Types+of+Energy

=Non-Renewable Energy Sources= //Non renewable energy sources are not renewed easily or quickly.//

 * //Oil//** - Oil is burned to heat water to create steam to generate electricity; oil is also burned under pressure to produce hot exhaust gases to spin a turbine to generate electricity. But burning oil for electricity pollutes the air, water, and land, but some of the worst environmental woes associated with oil are linked to drilling, transporting, and refining. Oil takes a really long time to form. That is why it is a non-renewable energy source.

 * //Natural Gas//** - Natural gas is the cleanest-burning conventional fuel, producing lower greenhouse gas emisions than heavier hydrocarbon fuels, such as oil and coal do. N atural gas is from animals and plants that decomposed over a million years ago. Natural gas is a fossil fuel. Natural gas is found under ground, located in several areas of North America. It is not a renewable source because it takes millions of years to make. Natural gas is burned and it creates superheated gas which is than pressurized in pipes and used to turn the turbine to create electricity.


 * //Coal//** - Coal is non-renewable because it takes more than one hundred thousand years to form. Coal is a dirty kind of rock that can pollute the atmosphere when burned to make energy. Coal is used to produce electricity all over the world. This is the process for burning coal to make electricity. The coal is ground into a fine powder. This powder is burned which heats the water turning it into steam. The steam then turns the turbine, generating electricity. After that, the cycle begins again.

**//Nuclear Energy//** - Nuclear energy is a clean way to make energy because it doesn't produce as much pollution as fossil fuels. The steps in making energy in a nuclear power plant are: 1. Uranium rods radiate heat. 2. The heat turns the water into steam. 3. The steam moves turbine. 4. The turbine moves rotor which creates electricity with the elctromagnet. The United States has about 110 nuclear power reactors. Radioactive materials, used in nuclear energy, can be man made or made by nature. Only 30 years ago, nuclear energy was an exotic, futuristic technology, the subject of experimentation and far fetched ideas. Today, nuclear energy is America's second largest source of electric power after coal. The use of nuclear reactors to generate electricity continues to increase all over the world. By December of 1979, about 128,000 million watts were being generated by 249 reactors operating in 22 countries. Nuclear Energy is the use of nuclear reactors to generate electricity continues to increase all over the world. By December of 1979, about 128,000 million watts were being generated by 249 reactors operating in 22 countries. Nuclear Reactor is fueled by uranium or plutonium in a solid form. 17 % of the United States energy is Nuclear Energy. Other major Nuclear Energy producers are Canada, France, Germany, Great Britain, Japan, Russia, and Sweden. Nuclear Energy has advantages like it uses less energy then a fossil plant.The meltdowns are very dangerous and could cause a lot of damage to the enviroment.

=Renewable Energy Sources= //Renewable energy is created by these elements and materials: sunlight,wind, rain, tides, and geothermal heat.// //Renewable energy is energy that can be renewed quickly.//

 * //Biomass//** - Biomass is when plants and other forms of living material waste are burned by people to heat the water that turns into the steam. This steam turns the turbine which creates electricity. Modern technology has allowed us to do this without creating as much air pollution and global warming as fossil fuels. One of the forms of biomass is wood.

 * //Hydro-Electric//** - Hydro-electricity is created using water. You have to build a dam to block the water. The water blocked by the dam, then goes down a hole where it spins a turbine. The water spins the turbine creating electricity. One dam the U.S.A built is the Hoover Dam. It is renewable because we have alot of water. A total of about 15% of energy in the U.S. is Hydro-Electric energy. It is one of the cleanest energy sources.

 * //Tidal//** - Tidal is the energy source from sea and one of the oldest sources of energy. There are only 20 tidal power plants in the world! Depending on the moon, tides change. For example: the tide would be different on a full moon than it is on a new moon. The tidal turbine is like windmill flipped upside down in the water. When the water moves through the turbine, it creates electricity. As the tide is coming in, it moves the turbine and the same thing happens if the tide is coming out. We use this electricity for almost everything near the turbine.

**//Wave//** - Wave power is energy created by the motion of waves. People have thought of ways for using the power of waves at least as far back as Leonardo Da Vinci. The first invention for making electricity from wave power was by two French scientists in 1799. People started not researching wave power as much around March in 1980. Because not many people were using it.

The way wave power works is that it uses buoys underwater to pump the waves to turn the turbine, it creates electricity doing this. Because wave power uses the motion of waves, it does not make pollution. Wave power is infinite. In Japan, Great Britain, and Norway still use use wave power pretty often. A group of storms hit in 1989, causing a tower that collects energy from wave power to get destroyed.

One problem with wave power is that it is very expensive. Another is that it is hard to make. It would take years to make new buoys and other equipment. (Click here for pros and cons, links and images.)

 * //Geo-Thermal//** - Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. Geothermal energy is called geothermal energy because it has to do with or is produced by the earth’s internal heat. There are geothermal power plants located in: New Jersey, Florida, Pennsylvania, New Zealand, and Delaware. The heat from the Earth turns water into steam to turn the turbine to make energy to make electricity. (See image on other page.)

=Infinite Resources= //Energy sources that may be used without damaging the Earth.//

//**Solar**// - Solar energy is <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;">used to make electricity and heat water. Energy from the sun, some places called solar farms have a bunch of solar panels and maybe mirrors to reflect the sun onto the panels to create more energy.<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;"> Solar power can also be used to power spacecrafts. It is generated by tiny devices called photovoltaic cells. It can be used to heat homes, pools, and can be transferred into electricity. Without solar energy we could not use wind or hydroelectric power. All life on earth is powered by some solar energy. It is an infinite source because by using it we are not taking it.

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;">Also, solar energy can also be used in the process of a solar furnace. The Sun is used to heat the water, then that water turns the turbine to create electricity. You could also use the Sun to heat water to use for washing things in a sink, bathtub, shower or washing machine replacing your normal hot water heater. The Sun heats the water in black pipes and then the water is used in your house. <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;">(Click here for pros and cons, links and images.)

 * //Wind//** - <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;">Wind is caused by the uneven heating of the Earth's surface by the sun. This causes different air pressures to combine. The wind blows through the windmill blades, which turns the rotor to generates electricity. Wind power is infinite because you can use it and it doesn't harm the wind and it will never go away. Wind power is usally used in fields with lots of wind.
