Power from the sun
Among 21st century energy resources, renewable solar energy is growing in importance. Solar energy panels are becoming common sights across the landscape, powering everything from traffic lights to art installations and even aircraft.
They are ingeniously used to power communications satellites in space and extra-terrestrial vehicles such as the Mars rovers. Increasingly, they are being installed on the sides of buildings and on rooftops, reducing the demand for more traditional energy sources.
Our ability to produce solar energy more efficiently and more economically will depend on how well we apply the tools of chemistry and physics available to us. So far, chlorine chemistry has proven essential to the development of solar energy.
