The correct answer to this open question is the following.
The two ways on how I can apply prudence and frugality on consuming energy, plastic, water, and paper, are the following.
1.- Being responsible. Only turn on the lights when it is completely necessary. No lights during the light of day.
2.- Being conscious. Many people in different parts of the world have no fresh water at all. They have to walk long distances to get some water and take it to their towns and villages.
I drink the necessary water on a daily basis and waste no more. I am going to take five-minute showers. No singing and wasting precious time.
I can save paper now in the digital world. Stopping consuming plastic and paper mean that more raw materials and natural resources will be safe.
