Almost every aspect of our lives involves energy. Energy lights up our cities, powers our vehicles and runs machinery in factories. It warms and cools our homes, cooks our food, plays our music and gives us pictures on the television. When we eat, our bodies transform the food into energy to do work and carry out life processes.
Almost everything we do requires the use of energy from fuels, water, wind and others. However, the increased use of these energy resources is causing environmental problems around the world. Besides, these resources do not last forever. Hence, we need to use energy and other resources wisely. By doing so, we can make sure that the environment is not harmed and future generations can use the resources to meet their needs. We need to be aware that we must take responsibility to conserve energy.
