Geothermal energy delivers base load electricity. This means electricity can be generated continuously, 24 hours a day, 365 days a year. Electricity supplies generated by geothermal energy are not dependent on sunshine, wind or waves, which are variable and interruptible sources, and also subject to climate change and seasonal fluctuations.

Base load electricity generated from geothermal energy is clean, renewable and has minimal impact on the environment. The closed loop circulation of fluids is environmentally benign. Unlike burning fossil fuels, the process emits no greenhouse gases, pollution or hazardous wastes. Geothermal power plants have small footprints compared to coal, nuclear power plants and windfarms. Geothermal injection and production wells are lined with metal casing and cement so that the circulating fluids are isolated from groundwater and the environment. Customers can access safe, environmentally friendly, renewable, and long life domestic base load energy resources. It also reduces the need for imported fuels.
