~Some history, types, and facts~
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 fossil fuels.
Using the sun for its heat and energy is not a new idea. It has been around for thousands of years. The first record of sun being utilized for energy and heat dates back to 400 BC. The Greeks designed their buildings and oriented their houses to utilize the sun during the winter and obscuring its hot rays during the summer. The Romans then continued on with harnessing the suns energy by developing window glass that allows the sunlight to come in, but traps solar heat. The Romans even put the sun in their legal system as to make sure that every house had so much access to the sun.
The first solar water heaters came into play in the 18th century. A French-Swiss scientist in Maryland did an experiment to see how much heat window glass would actually trap. By building a box and putting different glass tops on it, he learned he could reach the boiling point inside the box. Another person developed this idea and decided to put tanks of water into them, and sure enough that w...

- Solar energy is solar radiation or sunlight that’s given off by the sun. Alexandre Edmond Becquerel discovered the photovoltaic effect which is how electricity can be generated from sunlight, but the solar cell wasn 't invented until 1941 by Russell Ohl. which creates electricity or heat. Solar power cells convert solar radiation or sunlight into electricity, using the energy of photons to make an electric current within the solar panel. The electric current then flows out of the solar panel into an inverter that converts the DC power into an AC power, which is then used by the population....

- Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy, which is not such a bright idea since nonrenewable resources, such as oil, coal, and gas, are limited (Eia 1). Most significant uses of coal are in steel production, electricity, cement manufacturing, and as a liquid fuel. Solar energy is one of the least used energy sources we have access to in the world; it is also one our mother Earth is relying on to save the nonrenewable fuels, such as fossil fuels....

- The sun is a vital part of life on Earth. Plants need sunshine to survive and proceed with photosynthesis, the water cycle is powered by the heat the sun gives off, and walking outside on a sunny day can cause people to feel rejuvenated. In addition, the light that the sun gives off has the potential to become the predominant source of energy for society as it exists today. This is because solar power is a form of energy that can be harnessed in a variety of different ways, has the ability to provide for a diverse range of needs, is becoming more affordable at a rapid rate, and is completely renewable....

- According to my research about solar energy I recommend that FPL develop more solar energy production facilities and assist individual homeowners in applying solar panels to their homes. My recommendation is based on many factors. One of the major factors for considering solar energy is that Florida is almost always sunny. There are about 8 hours of sunlight for a normal day and it seems logical to harness the sun’s energy for our needs. When storing solar energy it makes more sense to connect to a utility grid and sell the excess power to a utility company because the batteries that store solar energy are very expensive and large....

- “In Table 1 basic criterion are collected to get a better overview of the main characteristics of each source. The overall status of solar energy is positive because of the high amount of energy available, variations of gained energy types and low impact on environment. Very important, in this case, is the establishment in small scale, in means of good possibilities to use this source for personal use. The price factor shows the average situation now, but it is variable with the tendency to decrease for most of the sources with the lapse of time.... [tags: Solar cell, Photovoltaics, Solar energy]

- Future of Solar Energy Solar energy technologies (SETs) supply energy with less environmental hazards than oil, natural gas or coal. SETs are often overlooked because of initial start-up costs and aesthetics. As technology progresses, the costs are projected to decrease, thus becoming more accessible for businesses and homeowners alike. Even in the states that are prone to prolonged overcast or cloudy weather, the use of solar energy is still viable because it will cut down on the need for pollution-excreting fossil fuel power plants....

- At the bottom of water is plant matter. That is what coal starts off as. It is covered in sediments and eventually goes through metamorphosis. After metamorphosis, it eventually becomes coal, which is one of the three most important resources on Earth. Another resource is solar energy, which is now being widely used in a variety of ways. Panels and sun light are what is used to collect this type of energy efficiently. The third type of energy resource is water. This type of energy can be conserved when a plan is implemented....

- Solar Energy What do the bubonic plague in the 14th century, the influenza epidemic of the early 20th century and the spread of HIV/AIDS in the late 20th and early 21st centuries have in common. One answer, according to Joel B. Stronberg author of the American Solar Energy Society’s “Common Sense,” is that they have all been called pandemics. According to Merriam-Webster.com, a pandemic occurs over a wide geographic distribution and affects “an exceptionally high proportion of the population.” Joel B....

- Someday, our energy sources are going to run out. What will we do. What can we do. Our major source of energy now is fossil fuel. If that were to run out, there must be an alternate way to get energy. Because of this problem, there has been a lot of research going on. Through that research, alternate ways to get energy have been developed. They include wind energy, solar energy, nuclear energy, tidal energy and many more. In this paper I will focus on the aspects of solar energy. I will look at the history of solar energy, cover the advantages and disadvantages of solar energy and then finally I will talk about the concept of solar energy (how it works) and ways that solar energy can be use...

- Solar Energy There is a bright future for solar power (no pun intended). On the average sunny day the sun shines approximately 1,000 watts of energy per square meter, enough energy to power all of our electricity needs and excess(“How”). This plethora of power and will be utilized in the future because we can't afford not to. It is predicted that in 100-500 years our fossil fuels will be depleted: this means that alternative sources of energy will be a necessity (Exxon). We consider solar power a renewable resource because it is conitinuosly supplied to us by the sun.... [tags: Renewable Energy, Solar Power, Environment]
