Geothermal power is generated from heat within the Earth and can be used to heat buildings. There are currently nine geothermal power stations operating in New Zealand, located in areas with geothermal activity like Northland, Bay of Plenty, and Waikato. Geothermal power works by pumping steam or hot water from underground up through pipes to power turbines and generate electricity. Schools in New Zealand could use geothermal power since it is readily available from existing power stations and would provide a cheap heating option.
