How Does Solar Energy Work

This article explains a few things about Solar Energy, and if you’re interested, then this is worth reading, because you can never tell what you don’t know.

Ever wondered how solar energy is converted into electricity? Well, this will give you an idea how it works.

First, solar panels are installed over a flat surface like the roof of your home. Once activated, it absorbs the sun?s rays since the panels are made of semi-conducting materials such as silicone.

Electrons are then knocked off loose from their atoms so it can produce electricity. This process by which light is converted into electricity is better known as the photovoltaic effect.

From there, you now have direct current electricity and when this enters an inverter, it is converted into 120 volt AC which is the electricity needed to power the home. Of course this is connected to the utility panel in the house so the lights and the appliances will work when these are switched on.

If you are not using that much electricity from the solar energy generated, it is stored in a battery so will be able to supply the house with power during a power outage or at night. Should the battery be full, the excess electricity is then exported to the utility grid if your system happens to be connected to it. When your solar energy runs out, utility supplied electricity kicks in.

The more authentic information about Solar Energy you know, the more likely people are to consider you a Solar Energy expert. Read on for even more Solar Energy facts that you can share.

The flow of electricity of solar energy is measured using a utility meter which spins backward and forward. It will go backward when you are producing more energy than you need and forward when you need additional power from the utility company. These two are only offset when you pay for the additional energy from the utility company. Any surplus is sod back to what is known as net metering.

A smaller version of this is used to power a water heater inside the home. Using the same principles, homeowners get to convert sunlight into heat to get warm water.

As you can see, transforming sunlight into solar energy is very easy. But why do countries like Germany and Japan use it more often than the US? The answer is because it is much cheaper for them to use this form of alternative energy compared to oil.

Also, although the US initiated this during the 1973 oil crisis, it is not as popular as it was back then because the government neither increased the budget in research for alternative forms of energy nor gave incentives so people will be encourage into doing that again.

Most state regulations also prohibit individuals from installing their own devices even if this is used to give you warm water. Chances are, you won?t even find anyone to do it so you will probably have to do it yourself. Just remember that if there is a problem with the plumbing, your insurance will not cover it. Should the state allow you to install such a system, you will not be entitled to the rebate.

Using solar cells is just one way to make the most out of solar energy. Your other option is passive solar energy which helps avoid heat loss so those inside will not feel too cold or too hot throughout the day. This is used by a lot of homeowners living in the southwest since they do not need that much insulation compared to homeowners who live in other parts of the US.

You can’t predict when knowing something extra about Solar Energy will come in handy. If you learned anything new about Solar Energy in this article, you should file the article where you can find it again.

An Overview on the Interesting Facts about Solar Energy

Would you like to find out what those-in-the-know have to say about Solar Energy? The information in the article below comes straight from well-informed experts with special knowledge about Solar Energy.

There are lots of interesting facts about solar energy. Educating yourself about this will prove to be beneficial in the long run. You can share the information to your loved ones. You can teach them of ways on how they can help to conserve the energy. You can also do your share to help this method to advance if you are a genius in the field. But if you are an ordinary citizen who only wants to enjoy, then feast on. But remember that you also have responsibilities to the environment that you must accomplish in order to do your part in the whole scheme of things.

The Facts that Matter
1. Solar radiation makes it possible for the energy coming from the sun to be used as power source and energy that can in turn be used for many purposes. The technology on this aspect is characterized in two ways. They can either be passive or active. This will depend on the methods that are used to get, convert and allocate sunlight.

What are active solar techniques? These utilize pumps, photovoltaic panels and fans to renovate sunlight into useful resources. These aim to increase the energy supply that is why these can also be referred as supply side technologies. The passive solar techniques, on the other hand, use only selected resources with constructive thermal properties, utilize the kind of spaces that can circulate air naturally and apply the position of buildings and structures towards the sun. These will lessen the need for other sources and can also be referred as the demand side technology.

2. Solar energy has influenced many factors that surround people. This can be referred in planning and designing buildings. This process can be rooted back at the early days of the architectural history. The Greeks and the Chinese first used such factor in building and constructing their architectural pieces and on their planning methods.

Once you begin to move beyond basic background information, you begin to realize that there’s more to Solar Energy than you may have first thought.

3. Solar energy is also being utilized by the agricultural sector because they rely heavily on its benefits in order to gain more harvest. They developed ways in order to plant the kind of crops that will grow according to the amount of sun that they will be getting for the season. This can also be used to dry the crops, pump water, brooding of chicks and to dry animal manures that can later be used as fertilizers.

