Geothermal systems harness the natural heat from the Earth to provide energy for heating and cooling buildings. This heat comes from the Earth's core and can be accessed through wells or geothermal heat pumps. By transferring heat from the ground into a building during winter and vice versa in summer, these systems offer an efficient and sustainable way to regulate indoor temperatures. These systems are environmentally friendly, as they reduce reliance on fossil fuels and lower greenhouse gas emissions. Many homes and businesses are now adopting geothermal technology, making it a popular choice for those looking to invest in renewable energy solutions like geothermal heat pumps and ground-source heat exchangers.
