Persuasive Essay: Solar Energy is Superior!
Did you ever think about where your drinking water comes from? The water that we drink was initially sea water that has undergone a scientific process called desalination. Desalination is a chemical process in which natural compounds are separated from water, making the water clean and drinkable. Traditionally, sea water is propelled through hydraulic pumps which create a flow to separate the water from the sea salt. Hydraulic pumps require certain chemicals that are harmful to humans and these chemicals sometimes are cross-contaminated in the drinking water being produced. Personally, I don’t want to drink chemicals that are threatening to my life and that cause harm to the environment. Many people would be uncomfortable if they knew what chemicals their drinking water may contain, especially if their children also consume it. The major drinking water producers should rely on solar energy to desalinate water which is a newer, cleaner, and safer alternative energy source.
The current system of not utilizing solar energy has major consequences; one is negatively impacting the environment. Hydraulic pumps have a rather simple composition that is explained well by a website that specializes in the hydraulic pump market, hydrauliconline.com; the pump consists of two wheels that circulate via the churning of certain toxic chemicals. Between the wheels is a passage for water to flow through, then the water is drove through a filter that separates the water from salt or any other natural substances present. According to a site devoted to preserving the environment, earthworksaction.org, hydraulic pumps require certain liquid chemicals such as hydrochloric acid, methanol, and diesel fuel. All ...

...ergy is more environmentally friendly, cost effective, and can be just as efficient as the hydraulic pump system. With this method of creating freshwater, companies and workers no longer have to worry about the chance that toxic chemicals may mix in with the water being created. These same people will also not have to feel guilty about using an excessive amount of water to help their process as well as not hurting our planet. You as the consumers will no longer have to worry about consuming water that is life threatening, even if you weren’t aware how hydraulic pumps worked and affect our drinking water. I believe that solar energy is our future, and the planet will greatly benefit from the use of this green method. Even as long as 100 years ago, the ingenious Thomas Edison was quoted saying “I’d put my money on the sun and solar energy. What a source of power!”
The use of turbines from dams to provide power was a brilliant idea until water levels started running lower than normal. The water waste from humanity is directly contributing to portions of it, aside from drought conditions affected by pollution, widespread fires battled, and more adds to the depletion thereof. When humanity is relying on power provided from dams to handle the demand, they are essentially relying on the assumption that water levels will always be there to provide it. The Hoover Dam provides power to the southwestern portion of the USA that has a large number of people.
Solar Energy Life is sustained by the energy from the sun. Without the sun all plants and animals would die. The sun provides 99.98% of the energy, which naturally flows through the surface environment of the earth. Put another way, the sun supplies 5000 times more energy than all other sources combined. This emphasizes the importance of solar energy to us.
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.
Our world has seen several inventions that have greatly impacted our way of life. Of those inventions renewable energy sources is what we believe has the biggest impact to our daily routines. Hydroelectric energy is one of the biggest energy producing plants used today. Its efficiency is 70- 95% making it one of the biggest suppliers in the world and of high interest to energy companies. Based on new statistics, an unprecedented boom in global hydropower dam construction is underway, primarily in developing countries and emerging economies (Water World, 2014). Hydroelectric plants are operated by trapping a water source by building a dam and having it readily available to the plant. To produce energy the dam opens small doors at the bottom
Solar power is only one of the forms of energy. Solar power has its advantages but most of the people the people think the solar panels are expensive disadvantages, but it’s actually an advantage. Solar power starts saving money from day one. Electricity is one of the key things we need to clean up and solar power is the way to do so. (Shanan 1-4) Solar energy is a visible form of alternative energy. Solar panels capture energy from the sun’s rays and convert it to electricity. Solar power offers a clean form of energy. Solar energy carries political considerations just as petroleum does. (Linden 1-4) Virginia Water Resource Research Center has found that solar photovoltaic uses about 21 times less water than nuclear power about 16 times less water than coal power and 8 times less water than a combined cycle power plant. (Shanan 1-4) Solar power has disadvantages also. Solar panels make a ton of pollution when their built, and sun doesn't always shine on them. (Shanan 1-4) They may take several years too see a return on investments. Solar energy is not universal because different areas of the world get different amounts of sunlight. Solar energy may not offer the best solution: there distractions, they have high environmental costs and they have a large outlay of cash. There can be contamination from radio activation saved used to make solar panels. (Hinder 1-4) Installation is expensive being $80,000 for a three bedroom after the federal rebate. The angle of the roof, percentage of sunlight and the area of the country all play a part in the effect of how much it will co...
