All in all, using less energy, using energy-efficient lights, and using public transport are three principle ways to keep our energy clutter-free. One of the unmistakable measures is to use less electricity. We should save energy by turning off all devices before going out or going out. We cannot exist without energy. There are three obvious ways to save energy. Even so, we don't use energy properly and it slowly gets limited. Thus, our electricity bill will be reduced when using. Finally, we should use public transport or walk instead of going by motorbike or vehicle. This is actually great for our current situation, and it's especially prudent.
