Sources Of Electricity Essay

3664 words - 15 pages

In order to explain what is electricity, first we must start off with talking about an atom. An atom is made up of protons neutrons, and electrons. The protons (positive charge) and neutrons (neutral charge) form the nucleus, while the electrons (negative charge) orbit around the nucleus. The atom is considered balanced if the protons and electrons are the same. But, if the atom loses or gains an electron it becomes an unbalanced atom. Losing electrons makes the atom have a positive charge because there are more positively charged protons than electrons. Gaining electrons make the atom have a negative charge because there are more negatively charged electrons than protons. Since there’s a missing electron, either the electron that was lost looks for another atom with a missing electron to join or the atom with the missing atom will look for a lone electron to pair join to it. The transfer of electrons is what causes electricity. When the electrons move from one atom to another they create a flow or current of electricity. Scientists are able to purposely make atoms lose their electrons, so that they make electricity. (www.energyquest.ca.gov)
There are many different sources to create electricity. Some better than others for various reasons but all the major ways to make electricity are nuclear fission, nuclear fusion , solar panels, oil, coal, wind turbine, tidal energy, biomass, natural gas, geothermal, hydro-electric, magnetic, and fuel cell.
Nuclear fission involves taking a Uranium atom and splitting the nucleus in half, which then creates a lot of power. (www.energyquest.ca.gov)

Pros
• Doesn’t require much fuel to do
• Creates very large amounts of energy
• No air pollution
• Uranium can be found anywhere
• We are not going to run out anytime soon
• Cheap to operate
Cons
• Making the power plants is expensive
• Dangerous
• Having to keep and store waste.
Nuclear fission plants should be put near the ocean and the city using the electricity, but should still be built a safe distance away. States having lots of populated areas but still have lots of unpopulated land and have large rivers or an ocean are the best and safest place to be located. Nuclear power is one of the more costly electricity sources due to cost of building the plants, storing or getting rid of nuclear waste, etc… The price is 11-14 cents per kilowatt hour. If some radiation was to escape the nuclear power plant it would cause havoc on the environment. Not only this, but having to put spent rods and storing them can cause problems too. They are highly toxic and can cause some radiation to be given off to the surrounding wildlife and people. You can transfer nuclear energy but at a cost. It’s very expensive to transport and is very risky and dangerous. Not many people would be happy to have a nuclear power plant near them. It’s understandable. Meltdowns can happen and if they do, you are at risk for radiation poisoning.
Nuclear fusion is...

Supporting the Expansion of the Darlington Nuclear Facility

1011 words - 5 pages The issue examined in this research paper is the expansion of the Darlington Nuclear Facility as a means of generating more electricity in Ontario. There are many problems and differences of opinion concerning the expansion of the facility. Many are opposed to the expansion due to safety concerns. They worry about the safety of the employees, the environment, and the public. They believe renewable sources of energy are superior alternatives to

2787 words - 12 pages know that power will flow to it. Though, the electricity that powers the light has to be made out of other energy sources. For instance, fossil fuels such as coal can be generated into electricity. Electricity can be produced from many different energies such as coal, hydro, oil and nuclear. Electricity is an important part in our daily lives which is why we must try to conserve electricity whenever we can because non-renewable energies like

Solar energy comes from sunlight, solar panels can turn sunlight into electricity. Out of these five energy sources, nuclear energy would be the most efficient source for producing electricity. First of all, nuclear energy would not emit dangerous gasses into the atmosphere when it

The efficiency scale of power plants had decreased and it is now possible to transport electricity over large distances without the loss of power. Another new trend was the use of natural or renewable energy sources, projects that are in many cases of a limited scale and private owned (Steiner, 2000).All this has led to a recent trend of denationalisation or

Geothermal energy can be used to heat buildings or water and to power turbines to make power. Wind energy can be used to pump water and generate electricity. Solar energy is of the most resourceful sources of alternative energy. It is the most important of the non-conventional sources of energy, because it does not pollute

This proves that the Darlington Nuclear Facility, in comparison, is a far more reliable source of electricity. Secondly, the operational costs of the facility are at – or below – the same cost of the alternatives, meaning it generates more electricity than renewable sources at the same costs. Therefore, expanding

Although in Cayman Island there are no more polluting industry but any increase in level of these greenhouse gases elsewhere will also harm the beauty and life of our island. Future of our Island needs to have more reliable, sustainable green electricity generated on the island itself, by using renewable energy sources like wind, solar or biological power. Cayman Island has natural potential to become world’s First country to
