Solar power is a form of electricity generated from the energy obtained from the sun. This conversion may occur indirectly through the concentrated solar power (CSP) concept or directly by use of photovoltaics (PV). Analysts indicate that the energy released by the sun to the earth exceeds the power consumed by human beings by 35,000 times (Armentrout and Patricia 50). Excess energy, in the form of solar radiation, is reflected back to the atmosphere. This shows the underutilized capacity of solar energy in attaining sustainable developments. The photovoltaic systems do not release greenhouse gases in the power generation process. Moreover, they can convert sunlight into electricity even in conditions of low solar energy. This proves that solar power can be available for use in domestic or commercial buildings even on cloudy days. In contrast, the indirect conversion of solar energy through CSP techniques involves the generation of heat energy and using the resultant steam to operate power generators (Hirschmann 36). Similar to the photovoltaics structure, this system does not have any environment-degrading emissions.
The high-energy intensity obtained from the sun is the main reason why solar power is considered reliable and useful in establishing and maintaining profitable commercial projects with the main aim of increasing the local and global economies (Mahaney 112). For instance, various scientific experts have proved that the sun is able to provide the world with enough power to run all domestic and commercial projects for a year by shining for one hour. This fact is the underlying principle behind the recent operations of the National Center for Photovoltaics (NCPV). This national agency seeks to use solar power to cater ...

...vestors should collaborate in increasing the production capacity of solar energy. This is because of its numerous benefits, which include cost effectiveness in the installation, generation, and maintenance, as well as its renewability. In addition, it is a reliable source of energy especially due to its availability in all seasons of the year in significant portions. With the advanced technologies in the modern world, the general population in different countries will benefit from this scientific discovery without incurring huge costs at the domestic and commercial platforms. Other subsections that should adopt solar power systems include academic institutions and government agencies. In addition to facilitating economic developments, the maximum utilization of solar energy will help in solving the problem of global warming since it does not utilize fossil fuels.
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.
The prime advantage of this approach to harnessing solar energy is that the process is simplified by combining energy gathering and storage into a single step. This process is robust, stable and cheap. One limitation of this process is, while this is useful for heating applications, production of electricity would require another step using thermoelectric devices or producing steam to run a generator.
The sun warms up the planet but people can also use that to warm up their own house. Not only does the sun help with heating but it can also help with other renewable energy sources. The sun is considered the most powerful energy source because it makes wind, is part of the water cycle by evaporating water, and it helps plants grow (West). Solar power uses the dark blue, tile looking machines known as photovoltaic devices that gather the energy and convert it into energy (Wieman). Since the sun does not always shine on the same spot, people need to choose the location of these devices wisely. When they have the device in the right position then they can start gathering power. Solar power collects solar energy from the sun, then “converts that into sugar and starches which then break down to create chemical energy” (Heinrichs, 12). This seems as a wonderful but not many people realize how...
The sun exists as one of the highest abundant sources of energy. Yet the world neglects to implement solar technology as a dependable resource. Daily, Americans make the switch to solar energy and cut dependency from local utilities. One of the greatest advantages of harvesting solar energy stands that the sun shines for long durations throughout the day and the sun rises every day; hence, reliability. Other natural renewable resources are available such as hydro, wind, geothermal, biomass and nuclear energy. Renewable energy is the key to improvising in the way we create energy while minimizing damage to the earth. Through thorough research science and engineering have created high tech technology that emits less Co2 by
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.
The drastically increasing prices of fossil fuel and gasoline are making it harder for us to afford it. The fossil fuel is a natural resource which is reducing the supply of our reserves every second. It is one of the main sources for spreading pollution and global warming which is affecting our health as well as our environment. Solar energy is a suitable replacement of fossil fuel in term of green environment, recyclable, affordability and long lasting. Although, there are still many issues with solar energy which needs to be solved, but its availability far exceeds any conceivable future energy demands. A number of benefits could be gained from solar energy which includes dishes that concentrate the sun rays to heat fluid which drives engine and produce power. The installation of solar energy panel is very convenient and it could be attached on the roof of the car and building or any surface which has direct access to sun light in order to generate cheap and affordable electricity.
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...

Solar Energy is an alternative electrical energy source. Its a renewable source, because of its abundant supply and limited environmental impact. Solar energy has the ability to power buildings, electronic devices, and spacecrafts through a specific process. The energy is harvested from the sun to made usable, thus it is a renewable form of energy. Solar energy is created by the use of solar panels, a collection of photovoltaic cells (solar cells, that mean light and electricity). The solar panels have a system in which, it collects the sun’s rays and converts it into energy (similar to the organic process of photosynthesis in plants), and sto...
Solar power is one of the renewable energy resources that was develops to replace the fossil fuel. It was one of the most convenient and clean energy resources that are available in the earth. The solar power operations involve the conversion of sun power to electric power with the use of photovoltaic cell. The whole process is clean and will not produce pollutant to environment. In 2011, the International Energy Agency encourages all countries to develop solar power technologies. They emphasis that the early development investment cost should not be cut down and the research should be shared among the countries as solar power technologies brings huge global long terms benefits toward mankind. Such an advantages include: increase the countries energy security as solar power is a free and inexhaustible resources that can be obtain from the sun, reduce the pollutant toward the environments, and decrease the energy dependent toward fossil fuels which will lower the price of fossil fuel. These energy resources are the mos...
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.
The sun shines upon Earth every day, yet no one thinks much of it. Solar power’s importance, though, is above what anyone could have ever imagined. There is active solar energy, which is when solar power is converted into light, heat, cause air-movement for ventilation or cooling, or store heat for future use. Less thought of, the other type of solar energy is passive energy, which most take for granted. Solar power provides life with heat, light, and now, electricity. Solar power also plays a role in 4 of the 5 areas of green technology: energy, green building, environmentally preferred purchasing, and green chemistry. All in all, solar power is quite a unique form of energy.
Solar energy is clean energy that does not affect our environment. Solar power utilizes the sun’s energy to produce electricity, unlike other sources of energy, which rely on continual mining for raw materials. Consequently, producing solar energy from the heat from the sun does not result into the annihilation of the ecosystem, compared to the extraction of fossil fuels (Bode, 2005). Therefore, with the use of solar energy, it will help keep the environment clean, thus help to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide. The use of solar energy will help save the worlds vegetation, and help prev...
