Renewable Energy Wind Farms - Essay Example With the limited nature of non-renewable resources, alternate renewable energy needs to be harnessed in order to fill the energy gap made as these non-renewable resources are depleted. Renewable energy sources include geothermal, biofuel, wind, hydroelectric, wood, solar thermal as well as and photovoltaic, and biomass sources. Renewable energy production across America varies state by state (Vaseashta et al., 2005). The intent of this exploration paper is to discuss why renewable wind energy is safer, cheaper, and cleaner than cleaner than fossil fuels. In addition, renewable energy production in replacing depleting nonrenewable resources can increase energy independence (at state as well as national level) and reduce risks of climate change associated with energy pollution of fossil fuels. Thanks to advances in technology, wind is becoming the fastest growing energy resource globally. Wind power is environmentally safe and does not produce atmospheric emissions or greenhouse gases (Hau, 2012). The main salient description of wind technology is that it is renewable, free, and can be efficiently captured. Renewable energy is important and meets population needs. This refers to job creation, economic demands, and energy security (Quaschning, 2005). Regarding cost deployment, a few issues have to be taken into consideration, the cost of renewable energy, the capacity of renewable energy and lastly the impact of renewable energy. It is argued that alternative energy is not cheap. When it comes to wind energy, the renewable resources are usually located in remote areas, and it is expensive to build power lines to the various cities. The usage of renewable sources is limited in that they are not always available, for instance, solar power is reduced on cloudy days, calm days reduce wind power and drought reduces water availability for hydropower.

The use of behaviourism theories on a social work case study Essay

The use of behaviourism theories on a social work case study - Essay Example This research will begin with the statement that the beginnings of social work are focused on the principle of providing aid to the people. There is minimal change in this perception, but it has shifted from the individual reformation to collective views. However, the central purpose remains to be the responsibility of helping the people, whether individually or collectively as one society. The vitality of social work practice has been never more emphasized with the prevalence of change and threats on each and every member of society. The most common concern of this discipline is the alterations of relationships and social institutions such as the family, which greatly affects the children. In response, theorists, psychologists, and social workers continue the study of human behavior and cognition to formulate methods and theories as a foundation for alleviating the effectiveness of social work. The use of the assumptions of behaviourism to empiricism is useful in examining the resul ts of the intervention. This demonstrates that social work practices grounded in this theory help provide better social work measures for both service provider and users. The case for this study is in Case Study No. 2 involving Gemma the 15-year-old daughter of Kitty and Tony and the sister of the nine-year-old Jake. Gemma is from a broken family with an absentee father, who left them after the discovery of Kitty’s extramarital activities with another woman. Gemma was once a promising child with good academic records.
