Solar Energy Can Not Harm The Earth

According to Source B, solar power is defined as the collection of solar radiation to produce electricity. While the energy of the sun is free and abundant, debates have grown whether or not it provides for our energy needs. Is solar energy clean or does it pollute our environment. Solar energy is the answer to the Earth’s energy needs for the future because, it will get cheaper, be more efficient, and it produces no pollution during operation. First, solar power energy will soon be cheaper. While others may say that the installation is expensive, will become cheaper throughout the decades. Source C says that we will hit a peak in oil where we will start exporting as oil prices rise. This means as oil prices rise, solar energy will become cheaper.

The largest obstacle solar power has to overcome is cost. Solar power has high startup costs. Stated in The Future of Solar Energy, “Currently, the estimated installed cost per peak watt for a residential PV system is approximately 80% greater than that for a utility-scale plant, with costs for a typical commercial-scale installation falling somewhere in between.” These cost estimates often “include costs for inverters, racking and installation hardware, design and installation labor, and marketing, as well as various regulatory and financing costs” (The Future of Solar Energy). Many do not want to pay for the upfront costs of instillation of solar energy devices when an alternative energy supplier is already in place. In order to successfully reduce our carbon emissions, governments must become involved. Federal money must be allotted to the research and development of solar power for it to become a viable energy source. In doing so solar power will become less privatized and potentially more affordable. There has been recent growth in the solar energy due to “a 50%–70% drop in reported PV prices (without federal subsidies) per installed peak watt”, and a “current federal tax subsidy for solar generation: a 30% investment tax credit (ITC)” (The Future of Solar Energy). The reduction of PV prices and a tax credit is a positive aspect for solar power, but the prices are still too high for the masses. The value of a renewable energy source is frequently lost when

Even though only a small amount of the sun’s heat ever reaches Earth, it is enough to power the whole world. Solar energy is always being provided to us by the Sun. Solar energy can be converted into electricity and heat. It helps provide the warmth necessary for people, plants, and animals to survive. With the help of today’s technology, scientists have found a way to use the sun to help us in our everyday lives. The idea of solar energy has, resulted in the use of solar power. Thus, it could lead to a more modernized and efficient society. Solar energy is a renewable resource and is converted to electrical energy in two ways: by using photovoltaic materials or the thermal process. The photovoltaic method, generates electric power by using the solar energy to convert energy from the sun into a flow of electrons. (Sethia, et al., 2017). The thermal method is a process that uses the energy from the sun to heat a working fluid in an electric generating cycle. Solar energy is one of the most important sources of energy we could have because it is a non-polluting energy. This, in turn, helps in lessening the greenhouse effect. The most popular way to use solar energy is through the use of solar panels. To generate the high temperatures necessary to make steam to generate electricity, the sunlight must be concentrated. Solar thermal technology often uses reflectors in the form of parabolic concentrators or flat mirrors to focus the sun's rays onto a water-filled pipe.

With benefits comes the drawbacks -the two major disadvantages to using solar power include the price of solar power and finding suitable sunny locations. While the “primary disadvantage of current solar technology is the up-front cost of the equipment. Because of the investment cost, solar power remains the most expensive way to produce electricity.” (Withgott & Brennan, 2011. p. 599) In the United States, it could take as many as 20 before a

The sun has been an important part of civilization since ancient cultures roamed the Earth. Groups of people throughout history have worshiped the sun for allowing their crops to flourish, either by creating places to praise the sun or observatory areas to gaze upon it. Without the sun, life as we know it could not exist. The heat released from the sun is comparable to the amount of energy released from burning trillions of tons of coal per day. United States coal plants are held accountable for releasing numerous harmful chemicals into the atmosphere and soil, including: carbon dioxide, mercury, and lead. In order to reduce the harm done to our planet we must use other methods of energy production. Solar energy is the most efficient and cost-effective solution for the ever-growing problem of overusing resources and polluting the environment.

