This article is going to cover some of the most fascinating solar energy facts. Solar energy is typically among the most ecologically friendly and desirable sources of energy these days. Let's start out with the most obvious. Solar energy has actually been in existence since the beginning of time. It has been used by plant, animal, and microbial life as the primary energy source. Plants, employing photosynthesis, generate virtually all of the food on earth and are the base of the food chain. Additionally the fossil fuels we depend on so heavily today were derived from plants and animals that lived a long time ago. Only just recently have human beings been able to capture solar energy in a form that has the potential to be used at any time of day or night, and in any weather, stored and transferred.

Each year, the earth's atmosphere absorbs 3.85 million exajoules of energy from the sun. This may not mean much to you, however in comparison, the total usage of electric power by all human beings around the world is only 56.7 exajoules per year. This means that in only a few hours, the earth absorbs more energy from the sun ...
... than people consume in a whole year! Solar energy is a very clean source of power due to the fact, in contrast to fossil fuels, making use of this kind of energy doesn't discharge carbon dioxide or various other dangerous toxins into the atmosphere. Also solar energy can be collected by virtually every single form of life. You've most likely never observed a wild animal collect wood to make a fire, but you almost certainly have observed one lying on a rock in order to absorb solar energy. Solar energy is almost certainly the most environmentally sound energy option attainable today.

You may be curious about just what solar power can do for our natural environment. On a yearly basis, humans consume 467 exajoules of energy by utilizing several principal power sources: burning coal, gasoline, and oil, as well as ‘green' sources like wind, solar, and hydro energy. If 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. Undeniably solar energy facts like this exhibit just how much better solar energy is for the environment and how great the potential is for solar energy progress.

Considering that you've reviewed a few of the most remarkable solar energy facts and now have a better perception about what solar energy can potentially do for the earth, you'd probably want to learn specifically what solar energy is. Quite simply, solar energy is the heat and light energy given off by the sun. Each day the sun emits immense quantities of energy into our solar system. About 30% of the sun's energy that reaches the earth is immediately deflected by the atmosphere, and an additional 20% is typically absorbed into the atmosphere. Nevertheless, about 50% of the energy gets to the earth's surface, where it fuels photosynthesis in plants, sustains both hot tropical and warm temperate climates, sustains the temperature of the ocean, and generally speaking preserves life as we know it.. Every bit of this is achieved without any type of pollution or destruction of precious natural resources.

Many people today don't recognize how solar energy functions on the technical level, and so they wonder precisely what solar energy is going to add to their homes, businesses, and communities. In the last three decades, solar energy technology has been developed at a accelerated rate. Solar energy is gathered at a number of big power plants in the U.S., Spain, Australia, and in various other nations, where it provides power directly to the power grid. This means that a large number of homes around the planet currently obtain electricity provided by the sun. Among the lesser known solar energy facts is that solar power may also be used on a much smaller scale. Solar panels on the tops of households and businesses, can certainly produce a portion (or perhaps all) of the power these buildings need. On an even smaller scale, solar panel systems are employed in India and Indonesia to disinfect water, and compact solar burners and ovens are utilized in order to cook food in other parts of the world . Solar power may possibly be utilized to fuel practically any process you can think of, from large-scale electricity generation for metropolitan areas to boiling an individual pot of water.

What makes just about all of these various uses achievable is the development of solar energy systems. You'll notice two standard kinds of solar power technology presently used at this time: solar thermal energy (STE) and photovoltaic (PV) energy. Solar thermal collectors basically just harness the heat or thermal energy produced by the sun. This thermal energy is usually utilized to heat water which in turn can easily be stored and used for regular domestic needs or piped to a household heating system. STE is able to be stored by warming or energizing a thermal mass that will continue to radiate heat energy when the sun isn't shining. Solar thermal collectors are actually considerably more efficient in comparison with photovoltaic collectors but on the other hand energy storage is definitely a little more cumbersome. Photovoltaic solar panel systems make electricity whenever they are exposed to sunlight. The resulting electric current may easily be used immediately or alternatively stored using batteries for future use. This can be one of the more significant solar energy facts when working with PV energy systems. Battery storage is exceptionally significant since it means it is feasible to store solar power for use at night or during cloudy or rainy days.

Solar energy is an important alternative energy source which can make it possible to protect the environment. It will also help to minimize our reliance on fossil fuels. You may very well be asking yourself just how large of an expense it will be for you to switch to solar power? Solar power is typically not as pricey as most people believe. A full solar energy system for a house may cost you more than $30,000, however this does not really mean you'll end up paying that whole amount. To start off, there are actually a lot of different incentive plans, including tax credits, rebates and grants, that can decrease the price of investing in solar panels by 30% or more . An alternative option you might wish to give some thought to is a smaller solar energy system that just supplements your home energy needs. A small system will definitely cost substantially less, while still lowering your energy bills, and it will certainly help make your house a lot more environmentally sound. Currently most electrical energy is still generated using fossil fuels. So cutting down your current use of electricity coming from the area power company by 50% is definitely a significant step towards developing a sustainable power grid.

In this article, we've made an effort to supply you with a number of interesting and thought provoking solar energy facts. When you contemplate these facts, also think about just how much value you put on the quality of our environment and on humanity's ability to help preserve it. No matter if fossil fuels do not run out during the next 50 years, it's likely that their ongoing use as our principal energy resource is likely to cause environmental havoc. Investing in solar power now will probably not immediately save you money, but your monetary investment can certainly provide a more desirable future for everyone under the sun.
