Solar thermal plants use sunlight to generate heat, which is then converted into electricity. They typically consist of large mirrors or lenses that focus sunlight onto a receiver, where a fluid is heated. This hot fluid can then produce steam to drive a turbine connected to a generator. These plants can store heat for later use, allowing them to produce electricity even when the sun isn't shining. Solar thermal technology is different from photovoltaic systems, which convert sunlight directly into electricity. Both methods contribute to renewable energy efforts and help reduce reliance on fossil fuels.
