The Advantages And Disadvantages Of Tidal Energy And Nuclear Energy

Wind energy is another renewable source of energy that could be a potential alternative energy source. “Wind power is the conversion of wind energy into a useful form of energy such as using: wind turbines to make electrical power, windmills for mechanical

Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.

There are limited negative impacts on the environment; wave energy harnessing devices have the lowest potential impact

One of the effects with the most impact from the use of fossil fuels is the pollution created. The United States, per the study conducted by WorldBank, is recorded as being the 10th largest contributor of carbon dioxide in the world per capita. In one year producing 17.6 metric tons, another unfathomable amount (Table). In order to dramatically cut this amount of pollutants down, another source of energy must be utilized. Today, there are many potential options available. Three of the most promising are wind, solar, and tidal energy. Solar is energy obtained from the sun, wind is energy generated by spinning

For renewable sources of energy it is the most reliable even though it is variable. Different power generation methods have finite resources that will eventually run out. Other renewable energy resources while powerful are either unreliable such as wind are not always available such as solar energy. Through the use of dams we can store water to be used when needed to supply the demand caused by energy consumption. Using gravity water is allowed to flow through a turbine causing a generator to make electricity. When demand is low the water can be pumped back up into the containing reservoir to make another hydroelectric head. This process can just be continued creating a reliable capacity of energy. In the use of tidal power generation electricity comes in and out with the tide. There is a small marginal effect on the environment because no emission or hazardous waste is being made. While most prime locations for traditional hydroelectric power plants are already taken, there are plenty of locations to be used for tidal power generation. Once the technology to build underwater structures that are able to last against the harsh waves is more manageable there will be plenty of new location ready to be taken throughout the ocean. These generation plants will just be using water and gravity to supply power to meet the ever growing demand of the population. Using water to it full advantage in every facet possible from traditional hydroelectric pumped storage, run of the water types, tidal barrage using shoreline bays and tidal current using the oceans current will make it the greatest resource on

Similar to wind power, tidal power is careful to be a possible foundation of renewable energy since tides are stable and foreseeable. Much similar windmills, tide mills have been castoff since the days of Ancient Rome and the Middle Ages. Incoming water was kept in large ponds, and as the tides went out, they twisted waterwheels that produced mechanical power to mill grain.

Waves are produced by winds blowing across the surface of the ocean. However, because waves travel across the ocean, their arrival time at the wave power facility may be more predictable than the wind.In contrast, tidal energy is driven by the gravitational pull of the moon and sun. Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the ocean [29][30].Tidal power has a relative advantage in that it can generate power from

Nuclear power is a very intriguing alternative energy source. I find that the more that I learn about nuclear power, the more I realize that my knowledge has just skimmed the surface of what there is to know about the energy source. The most surprising fact about nuclear power that Mycle Schneider mentioned in one of his interviews was that all nuclear reactors have a life expectancy. On average, the typical nuclear reactor has an operational design basis of approximately 40 years. As of right now, the average age of all operational nuclear reactors worldwide is approximately 28.5 years old. This means that within the next decade, we could begin to see the majority of these nuclear plants being decommissioned. Therefore, when the time comes,

In the world today, we consume ungodly amounts of fossil fuels. Many choose to ignore that we will indeed run out of these fuels, as for now they are here and they are cheap. So what happens when they run out? We will need to rely on alternative forms of energy. There are several types of alternative energy sources such as wind, geothermal, solar, and tidal. Of these in the current day, the easiest one to predict is tidal power. Tidal power, in Tom Marsik’s words, is in its “infant stage of development.” Tom Marsik is a professor at the University of Alaska Fairbanks Bristol Bay Campus who runs the Sustainable Energy Program and has a doctorate in physics. From his description, it is not cost effective for many places in its current state. The technology is there, but it has not been refined and mastered. All this considered, tidal power should be a technology that continues to be developed because it is predictable, renewable, and highly efficient.

Wave and tidal energy harnessing are becoming a new viable potential form of alternative energy. New innovations with increasing advancements in technology are rapidly changing the course in the production of a clean, pollution free, and efficient use of energy through the consumption of the one of the world’s largest natural resource, the ocean.

This is one of the most important factors for any possible future source of energy. Tidal power does not require any fuel and therefore does not emit any greenhouse gasses into the atmosphere. The effect on our environment however, also has some downsides. Tidal turbines could disrupt the movement of large marine animals and ships through certain shipping lanes. The construction of tidal power plants could disrupt fish migration and could kill fish when passing through the turbines. These are all possible drawbacks of tidal energy. The actual impacts of tidal power are very uncertain as this particular source of energy has not been deployed and tested in our ecosystems yet. Popular believe has it that tidal power is not renewable as extracting power from the tides slows down the earth’s rotation and that therefore tidal power is not a long-term energy source. However, this is not correct. The natural tides already slow down the earth’s rotation. Tidal energy extracts energy that otherwise would have been lost in any case. Even if we doubled the amount of energy that we would extract from the tides, tidal energy would still be able to last for the lifetime of the

Geothermal Energy The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros and cons.

Currently, in the 21st century, we face a multitude of problems regarding the safety and well being of our environment and ecosystem as a whole. For hundreds of years, people have been creating energy, unaware of the irreversible damage and the harmful effects it can have such as climate change and the greenhouse effect. Because of this, people have begun to stray away from the burning of fossil fuels and now rely deeply on renewable energy sources such as sunlight and wind. But with all these more modern ways of manufacturing energy becoming increasingly much more popular, nuclear energy has controversially become an option for many areas in the United States and also the world. This form of energy production has various different advantages such as its proficiency against fossil fuels and low pollution. Despite this, nuclear energy, in fact, is more harmful to the globe as it has many safety concerns and creates issues of where to dispose of nuclear waste.

Imagine this, there is a huge rarely used energy source that if tapped can solve the energy needs of entire cities. Nuclear energy is energy produced from the uranium 235 the uranium goes through an extensive system of steps and equipment turning it into nuclear energy. First, water is pumped into a box and uranium is a similar box next to it, but it has control and fuel rods inside to make sure the uranium stays in check. Secondly, it becomes steam from the heat of the Uranium, which also gives it the potential to create energy, and then it goes through a turbine and into a generator. The energy comes from the steam when it makes its way into the generator. The rest of the water that does not turn into steam goes through a circuit to another box with cool pipes and hot pipes. Once there, it is all turned into steam as it enters the hot pipes. The steam goes through the hot pipes and into the cooling tower. At the cooling tower, it cools off and becomes once water again. With the information just stated the reader should now have a little understanding of how nuclear energy works from the inside. In this paper, the reader will learn further about how nuclear energy can be clean, how it takes up a lot of space, and how it can be extremely dangerous.

“‘Climate change’ refers to any long-term change in Earth's climate, or in the climate of a region or city. This includes warming, cooling and changes besides temperature.” (NASA Oct.2011) Earth is going through the climate change of global warming. Climate change is causing a big threat that would cause great catastrophe to the world and this problem will influence everyone around the world. These changes are caused by the greenhouse gases which are produced when burning fossil fuels and transportation. When fossil fuels are burned, they generate a fair amount of energy for people, but at the same time, produce large amounts of pollution that damages our Earth. To slow down climate change, we need to start making changes and shift our sole energy source from burning fossil fuels to an alternative renewable energy source. While tidal energy is an interesting technology and is capable of providing us a carbon-free society, but it can never generate enough energy to reduce the burning of fossil fuels because of the massive cost for the project and there is limited places in the world to install the technology.
