Solar power has been a very popular power source in 1970’s, but lost its popularity to fossil fuels due to the potential savings. Because of the solar energy was a major component in providing power to the space crafts as during 1960’s there was space industry made their first step in serious use of technological means in powering up space crafts. This led the solar technologies and reliability to advance and cost to be reduced. But solar power for non-space applications were came into place due to the energy crisis during 1970’s. Since then solar power has been in the energy field though it hasn’t been able to make a huge impact to the field.
When considering the present situation with the increase in energy needs people are starting to concern about finding alternative for non-renewable and environment polluting fossil fuels. Solar energy is one of the main alternatives. Solar energy is simply harnessing the energy of the sun. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. Through this process electromagnetic radiation and heat are created. Electromagnetic radiations including visible light, ultra-violet radiation, and infra-red radiation stream out into the space propagating in all directions.
Although only a little fraction of those radiations reach the earth that radiation is capable of supplying most of the energy requirement of the earth. But the practicality of doing so has to be
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
In just one hour, the earth receives more energy from the sun than the entire world uses during a whole year.
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.
Amazingly, the amount of enerygy that Sun shines down on the earth in one hour equates to the same amount of energy used by the worlds population in the entire year. Solar power should be used more than fossil fuels beacuse it 's clean and produces no harmful emissions. Easily renewable because it gets its energy from the
With 7 billion people across the world, renewable energy is one of the best options to avoid global warming, climate change, pollution, help save energy, water, nature, and wellbeing creating a healthier world to live in. Second, solar energy is another method that is completely natural and clean with barely any negative impacts on the environment and climate. It provides carbon free economy where pollution and carbon footprints are reduced, giving fresher air to protect the environment. Not only does solar energy reduce climate change but cools down the earth as well. Solar energy is a source from the sun lighting up residential and commercial architectural buildings. The system uses solar panels that are installed on the roofs, absorbing the sun into heat and transforming it into electricity. Solar energy can possibly change the way we use energy forever.
The sun has been playing a very significant role for earth and humans. It has been the producer of light and without it several things would not exist. Now another part that the sun is playing in humanity is being a generator of energy. The
Solar energy is the energy from the sun. It uses sunlight to produce electricity. These panels are usually installed on the roof and positioned to face the sun. Most countries all around the world use solar energy to reduce their dependence on fossil fuels and making it as a sizable share of their energy supply. Solar panels are used in large numbers by homes and offices to reduce their monthly electricity bills and reduces the need of electricity from utility companies.
A. Good things about Solar Energy. Nowadays, they think about the economics to how become it
Almost everyone has heard of solar energy already. Although it is very well known, it has to be used by many people. The biggest problem is the cost of solar energy. There are only a select few who use solar energy. Solar energy has many benefits, but when one sees the price of solar energy, they turn their head the other way. In the beginning, solar cells were extremely expensive to make. They were used in special applications, such as aircraft. Performance mattered more than the cost of making solar cells. However, it is less expensive to make. This is where the problem lies, how to increase efficiency while keeping the manufacturing at a low cost. The energy consumption of solar energy falls below one percent of total energy consumption.
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 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.
The use of sunlight is to supply the needs of humans like energy is a primary source to survival on earth. The sun’s energy is able to feed animal need’s. Only green plants are able to convert the energy from the sun into fuel and food. Most of our food and fuel are made through the sun with a process of photosynthesis.
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.
Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
Solar Energy are gathered from the sun and it can be used in modern power generation. The formation of the Earth's living organisms are primarily based on the sun to provide heat and light for them to survive. Since ancient times human beings learnt how to use the sun to dried items, such as dried fish etc. Now, solar energy are collected from Photovoltaic modules or in other words, solar panels. Electricity are generated with the Photovoltaic effect, which converts sunlight into electrical energy.
