When the sky is clear and there is no cloud around, we can feel the warmth of the sun. That heat has many uses for all living creatures on earth. Trees and plants thrive on it and people like it. People use solar collectors, the dark rectangular panels pointing towards the sun to collect the rays. The heat is absorbed and used for heating houses, water and for electricity.
The sun will always come up to give light and warmth. The heat can always be collected as long as there is no environmental pollution. The solar energy can be used as an alternative source of energy. It is inexpensive and limitless.
