The largest geothermal power plants of the world

by DrPrem Jagyasi

Geothermal energy is fast being considered as a potential alternative to fuel based energy. In addition to being renewable, geothermal energy has minimum impact on the environment. Hence, it is also considered as one of the cleanest energy sources one can opt for on earth. Geothermal energy is currently being harnessed by over 50 countries around the world, with that have invested millions of dollars in setting up large scale geothermal plants for the generation of heat and electricity. Accordingly, here is a small insight into some of the largest geothermal power plants in the whole world.

Ngatamariki Geothermal Power Plant, New Zealand

One of the world’s largest binary geothermal plants, the Ngatamariki Geothermal Power Plant is located near North Island in New Zealand. The plant utilizes geothermal fluid to minimize the impact on the environment. Together with the other four geothermal plants already set up in the country, the Ngatamariki Geothermal Power Plant accounts for nearly 10% of the country’s annual electricity related costs. In doing so, the plants successfully keep away nearly 3 million tons of carbon emissions from entering the atmosphere every year.
