Question

Solarthermal electric energy generation concentrates the light from the sun:

A) To create electricity directly
B) For cooking purposes
C) To produce thermal energy
D) To charge batteries

Answer 1

Solar thermal electric energy generation concentrates sunlight to produce thermal energy, which is then used to generate steam that powers a turbine to create electricity.

Step-by-step explanation:

Solar thermal electric energy generation concentrates the light from the sun to produce thermal energy that is then used to generate electricity. This process involves using devices such as a parabolic trough or concentrating collector to focus sunlight onto a pipe containing a fluid. The fluid is heated and pumped to a heat exchanger where it transfers its heat to generate steam. The steam then powers a turbine, which in turn generates electricity through a conventional steam cycle. This indirect method of converting solar energy into electrical energy is distinct from photovoltaic cells, which convert sunlight directly into electricity.
