Assignment 1: Discussion—Renewable Resources Each Type Of Po

Assignment 1: Discussion—Renewable Resources Each type of proposed renewable energy has its benefits and drawbacks. For example, hydropower has the benefit of relatively consistent results; however, it remains controversial due to its impact on aquatic environments. For this assignment, select one renewable resource to examine its benefits and drawbacks. Using this module’s readings, the Argosy University online library resources, and the Internet, respond to the following: Describe the sources of this renewable resource. Explain how this renewable resource is harnessed for energy. Considering that it takes energy to make energy, identify the kind of energy needed to make electrical energy from this resource. State the average amount of energy this renewable source produces. For example, on average, how much energy does a single wind turbine produce in a year? Or, how much energy does a dam produce in a year? Or, how many wind turbines would be needed to produce the same amount of energy as the average dam? Compare and contrast the benefits and drawbacks of the renewable energy resource. Support your statements with scholarly references and appropriate examples. Write your initial response in a minimum of 350–400 words. Apply APA standards to citation of sources. By Saturday, August 9, 2014 , post your response to the appropriate Discussion Area. Through Wednesday, August 13, 2014 , review and comment on at least two peers’ responses. Address the following: Given the associated benefits and drawbacks, explain whether this particular renewable resource was best for your classmate’s community. How would this renewable energy resource replace the current energy resources in your classmate’s community? What are some reasons why this energy resource has not already been harnessed in your classmate’s community? If the renewable energy resource that your classmate described is used to replace the nonrenewable energy sources, who would benefit the most?

Renewable energy resources are critical components in transitioning toward sustainable and environmentally friendly energy systems. Among these, solar energy stands out due to its widespread availability and technological maturity. This discussion explores the sources, harnessing methods, energy production, benefits, and drawbacks of solar energy, providing a comprehensive overview of its role in modern energy landscapes.

Sources of Solar Energy:

Solar energy originates from the sun’s radiation, which reaches the Earth in vast amounts every day. This energy is generated through nuclear fusion reactions within the sun’s core, releasing photons that travel through space to reach our planet. On Earth's surface, solar energy is harnessed primarily through photovoltaic (PV) panels and solar thermal collectors. Photovoltaic panels convert sunlight directly into electricity using semiconducting materials such as silicon. Solar thermal collectors capture solar heat for use in heating applications or to generate electricity via steam turbines.

Harnessing Solar Energy:

The process of harnessing solar energy involves deploying solar panels in areas with maximal sunlight exposure. Photovoltaic cells undergo a process called the photovoltaic effect, where photons excite electrons in the semiconductor material, creating an electric current. Solar thermal systems use mirrors or lenses to concentrate sunlight to produce high-temperature heat, which can drive steam turbines connected to electricity generators. Recent technological advancements have increased efficiency and reduced costs, making solar energy increasingly viable on a large scale. Solar farms comprising hundreds or thousands of panels generate significant electricity, feeding it into the grid.

Energy Production and Efficiency:

On average, a standard residential solar panel system of about 5 kilowatts (kW) capacity can produce approximately 7,000 to 9,000 kilowatt-hours (kWh) annually, depending on geographic location and weather conditions (U.S. Department of Energy, 2020). Comparing this to large-scale solar farms, a 100-megawatt (MW) solar power plant might generate roughly 150,000 to 200,000 MWh annually (Khan et al., 2019). The efficiency of photovoltaic cells typically ranges between 15% and 22%, influencing the total energy output. For context, to replace a 500 MW coal power plant operating continuously, approximately 2,300 MW of solar capacity would be needed, considering capacity factors (Candelise et al., 2018).

Benefits and Drawbacks:

The advantages of solar energy include its abundance, renewable nature, and minimal environmental impact during operation. It reduces greenhouse gas emissions, decreases dependence on fossil fuels, and creates job opportunities in manufacturing and installation sectors (IRENA, 2021). However, drawbacks include intermittency due to weather and diurnal cycles, the need for energy storage solutions, and significant land use requirements for large solar farms (Boyle, 2018). Additionally, manufacturing and disposing of solar panels involve environmental considerations related to materials and recycling.

Conclusion:

Overall, solar energy offers significant environmental and economic benefits, though challenges remain regarding storage and land use. When integrated thoughtfully into energy systems, solar power can substantially reduce greenhouse gas emissions, promote energy independence, and foster sustainable development. Continued advancements in photovoltaic technology and energy storage are expected to mitigate current drawbacks, making solar a pivotal component of future renewable energy strategies.