4. On seasons like the Little Ice Age, fruit walls were used by French and Chinese farmers to be able to collect and store solar energy to help them keep the plants warm and to speedy up the process of ripening of fruits. These walls serve as the thermal masses. The fruit walls that were first developed were perpendicular to the ground and faced the south direction. Over time, innovations were done and slopping walls were used to gain more advantage from the sun.

5. To convert the solar light into heat, people have developed greenhouses. These enable the production and cultivation of specialty crops all year round. Such innovation made it possible for crops to be produced in untimely seasons and in places where you think that those plants won?t grow.

And these are only some of the interesting facts about solar energy. These give you a good peek at how wonderful nature is and how people have developed ways to use it to advance in many aspects of their lives.

Countries on the helm of solar energy technology

The US is not a leading user of solar energy for a very obvious reason: they can still afford to buy fossil fuels from the international market. In other countries the oil prices are ten times higher in the US and sometimes going for the alternative is a lot better in the long run. Today, more and more countries are looking at solar energy as a primary source of power. There are several countries which can be considered as at the helm of solar energy technology.

The number one use of solar energy is Germany. It captures almost 50% of the world market of photovoltaic cells. Nowhere else in the world can you find the most number of households with solar panels installed on their roof tops. Germany has this Renewable Energies Laws (EEG) which passed in 2000. The law certainly helped Germans feel the need to go renewable.

According to statistics, Germans invested nearly US$5 billion in solar photovoltaic systems and have contributed considerable in the growth of the solar energy market. Although most of the things that we see are solar panels, it doesn?t mean that Germany?s solar industry is not limited to the production of photovoltaic cells for electricity. Other notable usage in Germany includes solar panels for home water heating system. Some news indicate that the German solar hot water market earns fU.S.$1.5 billion per year.

The ?solar park? in Arnstein, Bavaria, Germany is one of the biggest photovoltaic plants in the world. It became operational in 2006 and with more than 1,400 PV solar panels, it can produce 12 megawatts of energy.

The next biggest country in terms of usage of solar energy is Spain. The solar energy usage in the country, more specifically the photovoltaic cells usage, has a world market share of 27%. Spain has no sign of slowing down its aggressive and pro-active approach in solar energy. Solar fields are being constructed one of the latest ones is the 60 MW solar field in Olmedilla de Alarcón, near Cuenca.

The more authentic information about Solar Energy you know, the more likely people are to consider you a Solar Energy expert. Read on for even more Solar Energy facts that you can share.

There are other big solar plants in Spain and these include the solar park 12 miles outside of Salamanca, Salamanca, Spain which have 70,000 PV panels divided into three 36-hectare arrays. The arrays produce an output is 13.8 megawatts and has been powering roughly 5,000 homes since it opened in 2007.

And the rest of the world follow Germany and Spain. Japan and the US still have a market share in the photovoltaic world market. The two countries both have an 8% market share, a far cry from Germany and Spain. Nevertheless, it is quite important that countries continue to improve their status in the world solar market.

Other notable country that uses solar power includes Alegeria, Australia, Italy, and Portugal. Aside from the rich European countries, people in Israel and India are realizing the importance of having alternative sources of energy.

These are the countries on the helm of solar energy technology. But, other countries are slowly catching up. The government of Israel, for example, required all residential buildings to install solar water heating systems in the early 90s. Today, business establishments like hotels and office buildings are trying to use solar power as an alternative from using fossil fuels whose prices continue to soar in the world market.

India is facing a similar energy crisis and they are also looking at solar energy to get them through it.

What is Solar Energy

Do you ever feel like you know just enough about Solar Energy to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from Solar Energy experts.

Solar energy is a form of renewable energy as it utilizes the radiant energy coming from the sun. This is done by converting sunlight into electricity using solar cells.

Solar cells or photovoltaics were invented in the 1880?s by Charles Fritts. Although it did not convert a lot of sunlight into electricity at the time, this started a revolution that continued on to the 20th century. The greatest example is perhaps the Vanguard 1 which was a satellite fitted with solar cells that enabled it to transmit back to earth after its chemical battery was exhausted.

It success prompted NASA and its Russian counterpart to the same with other satellites including Telstar which continues to serve as the backbone of the telecommunications structure today.

