Power Generation and Cumulative Capacity of Geothermal Power Plants in United States of America (2017 – 2021)
With the increasing demand for energy, rising levels of pollution, fear of global warming, scarcity of fossil fuels, and increasing levels of greenhouse gas (GHG) emissions, many countries opted for sources of clean renewable energy. Several countries signed protocols with pre-defined emission reduction targets. The Paris Agreement is the most recent initiative in this direction, whereby each country voluntarily determined and presented its emission reduction target and pledged to achieve GHG reduction according to this target. Several countries that are party to the Paris Agreement devised plans to reduce conventional power and aid the growth of renewable power to reduce emissions. The main renewable energy sources are Hydro, Geothermal, Wind, Solar, and Biopower.
Geothermal energy is the thermal energy formed in Earth’s crust due to radioactive decay of material. This energy is extracted using a geothermal heat pump where water or anti-freeze solution is pumped in to absorb the heat and then converted to electricity using turbines. Geothermal energy only produces one-sixth of carbon dioxide in comparison to a natural gas powerplant and is constantly available unlike other renewable sources such as solar and wind.
The US is one of the five major producers of geothermal energy, along with Turkey, the Philippines, New Zealand, and Indonesia. The cumulative installed capacity for geothermal power in the US was 3.735 GW in 2017, which increased to 3.86 GW by 2021, at a CAGR of 1.0%. It is expected to reach 4.59 GW by 2030, growing at a CAGR of 1.73% during 2020–30. Geothermal power generation increased to 17.126 TWh in 2021 and is expected to reach 20.7 TWh by 2030. In the US, the state of California leads the power generation from geothermal technology.
The US government has extended generous support to the renewable energy industry over the past 10 years. It has implemented various renewable energy incentive programs at the federal and state levels providing support for different renewable energy technologies.
