Concentrated Solar Power (CSP) is a technology that uses mirrors or lenses to focus sunlight onto a small area to generate heat and produce electricity. Think of it as using many mirrors to direct sunlight into one spot, like using a magnifying glass but on a much larger scale. Unlike regular solar panels that convert sunlight directly into electricity, CSP first turns sunlight into heat, which then powers traditional steam turbines to make electricity. This is particularly useful for large-scale power plants in sunny regions. Other names for this technology include "solar thermal power" or "concentrating solar thermal."