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.
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
Solar energy is very important now and will be in the future. It is useful alone but may need some help to stay reliable and affordable. Using solar energy to generate power is in a growing phase. It is becoming more and more popular every day. Solar energy systems are ready for more use across the world. Solar energy will help the environment and help people save money. Solar energy helps in many different ways but, there is more out there to catch the flaws that solar has. Solar energy has been used for a while and people need to realize that there are better options than just purely solar; one of these options is better because it has more reliability, a lower cost and a higher rate of energy production.
Solar energy is one of the useful resources, which do not impact on the environment. Today, most people use fossil fuel, which is nonrenewable and cause pollution, rather than other sources. Also, fossil fuel can make the air unhealthy by releasing carbon dioxide; therefore, solar energy is great because it is renewable energy and it is replaced. Solar energy has many uses some of them can be dangerous and some of them can be useful and helpful for the environment; therefore, there are environmental advantages of solar energy. Overall, solar energy is an alternative source and can be used in many ways: to protect the environment since it is non-polluting and clean, can be used in remote
A next disadvantage is water has lower viscosity which means decreasing in friction but can cause more leakage and erosion on the system. Due to more leakage it is leads to more power losses. They need to reduce the clearance and tolerance on their equipment. Water hydraulics was no longer a competitive source of hydraulics power transmission and ever since was superseded by oil hydraulics except in applications which are environmentally sensitive. (Krutz & Chua, 2004)
It is recommend to eliminate solar subsidies programs and find an alternative method for sustainable energy, such as batteries.
Hydroelectric Power Plant is when electricity is generated when water in an uphill reservoir flows downhill. The gravitational potential energy of the water changes to kinetic energy of the flowing water which drives the turbines to generate electricity. The efficiency is more than 90%. The environmental impact is Floods large area and affects the ecology of the area, May cause drought downstream if not managed properly, does not cause ai...
One of the most used renewable energy sources is hydroelectric power. When you look at all the environmental impacts of dams, etc., they seem to be a lot less devastating than those effects due to the use of coal and oil for producing energy. Some of the environmental impacts include major flooding due to the gigantic reservoirs that are formed by dams, which in turn makes certain areas of useful land worthless (Baird). Another impact is that the flow and quality of the water may be affected in ways that the dissolved oxygen content of the water will decrease, but this problem can be minimized with proper flow control (US Dept. of Energy). On the other hand, hydroelectric plants do not release any emissions such as carbon dioxide or sulfur dioxide, both of which increase to global warming and climate change. This is a tremendous advantage over fossil fuel use. Also, there isn't any need to worry about nuclear disasters like there is with the use of nuclear energy.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
There are many benefits of using solar water heaters. Sunlight is free and environmentally friendly and this planet has so much to use(“Getting better acquainted”). The sun’s energy is renewable, suns energy is all over the world (“Getting better acquainted”). Solar energy has many uses, and it can be stored and used. “Solar energy can be used in many ways to provide heat, lighting, mechanical power, and electricity” (“Getting Better Acquainted”). New steps are being made in solar technology to save resources. America will save so much money and many barrels of oil by switching to solar power, “Skyrocketing fuel prices and tax credit of nearly 30% established in the energy policy act of 2005”(“Tapping into the sun”). The solar water system won’t cost much only “$3000 to $6000” (“Tapping into the sun”) so it will be affordable. “The technology can cut the average family’s costs to heat water by 20 to 40 percent (as much as 90% in some southwestern regions)”(“Tapping into the sun”).
