Tag: Fuel efficiency

Fuels are materials that are burnt to provide heat or chemical energy. Fuels can be gases, liquids or  solids. There are natural and man-made fuels. Some fuels are more efficient than others. Engines are machines designed to convert chemical energy into other forms of energy and thus do work. The use of fuels has social and economic implications on society. Fuels are either renewable or non-renewable. Non-renewable fuels should be used sustainably.
