The parabolic trough approach of harvesting solar energy is an example of thermal solar power.

Explanation:

A parabolic trough reflector is a type of solar power collector that can generate higher temperatures with good efficiency. The surface of reflector is a U-shaped parabola that focuses all the sun's radiation on the receiver placed at the focal point axis of that reflective parabola. In this way, the solar energy received is increased by more than a factor of 2. This technology is used to either generate heat or electricity thus is an example of solar thermal energy.
