Fuel_Renewable_And_Non-Renewable_Resources

Fuel Renewable And Non-Renewable Resources There are many diffirent types of fuels. Anything that burns can be called a fuel, although "fuel" usually means materials that are commonly used as fuels. Wood, coal, natural gas, and gasoline are all examples of common fuels. Fuels are usually classified as solid,liquid, or gaseous. Solid fuels, such as coal can be stored in big piles and moved in tank cars, or pipelines. Gas fuels may be kept under pressure in extra-strong containers. They may be changed to a liquid for transporting in tanks, or they may be sent thousands of miles through pipelines as a gas. Today, burning fuels-mainly coal, oil, and gas are still used for heating and cooking. They are also used in enormous amounts in powerhouses and to drive automobiles, ships and airplanes. The burning of so much fuel has resulted in air pollution in many places, and in the threat of a worldwide fuel shortage. As fuels are used up at ever-growing rates, scientists and engineers are working to develop other possible sources of heat to meet the worlds needs.
