1. Introduction Due to the important of energy in the development of economic and prosperity of a country and with the growth of worldwide population and industrialization, the demand of energy has been dramatically increasing. However, the use fossil fuel to produce energy has many negative effects on the environment such as increasing the world’s carbon dioxide and depletion of fossil fuel resources which are serious issues these days. As the result, renewable energy, namely wind, solar, biomass and geothermal energy, has been encouraged by many countries as its sustainable use and not contributing to the world’s carbon dioxide emissions. Specifically, as the sun is the most abundant, reliable and pollution-free power in the world, solar power is becoming an alternative energy and has an immense potential to meet the future world’s energy demands. However, solar power depends on many factors such as the sunshine, weather and sun power systems which are potentially prevent it becoming a more utilized energy resource. The purpose of this report is to investigate the problems with using solar power as an alternative energy and suggest possible solutions to these. Firstly, this report describes two important problems with solar power, namely the expensive cost and low efficiency. Secondly, the report suggest that the support of government is a possible solution to the expensive cost and low efficiency can be solved by the development of technology in solar power system. Finally, this report concludes by proposing recommendations which governments and scientists can adopt in order to lessen these problems and make solar power become a reliable and widely utilized energy source. 2.

Secondly, the low efficiency may improve by the innovation of technology which are the technical and design improvement on photovoltaic systems, storage systems and concentrated solar power systems. The above findings demonstrate the need to mitigate problems with using solar power not only because it is an alternative energy but also because solar power has huge long-term benefits as an endless, sustainable and clean future energy. Therefore, this report recommends that government need more promotion in future to support and boost the research and development of solar energy system which also need the collaboration of the scientist on technical issues. A further recommendation is public encourage in order to widely utilize solar energy in the world.
With the growing cost of fuel for cars and the rolling blackouts of last summer, the need for an alternative, cost-effective, environment friendly energy source is escalating. Many possible solutions have been presented, such as nuclear power, wind power, and hydrogen fuel cells; prevalent among these is solar power.
One of the issues that has a significant influence on sustainable economic and social development is energy. The utilization of energy results in climate change owing to its impact on environment by greenhouse gas emissions. This is resulted from the convention of using oil, gas, and coal that emit CO2, NOx and other poisoning substances into the air. The national strategy of China is to reduce this pollution by replacing fossil fuels with alternative energy such as wind, nuclear, geothermal, hydropower or solar energy. (Zhen 2008). Qian and Ling state that Northwest China is an ideal place to develop solar energy, the energy used by absorption of sun radiation, because there is a very wide access to sun heating, which is about 2000 hours a year. (Qian and Ling 1998). However, since there is a very little support from science, government and market, that fact causes the main difficulties to popularize this energy. Despite high prices some of the solar energy technologies have been already installed, and after several years’ costs decreasing the economic growth enables China to achieve the highest level of solar energy development in the world in 10 years.(Bullis 2010, 53). Although there are many useful and perspective features of applying solar energy technologies, the purpose of this study is to analyze advantages and disadvantages of the impact of solar energy and using these technologies on environment and economy in China. Firstly, there will be discussed the role of solar energy in environmental, socio-economical, and political issues. Then several kinds of solar energy technologies and their application will be demonstrated and analyzed. Finally, the answer for the question whether China should spread the development of the...
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Most of the people in our modern day society are beginning to realize that fossil fuels are becoming more rare and are damage our planet, this creates the need for a more sustainable form of energy. Solar energy is one of them and is becoming more and more important and will hopefully soon replace this obsolete technology.
Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
Solar energy products can range from solar panels to cell phone charges, and everything in between. Solar energy is becoming a popular way to fuel homes throughout the United States. All over the country, people are covering their rooftops with solar panels, heating their pools with solar energy, and even turn on the lights in their homes with solar energy. Solar power is quickly becoming America’s most popular form o...
As the increase in the consumption of energy gradually increases per year, the government needs to take measures in opting to renewable energy sources, preferably solar energy because of its decreasing price, versatility, and its abundant main source of energy.
With the world’s natural resources depleting rapidly, humans must find a way to compensate. This society has milked oil, coal, gasoline, lead, uranium, and many other of these reservoirs in our Earth for hundreds of years and much has been done. Asphalt was used for our roads and highways, coal was originally used for heat before there was oil, and even water was used as a form of electricity on many rural farms. Luckily, more companies around the world are waking up to the fact that these resources will not be around forever, and that in the near future, other forms of energy will take heed. Solar energy, or energy powered by the sun, is one of the most promising. Since the sun’s rays create so much for the wildlife that surrounds us, why can’t it do the same for people? It can, and as many industries are finding out, will be around long after the other resources are gone.
Some say that solar panels can be very costly. Even though the sun is a free resource the cost to building it is expensive. Solar power is only effective during daytime, but the demand for the energy, it is continuous...
India is blessed with ample solar energy available which in turn can produce 5000 trillion KWS power by having average 300 sunny days per year and solar insolation of 4-7 kWh per Sq. m per day. Thus efficient trapping of solar energy could provide an alternative to fossil fuel dependent energy production. With increase in demand for power, now private sector has also started to invest in solar power due to better technological maturity and cost competitiveness. Technology for transforming solar radiation energy into both heat and electricity can harness solar energy effectively and have huge potential in scaling up power production. As there is positive correlation between energy requirement and GDP of the country, solar energy can address energy deficit in demand by both Off-Grid power supply ...
At the bottom of water is plant matter. That is what coal starts off as. It is covered in sediments and eventually goes through metamorphosis. After metamorphosis, it eventually becomes coal, which is one of the three most important resources on Earth. Another resource is solar energy, which is now being widely used in a variety of ways. Panels and sun light are what is used to collect this type of energy efficiently. The third type of energy resource is water. This type of energy can be conserved when a plan is implemented. A good plan can save not only water, but money too. (Science Kids, 2013)
Solar energy is one of the renewable energy sources that are highly sought after because of its applications and also as of the cleanest forms of energy. Solar energy applications are constantly increasing in the last few years, and they are considered perhaps the most promising that can significantly contribute to the total electricity generation. Solar Photovoltaic cells (PV) and the concentrated solar power (CSP) technology are the two main technologies out there when it comes to solar energy applications. These two are discussed below.
...VII show that there is a need for solar applications in Singapore for a cleaner environment. With the strategic location along the sun belt with high solar irradiation makes Singapore a suitable place for solar PV systems deployment. Applying solar systems in Singapore enables the production of electricity without depending on fossil fuel combustions, hence, the ability to sustain the increasing electricity demands without having to worry about sudden increase in fuel prices. Lastly, with the support from government, more private sectors such as industries will be able to engage in renewable energy projects in buildings that will turn the energy consumers into energy generators.
Solar energy is that energy which is gets by the radiation of the sun. Solar energy is present on the earth continuously and in abundant manner. Solar energy is freely available. It doesn’t produce any gases that mean it is pollution free. It is affordable in cost. It has low maintenance cost. Only problem with solar system it cannot produce energy in bad weather condition. But it has greater efficiency than other energy sources. It only need initial investment. It has long life span and has lower emission. The sun is the original source of almost all the energy used on earth. The earth receives a stock ring amount of energy from the sun, as much energy falls
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. 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.
