Solar Energy Facts

This article will address some of the most intriguing solar energy facts. Solar energy is generally one of the most ecologically sound and desirable sources of power these days. Let’s get going with the obvious. Solar power has been in existence since the dawn of time. It has been used by microbial, plant, and animal life as a primary energy supply. Plants, using photosynthesis, create nearly all of the food on the earth and are at the base of the food chain. Furthermore the fossil fuels we rely on so heavily nowadays are created from plants and animals that lived a long time ago. Only in recent times have human beings been able to capture solar energy so that it may be utilized any time of day and night, and in any weather, stored and transferred.Annually, the earth’s atmosphere absorbs 3.85 million exajoules of energy from our sun. This most likely doesn’t mean much to you, however by comparison, the entire use of electric energy by all people today around the world is just 56.7 exajoules per year. This indicates that within a few hours, the earth receives more energy from the sun than people expend during an entire year! Solar energy is a remarkably clean supply of energy simply because, in contrast to fossil fuels, making use of this kind of energy doesn’t discharge carbon dioxide or other types of harmful toxins into the environment. Furthermore solar energy is collected by almost every single form of life. You’ve almost certainly never seen a reptile collect wood to start a fire, but you most likely have seen one lying on a rock to absorb solar energy. Solar power is probably the most environmentally sound energy option attainable right now.Perhaps you may be wondering what exactly solar power is capable of doing for our environment. Every year, humans consume 467 exajoules of energy by utilizing several principal power sources: burning coal, gasoline, and oil, along with ‘green’ sources like wind, solar, and hydro energy. However, if we could capture just 10% of the sun’s energy, we would have the capacity to replace all of the fossil fuel sources and have enough space for growth. Without any doubt solar energy facts like this make it clear how much better solar power is for the environment and how great the potential is for solar energy development.Considering that you’ve seen some of the most remarkable solar energy facts and now have an understanding regarding what solar energy can possibly do for the environment, you’d probably want to know just exactly what solar energy is. To put it simply, solar energy is the heat and light energy emitted from the sun. The sun constantly generates vast quantities of energy into our solar system. Approximately 30% of the sun’s energy that reaches the earth is immediately deflected by the atmosphere, and another 20% is absorbed into the atmosphere. However, around 50% of the energy actually reaches the earth’s surface, where it fuels photosynthesis in plants, maintains both hot tropical and warm temperate climates, maintains the temperature of the ocean, and generally speaking keeps our planet alive. All of this is accomplished without creating any pollution or destruction of natural resources.A lot of people don’t understand how solar energy functions on the technical level, and so they wonder just what solar energy is going to provide to their homes, businesses, and communities. In the last three decades, solar energy technology has developed at an accelerated rate. Solar energy is gathered at a number of large power plants in the U.S., Spain, Australia, and in other nations, where it delivers power directly to the power grid. This implies that countless houses around the globe already get electrical power generated by the sun. One of several lesser known solar energy facts is that solar power can also be employed on a considerably smaller scale. Solar panels on households and businesses, can certainly create a percentage (or possibly all) of the power these buildings have to have. On an even smaller scale, solar panel systems are put to use in India and Indonesia to disinfect water, and compact solar burners and ovens are often employed in order to cook food in other regions of the globe. Solar energy might be employed to power practically any procedure you can visualize, from large-scale power generation for towns and cities to boiling a single pot of water.What makes all of these different uses achievable is the development of solar energy systems. You will notice two standard varieties of solar energy technologies presently used today: solar thermal energy (STE) and photovoltaic (PV) energy. Solar thermal collectors just harness the heat or thermal energy generated by the sun. This thermal energy is generally used to heat water which in turn can easily be stored and used for common every day requirements or piped to a household heating system. STE may be stored by heating up or energizing a thermal mass that is designed to continue to radiate heat even when the sun isn’t shining. Solar thermal collectors actually are significantly more efficient in comparison with photovoltaic collectors but on the other hand energy storage is somewhat more cumbersome. Photovoltaic solar panel