Energy Resources Essay Example for Free

Energy Resources Essay Trade – offs for the energy resources Large scale hydroelectric power This taps the abundant energy resource presented to humanity by Nature in the form of water streams flowing under potential energy gradient presented by natural topography. This energy resource is practically free, practically renewable and exploiting this form of energy hurts the environs to the minimal extent. We can term it as green energy. This form of energy is very advantageous of economic development in remote and hilly terrain, where it is not easy to transport other forms of energy. This has disadvantages and limitations too. Construction of large dam required for large hydroelectric power in many cases leads to rehabilitation of a large population. A large dam (water mass) may lead to unduly high pressure on the tectonic plates and cause earth quakes with disastrous consequences. Besides, such plants have to be constructed in remote and hilly terrains, which is not an easy task in itself. Operation of the plant is made difficult by the silt that comes with the flowing water during rainy season. Passive solar power This converts solar energy into useful form of energy say heat which can be utilized for room heating, water heating etc. This is renewable or non exhaustive form of energy. This is highly eco friendly or green form of energy. This is distributed form of energy in the sense that this is consumed where it is produced, therefore, issues pertaining to energy transportation is not at all there. The features for exploiting can be designed in a building during construction or even retrofitted afterwards. What we get is heat only, which is not very useful form of energy. This is highly localized and can not be transported. This is not useful during night. It is not so easy to incorporate features for exploiting this form of energy in an existing building. This is not at all useful for those regions devoid of ample sunlight. Active solar power This converts solar energy into electrical energy by using photovoltaic cells. This is also renewable or non – exhaustive form of energy. This is green or eco friendly form of energy. This can be stored using batteries. This is also highly distributed form of energy as an active solar panel can be made of each household. This is working even when sun is not there i.e. during night or cloudy hours as the electrical energy can be stored in batteries. The disadvantages are very low conversion efficiency of solar energy into electrical energy. Small scale of solar power plants; large scale plants are yet become a reality and therefore, limited applications. Besides, toxic materials are required for construction of photovoltaic cells required for active solar power. Wind Power This converts energy of naturally flowing air current or wind into electricity. This is also renewable or non – exhaustive form of energy. This is green or eco friendly as it causes no harm to nature. This is available on large and industrial as well as small domestic scales. This can be very useful for development of regions devoid of other energy resources. This energy resource is not easily predictable or controllable. This is prone to seasonal variation as wind pattern follows a seasonal variation. The wind turbine is noisy.

Banning Cell Phones while Driving :: Law Legal Cellular Telephone

Cell phones have become a huge part of modern life.. Cell phones play a large role in our society from keeping track of the kids to calling for help in emergencies. As the popularity of cell phones increase, concerns over hazards and car accidents they cause has increased also. A law should be passed stating that all cell phone use be illegal while driving. Talking on a cell phone while trying to drive a car puts the driver, other drivers, and pedestrians in danger. The risk of a passenger, another driver, or a pedestrian being killed by a driver using a cell phone is 1.5 in a million per year. There are three dangers associated with driving and cell phone use. First, drivers must take their eyes off the road while dialing. Second, people can become so wrapped up in their conversations that their ability to concentrate on driving decreases. Lastly, people are constantly reaching for their cell phones to make or answer calls, making it impossible to keep both hands on the wheel. Adding to research that suggests that cell phone use while driving is hazardous, Progressive Insurance found that 46 percent of 837 drivers who used cell phones while driving swerved into another lane, 23 percent tailgated another vehicle, 18 percent almost hit another car, and 10 percent ran a red light. Of those surveyed, 90 percent admitted to using their phone while driving alone. Cell phone use while driving is basically the same as driving after drinking alcohol, both cause the driver to have poor speed maintenance, poor lane control, slow starts at signaled intersections, abrupt lane changes, sudden stops and cutting off other drivers. Driving while talking on a cell phone increases your risk of an accident from 34-300 percent same as driving drunk. Several states have attempted to pass laws to ban cell phone use while driving. Cab drivers in New York are not allowed to use cell phones while driving. On the other hand, those who appose banning cell phones while driving argue that when states issue drivers licenses, an individual motorist has been given the chance to be both responsible and capable of making decisions behind the wheel. Also, holding a conversation on a cell phone while driving is no more distracting than talking to a passenger. Lastly arguing that a driver should be able to chose whether or not to use a cell phone while driving and any attempts to legally prohibit this is taking away the personal rights of motorists.

