7.5. The center of the Earth remains at the same temperature as the Sun which is nearly constant due to the continuous process of nuclear fusion. The basic elements of a geothermal heat pump system include: Ground loop — system of fluid-filled plastic pipes buried in the shallow ground, or placed in a body of water, near the building. A few years later, in 1911, the first geothermal electric plant was built. Our tips from experts and exam survivors will help you through. Learn about the uses of geothermal energy and their history and … It literally means earth-heat as Geo means earth and thermos means heat in Greek. In this process, a hole is drilled deep under the earth, through which a pipe is inserted. Not all geothermal energy comes from power plants. The diagram shows how this works. Your email address will not be published. The diagram highlights the process by which geothermal energy is harnessed to generate electricity. Industry: Geothermal energy is used in industries for the purpose of food dehydration, milk pasteurizing, gold mining, etc. It is a clean, renewable resource that provides energy in the U.S. and around the world in a variety of applications and resources. However, where the upfront costs are high, the outlay can be recouped as part of a long-term investment. Alternative Energy SourcesGeothermal energyApplicationsAdvantagesDisadvantages. Read about our approach to external linking. Sign in, choose your GCSE subjects and see content that's tailored for you. The diagram shows how this works. Diagram of a geothermal power plant Through the fractures in the layers of rock, water and steam which has been heated in the depths, rise to the surface and are intercepted in the geothermal wells. Intensive research required: Before setting up a plant, extensive research is required, as the sites can run out of steam over a period of time due to a drop in the temperature as a result of excessive or irregular supply of inlet water. Transportation and transmission: Unlike fossil fuels, geothermal energy cannot be transported easily. Answer: The flowchart illustrates the production of electricity by using from geothermal energy. Sustainability. When this hot water gushes out of one of these outlets, it is called hot springs. The steam from these reserves is either directly used to rotate the turbines of an electrical generator or is used to heat water which then produces steam for the process. 1.1. The wind power is controlled to push the blades of the wind turbine that are connected to the electric generator to produce wind energy. Geothermal energy, form of energy conversion in which heat energy from within Earth is captured and harnessed for electrical power generation, space heating and cooling, and various direct uses.