systems produce electricity when exposed to sunlight. This electric current may be used immediately or alternatively stored by using batteries for later use. This is actually one of the more significant solar energy facts whenever you are dealing with PV energy systems. Battery storage is incredibly significant since it means it is possible to store solar power for use through the night or during cloudy or rainy days.Solar energy is a very important alternative power source which can help us take care of our environment. It can also help to cut down our reliance on fossil fuels. You may be asking yourself just how big of an expense it is going to be for you to convert to solar power? Solar power is not really as costly as most people think. A total solar energy system for a house can potentially cost more than $30,000, having said that this does not really mean you will be paying that total amount. To begin with, you will discover lots of different incentive plans, which include tax credits, rebates and grants, that may reduce the price of installing solar panel systems by 30% or more. One other option you might wish to look into is a smaller solar energy system that just supplements your household power needs. A smaller sized system will cost considerably less, while still lowering your current energy bills, and it will certainly help make your home much more environmentally sound. Currently most electrical power is generated using fossil fuels. So lowering your use of electrical power from the area power company by 50% is actually an important step towards establishing a sustainable power grid.In this article, we’ve made an effort to supply you with a number of helpful and thought provoking solar energy facts. While you contemplate these facts, also think about just how much value you put on the quality of the environment and on humanity’s ability to preserve it. No matter if fossil fuels do not run out during the next 50 years, it’s very likely that their continued use as our primary energy source is going to wreak environmental havoc. Investing in solar power now might not instantly help you save money, but your monetary investment can certainly provide an improved future for everybody under the sun.

The Advantages of Solar Energy – Why Going Green Is Not Only About Protecting the Environment

There is no doubt that reduced pollution is one of the greatest advantages of using solar panels. You do not need to be a fervent ecologist to realize the severity of the environmental problems that affect out world today. The fuel crisis, the pollution, climate changes, all these issues affect us one way or the other. There is no point in denying either their importance, or our responsibility in triggering and maintaining them.But the advantages do not limit to environmental effects, although they are incredibly relevant. There are many other benefits of using solar energy that refer to costs, maintenance or energy independence. Whether you are interested in this energy source because of a profound environmental concern, or you are more attracted to the idea of low-cost energy and money saving, going solar can prove to be a remarkably smart idea.Below you will find a comprehensive list containing the most relevant reasons why using solar energy is beneficial, so you can have a more complex image of the reason that makes it a viable and attractive alternative to fossil fuel energy. With a wider perspective than before, you might be able to make a wiser and more informed decision.1. Protecting the environmentWe start the list of advantages with the most prominent one, the environmental benefit. There is no secret in the fact that overexploitation of the Earth’s non-renewable resources will eventually lead to their paucity, to higher costs and extreme pollution. We cannot rely forever on fossil fuels to create energy, because this resource will eventually disappear. On top of that, continuing to burn fossil fuels will lead to even more pollution than today, and this will affect the climate and people’s health. Turning to a clean, safe, healthy and renewable source or energy becomes imperative.a) Solar energy is renewableOne of the first advantages is the fact that it is a renewable source of energy that we can count on for billions of years from now. The sun will keep shining. Using its power will not diminish it, like in the case of fossil fuels. When the Earth will not be able to count on fossil fuels for energy, the Sun will still provide enough power for the whole world.b) Solar energy is cleanUnlike fossil fuels, it is not polluting. No gas emissions, no unpleasant smells, no smoke – it is totally clean. Considering the growing problem of the greenhouse effect and the climate changes it triggers, finding cleaner sources of energy is the best way to protect the environment and reduce the negative effects fossil fuel energy has on the atmosphere. Choosing solar energy over non-renewable energy means more than simply protecting the environment. It means protecting ourselves and the generations to come. Fighting for a healthy, safe world implies stopping climate changes, global warming and air pollution.2. Low costsCertainly, solar energy is environmentally