The main idea here is what a turbine does in wind energy systems. A turbine is a machine that harnesses the kinetic energy of moving air and converts it into mechanical energy to drive a generator, producing electric power. Among the options, this describes the turbine’s role most accurately: harvesting wind energy to generate electricity. The other choices point to different devices entirely—storing electrical energy (like batteries), measuring wind flow (sensors), or converting chemical energy into electricity (fuel cells or similar). So the turbine’s purpose is to transform wind energy into usable electrical power, acknowledging that actual output can vary with wind conditions.
