Solar Power Of Solar Energy Essay

Solar energy is a renewable energy source meaning that the energy is generated by the sun. The way that solar produces energy is by the sun's rays that reach earth and converts into heat and electricity. Its transported by photovoltaic ( pv devices ) and solar thermal electric power plants. Examples of this energy source is : solar powered window blinds, bulbs, refrigerators, radios, calculators,

Stretching across ten countries and spanning over four thousand miles, the Nile River became the heart of Egyptian civilization. The lower (northern) Nile overflowed its banks several months out of the year before the creation of the Aswan High Dam in 1970. When the floodwaters receded, they left a new layer of rich silt behind, making the surrounding valley and delta a fertile and desirable habitat. As early as 8000 BCE, the people who inhabited the valley of the world’s longest river became relatively sedentary and in 5000 BCE they adopted the agricultural village life commonly associated with Neolithic culture. Throughout the Predynastic period, the North African climate was immensely dry. In order to combat this problem, many villages formed alliances that worked to control the river’s flow. Over time, these small federations of villages conquered and absorbed other weaker ones. As communities grew into chiefdoms, they began to advance rapidly toward refined civilization shortly after 3600 BCE.

Imagine you are a troubled kid that grew up in a gang-controlled neighborhood. You live day to day not knowing if today is you or your family‘s last day. Now imagine someone telling you that they can give your family money to help them get out of the hood and into a safe place. You have a scholarship to a major university and if you work hard you will become pro and make millions of dollars a year. But you can’t bear to see your family suffer any longer so you take the bit of money and use it to get your family to be safe. Now that same university is filing sanctions against you and the person that gave you the money. They are dropping your scholarship and now no other college in the country will take you.

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

The sun is a massive burning ball of hydrogen that outputs gigantic quantities of energy every second. Sunlight is an excellent energy source and the future of using solar power is very exciting. The Sun's energy can be used to heat and cool buildings, generate electricity, operate communication, and GPS systems and even power solar cars. The sun’s energy is clean and solar panels used to harness the energy are low maintenance.

With global warming and climate change, our mother earth’s deteriorating health has become a serious problem and is affecting the lives of all species, including human beings, that depend on its plentiful resources to survive. Oil, or petroleum, a nonrenewable energy source, is now running out, being also one of the major obstacles we face nowadays—the extraction and burning of oil done by human beings have been contaminating the environment, water sources, and the atmosphere. Rising prices of oil will also become a problem in the future if we continue to neglect the danger (Reese, Richard. “Oil and The Future.” Eco-Action, Dead Trees EF, 1997, www.eco-action.org/dt/oilfut.html. Accessed 2017). Thus, it is very

Solar collectors technology is used in many parts of the world including the U.S., China, India, and the Middle East. Systems have been adopted for a wide range of use patterns and climate conditions. However, most existing systems are geared toward wealthy clients. These systems often include sophisticated pumping systems and advanced materials. While these systems are profitable to their developers, they are often far beyond the financial constraints of households in poor communities of developing countries. Today, engineers and scientists can harness solar energy with common materials and basic technologies. The simplest version is the batch solar water heater, consisting of a water tank, a dark absorber to capture the sun’s radiation

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air. The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575-49,837 exajoules . This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce

Solar power harness the sun 's energy to create electricity. Solar energy assets are enormous and boundless, and they can be tackled anyplace that gets sunlight. The measure of solar radiation, otherwise called insolation, coming to the earth 's surface consistently is more than all the energy at present devoured by every single human activity yearly [1]. Various variables, including geographic area, time of day, and current climate conditions, all influence the measure of energy that can engage in for electricity creation or heating purposes.

This article was written to inform people about solar power. It covers how solar power is produced, can be harvested, how it works, if it is renewable, the advantages and disadvantages of solar power as well as if solar power is feasible in South Africa which is related to my hypothesis. This article is not biased and gives both sides to using solar power energy.

The South African power crisis needs little introduction as most of us spend our nights in the shadows singing “Hello Darkness My Old Friend” and ‘’I’ve Got the Power ’’ in the hope that at some point the glorious rays of light will return. This energy crisis sees little end in sight and leaves the people of our country with a need and responsibility to find alternative sources of energy - solar power is one of these solutions. Solar power is a brilliant idea as it harnesses the power of the sun and converts it into electricity, however it is very costly and it is inefficient because only 11 - 15% of the energy harnessed is converted into electricity. Solar panels are generally fixed at one position, usually at the angle that one’s roof slopes or at some other predetermined fixed position. According to research, by moving the panel with the sun there will be a marked increase in the efficiency and power output of the solar panel. It is also claimed that temperature will affect the amount of energy produced. Thus, this project will aim to find out if there is a significant difference in efficiency as the sun moves around the solar panel and attempt to obtain the best possible efficiency by moving the panel with the sun throughout the day. By knowing this, it can be used by South African citizens to increase power, lower costs, lower the strain on ESKOM’s grid and improve their investment in solar panels.

The creation of solar energy requires little maintenance and solar electricity power plants produce zero emissions. Solar power plants use two different types of technologies: Concentrated solar power and Photovoltaic systems. Concentrated solar power plants, also known as “concentrated solar thermal”, uses solar thermal energy to make steam that is converted into electricity by a turbine. A photovoltaic system, also known as solar panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy.

Solar energy is the light and heat which are coming from the sun, and a human create them for his benefits since ancient time ago. Also, solar energy is the important kind of green energy. Moreover, humans have used them by using a range of modern technology that is constantly evolving. It includes harnessing solar energy technologies using thermal energy of the sun either directly heated or within converting mechanical movement or electric power, or to generate electricity through phenomena Photovoltaic (PV) using the panels of photovoltaic cells’ effort. In addition, a human has used solar energy architectural designs that rely on the exploitation of solar energy process, solar energy is a sustainable energy and is not implemented also it is a natural source of energy, and can be used to generate other forms of energy. As well, the great contribution is that solar energy will assure the other energy unsustainable sources such as oil and natural gas. According to Dickon and Matt “Coal, natural gas, and nuclear power, which today supply two-thirds or more of global power, are not about to disappear. But even at its currently low rates of market penetration, solar power has begun to shift the economics of electricity. This is the dawn of the solar age” (2015, para.28). Also, it will decrease using other sustainable

There are a few speculations about what would happen should Canada's population grow up to 100 million. Although that is quite a substantial increase from the approximate 36 million were currently at today; I personally don't believe that the construction methods for residential areas will change. When it comes to the building of houses it's all about speed and cost; Which is why I believe we'll continue to stick with the basic wood framed construction a majority of our houses are built with. The one way I could see housing change is if people continue to migrate to the hotspots in Canada such as Toronto, Vancouver and Montreal. Then we'll start to see more Non-combustible and fire resistant buildings built majorly out of steel and

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