Charity: High Schools

AP English Charity Many people donate to charity in their everyday lives, while others do it as an assignment. Individuals even give to charity just to receive money, gifts, or bonuses in return. Giving to charity portrays an act that certain people want to do for others, by the goodness of their hearts. However, then why do high schools ask their students who perform these tasks for a reward, such as extra credit and the ability to graduate? High schools that offer incentives for charitable acts become unethical since it takes away from the true meaning of giving. Teachers who offer students bonus points to those who bring in money, food, etc. don’t realize other people’s socioeconomic status. Although, by offering a reward will result in more students participating, those who live less fortunately may not obtain the food or clothing to donate. Families may be low on money; therefore enabling their children to donate to the cause and resulting in their child not receive bonus points since they need such items for themselves. High schools who offer incentives do not fairly give each student an equal opportunity. Donating for grades appears as unjust and irrational since not everyone may be able to afford it, while donating without expecting anything in return remains reasonable to everyone in society. At Wahlert Catholic High School we do not exchange donations for grades. It appears required of us to perform acts of giving to those of the community who reach out in need of it, without anything in return and enabling us to graduate. We do, however, arrange collections to help those in need. For example, when Japan experienced a tsunami, the whole school came together and raised a great deal of money to send over and help out. We donated from our hearts since we didn’t get anything in return. We remain left with the satisfaction of helping those in dire need of it. Therefore, the ways of the high schools such as Wahlert Catholic, happen to exist as ethical and portrays the truth behind giving to others in need. At Mazzuchelli Catholic Middle School, we did the very opposite and exchanged money for the right to come out of dress code. Yes, by doing this a lot of students got to wear whatever they wanted and the school raised a good chunk of money to give to nearby charities. However, the students gave their (or their parents) money not by thinking about the charities, but the clothes they became capable of wearing. This defeats the purpose of giving and carrying out the true Christian ways. Schools, such as Mazzuchelli, mean well by giving the opportunity to its children to do something new, in this case, no uniforms for the day. However, they should teach the kids the real reason to donated money, without the incentives they may receive. As Catholics, we should act in the way Jesus would and for the right purpose. We often ask ourselves, â€Å"What would Jesus do? † and wonder if giving to charity for a grade exists as the right thing? High schools need to encourage students to go out of their ways for others. Those who give to charity carry out their Christian morals by following in Jesus’ footsteps and doing what he would want his followers to do. On the other hand, by gaining extra credit or carrying through with charitable acts just to graduate exposes the wrong message. High schools that pursue these sorts of encouragements exist fair-minded, although others may argue it undermines the true value of charity. Students who give their time and possessions to charity act as true Christians and seem right minded. However, those who complete charitable deeds just to obtain objects in return portray immoral and wicked actions. High schools that offer its students the choice of donating for improving their grades usually mean well, but by doing this, it does not teach the kids the reason why they serve. High school students know to do what appears right and live out Jesus’ laws. Pursuing the act of donation affects many people and families, as well as influencing others to give. Therefore, carrying through the act of donation within high schools without any rewards reveals individuals as altruistic and leaves them with the knowledge of the true meaning of giving.

Stress And The Lgbt Teenager - 1738 Words

Stress and the LGBT Teenager Stressful teens are everywhere, existing in every middle and high school, hoping to get through the day. The amount of homework, after-school activities and social scene can put a lot of demands on a teen, especially a teenage girl. But, if you are a lesbian teenage adolescent, everything gets even more difficult and can lead to problems including stress, anxiety, depression and even suicide. The teen years represent a time when children begin to discover who they are. They acknowledge their social, personal, and sexual identities. In many cases, a student will not seek help, suffering in silence and feel more pressure. Many gay youths feel guilty about their sexuality and painfully different from their peers; they worry about the response from their families, friends, and teachers. Some teens have to go to school in a hostile environment and some encounter shame, social isolation and even bullying and cyber bullying on a routine basis. If a teen is feeling rejected or not supported by her family, she is far more likely to have these conditions. This does not mean, however, that LGBT identity itself is the cause of these challenges.
