What are steam turbines commonly used in?

Steam turbines are primarily used to convert thermal energy into mechanical energy and are widely used in electric generators. In large-scale applications, steam turbines are integral to power generation facilities where they help convert steam produced from heating water into electricity. This process takes advantage of the efficiency and high power output capabilities of steam turbines.

In addition to electric generators, steam turbines are also utilized in marine propulsion systems where they can drive a ship's propellers, including in naval vessels and certain types of commercial ships. The USNS Mercy, a hospital ship, does incorporate steam turbines, which contributes to its ability to move efficiently and support various operations.

While steam turbines play a role in the propulsion of some maritime vessels, their primary and most common application remains within electric power generation, making that the most significant context in which they are utilized.
