The traditional, non renewable form energy is created by fossil fuels, such as coal, gas, and oil. The process begins at a power plant (primary energy source) where, heat exerted from burnin, are transformed into electrical energy. This creates high-pressured steam to form a turbine, which allows a rotor to power the generator. There an electrical current is created through the process of induction, by spinning an electrical current and conductor around each other. There the electrical energy or voltage is sent through a series of transformers, where various circuits until it reaches a building.
Another non-renewable form of energy is nuclear power. It operates the same as a traditional powerplant up till the process of induction, except uranium rods replace coal, gas, and oil and water is used in this process as a cooling system. Once the uranium atoms separates it emits large amount of heat. This fission is electrical energy, which can be stored in special containers built casing the system. This continues until uranium can no longer separate its atoms and the rods need to be replaced.
Solar Energy is an alternative electrical energy source. Its a renewable source, because of its abundant supply and limited environmental impact. Solar energy has the ability to power buildings, electronic devices, and spacecrafts through a specific process. The energy is harvested from the sun to made usable, thus it is a renewable form of energy. Solar energy is created by the use of solar panels, a collection of photovoltaic cells (solar cells, that mean light and electricity). The solar panels have a system in which, it collects the sun’s rays and converts it into energy (similar to the organic process of photosynthesis in plants), and sto...

Its most known process of generating electricity would be movement of air through wind turbines. Wind power has two parts, mechanical and electrical systems. Mechanical systems are low speed and are used for mechanical tasks such as pumping water or grinding grain. Electrical systems are high speed and are used to generate electricity to power homes or schools. Many people feel that wind farms full of turbines, are aesthetically unpleasing, but wind power is a clean energy source and does not generate greenhouse gas emissions. It is a very abundant resource throughout the United States. Wind power is simple, relatively cheap, and low maintenance (Sambu). Wind power is again, free and very abundant so no matter how much we use now, we will still obtain enough in the
Solar energy is energy taken from the light that reaches earth's surface from the sun. There are four different kinds of solar energy, which are active solar systems, passive solar systems, photovoltaic cells and concentrating power systems. An active solar systems is a system that captures solar energy by mechanical means. Common active solar systems are often in buildings or homes. Some examples are roof collectors and water heating. Low Intensity and high variability have limited the use of active solar energy in Canada. A pass...
Energy is undoubtedly one of the most important issues facing the world today. While fossil fuels may produce enough energy at a low cost, they also have severe environmental impacts on the world. Wind energy is a clean source, but is also extremely expensive to maintain. Nuclear energy may be the best energy alternative to coal and oil, with the ability to produce much more energy at relatively low cost, while also being more environmentally sound. Nuclear Power comes from the process of splitting Uranium Atoms (also called fission), which in turn releases copious amounts of energy in the form of heat.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
Alternative energy does not focus on the burning of fuel, nor the nuclear process. Alternative energy is basically an alternative to fossil fuel. Fossil fuels include coal, oil, or even natural gas. One day coal and oil will eventually run out, and the cost of these are getting more and more expensive by the day. We can reuse alternative energy, but no matter what energy sources we use, there will always be pros and cons.
A. Attention Material: Have you ever thought about energy? Where it comes from and how it powers things? Nuclear energy is one of the many types of energy sources in the world today. It is a non-renewable resource such as coal and natural gas. The first nuclear reactor ever created by man was built in December of 1942. The discovery of building a nuclear power plant was discovered over 150 years ago (Nuclear Power: Villain or Victim?, p. 15).
Nuclear energy is produced from the splitting of millions of uranium atoms in a very interesting process called fission. This type of process is used in big power plants where there are numerous tools and machinery that help produce the energy. From generators to pumps to turbines and transformers there are up to 12 main components that all come and work together to create high amounts of electricity. The fission process is used to produce a lot of heat and steam from the reactor where uranium rods are placed. That very hot steam then travels to big turbines and spins them through the generator to generate and produce high amounts of electricity. The electricity then travels to transformers and from there it travels through land wires that run hundreds of miles into cities and towns (World Nuclear Association [WNA], 2014).
Electricity is the most famous and common use of nuclear power. In most countries nuclear powers more than 10% of their electricity. The U.S. with 100 atomic reactors create 19% of our power, and 30% of the electricity around the
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
Nuclear energy is the energy from the fission or fusing of nuclear atoms, the most common being uranium atoms. This energy source is the largest provider of carbon-free emissions for creating electricity. Being such a reliable energy source, it's no surprise that there are already states and countries relying on nuclear energy to provide a large percentage of their energy needs. Nuclear plants also only need to stop producing energy every 18-24 months, and that's just to refuel. Many brilliant minds approve of nuclear energy and there are studies ongoing to make this energy source even more eco-friendly, reliable, and accessible. Nuclear energy plants currently provide 20% of America's energy needs currently, and that amount should definitely be increased in the next decade.
I am certain that all have heard of the terms greenhouse gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008).
There are different kinds of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from natural resources. Although renewable energy can be expensive to build, it has less environmental damage in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources.
There are two types of resources using to produce electricity, non-renewable energy resources and renewable energy resources. Non-renewable energy resources or known by fossil fuel such as wood, oil, gas and coal can be defined as solid, liquid or gaseous fuels formed in the ground after millions of years by chemical and physical changes in plants and animal residues under high temperature and pressure.
Energy can be put into two broad categories Renewable energy and none renewable energy. Renewable energy sources can be reused continually as they are abundantly found in nature. All of them are non-polluting but devices used to collect the energy may impact the environment adversely. They are free but producing storage equipment or converting them into another form of energy may be costly.
