Essay On Sun Based Energy

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.

In a growing world, electricity production is becoming a problem due to coal fired electrical plants releasing millions of gallons of greenhouse gases, ecological problems with pollution in water, and health risks concerning workers and people living nearby. But with new technology and advances in renewable energy sources, wind energy is becoming one of the most popular energy sources for many states.

     Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing

One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.

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

The wind turbines are made and created from a local power plant in Valeria and it helps create kinetic and solar energy. The Wind Power is sustainable because wind turbines are a conversion to kinetic energy and the wind is mechanical power. But the

Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent

Wind turbines are becoming more and more popular across the flatlands of America. Along the same lines as solar power plants in California, there are many issues with wind turbines. Wind turbines are massive towers with a swinging blade that can create wind of up to 100 miles per hour over an acre of air. Turbines require a massive amount of tree removal, roads to be resurfaced and sometimes rebuilt (to access the intended installation area), lots of heavy machinery, digging into bedrock so as to create a good foundation for the tower. It takes 15 to 20 turbines to make it efficient, so it makes all

Everyone knows that the wind is one of the most significant factor of weather and climate because of its role in influencing the distribution of energy and moisture between the parts of the globe. Recently, people have begun to exploit the wind energy which is witnessing the fastest growth in the world. In fact, this source of energy is growing rapidly in all parts of the world. So, most of governments are trying to use wind power for different aspects. In addition, two decades of efforts to achieve technical progress has led to the production of very sophisticated wind turbines which are adjustable, easy and quick to install. Wind power may have many disadvantages, but the advantage of wind energy is more than the disadvantages. So, there are many environmental advantages of wind power such as renewable source, reduction of greenhouse gases, reduction of water consumption, and taking a small space in the land.

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the

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

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.

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.
