Before I start I have a question for you. Firsly, you should turn of the light, television and other electrical appliances when you don’t use them. Secondly, don’t forget to turn off the taps while we are brushing our teeth, washing our face or getting a shave as we can save up to 5 liters of water per minute. Thirdly, having a shower uses much less water than bathing in a bathtub, so try to take a shower every time you can. Another tip is to run washing machines and dishwashers only when we have enough dirty clothes and dishes for full loads. Apart from that you should choose energy-efficient appliances for your house. Lastly , i think you should Stock up firewood instead of turning on your heater in the winter.if you can do these things. you not only saving energy but also protect our environment.Do you have any other tips?
