Q. The process below shows how drinking water is made using solar power. Write a report for a university lecturer describing the information given below.

The given process chart illustrates how underground water is pumped out and made fit for drinking by using energy from the sun. It can be seen that mainly four steps are involved in the process.

In the first step, heat from the sun is accumulated using solar panels. This is then converted into electricity. This electricity is then used in a pump that pumps underground water. After this step, the pumped water passes through a water filter and is then stored in a large water tank that placed on a wooden platform.

In the next step, there is an outlet pipe on the lower end of this water tank which has a tap attached to it from which potable water can be taken out in a movable container as and when needed.

Overall, it can be seen that solar energy, which is renewable energy, can be used very efficiently to pump water out of the ground and then filter it into safe drinking water.
