Solar Energy Facts

This article will address some of the most interesting solar energy facts. Solar energy is definitely one of the most environmentally sound and desirable sources of power nowadays. Let's start off with the most apparent. Solar energy has actually been in existence since the dawn of time. It has always been utilized by plant, animal, and microbial life as the primary energy source. Plants, making use of photosynthesis, create nearly all of the food on this planet and are the base of the food chain. Furthermore the fossil fuels we depend on so heavily today are derived from plants and animals that existed a long time ago. Only in recent times have human beings been able to collect solar energy so that it has the potential to be used at any time of day or night, and in all weather, stored and transferred.

Every year, the earth's atmosphere receives 3.85 million exajoules of energy from our sun. This most likely doesn't mean much to you, but by comparison, the entire usage of electric power by all people young and old on this planet is only 56.7 exajoules per year. This means that in only a few hours, our planet receives more energy from the sun than people today consume in a whole year! Solar energy is an incredibly clean source of power simply because, in contrast to fossil fuels, using this kind of energy won't discharge carbon dioxide or other dangerous contaminants into the atmosphere. Furthermore solar energy is actually collected by just about every single form of life. You have most likely never seen a reptile collect wood to start a fire, but you almost certainly have seen one lying on a rock to soak up solar energy. Solar power is possibly the most environmentally sound energy option obtainable these days.

Chances are you may be curious about precisely what solar energy is capable of doing for our environment. Every year, humans consume 467 exajoules of energy through a few main power sources: burning coal, gasoline, and oil, together with ‘green' sources like wind, solar, and hydro energy. In the event that we could possibly capture just 10% of the sun's energy, we would be able to replace all of the fossil fuel sources and have sufficient space for growth. Without a doubt solar energy facts like this clearly show how much better solar power is for the environment and how big the potential is for solar energy growth.

Considering that you've looked over some of the most impressive solar energy facts and now have an understanding regarding what solar energy can certainly do for our planet, you would perhaps like to find out just exactly what solar energy is. Basically, solar energy is the heat and light energy given off by the sun. The sun continually releases enormous amounts of energy into our solar system. About 30% of the sun's energy that reaches the earth is immediately reflected back by the atmosphere, and another 20% is usually absorbed into the atmosphere. Having said that, nearly 50% of the energy gets to the earth's surface, where it fuels photosynthesis in plants, maintains hot tropical and warm temperate climates, maintains the temperature of the ocean, and generally speaking preserves life as we know it.. All of this is accomplished without creating any kind of pollution or destruction of natural resources.

Many people do not understand how solar energy functions on a technical level, and so they question what solar energy is going to provide to their households, businesses, and communities. During the last three decades, solar energy technology has developed at a rapid rate. Solar energy is collected at a few big power plants in the U.S., Spain, Australia, and in other nations, where it supplies energy directly to the power grid. This signifies that countless houses around the world already obtain electricity generated by the sun. One of the lesser known solar energy facts is that solar power may also be utilized on a much smaller scale. Solar panels on the roofs of homes and businesses, can generate a portion (or perhaps all) of the power these buildings need to have. On a still smaller scale, solar panels are employed in India and Indonesia to disinfect drinking water, and compact solar burners and ovens are employed to cook food in other areas of the globe . Solar energy might be used to fuel virtually any process you might picture, from large-scale electric power generation for towns and cities to boiling a single pot of water.

What makes just about all of these various uses possible is the construction of solar energy systems. You'll notice two primary forms of solar power technologies presently used today: solar thermal energy (STE) and photovoltaic (PV) energy. Solar thermal collectors merely harness the heat or thermal energy produced by the sun. This thermal energy is usually used to heat water which then can easily be stored and used for regular every day needs or piped for use in a household heating system. STE may be stored by warming or energizing a thermal mass that will be able to continue to radiate heat energy even when the sun isn't shining. Solar thermal collectors are much more efficient than photovoltaic collectors but on the other hand energy storage is definitely somewhat more cumbersome. Photovoltaic solar panel systems produce electricity whenever they are exposed to sunlight. The electric current can be utilized instantly as well as stored using batteries for later use. This can be one of the more significant solar energy facts whenever you are working with PV energy systems. Battery storage is extremely important since it means that it is feasible to hold solar power for use throughout the night as well as during gloomy or rainy periods.

Solar energy is a vital alternative energy source which will make it possible to take care of the environment. It can also help to reduce our dependency on fossil fuels. You may very well be asking yourself how big of an expense it is going to be for you to convert to solar power? Solar power is typically not as expensive as people think. A complete solar power system for a home may possibly cost you more than $30,000, having said that this doesn't mean you will be paying that total amount. For one, you can find quite a few types of incentive programs, including tax credits, rebates and grants, which often can help to reduce the cost of investing in solar panels by 30% or more . An alternative route you may wish to consider is a smaller sized solar energy system that merely supplements your home energy needs. A small system will definitely cost substantially less, while still cutting down your power bills, and it will definitely help make your home more environmentally sound. Today most electrical energy is produced using fossil fuels. So reducing your current use of electricity from your local power company by 50% is a substantial step in the direction of developing a sustainable power grid.

In this article, we have made an effort to supply you with a number of important and thought provoking solar energy facts. When you consider these facts, also consider how much importance you place on the condition of our environment and on mankind's ability to preserve it. In the event fossil fuels do not run out during the next 50 years, it is likely that their sustained use as our primary energy resource will cause environmental havoc. Investing in solar power now might not instantly save you money, but your monetary investment can certainly provide a healthier future for everybody under the sun.
