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!”
Humans need water. In a world that is overpopulated, we use a lot of water and other natural resources. Currently, in our world, clean water is getting scarce. Recently, for example, Flint, Michigan, had a water crisis. In early 2016, the water was discovered to be tainted with lead and other toxins. Long before that, the Michigan Department of Health and Human Services, and Governor Rick Snyder along with his council, knew about the lead, but to save money for the city of Flint in early 2014 Snyder had changed the city’s water source to the Flint River which had corroded pipes, causing people of all ages to be sick from the high amounts of lead
It’s no mystery that having clean water is a fundamental element to living in a prosperous society and one of the few things essential for human survival. Water not only sustains our health, but is required in making everything from electronics to clothes. Clean water may seem as ordinary as putting on your shoes, but it’s a daily party of our life that’s being threatened.
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.
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
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
Fossil fuels are known as non-renewable resources; the amount in the Earth is limited. On the other hand, renewable sources of energy, like solar and wind, are those that will not be depleted despite their continued use. However, solar energy is difficult to harness and wind energy is not very efficient. The clear choice of renewable energy is water. The Earth has plenty of water to use for power. After all, it is because of its great quantity of water that Earth is nicknamed the “blue planet.” Hydropower is entirely renewable because it is driven by the natural Water Cycle. Lakes and rivers that are used for hydropower will not simply run out because they are constantly being refilled by rainwater. In addition to being renewable, hydropower is superior to other energy sources because it is completely clean of carbon emissions. Once fully functional, dams power themselves and give off no excess gases. Power plants burn coal and pour unthinkable amounts of greenhouse gases into air. Hydroelectric power is a clean, renewable source of
Before delving in to what is actually wrong with seawater desalination plants, it is important to establish that there are plenty of alternatives available. One of the best alternatives is to adopt more efficient practices, such as conservation of water, and recycling storm water and grey water (from washing machines and bathrooms...
People don’t appreciated the many advantages that comes with having clean potable water to use, taking it for granted. A lot of clean useful water is wasted by humans all the time that people don’t care about saving water because they have easy access to it. Clean and safe drinkable water resources are getting scarce as the population grows. The world is facing many problems, but the most important needed to survive, is water. Water is getting low in many countries, therefore habitants are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages; meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands. Water shortage affects the agricultural sector, so as a consequence the price for production
Clean water is needed for good human and animal health, but as DoSomething.org states, over 1 billion people worldwide don’t have a means of getting clean drinking water, an...
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…”).
Having clean water to drink means that water must have microbial, chemical and physical characteristics that meet WHO guidelines or national standards on drinking water quality. Around 780 million people in the world don’t have access to clean drinking water (Millions Lack Safe Water). More than 3.4 million people die each year from water, sanitation, and hygiene-related causes. Nearly all deaths, 99 percent, occur in developing countries. Around the world, diseases in unclean water kill about 1,400 children every day (Clean Drinking Water). There are many organizations that raise money in order to help develop ways or create ways for people to obtain clean drinking water. However, many people are unaware that this is even a problem in other countries because we take clean water for granted.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
Although renewable energy can be expensive to build, it has less environmental damages 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. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night. Solar power does not pollute so much the environment. However, it has high maintenance cost, and it takes a large land space. Secondly, 15% of World electricity comes from wind. In order to have wind energy, it is important to have turbines to get the wind in order to produce electricity. Tall turbines produce more energy. The drawbacks of wind power are that it requires steady wind and its installations may interfere with TVs, cellphones, and other electrical devices. However, it is quickly built and there is no pollution nor noise produced. Third of all, the water falls in the dam can also generate electricity. For instance, 19% of world electricity comes from water. Regardless of the fact that hydroelectric power has low maintenance costs and does not pollute the environment, it can cause earthquakes, and destroy wild rivers. Only 0.3% of world energy
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...
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.
