Electrical Energy

Isa Garcia

Electrical energy is energy that is produced or caused by moving electric charges. It is also a type of kinetic energy because the electric charges are moving. The faster the electric charges are moving, the more electric energy they are carrying.

Electrical energy is generated the same way; the starting form of energy does not matter. Some examples would be a lamp being plugged into a wall outlet. The electric current moves from the wall outlet into the light bulb. Also, another example would be batteries in a cell phone. The battery supplies chemical energy to electric charges, and the

electric charges use the energy to be put into motion. That electrical energy then travels through the phone supplying the phone with electricity. Regardless of the starting form of energy, that energy is used to give electric charges energy of 4 motion, which is electrical energy.

Electricity is also useful as a way of transferring energy over long distances. It is very important to the Internet, computers, televisions and many other devices of that use. Electricity can also be converted into other forms of energy for use of other needs. When an electric current flows through a conductor, it generates some heat. The amount generated depends on how well the material used conducts electricity. A good conductor, such as copper, produces very little. Because of that, copper wires and cables are commonly used to transmit electricity.

When heat is produced, energy is lost, so a good conductor slows down energy loss.

Materials that do not conduct electricity as well, produce more heat, so they are used more in electric heaters, cookers and Computer Board ovens.

Electrical energy is measured in Joules, which is used for both work and energy. As one saw before, there are many uses to it. Even just electricity is used worldwide. If two electrically charged objects are put close together, they will experience a force. If the forces are the same, the objects will push away from each other. That type of attraction or repulsion is called the electromagnetic force, and it can create a flow of energy. Since opposite charges attract one another, electrons will flow from a negatively charged area to a positively charged one, creating an 5 electric current.

Energy Conservation Isa Garcia

Energy conservation is basically energy consumption but using less of it. For example, driving less is an example of energy conservation. Driving the same amount with a vehicle that has higher mileage is an example of energy efficiency.

Energy conservation and efficiency are both very similar because they are energy saving or reduction techniques. Even though energy conservation reduces energy services, it can result in increased environmental quality, national security, personal financial security and higher savings. It also lowers energy costs.

Everyday Electrical Energy Everyday Electrical Energy Caro De Laurenzio

These days, people use electrical energy from the time they wake up. Setting alarms, turning on the lights, and watching the news on TV all consist of electricity. People use electrical energy to be entertained. Watching series on Netflix or listening to music on phones. Students use their computers to make presentations and write notes, all of these consist of electrical energy.

Even if people don’t realize it, electrical energy is everywhere. Electricity is generated at a power plant and travels to transformers, lowering the Electricity for a functioning voltage that distribution house and for TV systems can handle.

After that, electricity travels to local distribution systems to individual homes.The only flaw in this process is that some electricity is lost in the process. This is why some people use natural resources to produce electrical energy.

Waking up to make our first meal of the day consists of using electrical energy. From getting milk from the fridge to toasting toast in the toaster. The toaster works by transforming electrical to heat energy. The device is plugged, an electric current runs from the wall socket down the wire, and into the appliance. The toaster uses infrared radiation to heat a piece of bread.

Phones, email, and wifi is all used for communication. For these to function they need electrical energy. Using phones to call an uber or to order postmates.

Electricity for Communicating

People all around need phones to work, call, send messages, and keep a calendar. In order for all these factors to work,wifi is needed. So on with the cycle. All of these needs we have consist of the use of electrical energy.

Renewable and Nonrenewable Caro De Laurenzio

With any type of energy there are renewable and nonrenewable resources. Renewable resources are sources that are generated from natural resources. While non-renewable resources are limited in quantity and only last for so long, plus they are not environmentally friendly. With electrical energy there are plenty of renewable resources. Some are; sub, rain, and tides. There are also variations for non-renewable resources. Such as; fossil fuels, natural gas, oil, and coal. For renewable resources solar panels and windmills. To get non-renewable resources people have to dig down the Earth. Hopefully, throughout the years new renewable resources will be created and will be able to sustain all the amounts of electricity humans use a day. That will be a challenge to complete.

Electrical World

Clau Scheuren

Electrical energy is used around the world in several forms, and in different countries. We have already learned about electricity in the United States, but how about everywhere else?

China is known to be a massive consumer of electricity, using it to in high-speed railway systems, technological gadgets or in high-rise buildings. Last year, China itself built 23 million cars, trucks and buses in plants that are large consumers of electricity. They produce building materials, solar panels, trains, Electric Trains ships, plastic trinkets, smart phones and millions of more used for themselves and the rest of the world.

All of this requires a lot of electrical power therefore the reason behind being the largest consumption of electrical energy.

Russia is also seen as a large consumer of electricity, being third on the list after China and the United States. Much of the conventional fuel produced in Russia is burned to produce electrical power. Consumption of electric power divides into 12

the following: industrial takes up 61%, residential 11%, services sector 11%, transportation 9%, and agriculture 8%.

India is yet another large consumer of electricity, taking 5th place in the countries that use the most electrical energy.

India uses most of its electricity on power Moscow, Russia generation plants, with 4.8% global share in electricity in the year 2013.

With the many countries in the world that use electricity in all sorts of ways, it is no wonder that the number for consumption reaches the billions.

Today electricity finds use in many ways all around the world.

The top consumers of electricity by country are China, United States, Russia, India, and Japan.

Fun Facts Clau Scheuren

Once electrical energy leaves its source, it is instantly transformed into a different kind of energy.

It is considered a secondary energy source because it has to come from another form of energy. A natural form of electrical energy is lightning. It has been around for centuries but was put into use in the 19th century. Electrical energy is the most used source of energy.
