How Electricity is Made

Electric generators that are used within nuclear power plants are powered much like the way you power a bicycle with your legs, but on a much larger scale.  The difference is that, instead of someone pedaling furiously with their legs, heavy steam drives the big generators. A nuclear reaction creates the steam by burning the fuel.  A nuclear power plant produces a huge amount of electricity, but much of it is lost through producing the energy.  That energy goes from the nuclear plant to the factories, homes, and businesses by traveling many miles through cables, losing up to two thirds of the original power it originally created while in motion.

The power plants create the electricity through burning things such as oil, gas, and coal, also known as fossil fuels, which causes some extra problems.  Global warming is said to be caused by the contamination created through burning those fuels.  There is also the problem that fossil fuels can run out and are often restricted.

28Luckily, there are a lot of other ways that energy can be made that do not cause global warming, are a lot more efficient, and that do not pollute like using fossil fuels does.  Since these types of energy can last forever, they are considered renewable.  Solar power and wind turbines are two forms of renewable energy.  They are a very reliable source for creating electricity.  Less power is wasted as well since less travel is needed for the electricity to travel down wires due to the fact that they can be mounted closer to the place where they are needed.

A wind turbine is made using a very simple generator that has a propeller on the front.  The generator turns when the wind blows it which, in turn, creates electricity.

The batteries used in solar energy do not work through using generators or magnets, making it unlike any of the other methods used for creating electricity.  Instead, the the sun hits the solar cell, the silicon material gathers the power from the sun and directly turns it into electricity.  This makes solar power a very reliable means for creating electricity for homes and businesses.  Places with solar panels mounted on their roofing are able to produce the majority of their own electricity if they are done correctly.

 

What is Static Electricity?

Static electricity frequently happens when items rub against one another. If you were to rub a balloon against your clothes 20 or 30 times, you’ll find the balloon adheres to you. This occurs because rubbing the balloon gives it an electric charge. That charge makes it adhere to your clothing like a magnet, because your clothing gets an electrical charge too. So your clothing and also the balloon draw in each other like the opposing ends of two magnets.

After that touched something metal, like a door handle or a faucet, and then felt a pain where you touched the object? That is an example of what an electric shock is. Your feet are rubbing on the carpet when you walk across it, building up an electric charge that may cause you to feel a prickling sensation. When your body has the charge and you touch something metal, that charge runs promptly to Earth– and that is the shock you feel.

Lightning is likewise triggered by static electricity. Rain clouds move against each other as they move through the sky. They become electrically charged when they do this. When that charge is finally big enough, it bolts to the earth in the form of lightning. You could often really feel the tingling in the air when a storm is nearby. This is the electricity in the air around you.

Electrons, the small fragments that “orbit” around the sides of atoms, are what make electricity. Each electron has a tiny negative charge. An atom generally has an equivalent variety of electrons and also protons (positively billed fragments in its center), so atoms have no overall electric charge.

By rubbing a balloon on your clothing over and over, you give that balloon energy. Using your hand, you can make the balloon move. As you rub the balloon against your clothing, some of the electrons gather on your body as they are knocked off of the rubber. This, in turn, leaves the balloon with fewer electrons. Having fewer electrons then makes the balloon positively charged a little. Your clothes, on the other hand, are a little negatively charged with the electrons from the balloon. Taking those two charges into consideration, they are attracted to one another and try to come back together.
