A Brief Note On Solar And Alternative Energy

     Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing

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

Switching to solar and alternative energy is a clean, efficient way to save money and even raise the value of your home. The group is researching what converts sunlight to electricity and how it converts the radiation to flowing electricity. Selenium, a photovoltaic cell, was found to convert sunlight to electricity flowing into wires. The importance of this helpful technology, is solar energy is an alternative and will help provide electricity without harming the ecosystem and economy like paying for an electric bill would. After investing in solar panels, it would

It is interesting to note that when man was created, his needs were all around him. Some were obvious such as food and water, but other needs needed discovery like solar energy. Solar energy is the most ancient kind of energy known to man, however, man started researching it in the early 19th century.

For many years we depend on fossil fuels to get the energy and power we need to survive. Without it, it would lead to widespread panic due to the reliance on electricity to communicate with others, stay cool or warm, or even to turn on our lights. However, there has been the start of new energy sources that could not only help the environment but can also be renewed. The top two forms of such a discovery have been the emergence of solar and wind energy. Although both solar and wind energy are potential ways to reduce the number of fossil fuels used, there are major differences in their production, cost, environmental concerns, and availability which can make one superior to the other (Clean Energy Partners 2011).

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

Populations have increased and so have the energy demands. Various forms of pollution have increased as countries industrialized. Electricity generation by industries emits soot mass, sulphate aerosol and water vapor into the atmosphere thus contributing to the ever increasing pollution. Most counties rely of fossil fuels like oil and natural gas to sustain domestic energy needs. This trend is being reversed in both China and Saudi Arabia with both embracing solar energy. Solar energy has proved to be the best option for electricity generation and the best choice to replace the oil . Producing electricity from solar energy is cheaper as compared to conventional power production.Solar energy ensures both economic and environmental sustainability .However , is it possible for the solar energy to be the most reliable source of energy? , And if it is possible what is the best sloar panel?.

Solar Energy has amazing potential as a primary source of energy with a host of benefits. The sun provides vast amounts of free renewable energy that should be harnessed. A realistic Solar Energy Policy should be defined and pursued vigorously. The capture of the sun’s energy is underway but supplies only a small fraction of our current energy requirements. Non-renewable sources of energy have been the primary source of energy production throughout the industrialized world. Fossil fuel technology drives most of our economy. We power our cities, industries, and cars with petroleum based products such as gas and heating oil. In some areas there is still reliance from coal to generate power and heat. One downside if we keep using non-renewable resources there is a chance we could deplete these resources. Solar radiation could be seen as an ideal energy source, as it is abundant, free and essentially limitless. Shifting from non-renewable resources to renewable resources could be beneficial to our society. Just as certain climate factors affect air pollution, air pollution can alter the climate. Global warming has transitioned into global climate change, shifting from average weather conditions as a result of natural and human factors. Predominantly caused by human activity, the formation of an aggressive solar energy policy would help to reduce both pollution and it reduce the dependence on imported fuels. This

Living organisms are dependent on energy. Chemical energy is formed through the conversion of sunlight by organisms such as bacteria and plants. It is through this process that food is formed for other organisms. Nature only consumes the amount of energy supplied by the sun. A part of the solar energy consumed by nature (animals, plants and their habitats) is transformed into chemical energy and is sealed off eternally from the atmosphere, stored as biomass.

As we all know, fossil fuel energy comes from wood and some organic materials from millions years ago. They experienced slow chemical process and became the coal and raw petroleum as we see today. However, since the first industry revolution, the speed of mining fossil materials and consuming all kinds of oil products has been accelerating in a geometric growth. People use coal to generated trains, and they use fuel to generated the majority of their engines, which includes cars, aircrafts, and heating machine. We have billions of people on earth right now, and everyone needs to consume energy for transportation, lightning and many fields in various ways. Where do the energy come from in the past three hundred years? Absolutely from the fossil material. But fossil energy is not unlimited, it has a maximum. When we consume it till the edge, then we have nothing to generate our machine. Luckily, solutions are always more than the problems. We create the way that is called renewable energy. It helps us retrieve energy from nature, like solar, wind, and water. These kinds of energy are unlimited, relatively, which means if the sun doesn’t fall down, the oceans aren’t dry, we can get power from them. However, even though it has a bright future, we still have many obstacles needed to be solved. (Hepbasli & Alsuhaibani 2011)

The energy availability plays a vital role in economic activity because production and manufacturing can be fulfilled by energy consumption only. Nowadays low cost energy is necessary for economical development of any country but because still the major energy extraction is possible using fossil fuels and those countries which have not sufficient amount of such fossil fuel facing lot many issues related unemployment; but the solution of this energy crisis is available from alternative energy sources like solar energy, wind energy and bio mass and bio fuel etc.

The source of all energy here on Earth comes from the sun and without it there would be no climate here on Earth (Kitchen, 2014). Our Earth’s climate can only be balanced by the amount of energy that is coming and going. When the rate of incoming and outgoing energy is not balanced, this causes issues with out climate. Nuclear fusion is the process by which our energy is created from the sun and converts hydrogen to Helium. Pressure and temperature within each layer of the sun causes energy to radiate outwards into space and then in time, it will radiate to Earth. According to Kitchen, this process can take thousands of years to process, but only takes about eight minutes to reach our Earth’s surface (2014).

Humans are destroying Earth’s atmosphere with the use of fossil fuels. Solar panels are a fantastic alternative, and could save our planet. In 1977 Jimmy Carter began his term as President of The United States. Carter, a firm believer in solar technology, decided to start immense studies about solar energy and it’s benefits. He did so in hope of convincing congress of passing a bill to encourage investing in solar energy with the help of government funds. Such studies received funding of the amount of $124 Million in 1980; Needless to say, this was a huge step towards creating a nationwide movement to sustain renewable energy sources with low pollution outputs.

The search for cost effective and efficient renewable energy is becoming an increasingly important area of study. According to Sampaio, “with the increase of population and technologic and economic development, human beings need more energy to create a better life environment.” Fossil fuel energy sources, while cost effective, have major environmental impacts that add to global warming, acid rain, and climate change. One renewable resource that is sustainable and readily abundant is solar energy, which is a reasonable and readily available replacement for fossil fuel energy sources globally.

There are many forms of renewable energy . Most of these renewable energies depend in one way or another on sunlight. Wind and hydroelectric power are the direct result of differential heating of the Earth 's surface which leads to air moving about (wind) and precipitation forming as the air is lifted. Solar energy is the direct conversion of sunlight using panels or collectors. Biomass energy is stored sunlight contained in plants. Other renewable energies that do not depend on sunlight are geothermal energy, which is a result of radioactive decay in the crust combined with the original heat of accreting the Earth, and tidal energy, which is a conversion of gravitational energy.