The most significant event that stimulated the demand for solar energy was the 1973 oil crisis. Early on, power companies would charge the consumer a hundred dollars per watt. In the 1980?s, it became only $7 per watt. Unfortunately, the lack of government funding did not sustain its growth so the growth of solar energy was only 15% annually from 1984 to 1996.

There have been a decline in the demand for solar energy in the US but this increased in Japan and Germany. From 31.2 megawatts of power in 1994, this increased to 318 megawatts in 1999 and world wide production growth increased by 30% towards the end of the 20th century.

Next to these two countries, Spain is the third largest user of solar energy followed by France, Italy and South Korea.

Think about what you’ve read so far. Does it reinforce what you already know about Solar Energy? Or was there something completely new? What about the remaining paragraphs?

There are three basic approaches to get the most out of solar energy. It is namely passive, active and solar photovoltaic systems.

1. In passive, it has to do a lot with the building design. This will enable the building to avoid heat loss so people inside will feel a great degree of comfort with the help of controlled ventilation and day lighting. Homes that apply this will greatly reduce their heating requirements by as much as 80% with minimal cost.

2. Active solar heating is used to convert sunlight into heat which provides space or water heating. Used extensively in Europe, getting the right size will cover 50% to 60% of your hot water heating requirements.

3. Lastly is photovoltaic which converts solar radiation into electricity. This is done by installing solar cells in the ground and the greater the intensity of the light, the greater the flow of electricity. These are available in different sizes and some are installed in consumer devices like calculators and watches.

Some vehicles are now powered using solar energy. Cars although not yet produced commercially compete in the World Solar Challenge which invites competitors from around the world to compete in this annual event in Australia. There are also unmanned aerial vehicles and balloons. To date, solar energy has only been successful in passenger boats.

Many of us take the sun for granted and if we are really serious about preserving the environment and reducing our demand for oil, solar energy is just one of the options we have on the table. We have to lobby and convince our government leaders to do more because it is the cheapest means of providing our home with electricity compared to rechargeable batteries, kerosene or candles.

Take time to consider the points presented above. What you learn may help you overcome your hesitation to take action.

The Pros and Cons of Solar Energy

Solar energy is one of the best forms of renewable energy. But why don?t we rely on it so much compared to other countries? The answer is simply that there are pros and cons with using this form of alternative energy.

The pros of using solar energy is that the system is easy to install, there are no energy costs once it is set up, there are no emissions like air pollutants or greenhouse gas and the sun is widely available.

A solar energy system is composed of the solar panels, the inverter, battery, charge controller, wires and support structure. For you to produce a kilowatt of power, you will need 10 to 12 solar panels that will occupy an area of 100 square feet. If you are worried that this will cause damage to your roof, don?t because it is made of light weight materials.

When you call a contractor, it will usually take a day or two to install and cost around $10,000. Not that many people will have cash on hand to pay for it so they can avail of a home equity loan to pay for it.

If you use a kilowatt of solar energy, you can save 170 lbs. of coal from being burned, about 300lbs of carbon dioxide from being released into the atmosphere or 105 gallons of water that most homeowners use up every month.

The cons are solar cells are expensive, the rays can only be collected during the day time, the weather and where you are located will play a factor in how much sunlight you can get and you will need a big area to collect the power.

Once you begin to move beyond basic background information, you begin to realize that there’s more to Solar Energy than you may have first thought.

But some experts believe that price of these cells and its ability to collect power will improve in the future.

Right now, a kilowatt of solar energy can only produce 1,600 kilowatts of hours per year in sunny climate. That means you will receive 5.5 hours of electricity per day. If you produce about 750 kilowatts of power, you will only get 2.5 hours of power per day.

Solar panels come in various colors and usually have a 5 year warranty. Since manufacturers are aware that solar energy can only work when the sun is out, they have installed batteries so you get more than 5 hours of power even during cloudy days and nights. This is because the batteries are designed to absorb, insulate, transmit and reflect rays coming from the sun.

But solar energy can be applied to other things and not just powering our homes. It can be used to power small devices like calculators to bigger things like planes, satellites and cars. Since these are easy to maintain, you don?t have to worry about anything.

Now that you know the pros and cons of solar energy, the question remains, should people get into it or not? If you look at it, the answer is definitely yes because is a renewable source of energy that does not cause any harm to the environment. It will also greatly reduce our need for oil which has become a very hot issue especially when the price per barrel went out to more than a hundred dollars early on this year.

People should take this seriously especially when this is not a renewable source of energy.

Wind power vs Solar energy, an even match?

