Advantages of Geothermal power
We know that geothermal energy is a green energy and an alternative energy. Geothermal resources range from shallow ground to hot water and rock several kilometres below the Earth's surface, and even further down to the extremely hot molten rock called magma.
Advantages of Geothermal power
Geothermal power requires no fuel, and is therefore virtually emissions free and insusceptible to fluctuations in fuel cost.
And because the geothermal power station doesn't rely on transient sources of energy, unlike, for example, wind turbines or solar panels, its capacity factor can be quite large; almost up to 90% in practice.
Geothermal power (geothermal energy) is considered to be sustainable because the heat extraction is small compared to the size of the heat reservoir.
While individual wells may need to recover, geothermal heat is inexhaustible and is replenished from greater depths. The long-term sustainability of geothermal energy production has been demonstrated at the Lardarello field in Italy since 1913, at the Wairakei field in New Zealand since 1958, and at The Geysers field in California since 1960.
Geothermal has minimal land use requirements. And existing geothermal plants use 1-8 acres per megawatt (MW) versus 5-10 acres per MW for nuclear operations and 19 acres per MW for coal power plants.
Geothermal also offers a degree of scalability: a large geothermal plant can power entire cities while smaller power plants can supply more remote sites such as rural villages.
