1. How is geothermal energy being used in single-family homes? Use the link below to answer items A-D below. (10 points) The Guide to Home Geothermal Energy A. What is the principle behind geothermal energy? How can geothermal energy affect indoor temperatures in a home? (3 points) The ground is always around the same temperature so it can keep a house a nice constant temperature. It can pump air that is warmer or colder than the air outside to warm up or cool down a house. B. Describe the components of a geothermal system and how they work together. (3 points) When outside a water-filled, closed loop of 1-inch high-density polyethylene (HDPE) pipe ferries heat between the earth and the house. Pipes descend 4- to 6-inch-diameter vertical wells--the number and depth depend on the house's site and size--before ganging together in a header and bringing lukewarm water in through the basement walls. Drillers backfill each hole with bentonite grout (or new enhanced grouts, engineered with fly ash) to maximize thermal conductivity.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
