Today, scientists estimate that given what we now know about the amount of geothermal energy in the earths crust, about 1% of that energy amounts to 500 times what exists in all the oil and gas resources on the planet. In the summer, the process is reversed, and the heat pump uses power again to move heat from the indoor air into the heat exchanger. Geothermal energy escapes as hot water at many hot springs or as steam at geysers. In the winter, the heat pump uses power to remove heat from the heat exchanger and pumps it into the indoor air delivery system. The temperature just 30 feet below the surface of the Earth remains about 50 to 60 degrees Fahrenheit all year round.

There are different types of geothermal energy systems: hot springs, geothermal heat pumps, and geothermal power plants. They heated their dwellings, cooked their food, and even got a warm bath without a water heater. Geothermal heat pumps take advantage of this constant temperature to heat or cool water. Geothermal energy uses 3 basic types of geothermal power plants like: Dry Steam, Flash Steam and Binary power plant. The geothermal bathing and thermal beauty products represent another use of geothermal energy. This is done in different ways: the oldest is the dry steam method that uses steam found in deep cracks in the rocks to drive turbines; the flash method moves extremely high pressure water into low pressure water that is cooler, and this creates steam that drives the turbines; the binary method passes very hot water through another liquid that has a lower boiling point than water, causing that liquid to become steam that drives the turbines. Water or a refrigerant moves through a loop of pipes. Geothermal energy is a renewable source of energy (which means it can be continuously used and naturally replenished) because the center of the Earth never cools down. Holes are drilled down to hot rocks sometimes thousands of metres below the surface. The centre of the Earth is extremely hot around 6000oC. It is a clean and affordable source of alternative energy. Geothermal heat pumps - About 10 feet below the surface of the Earth, the ground is a consistent temperature between 50 and 60 F throughout the year. This is also where you find the most volcanoes and get the most earthquakes. Access to these resources involves injecting cold water down one well, circulating it through hot fractured rocks, and drawing off the heated water from another well. Hot water near the surface of Earth can be used directly for heat. The hot lava from a volcano and the hot steam from a geyser both come from underground heat and we can use that same type of heat in our homes. | A Guide to Summative Assessment, Active Learning | Definition & Strategies for Teachers, Prentice Hall World History Connections to Today Volume 1: Online Textbook Help, High School Chemistry: Homeschool Curriculum, Physical Science for Teachers: Professional Development, Business Calculus Syllabus & Lesson Plans, Shakespeare for 10th Grade: Tutoring Solution, The Progressive Era (1900-1917): Homework Help, Quiz & Worksheet - Average Collection Period, Quiz & Worksheet - Atlas in Greek Mythology, Quiz & Worksheet - Video Editing Software, Quiz & Worksheet - Entropy in Machine Learning, Quiz & Worksheet - Substitution Property of Equality, How to Do 1-Sample t-Tests: Steps & Tutorial, Excelsior College BS in Business Degree Plan Using Study.com, PMI-SP Eligibility Requirements: Education & Experience, Tech and Engineering - Questions & Answers, Health and Medicine - Questions & Answers, Which of the following statements best describes why geothermal heat pumps work: a) they are located in areas with abundant geothermal energy.
