From towers to troughs to dishes to linear mirrors, concentrating solar power (CSP) technologies reflect and collect solar heat to produce electricity. A single CSP plant can produce enough electricity for about 90,000 houses. This video describes the way that it operates, what CSP is, and systems like parabolic troughs generate renewable power.
