In the next fifty years, energy supply will become a major issue all over the world that natural resources will nearly be exhausted, such as fossil fuels.There are two kinds of energy, which is depleted energy and renewable energy. Alternative energy has become considerable options for mankind to seek for sustainable energy. This essay classifies alternative energy based on their source into three types, which comes from sunlight, wind, and nuclear. One type of alternative energy is solar energy. The sun is the main source power of solar energy, which is transform into electrical or thermal energy (Solar energy, n.d.). There are three kinds of solar energy that is solar thermal energy, photovoltaic solar power, and concentrating …show more content…
A wind turbine looks similar to a fan that the wind turns the blades to spin, then it will create electricity (Wind energy basics, n.d.). There are two principal kinds of wind energy based on a horizontal axis and a vertical axis (Meyers, 2013). According to Meyers (2013), a horizontal axis has to encounter with the wind, so blades can spin and generate electricity from the top of a tower, and a vertical axis does not necessary to directly face wind. One study revealed that larger winds are able to distribute bulk power, and the costs are justifiable (Wind turbines work, n.d.). The notifiable advantages of wind energy are unlimited and substitutable resources, and also increased economy, cost effectiveness, and harvesting facilities (Lloyd, 2014). Other benefits of wind power are installed in a small-scale space, increased a great deal of employment rate, and non-polluting undesirable gases (Silva, 2014). Furthermore, technicians who work with wind solar have to wear a uniform properly, such as hard hats, harnesses, and safety goggles before go in a turbine (Wind turbine technician, 2014). One study showed that there is a remarkable health and safety record of the wind energy over past 20 years that there are more than 100,000 devices provided worldwide, and also none workers who got injuries from the machines (Wind farm safety, …show more content…
Nuclear power is included several atoms (Nuclear power, 2015). Nuclear power has two sorts, which is fission and fusion that a large amount of power form are accumulate in the atoms of numerous components (The ten types, n.d.). This will convert to energy based on suitable conditions. Additionally, the beneficial of nuclear energy is to created jobs, and stimulated economic growth (Costs and benefits, n.d.). It also referred that in the United States, electricity sales and revenue have rise from 40 to 50 billion dollars every year. One study of CNN news reported that in the United States, the 103 nuclear industry has generated electricity for over 20 percent since 1978 (Roderick, 2013). Moreover, nuclear energy is not only a primary global energy source, but also the largest source of free electrical emission (Benefits Nuclear Energy, n.d.). In addition, the meaning of nuclear safety is the accomplishment of avoided nuclear accidents, protected workers, and against dangerous impacts of radioactive material and ionizing radiation (Nuclear energy, n.d.). Other study of CNN, There was a proof that the safest form of alternative energy is nuclear power in the United States over past 50 years (Roderick, 2013). Another study found that commercial operation recorded that nuclear power is not harmful because it collected experience of over 12,000 rector for many years (Comby, n.d.). In conclusion, this essay has divided
Power plants burn fuel to produce heat to generate energy; however, nuclear power plants use the heat given off fission to turn water into steam. Nuclear energy is without a doubt a great way to power our homes because, Nuclear power plants are safer than other energy alternatives. Nuclear plants are safer than other energy alternatives. Coal is responsible for five times more deaths than nuclear power plants, coal also causes over one thousands more serious causes of illness than nuclear. Nuclear plants produce steam while coal plants, heat water by burning coal that produces greenhouse emissions.
In “Nuclear Power is Not the Answer,” Helen Caldicott argues that pursuing nuclear energy would be a detriment to the United States. According to Caldicott, nuclear power, contrary to what the industry claims, is not clean and green, but rather a pollutant and a strong contributor to the destruction of the ozone layer. Because of the availability of uranium ore steadily decreasing, the process is requiring more and more fossil fuels to extract the ore. Caldicott projects that within ten to twenty years, nuclear reactors will be counterproductive because of the amount of fossil fuel it will take to mine the remaining uranium. In addition to air pollution, nuclear power plants also emit radioactive gases and materials that have the potential
What do you think about nuclear energy is safe or not? Do you know why nuclear energy is important to us? And do you really know why we need to have this kind of energy? After my speech, it will make you to understand why we need to rely on this kind of energy.
