Image for topic: The diagram shows how geothermal energy is used to produce electricity. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Our system will evaluate the answer based on this AI-generated description.

The image illustrates a geothermal power plant's process of converting geothermal energy into electricity: cold water is pumped 4.5 km down into a geothermal zone containing hot rocks, which heat the water, and the hot water is then pumped up as steam to drive turbines connected to generators producing electricity; post-turbine steam passes through a condenser, cooling to water again, and cycles back.

Given the complexity of the image, the above description may not be entirely accurate.

The diagram illustrates the process of generating electricity using geothermal energy in a power plant.

Overall, producing electric power comprises five key stages, starting with the injection of cold water into the earth and ending with energy conversion by steam.

First, cold water is reserved in a special tank before it is injected into the injection well which is 4,5 km deep. Below the earth’s surface, the water flows through geothermal zone where hot rocks boils it, after which it is pumped up through the production well to condenser above the ground.

Once, in condenser, the pumped water is evaporated into steam which is directed to generator turbine. Subsequently, the steam plays a crucial role in generating power. The turbines are rotated by the steam force, converting mechanical energy into electric energy before introducing to national grid.
