This 2-page fact sheet is available in English and is intended to provide awareness to the use of energy and its impact on health. The intended audience includes public health professionals, educators, as well as environmental health specialists. Energy is the fuel for everyday living. Energy is essential to health, development and livelihoods — whether used inside the home, for cooking and heating, or in our cities and towns, for transport and productive activities. Yet energy use can also be harmful to health — particularly in poor societies where inefficient or inappropriate methods of heating, cooking and transport may degrade home and community environments, and have severe impacts on health.
