Concentrated Solar Power

Definition

Concentrated solar power (CSP) is a renewable energy technology that uses mirrors or lenses to focus sunlight onto a small area, generating heat that is then converted into electricity. This technology harnesses solar energy on a larger scale, allowing for efficient energy production and storage, making it a vital component of sustainable energy strategies aimed at increasing energy access and reducing carbon emissions.
