A new solar thermal power station in southern Spain generates enough energy for about 6,000 homes. The 40-stories high concrete tower is bathed with intense light due to the 600 huge mirrors reflecting sunlight from the ground.
The tower is Europe’s first commercially operating power station using the Sun’s energy without emitting any greenhouse gases. Enough energy is made by the tower by focusing the reflected rays onto one location, turning water into steam and then blasting it into turbines to generate power. When the sun goes down, the heat is stored in the form of steam, but for only 1 hour. There is hope to make it longer in the future. Although, highest demand for energy is during the day especially during the summer months when residents crank up the air conditioning.
So far, only one field of mirrors are functionally while a second much larger field is being cleared out to place thousands more mirrors. Ultimately the plan is not only to have this plant generate enough electricity for 6,000 homes but to increase it to 600,000, which would take care of the whole city of Seville.