Over 20 percent of the energy in the United States comes from nuclear energy power plants. (Rinkesh, 2018) They so their best to get as much energy to the country as possible, but there are those out there who don’t agree with them. While there are downsides to nuclear energy, the pros vastly outweigh the cons. Nuclear power plants are a great way to get energy because they don’t let out much pollution, are very efficient, and are very safe.
Nuclear power produces fewer carbon emissions than traditional energy sources because energy is not produced by burning molecules but splitting atoms. ‘An energy mix including nuclear power has the lowest impact on wildlife and Ecosystems’ as shown by a Conservation Biology paper. Consequently, greenhouse gas emissions have reduced by nearly half which shows the benefits and popularity of nuclear power use. Nuclear power has many environmental benefits such as small waste production, leaves no adverse effect on water, land or any habitats. By reducing fossil fuel consumption and switching to Nuclear Energy, we will sustain the environment, quality of air, improving the overall quality of
Chernobyl, Ukraine. April 26, 1986. A nuclear reactor had exploded due to poorly trained workers and a badly executed monitoring procedure. It took over 600,000 emergency workers and firefighters to end the madness. By the end, 63,000 square miles of land were impacted and could not be used for crops.
Nuclear energy has numerous world benefits that other forms of energy creation just don’t, and its pros are truly unprecedented by any other source of energy. Nuclear power plants are inexpensive to run, which means they can easily be maintained and sustained at a low cost. And while the reactors themselves may be expensive, with government grants the materials can be much more easily purchased and built. The most expensive part of the nuclear reactor process is the uranium, which again, isn’t hard to get as it’s used in few other applications and can be acquired through government programs. Additionally, the energy emitted from these power plants compared to their cost is immense and an extremely worthwhile investment for governments and private businesses.
Nuclear energy may be the solution that eliminates our concern for energy production in the future, but it still remains a huge issue for the environment. Despite its wide use in many developed countries, nuclear energy poses many threats to both the
You may think that solar energy isn’t enough but we can use it with other clean energy. It is a wise choice to use solar energy because solar energy is renewable and abundant, it is environmentally friendly, and it is also available around the world. Solar is the most abundant energy resource on Earth. In Taiwan, a three-story building with solar panels can produce three to four families’ electricity.
Nuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).
Scientists have found that renewable energy is a path towards the future for a clean and safe environment. Throughout all the studies and findings, there is a continuing fret whether people should be able to use a traditional way of energy or renewable energy, solar power. Solar energy is seen to be effective since there has progressively been more places that are benefiting from solar usage; however there are also some who disagree. Solar energy sources are derived from natural sources and is implicated throughout our daily lives. From the lights in the streets to the computers we use at home.
Wind energy is mainly used to generate electricity like earlier wind mills modern wind machines used blades to collect the winds Kinetic energy. 1.1.1 Advantages 1) The blades ere connect to shaft that turn on an electric generator to produce electricity. 2) Use of wind power to produce electricity on commercial scale has become the fastest growing energy technology. 3) Wind energy is comparatively labor exhaustive and as a result creates
How Technology has changed the World I. Intro a. Over time humans have destroyed the environment with pollution and now we are creating new technologies to spot polluting our planet. b. Technology is rapidly evolving and it has changed the way people live out their lives. People have become attached to technology and it is affecting the way we live both physically and mentally.
wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources
Nowadays, we usually use the newer term called “wind turbine”.1 About four percent of the energy created in the United States comes from wind energy,2 and over 100 countries are now following in this trend and produce energy through the use of wind. This not only shows that a wind energy has great potential in the future, but also how popular it already is. It can be said that the more countries there are that using wind energy the better it is for our world. It is better because wind energy is a sustainable energy source.3 Looking back already at around 1000 AD wind power used and spread around northern Europe, starting with Holland.
