We can save energy by doing some following tips. First of all, we should use electricity more efficiently and reduce our electricity bill. We need to turn off the TV when we are not watching, turn off all the lights before going to bed. Besides, we should not leave the fridge door open in a long time due to wasting of electricity. Moreover, we should save water by taking showers instead of baths or turning off the water when you don not use it. The next tip is reducing the use of fossil fuels like gas, coal, and oil. It is not only saving energy but also protect our environment. To do this, we can use public transport and avoid using car or motorbike for short trip. All in all, because our energy is limited we need to reserve it for the future generations.