The following paragraphs summarize the work of Solar Energy experts who are completely familiar with all the aspects of Solar Energy. Heed their advice to avoid any Solar Energy surprises.

Today in center stage is a battle for the ages. On the right corner, packing a hurricane punch yet is known to move softly as a breeze is wind power. On the left corner, with a scorching hot aura, moves in a speed of light, is solar energy. Wind power versus solar energy, which one is going to be declared the champion of the alternative energy movement?! Let?s get ready to rumble!

Or something like that. I apologize for that intro but I just can?t help. I figured that if I was going to match one alternative energy resource against the other, then I?ll make some extravagant introduction. Just imagine the drum rolls.

Actually, there is an existing debate among environmentalists and even scientists on which energy resource should be developed first given their advantages and drawbacks. Staying away from the personal biases, numerous studies have shown that overall, wind power is more cost effective than harnessing the sun?s energy. Let?s see the reasons behind that conclusion.

Harnessing the sun?s energy can be done by a number of ways. But probably the simplest way which can be applied in a small home is by using photovoltaic cells or PV or solar cells. What happens is that sunlight hit the surface of a photovoltaic (PV) panel which responds by creating free electrons which is channeled to generate an electric current.

Wind power on the other hand utilizes a propeller and a shaft system which has a magnet wrapped by a coil of wire inside. As the wind turns the propeller and the magnet inside, the electrons in the wire are forced to move along the wire producing an electrical current.

If you find yourself confused by what you’ve read to this point, don’t despair. Everything should be crystal clear by the time you finish.

Both ways are quite simple but the complexities now lies on the costs of producing the necessary equipment especially the mechanisms that will maximize the power output. When costs of production of photovoltaic cells and wind turbine are compared, the latter is much cheaper to produce. Although, manufacturers of photovoltaic cells stress that as the demand on PV cells increase, the costs of production decreases. So its just a matter of time before PV cells become price competitive.

Other problems include the logistics of placing the equipment. A solar panel requires quite a large space plus, your location on the globe will affect the amount of sunlight you receive and consequently the amount of power you produce. The further away from the equator you are, the less amount of sunlight you can harness. Also, on the average, the PV cells have a 15-20% efficiency rate.

The problem with wind power on the other hand is that not all areas will have winds favorable for a turbine. And if you do locate a place where winds are strong and the turbine can be maximized, you?ll find that the area (more often than not) is inhabited by various species of birds. You don?t want to kill birds with your turbine, do you?

Now going back to our wind power vs. solar energy match-up, indeed we do have to agree that wind power is more cost efficient. However, both alternative energy resource will play a big role in our future.

It is, therefore, in my humble opinion that we both develop the two technologies simultaneously for each one has their advantages and disadvantages and each one can be properly utilized for specific areas.

How to Conserve Solar Energy through Your Little Ways

As an ordinary person who lives according to what the day brings, have you ever thought about how to conserve solar energy? Do you even care? You may think you are an ordinary worker, or a simple wife or mother. Should you even care about such things? The answer is yes.

You must bear in mind that you are part of a whole spectrum of nature. Whatever you do will affect all the things around you. Everything must be conserved, including solar energy. Here are some suggestions to throw in your little efforts to achieve this goal.

1. Plant trees. Nature works wonders. Every element around us affects everything else. By planting trees, you will be able to maximize the energy coming from the sun. This will be directed to help the plants grow and produce harvests. With healthy plants and trees rooted to the soil, the soil will be firm. This will be able to hold its structure even in times of natural disasters.

2. Limit your use of the energy coming from the sun. With today?s innovations, there are lots of things that are being developed to use solar energy as a power source. The source may be free. But to be able to turn it to such power source, there are things that are utilized for this reason. If you will abuse the use of such technology, the crash of the materials used to put this up will be fast. This will take a toll on you especially if you rely a lot on this advancement.

Those of you not familiar with the latest on Solar Energy now have at least a basic understanding. But there’s more to come.

3. Teach kids about the importance of solar energy. You can gain knowledge through research and through your everyday interaction with other people about this thing called the solar energy. You must tell your kids about its importance, they must be educated about it at an early age. They are the future of the nation. What you teach them now will be instilled to them until they grow old. At such a young age, they must know about how they can contribute to conserve energy.

4. Take good care of nature. This is the most important thing that you can do to help advance such cause. The sun can cause damage to people and nature if people won?t do the necessary steps to care for nature in the first place. There are lots of things that you get from the environment. It wouldn?t hurt to look back every now and then and see what you can do to give back to what it has already given to you.

