Energy creates the power to drive tools and machines, to process materials into manufactured products and to create structures.

Power is generated from nonrenewable energy sources such as coal, oil, and gas, or can be generated from natural resources such as geothermal, solar, and gravitational energies.

Fossil fuels – coal, oil and natural gas -- currently provide

more than 40% of all the energy consumed in the world,

nearly two-thirds of the electricity, and virtually all of the

transportation fuels. Moreover, it is likely that the nation’s

reliance on fossil fuels to power an expanding economy will

actually increase over at least the next two decades even

with aggressive development and deployment of new

renewable and nuclear technologies.

Fossil fuels

LOGOFossil fuels

* In a fossil-fueled power plant, heat, from the burning of coal, oil, or natural gas, converts (boils) waterinto steam (A), which is piped to the turbine (B). In the turbine, the steam passes through the blades,which spins the electrical generator (C), resulting in a flow of electricity. After leaving the turbine, thesteam is converted (condensed) back into water in the condenser (D). The water is then pumped (E)back to the boiler (F) to be reheated and converted back into steam.

Coal is one of the true measures of the

energy strength of the world.   One

quarter of the world’s coal reserves are

found within the United States, and the

energy content of the nation’s coal

resources exceeds that of all the world’s

known recoverable oil.  Coal is also the

workhorse of the nation’s electric power

industry.

Natural Gas usually associated

with petroleum deposits, consists

mostly of methane, but it also

contains significant amounts of

ethane, propane and butane.

composed mostly of compounds

called hydrocarbons that contain

carbon and hydrogen.

* In a thermal power plant, steam is produced and used to spin a turbine that operates a generator. Shown here is a diagram of a conventional thermal power plant, which uses coal, oil, or natural gas as fuel to boil water to produce the steam. The electricity generated at the plant is sent to consumers through high-voltage power lines.
