1. Introduction Solar energy provides a safer, more viable and sustainable alternative than current fossil fuel technology for the production of energy for large-scale consumption. Solar energy will be critically analysed, the analysis will include physics concepts behind solar energy, as well as benefits and issues. Why is solar power so needed in the world today? In recent times there has been more awareness of Global warming, an effect of continuous use of fossil fuels.
Due to the predictions of the depletion of oil in the near future, many countries start to depend on renewable energy sources. Since solar power is one of the best choices, many massive solar energy projects have been established. Whiticar et al. state some examples of enormous solar power projects. Firstly, the largest project is SEGS, located in Modjave Desert in U.S., which uses solar thermal technology to produce enough electricity for half-million people.
Federal funding is increasing to prevent any future energy crisis, which United States experienced three decade ago. Solar energy is capable to use as cheap non-renewable energy source to fulfill whole world’s energy demand. Solar power usages reduce earth pollution. Truly, sun power is best energy solution for future generations. References Jha, A. R. (2010).
We can look towards more nuclear power plants, whilst not exactly ‘green’ they produce no carbon emissions and massive amounts of power per year for the needs of the county. Though In recent history, nuclear plants have gained a bad reputation due to disasters such as Chernobyl. There have been technological advancements allowing nuclear plants to almost run themselves, requiring only a handful of workers to operate properly. The other option is the use of ‘green’ renewable solutions in the form of: Wind, solar, wave, geo-thermal and hydro-electric. These solutions whilst being very expensive to set up initially and have a larger carbon footprint during setup than nuclear plants they will, in the long run produce no carbon emissions, have a very small footprint on the landscape and eventually pay off their initial set up costs.
Solar power is a relatively untapped power source which could contribute to solving the energy crisis. Solar power plants can operate as long as the sun continues to give off light and heat, and it will continue to do so for billions of years. However, solar power plants cannot be the only power source, for they do not operate at peak efficiency at night or when the sun is obscured by dense cloud cover. Solar power accounted for only 0.064% of US energy consumption in 2003, while fossil fuels accounted for 85.973%. Also, solar power production in the United States has been decreasing since 1996 (see Figure 1) (Annual Energy Review, 2003).
Solar power has its advantages but most of the people the people think the solar panels are expensive disadvantages, but it’s actually an advantage. Solar power starts saving money from day one. Electricity is one of the key things we need to clean up and solar power is the way to do so. (Shanan 1-4) Solar energy is a visible form of alternative energy. Solar panels capture energy from the sun’s rays and convert it to electricity.
Unfortunately one of the biggest cons that face solar power is the argument that the shine does not shine in all places as much as others such as Alaska. Utilities have argued that the reliability on electricity could be at risk if not much solar power is produced in those areas with the lack of sunlight in areas depending on the time of the year. One of the benefits of solar power is that if
Or, with increasing complexity, it can turn the heat into electricity. Unfortunately, much of this technology is too expensive and complex to be practical in the United States on any large scale. However, solar photovoltaic cells are a far more promising technology. They provide a simple way of turning light directly into energy. This paper will examine how this technology works on a basic level while accessing the possible benefits and problems this technology has.
Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
Questions include how to reduce the costs of the component and the plant, how to increase the operating temperature further beyond 500*C, how to alleviate the plant performance, life, and reliability, as well as how to properly increase the plant’s production. One more important question that remains to be answered is how to successfully commercialize solar power in general. It is still a significantly new concept in comparison to fossil fuels and commercializing includes public awareness that solar power is definitely an energy that can be used without depleting the Earth’s resources.