The idea here is that everything in this life must be conserved. You cannot abuse the power that you posses to gain so much without even thinking how your actions affect the world around you. It is all right to go with the flow of the continuing advancement of the technology.

Look at the options available to you nowadays with regards to solar energy. This can be used to power homes and vehicles. This can give light, heat water and cook your food. This can give you satellite television and phones for supreme entertainment and communications enjoyment. This can give you luxuries like spas and warm water at pools.

You must learn everything on how to conserve solar energy so that you can do your part in making sure that such resource will be available as long as you live.

Using solar energy goes way back

Recollecting the history of solar energy brings us back to the 1970s energy crisis and oil embargo which caused long lines in gasoline stations, high gasoline prices, and even caused panic among consumers and investors alike in the United States. Knowledge about oil being a non-renewable resource has been around since the 1800s. But it was only during and after the 70s energy crisis that people really began to realize the consequences of depending too much on an already depleting energy resource.

However, utilizing the sun?s energy is not really a recent development. It has been used by ancient civilizations for warmth, for food and crop preparations and various agricultural purposes. What?s new are the technologies involved in harnessing this energy and utilizing it for man?s daily use.

The technology began in the 1830?s when Edmund Becquerel made public his studies on how solar light can be harnessed into usable energy. However, nobody followed up on this idea nor explore any practical use. The next breakthrough on solar power came after thirty years Becquerel published his works.

In 1860s, the French Monarch commissioned Augusted Mouchout to find other sources of energy. And Mouchout looked up in the sky for inspiration. His series of solar powered contractions were quite impressive back then. His inventions included a motor that run on solar energy, a steam engine that uses the sun?s light, and an ice maker that fully rely on solar power.

It’s really a good idea to probe a little deeper into the subject of Solar Energy. What you learn may give you the confidence you need to venture into new areas.

After Mouchout, there were several other notable achievements in the line of solar power. Among these is the works of William Adams in the 1870s which utilized mirrors to channel the power of the sun to make a steam engine run. Adams? power tower design concept is still in use today. Another notable work is by Charles Fritz in the early 1880s. His studies were attuned on turning sunlight into electricity, which he later accomplished.

But one of the most significant development in modern solar energy occurred in the 1950s. Early in the decade, R.S. Ohl discovered that sunlight produces large numbers of free electrons when it strikes silicon. Then in the mid-1950s Gerald Pearson, Calvin Fuller, and Daryl Chaplin was able to capture those free electrons and convert them in electricity. Today, silicon cells are used to make solar cells and solar panels for harnessing the sun?s energy.

Immediately these solar cells were made into good use and the first among to use them was the field of space aeronautics. These silicon based solar cells were used to power satellites that orbit the earth. The satellite Vanguard I was the first one launched out to space which rely on solar cells for power. More satellites followed.

Nowadays, more and more research and studies are being conducted on how best to utilize the sun?s energy. Especially today where it is said that about 30-50 years from the now, the world oil reserves will be totally depleted. Thus, the search for alternative sources of energy continuous. The sun is expected to die out in a couple of thousand of years, it?s to long to worry about and man can have all the sun?s energy until that day.

The challenge today is creating solar energy power in more efficient and cost effective e way. Admittedly, the costs of those photo cells are not that cheap to be accessible by most of the ordinary consumers. The movement today in the science and technology committee is to be able to provide cheap alternative source of energy.

There’s no doubt that the topic of Solar Energy can be fascinating. If you still have unanswered questions about Solar Energy, you may find what you’re looking for in the next article.

Solar Energy – How Does It Benefit the Agricultural Sector

If you’re seriously interested in knowing about Solar Energy, you need to think beyond the basics. This informative article takes a closer look at things you need to know about Solar Energy.

What is solar energy? To put it simply, this is the energy coming from the sun. The heat and light that the sun provides are essential to life. Can you even imagine life without the sun? It will not be normal and there are lots of things and experiences that people can no longer indulge into if ever that will be the case.

Everybody relies on the sun for its benefits. Did you know that the earth gets 174 petawatts of insolation or the incoming radiation from the sun? This happens at the upper part of the atmosphere. Almost 30% gets reflected back to the space. The rest of the percentage is being absorbed by the clouds, land masses and oceans.

