Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different

Many job opportunities today show that there is the considerable need to acknowledge the newness in this technology (Wilber, 2012). This is because it is not in any way a permanent solution of oil importation but it is an alternative energy source, more like a bridge source, that gives time to develop better technologies.

Our energy use has dramatically improved our lives , but this energy is derived mostly from fossil fuels and has resulted in environmental change , and depletion of fossil fuels (Shahriar 181 ). This leads to continuing military conflict . This resulted in developing and using alternate resources for the increasing energy demand.

According to article, “In a high-quality program, there is a focus on developing healthy and strong human relationships (p. 40). The program takes place in Condor Elementary School. They used the cafeteria to give them a snack, and make Woven Baskets for children in Protective Services. They had plenty of space to do their project, there were many tables and benches for them to openly do their work, as well as move around. They had a 12-child/2-teacher ratio, which facilitates the supervision of the children. They provided all the material (had plenty of them). They also had board games, plenty of art supplies, and books. In addition, they were provided with outdoor physical activities.

According to David Sedlak, we have made large progress in seawater desalination for the past 2 decades. The largest seawater desalination plant in the Western Hemisphere that is built north of San Diego uses half of the energy use than Santa Barbara 25 years ago. One reason why Sea Water is a good way to save more groundwater because we do not have a lot of water, but lots of oil. Also seawater desalination is not always good, there is a negative side. It is energy intensive; that means that it will cause a lot more climate change, but that is the only negative thing David Sadlak had mentioned about seawater desalination; but so far the new seawater desalination plant uses half the energy it used to. This would help California because it would lower the amount of water that is pumped from the ground, therefore, seawater desalination is a possible solution for conserving more

Today, desalination is a common process that's used in seaside cities and towns worldwide. There are more than 15,000 desalination plants around the world providing freshwater from salt and brackish water alike (Planet Green 2011). This number continues to grow as researchers work to improve the process, both in terms of cost effectiveness and energy efficiency (DSE 2011). But countries such as Australia, Israel and even the United States are continually adding desalination plants of various sorts into their water-management portfolios. The facilities are common in North Africa and the Mideast, where freshwater is scarce (Chandler 2008).

America has always been the leader in science and innovation. It has the best universities and research labs. Many successful entrepreneurs have been raised from this nation. Thus, it has to take benefit from these significant comparative advantages to generate new pools of jobs for its people. As I mentioned in the introduction, we should let history to be our guide to plan for future. Toward the end of the last century Japan was getting ahead of U.S. in most aspects of technology and industry including in automotive and home appliance industries. Most economists at that time predicted that in near future Japan’s economy would pass America’s economy, but this did not happen. Thanks to Americans innovation and ingenuity, the Internet was born in U.S.A which became the prevalent technology of the future and revived the U.S economy. Today, America is in need of such innovations. The world is in shortage of energy and the oil and natural gas resources are running out. Therefore, the price of energy will definitely increase. I believe that the capability of storing and using alternative and renewable energies in day to day life can be the next big discovery that is very likely to revitalize the economy and to create a new generation of jobs. Thus, emphasizing on research on alternative energies can be a feasible strategy to maintain a healthy workforce in the mist of outsourcing.

Thank you for allowing me to having the honor to write this to you. However, I think that as Americans, we need some new ideas to create energy from renewable resources. Here in America, we use an excessive amount of fossil fuels, such as coal, oil, and natural gas. These resources will not always be available to us, therefore, we should come up alternatives that will last longer, be replenished faster, and will be fairly cheap. We need to solve the problem as soon as we can.

Our rivers are running dry faster than we expected. As we look for a solution to the scarcity of water, we are relying on the most abundant resource that is available on Earth — the ocean. To make the salty sea waters usable, scientists have developed desalination plants; a method that uses reverse osmosis and is already being implemented in places like California. However, as with any possible solution, the desalination process has its downfalls. Critics of the desalination project argue that it is more expensive than other potential methods and that the amount of energy required will only aid climate change. Those who support this method would argue that although it is currently expensive, new, cheaper filters will be developed in the

The process of desalination has been around for a very long time Greek sailors use to evaporate the salt water capturing the vapors and drinking the condensation of the newly filtered water. This creates new

The title of my science project is "Half Baked". My problem was some of the cookie sheets take longer to cook rather than the others. My hypothesis is that I thought that the insulated aluminium cookie sheet would be the most effective in cooking the cookies. My procedure was first, I gathered the materials that I was going to use, next I preheated the oven, Then I observed the cookies and recorded the results and analyed the data and came to a conclusion. I used different types of cookie sheets and set the cookies on for 12 minutes each and recorded how long each cookie took to fully cook. In conclusion the insulated cookie sheet was the most effective and took a shorter time

One of the most important aspects of the development of engineering is the harnessing of different energy sources and the world, today, is highly reliant upon this (Narendra Singh Rathore, 2007). This report will endeavour to

The International Energy Agency estimates that by the year 2003 forty percent of the world's energy production will be from sources other than fossil fuels or nuclear power. Nevertheless, the need for

These two factors, have impeded the mass construction of desalination plants worldwide. Technology in renewable energy and reducing the cost of desalination needed to play catch up before global initiatives were developed to Desalination plants run on energy from fossil fuels is too expensive and not sustainable. Currently, existing desalination plants use equivalent amounts of fossil fuels to produce freshwater as plants that produce freshwater from ground and surface water. (Gnaneswar Gude) In order for desalination to be a solution to global freshwater scarcity it must be produced using less fossil fuels than currently required in freshwater plants. Ideally, desalination plants would be fueled by renewable energy such as solar and wind