friendly. But, as we already mentioned, the advantages do not end there. Probably the most appealing advantage of all is the low cost. Several factors contribute to this conclusion:a) Solar energy is freeOnce you install a solar system, you can enjoy free energy as long as the Sun is up in the sky. It’s for everybody, you don’t have to pay for it. You can just enjoy its benefits. While fossil fuel energy is brought to you by different energy suppliers you have to pay serious money to, the sun’s energy is there for free.Yes, the cost of installing such technologies can prove to be a substantial investment, but in time, you will save a lot of money on energy. If you think long-term, the benefits are considerable.Fossil fuel energy is expensive, and you can see that on your monthly bills. It seems like every year energy prices increase and you have to pay more on the bills. It is obviously not convenient to continue like this. The cost efficiency balance of fossil fuel energy starts to lose its equilibrium in favor of the costs. Until when will you be able to continue paying expensive bills?Looking at it this way, abandoning fossil fuel energy in favor of a low-cost type of energy is common sense. Relying on solar energy, which is free, will lower electricity bills to an affordable level. In case you choose to produce all the energy your house needs using the power of the sun, you will save serious money on bills.b) Governmental incentivesAnother one of the economic benefits of solar energy is provided by the government. You can save money by using various financial incentives. Tax incentives, various credits and rebates encourage people to go green. Learn about the incentives available in your state, and the costs of installing solar panel systems will substantially lower.c) Low maintenance costsThe maintenance of a solar system is easy and cheap. After the initial investment in installing the solar system, the chances of spending money on it will be quite limited.d) Fast recuperation of the initial investmentAfter you install the solar energy system, you will recuperate your investment in a few years, and you will be able to enjoy its benefits sooner than you thought. When it comes to the long-term advantages of solar power, cost efficiency clearly differentiates this energy source from the rest.e) Net meteringIn case your system produces more energy than you need, you can sell it to your utility company. You can not only save money, but also make money with the help of your solar panels.f) DIY solutionsYou can reduce the initial investment with the help of a “Do It Yourself” kit. You can either learn to build solar panels by yourself, or just learn to install the solar panel. Enjoy the advantages of solar energy while learning something new and exciting.3. Energy independencea) Solar energy is self-sufficientThe perspective of energy independence is one of the most appealing reasons to choose this source of energy. Depending on another entity is always frustrating for a human being who likes to have full control over his life. Many times we have to endure power black-outs, accept increasing prices, or wait for somebody from the utility company to come to fix a problem of the energy system.Have you ever though of the possibility of becoming completely energy independent? Having a house that provides all the energy it needs by itself spares you the frustration of depending on various energy suppliers. Once your solar energy system is able to produce all the necessary energy, your house will become self-sufficient, your bills will lower, and you will have the certainty of a constantly available source of energy.b) Solar energy is available anywhereNo matter how remote the area where you live is, if the Sun shines, your house will enjoy solar energy. Among the many other advantages, the fact that it can provide energy wherever it is needed is an enormous benefit. It will be able to bring light to locations where power lines cannot be installed.A solar energy system can be easily installed in any location. Therefore, for people who would like to build vacation houses in the mountains or other remote areas, it provides a viable solution.4. FlexibilityProbably the most appealing benefits are its low costs and its environmentally friendly character. The economic benefits solar energy brings are undeniable. So is the fact that it helps you contribute to protecting the environment and becoming energy independent.Related to the idea of independence, there are other advantages that are worth mentioning. For example, solar energy systems are very flexible and adaptable to basically any situation. You can choose the solar technology that suits your needs best, install it where it fits, and invest in it depending on your budget. You can produce only a part of the energy you consume, or you can produce all the energy your house needs.Installing the system can be done at your own pace. If you cannot buy all the solar panels at once, you can start with smaller investments, and when you have the money, you can install some more panels. If you have a small house, you can install a small system, and so on. Solar energy is flexible, comfortable and convenient.