The Agricultural Sector
If you can think of one industry that won?t survive without the energy coming from the sun, what will be the first thing on your mind? There may be many sectors that must rely on the sun?s benefits. But the agricultural and horticulture industry will not thrive without it. They have no other options. If the sun will be gone, these sectors will die.

The sun is need by the agricultural and horticulture departments to be able to grow their produce. The latter is needed by people as well as animals. These sectors? productivity will depend on the amount of energy that they are getting from the sun. It must be balanced in all ways. It can never too little. And it must also not be so much.

If it is too little, the plans may not be able to grow accordingly. The farmers won?t achieve the required harvests in order to feed the population. And if it is too much, this will damage the crops. This will also cause bad effects on people?s health. But if the latter is the case, people can think of ways in order to achieve the needed produce by manually trying to reduce the amount of heat that can be directed on the plants. But if the situation becomes unbearable, it might lead to drought and deaths.

Knowledge can give you a real advantage. To make sure you’re fully informed about Solar Energy, keep reading.

Farmers must know when the sun will be up, when sunny days will be long and factors like that so that they can settle for what kinds of plants they must plant to survive the kind of weather condition. Here are only some of the things that they resort to in order to optimize the full benefits of the energy coming from the sun.

? Timed planting cycles
? Different heights of plants in between rows
? Tailored row orientation
? Mixing different varieties of crops to improve the yields

Do you ever wonder what farmers did in times like the Little Ice Age? It is said that English and French farmers resorted to fruit walls. These fruit walls help in maximizing the collection of the energy from the sun. These serve as the thermal masses. These walls help in keeping the plants warm to speed up the process of growing and ripening of produce.

The sun?s energy is also being utilized in these sectors in vital activities such as drying the crops, pumping of water, drying animals? manure, brooding of chicks and a lot more.

It is hard to imagine the agriculture and horticulture sectors to survive without the solar energy. If there are anybody who knows the importance of the sun, these people are the first in line.

The History of Solar Energy

Solar energy is for everyone simply because the sun shines in every corner of the planet. In fact, the history of solar energy can be traced back to the Greeks that were then passed on to the Romans which marked the first people to ever use the passive solar design.

Passive solar design is a way to warm the home based on the dwelling?s design. They may not have had glass windows back then but their architecture made it possible for the people to use the sun?s rays to light and heat indoor spaces. As a result, there was no need to burn food that often which was in short supply.

In 1861, Auguste Mouchout invented the first active solar motor. Unfortunately, its expensive price made it impossible to produce commercially. Less than 20 years later, Charles Fritts invented solar cells which will later on be used to power homes, heaters, satellites and other devices today.

Since what he invented was very primitive, other people experimented on solar energy. One such person was Albert Einstein who won the Nobel Prize for physics in his research on the photoelectric effect which is a phenomenon associated with the generation of electricity through solar cells.

In 1953, Bell Laboratories which we know today as AT&T labs developed the first silicon solar cell capable of generating a measurable electric current. Three years later, solar cells ran $300 per watt. With the Cold War and the Space Race on, this was used to power satellites and crafts.

But the biggest event in the development of sola energy occurred during the oil crisis of 1973. This prompted the US government to invest heavily in the solar electric cell that was developed by Bell Laboratories 20 years ago.

So far, we’ve uncovered some interesting facts about Solar Energy. You may decide that the following information is even more interesting.

By the 1990?s, research towards solar energy came to a standstill as the price of oil dropped in the world market. Funds were diverted elsewhere and the United States which was probably the leader in this form of alternative energy was soon surpassed by other nations mainly Germany and Japan.

In 2002 for example, Japan had installed 25,000 solar panels on rooftops. Because of that, the price of solar panels went down as the demand for it was on the rise. To date, solar energy is growing at a modest 30% per year.

Although there have been improvements in solar energy, its fundamentals are still the same. The sun?s rays are collected and then converted into electricity. Aside from powering homes or office buildings, the technology has been used to power aircraft, cars and boats.

Unfortunately, none of these have been made available yet for public use. We still rely heavily on oil for electricity, gasoline for our cars, fuel for planes and ships.

In fact, the US is one of the biggest oil users in the world. To prove a point, the department of Defense consumes 395,000 barrels per day because of the wars being fought right now in Afghanistan and Iraq which is almost the fuel consumption of an entire country like Greece.

This has to change because our oil reserves are almost depleted and many experts believe that global supply for these non-renewable resources will be gone before the end of the century. We have to do our share to push for renewable energy and one of them happens to be solar energy.
