The paper "Water-Energy IEEE Works Evaluations" is an excellent example of an annotated bibliography on environmental studies. EVALUATION OF “ THE FUTURE OF HYDROPOWER” This report analyses the IEEE Spectrum article, “ The Future of Hydropower. ” Hydropower, as the name suggests, is energy generated from flowing water. Flowing water is used as the force by which turbines are rotated at a high speed to a level where electrical energy is generated. The above-named article does not mainly dwell on describing how this energy is generated, but its main focus is on the prediction of the future of this form of energy.
Basically, the questions this article seeks to answer include questions such as, “ how long will this form of energy continue being available? ” or “ how are we sure of the availability of hydropower in the future? ” or “ if hydropower will still be available in the future, will the quantity be more or less” and, finally, “ how will the countries that mainly depend on this form of energy hack it in the future? ” The author talks of the difficulty in determining or predicting the flow of rivers because of the unpredictable and drastic changes in the climate.
According to the author, it subsequently becomes difficult to design dams that are in accordance with the flow of water. To support her evidence, Anne-Marie goes ahead to give statistics from an Australian case study of the Murray River which is either expected to be drier by 34% in the next twenty years or larger by 11%. The range here is therefore too large for corrective measures to be taken ahead of time. The use of hydropower can be traced back to 1882, where people used to generate hydropower for use in their grain mills among other uses (Draper 32).
As the demand for electricity grew, the need for bigger hydropower projects arose, and large dams were built to enable mass production of electricity. However, with time, the environmental impacts of generating power from water have been felt and understood. In as much as hydropower is non-polluting to the environment as compared to other sources of electricity production, it has some negative impacts on the environment (Draper 32). First and foremost, vast areas of forests have to be cut down to ensure adequate space for dam construction.
Dams usually directly affect the flow of a river, making the river sources drained of too much water. This is not to mention the fact that aquatic life is also affected when such flow is affected. Therefore, this gives the more reason why hydropower cannot be fully relied on for the future of a lighted world (Smith 130). Anne-Marie Corley, the author of this IEEE article, writes a clear thesis statement, which is “ figuring out how much hydropower there will be in the future… … ..is becoming more difficult. ” Also, the position taken by Anne-Marie in the argument was clearly seen and easily understood, not forgetting to mention the fact that substantial evidence was given to support the author’ s argument. EVALUATION OF “ EIGHT TECHNOLOGIES FOR DRINKABLE SEA WATER” This report analyzes the IEEE Spectrum article, “ Eight Technologies for Drinkable Seawater, ” which is written by Sally Adee.
Her main assumption, which is also the thesis statement, states that “ desalination of seawater is energy-inefficient, but emerging technologies will help. ” The eight technologies include thermal desalination, reverse osmosis, capacitive deionization, hydrodynamic spinning, and the use of alternative and better membranes, forward osmosis, osmotic power, and microbial fuel cells.
