Summary: Energy Resources

The heat in many other homes and businesses comes from electricity. So does the enrgy to run many common devices, such as light, computers, radios, TV`s , and washes. Some small devices such as flashlights and portable CD players get their electricity from batteries.

Electricity from that plant reaches your home throught wires. However, the power plants makes electricity by using energy

from burming fuels such as coal, oil, and natural gas. It takes

a lot of energy to move car, bus train. Public and private transportation is one of thd greatest uses of energy in today 's world. The heatcan also be used to generate electricity. The heat is used to boild waterand turn it into steam. the steam is directed at a big, pinwheel-liketurbine. Fossil fuels are the remains of onceliving things. Coal formed from the remains of dead plants buried in ancient swamps and forests. Natural gas and oil formed fromn the remains of tiny ocean plants and animals. These sea crreatures died and fell to the bottom of the ocean. There their bodies were buried by layers of sand and mud. As more and more layers covered these remains, pressure on them built up. Eventually, the layersof sediments turned   into sedimentary rock.Our supplies of fossil fuels ae limited, and fossil fuels are not a reneawable energy source. With the grownth of industry,m the demand for and use of energy also grows. 

Modern Waterwheels            

Any whitewater rafter can tell you that running water has a lot of energy. That energy can be hanessed to do work using waterwheels. Running or falling water tuns the wheel. the turning wheel spins an axle, which is attached to various machines to do work .

Harnessing the wind

Have you ever watched a pinwheel spin in the wind? Wind,or moving air, can also spin a wheel . Holland is well known for its great windmills.

Earth's Furnace

the Earth`s interior is very hot. thr most common evidence of that heat is simply hot water o steam coming out of the ground.Earth`s internal heat is called geothermal energy.

• Homes in Boise, Idaho, have been heated by hot springs since the 1890s.
• At the Geysers in California, steam drives turbines that generate electricity. The steam comes from underground water heated by geothermal energy.
