Pro Choice I Historical Backgrounds
The history of solar power reaches back in time, way back in time, you would think that solar power is a relatively new concept but it’s been used for a long time now. It is definitely not new by any stretch of the imagination. As early as 7 BC the suns energy was being used, ancient people would try to face the south side in order to get the warmth as possible from the sun's rays. These are just a few ways that solar power was explored and harvested by our ancient ancestors. The Greek and Romans used solar designs. Just like

Why do we need it? Will do you want to have a global climate change and limited resources of coal and fossil fuels? Solar energy is a very reliable resource that doesn’t pollute the atmosphere and causes damage to our planet. Solar energy, a renewable energy source since the 18th century has given positive effects worldwide. Wind power is reusable and effective that can be very useful. Fossil fuels and other harmful gases that hurt the environment would be and should be replaced by solar panels for the greater good of this humanity. Power plants, factories, coal, and gases are hurting this planet and those living on it, harmful chemical are being dumped in the ocean just to create electricity and power, if we replaced them with solar panel fields we could create enough energy and electricity for the whole plant to use for free off of the suns solar …show more content…
There is many good things about solar energy, one of course is that it doesn’t release any pollutants into the air. The use of solar energy for homes and businesses can help reduce the intake of fuel that we would otherwise be used for heating, further reducing carbon emissions and the output of pollution. Solar energy is about as natural as source of energy any one could receive or get. Energy from solar panels is sustainable and renewable, unlike some of our major sources of energy that is being used today. Today solar energy can be used in many applicants like electricity, evaporation biomass, hating water and for transport even, such as solar cars. Being environmentally friendly is a good and helpful thing for the environment, compared to fossil fuels which will release greenhouse gases, solar energy is the way to go, and this could play a role in electricity that the world needs in order to sustain global
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in.
NASA have done studies to prove that the sun is going to be around for 6.5 billion years, so why waste it. This means we have plentiful energy sources we just need people and governments to invest in it.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
for our environment? People are starting to second guess solar energy but it is still used and
“By 2050, one-third of the world’s energy will need to come from solar, wind, and other renewable resources” (www.altenergy.org). America can no longer rely so heavily on nuclear energy. America needs to harness the energy found within natural, renewable resources. In fact, nuclear energy needs to be phased out completely because of its negative impact on health, the environment, and its overall cost.
Wilhelm Hallwachs discovered that combining copper and cuprous oxide produced a photosensitive material in 1904. In the next year, Albert Einstein completed his work on the photoelectric effect and presented his paper on it. However, it was William G. Bailley of Carnegie Steel who created the present basic design of the solar panel consisting of copper coils and an insulated box. The period after the Second World War saw increased demand for solar power as energy needs went up and supplies could not keep up. There was an explosion of passive solar buildings in the country and that spurred more investments into the solar industry. It was at Bell Labs that the silicon photovoltaic cell was developed by Daryl Chapin, Calvin Fuller, and Gerald Pearson. It was the first cell that stored enough energy to run contemporary electric
Once this happens, solar energy, wind, Biomass , hydro, and geothermal energy will slowly start to be incorporated into everyday power and energy sources. Everything will become more high tech and advanced. There would be more stable prices and more reliability on the power source since it is renewable. We will never run out of these power sources. Carbon is a non-renewable energy source and there will be an end to it, which is why switching to a reusable energy source would save us the carbon we might need in the future.
Our challenge topic is to make solar energy more economical. By doing so we need to make solar energy more efficient. Although the sun provides a lot of energy, we are currently only able to efficiently convert 10 to 20 percent of it into electricity. This topic is very challenging because costs of electricity that is provided by solar energy is around 3 to 6 times more expensive than the current prices of electricity. Storage is another problem that we face because it 's rather hard to storage solar energy, unlike storing other sources of energy like heat. This challenge exists because fossil fuel produces toxic waste such as carbon dioxide which pollutes the climate we live in. Fossil fuel which is our main source of energy will one day run out and we will need solar energy to replace it. Solar energy produces no waste, and with no harmful leftover. “Solar energy is radiant
Claim: Solar power has the potential to become the United States main supply of energy and replace are needs for more conventional and harmful forms of power generation.
Solar is a viable alternative energy source with solar panels becoming more affordable and more efficiently designed.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
The Earth captures around 342 W/m2 of energy from the sun. This energy is in the form of solar radiation, which the atmosphere reflects about 77 W/m2 and will absorb around 68 W/m2 of solar radiation annually. Therefore, the Earth’s surface is receiving, on average, about 197 W/m2 of solar radiation annually. This amount of energy received is roughly more than 10,000 times the amount of all energy humans consume per year. This energy can be used to produce electricity or heat. This energy source is not being used to it’s potential considering how much effort would come into effect to store and transport this energy.
Solar energy is that energy which is gets by the radiation of the sun. Solar energy is present on the earth continuously and in abundant manner. Solar energy is freely available. It doesn’t produce any gases that mean it is pollution free. It is affordable in cost. It has low maintenance cost. Only problem with solar system it cannot produce energy in bad weather condition. But it has greater efficiency than other energy sources. It only need initial investment. It has long life span and has lower emission. The sun is the original source of almost all the energy used on earth. The earth receives a stock ring amount of energy from the sun, as much energy falls
When the sun heats the panel, it generates clean energy, which does not pollute the environment. All in all, the costs of solar power might not be applicable when it is certainly the best way to have a clean environment.
