Most of your energy comes from fossil fuels like petroleum, natural gas and coal, which provide electricity and gas to power our continuously growing energy needs. However, these resources are non-renewable, which means that one day they will eventually run out.
Conserving energy not only helps to conserve resources, but also translates into financial savings. When we use our aircon systems, electrical equipment, turn lights on and wash our hands, we don't usually stop to assess the amount of resources we are using. We also don't stop to think about how we are depleting these limited resources.