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

At the first glance, solar energy seems like the most practical solution to our energy needs. We receive heat from the sun, which provides us with energy needed to keep us going us on forever. It has been estimated that the Earth receives over 173,000 terawatts of energy every year, which is more than 10,000 times of what we need. Despite the abundance of solar energy, the challenge has always been collecting the energy. Although people were aware of photovoltaic cells (PV cells), solar panels have proven to be expensive to them firmly. The high costs of the solar panels and the high costs per square inch of the panels have made solar power economically unviable.

In the last decades energy consumption have come to a time where people started noticing the climate changes and the effect of fossil fuel energy for been environmentally destructive, by producing pollutions and other effect. After realizing the effect engineers come up with solar panel, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panels which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel solar panels are less harmful for the environment. From it creation few decades ego, just recently solar panel started getting popularity in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price have changed dramatically since then. Even though scientific data shows that solar energy is a better alternative to fossil fuel, many people still wondering about global warming, the benefit and the necessity of solar panels

Sunlight is everywhere and the resource is practically undying .It is readily abundant to us. Solar radiation is the most plentiful energy source on Earth and sufficient to meet the present global energy needs. According to Patil (2010), fossil fuels have the limited sources and have the r/p ratio of

For those who don 't know, solar energy is radiant energy produced by the sun and can be captured through semi conductors to use the energy. Solar energy is used in many parts of the world and has become very poplar today. The history of solar energy goes back to the 1769’s when a “Swiss scientist named Horace-Benedict de Saussure created the first solar collector which was an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely know as the first solar oven, reaching temperatures of 230 degrees fahrenheit.”(7). This complex system of collecting sunlight to create power for all sorts of things became extremely popular and the industry started to boom. An article from solar energy history states that, “In 1947 following the second World War, solar power equipment started being popular among many people in the USA. There was a huge demand of solar equipment.”(7). After this boom

Renewable energy resources are clean because they not only come from the environment but there is no need to change chemically the source in order to get usable energy. The sun for instance gives off heat, which warms our planet. This same heat can be used to warm water pipes, which can heat a business or home. This definitely requires no equipment to acquire this energy. The sun as a resource can also excite particles in a solar collector. According to Merriam-Webster dictionary, solar collectors are various devices used in the absorption of solar radiation to heat water or produce electricity, (Dictionary and Thesauras - Marriam-Webster Online, 2007-2008). These excited particles generate electricity. There does not necessarily have to be direct sunlight, for this process. Even on a cloudy day, energy can be produced though lower than on a sunny day. Since the sun will be here for another million to billion years from now this process can continue forever. Using the sun as an energy source means that no pollution will be generated from it being converted into usable energy.

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.

On the basis of every day, every hour, the sun beams on the ground more than enough energy to meet the world 's energy needs for an entire year. One of the types of alternating energy, solar energy is a technology used to harness the sun 's energy and make it usable. Today, this technology produces less than one tenth of one percent of global energy demand.

Solar energy comes from the sun and many living organisms depend on solar energy, like plant, aquatic life and animals. Solar energy is mainly used to generate heat and light. “Solar energy coming down to the planet is affected by the orbital path of the sun and its variations within the galaxy” according to Rinkesh. Rinkesh also wrote that solar energy was “believed to have been responsible for the breaking of ice during the ice age, which creates the separation of lands and sea.” Anyway about seventy percent of the sunlight gets reflected back into space and thirty percent of the sunlight to create energy for the nation's energy demands. There are two kinds of solar energy, the active solar energy and passive solar energy. Passive solar energy uses duration, position and sun’s rays intensity to its advantage in heating a particular area. Active solar energy uses electrical technology and mechanical technology. Solar energy is an effective alternative for fossil fuels because it does not create pollution and is also renewable.

The most common form of solar energy used today are photovoltaic solar panels, which absorb the sun’s light to create electricity. These solar panels can be attached to homes as a primary or secondary source of electric power. They can also be used for small appliances and machines which only need small amounts of electricity for use. Large scale photovoltaic panel plants have also been constructed to provide power to many homes.
