Water is considered the most abundant compound material on the planet, and is also essential for all living habitants. Two thirds of our world’s surface is made up of water and close to 70 percent of the earth is made up of human beings, thus there is a clear sight that water is the prime element which is responsible for life on earth. No matter the essence, water is a resource we cannot do without especially to maintain a certain quality of life. As a society we need to do everything that we can to sustain its quality and quantity in order to also sustain the life on earth for not only today, but tomorrow as well. Human beings have lost respect for water, which is evident in how we dump sewage, garbage and chemicals in our rivers and other water bodies, exploit the living bodies in the water even to the point of extinction. The International energy agency defines renewable energy as energy which comes from natural resources such as sunlight, wind, water and geothermal heat of which are all considered renewable (Pelman, 2014). People day in and day out find ways to answer the questions of “how do I fully insulate my house?” or “what energy options do I have to save money?”, and then also comes the “what energy options are good for the environment?” There are many things that can be done to tackle most of these questions, but then none of them come close to the ones offered by Hydroelectric Energy. It’s always been documented that there is an increasing trend of an average of about 6.5% per year in consumer bills over the last thirty years in the United States. Global demand is expected to increase by as much as 59% in the next 15 years. With such a demand, there is clearly supposed to be an expected rise in energy bills (Wate... ... middle of paper ... ...s or Aristotle in explaining the essence of a thing and its value to humanity (Martinez-Gil, 2001). The essence of nature is most especially defined by properties that define it such as its molecular structure. All through history and in present times, the conditions of society have permitted the existence of very rich “water cultures”, and what has been gravely considered as a necessary resource and in certain instances a spiritual wellbeing. The construction of hydraulic public works and the conversion of dry lands into irrigated ones has always been the means for social and economic developments especially in the area of urban migration. Powerful technology and reasoned funding have allowed of the construction of varying infrastructures such as reservoirs and out-of-basin diversions to deal with the migration as well as any threats of water shortage or pollution.
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
We often hear the saying that water is the source of life so how can mankind waste this precious source that God has given us. A fine example was mentioned in the film about India’s new green agricultural system where 30 times more water is been use than the actual amount required. It is really hard to see how these farmers are spitefully wasting water when it is really needed in the neighboring communities. This goes to show that people only do things to benefit themselves not considering the needs of other people. Not only is water being wasted in developing countries but there is also water wastage in developed countries we often take our water sources for granted here in the US such as not turning off the pipes when brushing our teeth or washing our hands and the list goes on. Water conservation is the key to saving our planet because soon it will become extinct to us human beings.
Many differing opinions exist on what needs to be done about our current status of conserving energy and conserving our environment. With increased gas prices and energy costs, consumers are more aware of what benefits are available and the methods of obtaining them. The introduction of hydropower has been a major step for some, while a stumbling back for others. Advocates for hydropower have provided much information about the many benefits that we reap from using hydroelectric dams. Environmental activists denounce the many negatives that are created by the numerous dams located throughout the United States as well as other countries. Both sides present valid arguments and need to be addressed in order to fully understand the complex social, biological, political, and economic pros and cons.
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...
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.) that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone. I believe the only way the United States and the world will see a large-scale transition to renewable energy sources is through education. Right now, it seems as though only a few pockets of people throughout the world are aware of the positive benefits of renewable energy sources. Not only is it better and cleaner for our environment, but the industry of renewable energy could also
Below I will list a table with the pros and cons of renewable energy as it is the biggest solution to the huge issue of overusing electricity. Next I will be discussing what we a society can do to further improve this situation and my main point lies within hydropower. Hydropower is the renewable energy contained in flowing water. Electricity is generated using hydropower known as hydroelectricity and is generally considered to be reliable.20% of the world’s electricity consumption in 2006 was generated with hydroelectricity (generating electricity from hydropower), the most used renewable energy source in the world. We all know that hydroelectricity is both renewable and green, but what are the other advantages this technology offer? Are there any disadvantages? Look below at figure 2 to see the pros and cons of hydropower. There are many changes to be made whether it be in a single home or as a community, we may face obstacles but that is what it is all about, we have the resource to use all we need to do is use them in the write up above I've listed problems that lie within my home as well as solutions we have done to fix the mistakes we made. I hope you enjoyed and learned a bit about resources and how to use them with all the effort
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
Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well-populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options, increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions. a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy Use”). Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants.
Clean Water: “An under-appreciated liquid to Survive” Water is pure and transparent liquid that is vital for all humans, plants and animals on the planet. In the United States, people have access to clean drinking water and clean sanitation systems, not like in other parts of the world where clean, safe drinking water is getting scarce. A lot of people don’t have access to it, and many regions are suffering severe drought. Yet, when humans take it for granted, they don’t appreciate that a reliable, clean supply of water is essential to human health, economy and agricultural prosperity. Having clean and safe potable water is a right, and not a privilege.
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…”).
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.
Water is on of the most precious natural resources that exist on our planet. “It is delivered from the atmosphere in the form of rain, snow, hail, fog, and condensation and returns to the atmosphere by evaporation and transpiration” (Hannigan 1969). Although many of us love activities that have to do with water, we disregard it and pollute out rivers, lakes and oceans. Slowly but surely we are going to harm out planet till no return. Protecting and conserving nature will secure a better future. 71% of earth is covered with oceans. Sounds like a lot right? Imagine ...
Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical 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.
