Introduction In 21st century almost all devices work with electricity. Electricity makes activity of people easier and more comfortable. Moreover, it plays a great role in development of medicine, science, education, transport and other spheres of human’s life. However, electricity production is becoming more and more problematic because the biggest part of energy for electricity is produced by natural resources, which are neither infinite nor renewable. It means that one day mineral reserves can run out, and, as a result, there will be risk of possible energy crisis. This situation stimulates humanity to transfer to renewable power system. Countries around the world are promoting sustainable energy policies, particularly to reduce …show more content…
Moreover, there are almost 3000 hours of sunshine per year, while energy from solar radiation is 1500-1800 kW/m2/year (Energy Sector Management Assistance Program (ESMAP) 1997). Despite the very appropriate conditions for realization of solar energy, this resource is little used. So, Kazakhstan should pay attention to the adoption of renewable energy-supply system to the daily life and make a compelling choice between photovoltaic technology of converting sunlight into usable form and concentrated solar thermal plants in an economically and environmentally advantageous way. Hence, this paper will evaluate to what extent is solar energy suitable and viable source of carbon-free energy for Kazakhstan. Also different types of technologies necessary to make the conversion of solar energy into electricity will be examined, particularly concentrated solar power will be considered as a possible solution to the existing situation and possible energy problems in Kazakhstan. Main Body Dependence on coal, oil and gas and other natural resources pose a threat to the future with air pollution, changes in climate and economic instability due to the fluctuations of fuel prices. Instead of wagering on unreliable fuel materials, people should learn how to use planet’s infinite sources of renewable energy effectively. Solar energy is recognized as the most promising alternative energy in the world. The popularity of sunlight energy is attributed with inexhaustibility of
As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.
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.
Decision-making is at the core of the United States Supreme Court. The justices are not immune to possessing political ideologies and similarly to the American public, those ideologies impact their lives to varying degrees. The facet of judicial politics explored in this paper is decision-making and the impact of ideology. While it would be ideal for the Supreme Court to have zero influences other than the constitution, it is also wishful thinking. Author Jeffrey Toobin agrees with political scientists that the justices of the United States Supreme Court make decisions and rulings that are a result of their ideologies and personal values. He says, “All justices have a political ideology as well as a legal philosophy--- that’s a big reason presidents choose them in the first place.” Perhaps the most astute opinion on this matter comes from Justice Sonia Sotomayor:
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.
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on
Frozen toes and red ears. Pink windburned cheeks and chapped lips. Can you feel it? The rush of cold winter air over your face. Can you picture it? A winter wonderland with slopes, lifts, and free people. Spotlights shining down on you and illuminating the glistening snow. Sundown, a place people go for thrills and fun during the winter. Not everyone departs with a good memory in mind. If you’re not careful you might leave with something unexpected.
Tom Sawyer is an adventurous boy who gets into mischief and trouble, but learns from his mistakes. Although in the beginning of the book, he was a troublemaker and was always yelled at by his Aunt Polly, in the end, he became a young man and was more mature than ever.
The Sun is one of the most significant sources of renewable energy. In one hour the Earth receives enough energy from the Sun to meet its needs for nearly a year. A Photovoltaic (PV)
In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.
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
Energy play a vital role in our day to day life. We can’t think our life without energy. Everyone who is existing on earth want energy for surviving his life.Today our world’s population is in order of billion and it is continue to increase very rapidly so, our demand for energy is increasing drastically in recent time. Our conventional source of energy like coal, petroleum
The energy availability plays a vital role in economic activity because production and manufacturing can be fulfilled by energy consumption only. Nowadays low cost energy is necessary for economical development of any country but because still the major energy extraction is possible using fossil fuels and those countries which have not sufficient amount of such fossil fuel facing lot many issues related unemployment; but the solution of this energy crisis is available from alternative energy sources like solar energy, wind energy and bio mass and bio fuel etc.
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
In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best
That great ball of fire up in the sky that we call the sun is the ultimate source of much of the power that is generated and used by man. Solar power is full of potential and has many benefits of which some are obvious and a few others that are not so easily realized by us. In fact, the sun has
