Audience Analysis - Essay Example Actually, according to the American Red Cross young people constitute of about 20% of the nation’s blood donation (2014, para. 2). This implies that it is the role of all people to regularly donate blood in a bid to improve the health sector of our country. Every once in while, everyone encounters situations that require blood. This may be personal or someone we know. This implies that blood donation may be viewed as an investment for future use either by our own selves or other people. There are cases where people donate blood for their own future use but it is also important to donate blood freely and leave it open for everyone’s use. Most emergencies needing blood are accident related. Evidence has it that most blood donations are made during times of disasters (Baum, 1997, p.568). However, since we do not have control over accidents and we do not know when they will happen, the only thing we can do is to prepare adequately for when they occur. Donating blood can be considered one of the most effective ways to prepare for accidents. In addition to helping other people, donating blood also has many benefits in our health. For instance, researchers argue that people who donate blood regularly have an extremely low chance of getting heart related complications such as heart attacks (Medical West, 2014, para. 3-6). This implies that donating blood can be advantageous to us not only in cases of accidents or other illnesses but also in our normal daily routines. Reduced chances of getting heart related diseases can be attributed to the fact that regularly donating blood reduces iron levels in the body system. This is important in preventing iron concentration in the arteries hence reducing chances of getting heart attacks. Heart conditions are most prevalent among the older people and therefore blood donation can help reduce the risks even to much older

Various Methods of Electricity Production Term Paper

Various Methods of Electricity Production - Term Paper Example The pattern of production remains the same for almost all the forms of electricity production. One of the major sources of electricity production which is not environmentally friendly is through coal power plants. (1) Solar and Wind power have low environmental impact, low cost involved and this can be a viable option in rural areas. Solar, hydro and nuclear power are the best options for industrial and rural areas. The start up costs is marginally higher than the traditional methods but the long term benefits are better. (2) The Earth’s resources are not depleted if electricity is produced from the sunlight as solar energy is a renewable source of energy. There are 2 ways of producing solar energy from the sun: photovoltaic and solar thermal technologies. (3) 30% of the photon energy that comes in contact with the AE resource is being converted into energy in a photovoltaic cell. Silicon will be formed with the help of poly crystalline and the photovoltaic cells. Chemical reactions release electrons when they get in contact with PV cell is in contact with the sunlight. The current produced by these cells are placed in a module which helps in producing huge quantity of power for residential houses and industries. This source of electricity production has higher manufacturing costs in producing solar energy but in the recent times, the construction of photovoltaic has been made cheaper. (3) Another traditional way of producing electricity is to use reflectors and concentrate the sunlight to heat gaseous hydrogen, helium, oil to produce pressurized steam which helps in rotating the turbine and producing electricity. Many residential houses have these central receiver systems with mirrors that reflect sunlight on a large place filled with the fluid which helps in producing energy. (3) Nelson (2001) emphasises that the organic compounds used in the solar cells can be made out of inorganic compounds which will
