The Importance Of Solar Energy Essay

1129 words - 5 pages

The sun shines upon Earth every day, yet no one thinks much of it. Solar power’s importance, though, is above what anyone could have ever imagined. There is active solar energy, which is when solar power is converted into light, heat, cause air-movement for ventilation or cooling, or store heat for future use. Less thought of, the other type of solar energy is passive energy, which most take for granted. Solar power provides life with heat, light, and now, electricity. Solar power also plays a role in 4 of the 5 areas of green technology: energy, green building, environmentally preferred purchasing, and green chemistry. All in all, solar power is quite a unique form of energy.

In conclusion, active energy is another type of solar energy.
One of the areas of technology that relates to solar power is energy. This category includes finding alternative fuels, new ways to make energy, and new ways to save it. The need for oil, coal, and natural gases are increasing, yet they themselves are running out, so it is essential to find replacements. There are many types of energy that can replace them such as biomass, geothermal, hydroelectric, wind power, and most of all solar energy. Solar energy is can not only be widely applied with some little adjustments in future technology, but is also unlimited unlike most of the other replacements. It will never disappear unless the sun itself dies out, which won’t happen for an extremely long time. This type of energy does not produce greenhouse gas emissions either, making it a healthy type of energy. Therefore, solar energy can be really helpful in the area of energy.
Green building is another area of green technology that includes solar energy. It is when green building strategies are applied to help both the economy and the environment. This includes methods from design, construction, renovation, and deconstruction. Solar energy is great in this particular area because it can help the environment greatly. Free of cost, passive solar energy can be obtained with a few modifications of the house. Solar energy from solar panels attached to the roof of the house can be used, which is very eco-friendly. Dark colored walls can absorb the sun’s heat and keep the house warm naturally rather than using heaters. As seen, solar energy plays a big role in green building, helping to reduce the harm to the environment.
The third area of green technology is environmentally preferred purchasing. This means buying products or services that have a better impact on the health of the environment. It applies to a lot of areas such as the raw materials, manufacturing, packaging, distribution, use, reuse, operation, maintenance, and disposal. Since the United States is one of the greatest consumers in this world, it is extremely important in this country. Solar energy relates to this area because after one acquires solar panels to collect solar energy, as long as the sun is shining, there will be plenty of energy. This is not only long term cheaper, but...

The power from the sun is what we call solar power. Solar

The Cost-Benefit Analysis of Solar Energy

3649 words - 15 pages resources we currently use, such as coal and petroleum, could be fully depleted within the next 25 and 100 years respectively (Byrd, 2012). Given that society has a tendency to over-consume natural resources, many economists have suggested that the use of alternative energy could alleviate the effects of overconsumption and the environment's ability to replenish. Therefore, this study evaluates the potential of solar energy (SE) on society and

699 words - 3 pages Solar Energy and the Energy Crisis Abstract The energy crisis is a major problem in the United States. Solar energy can help alleviate this problem. Enough solar panels to fulfill the energy needs of the entire United States would take up 27,347 km2 and cost almost 17 trillion dollars. Therefore, although there is enough space for all those solar panels, the economic cost is far too great. However, solar power can be phased in gradually
