PostHeaderIcon Countries on the helm of solar energy technology

So what is Solar Energy really all about? The following report includes some fascinating information about Solar Energy–info you can use, not just the old stuff they used to tell you.

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.

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.

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.

This article’s coverage of the information is as complete as it can be today. But you should always leave open the possibility that future research could uncover new facts.

PostHeaderIcon Facts about Solar Energy – Some Things to Ponder and Why

When you’re learning about something new, it’s easy to feel overwhelmed by the sheer amount of relevant information available. This informative article should help you focus on the central points.

What are the facts about solar energy that you know? It is given that this comes from the sun. This was developed by people in order to take advantage and benefit from everything that the sun can provide. You can also easily guess the goals of these people why they opt to develop such technology. For one, they want to make lives easier to live. Second, they want to find other resources that people can use in their everyday lives. Maybe they also want to profit from the experience because if this will all be successful, people, businesses and industries will gain a lot from what is being developed.

During the first years of its introduction, people deem that this technological advancement can only be used by wealthy people. It used to cater mostly for the can afford types of individuals. What if it can heat pool and can run spas? Why should an ordinary John Doe care when he couldn’t find time to have a good rest because times are hard?

But the evolution of the solar energy is just starting. Nowadays, the benefits can be felt even by ordinary citizens. Researchers keep thinking of ways to arrive at this state. And this is proving to be good for everybody’s sake.

1. The scientists developed solar panels that can power up homes. They made this available not only for the rich and famous, but they sold the idea to governments. The latter used the innovation to bring electricity to people in their countries who still haven’t experienced to live in the comfort of having this kind of power source. As a result, many people experience how it is like to have lights. They have also resorted to businesses that can be aided by such technology. The maintenance is still on-going while the technology is still being pursued. But the fact remains that this has been made available even for the ordinary John Doe.

Now that we’ve covered those aspects of Solar Energy, let’s turn to some of the other factors that need to be considered.

2. Aside from electricity, solar energy can be used to heat water and cook food. Life is really becoming easier as people find ways to achieve such state. While the developments are still under way, people are finding ways to make such resource available for everybody. Different organizations and government agencies help in making this product affordable for everyone no matter what your status in life is.

As time passes by, people will be able to develop more and more gadgets and tools to make lives easier. There will come a time when almost everybody can benefit from this. The first notion that the solar energy is only for the wealthy will cease to be remembered.

The responsibility now lies on to people’s hands to take care of nature. They must give back to nature for everything that they have also gotten in the process. Technological advancements can be better achieved if people will consider how these can affect the natural habitat in general. It is okay to get what people want and what people need. But this must always be done with precaution and by thinking of the effects that these will have on everything.

It is fun to learn some facts about solar energy every once in a while. These will excite you about the process. But more so, these must open your eyes to the whole scheme of nature and how important it is to take care of your surroundings to be able to benefit more in the long run.

PostHeaderIcon Solar energy simplified

The sun shines, we collect the sunlight, we convert the sunlight into usable forms, and we enjoy the benefits. You can’t get any simpler than that. But okay, I know you need more explanations. You’ve been looking all over the web for information and you need, no you deserve, more than just a single sentence. The following would be my attempt in simplifying the concept of solar energy and I just hope you get something out of it.

The sun produces huge amounts of energy. But what the earth gets is a pretty small share of that energy. However, even if we get only a miniscule amount, the energy we receive from the sun is more than enough for our needs. Believe it or not, a day’s worth of sunlight when harnessed properly can power a big country like the US for more than a year.

So if that’s how much energy we can get from the sun, why do we rely too much on fossil fuels which will disappear in 40 to 50 years time? The main problem is that the sun shines all throughout the world. That energy is so spread out that harnessing it is really a challenge. But still, there are other factors at work here, political, economical, and even cultural in nature which contributes to the slow progress of solar technologies. But that will need a whole chapter, nay, a whole book to discuss so let’s leave that alone for a moment.

There are various ways how we harness sunlight and the specific way may depend on how we plan to use that energy. But we can divide the usage into two general concepts, converting solar power into heat and the other one is converting it into electricity.

Using solar power to heat homes is a pretty good example of the first category. There are two ways that can be used, the first one relies on the positioning of the house’s windows and the second one involves the use of some mechanical devices to distribute the heat throughout the house.

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

Solar water heaters are also now available. What you do is provide a solar collector where the heat from the sun is trapped and collected. That heat is then transferred to the after that goes out of your faucets and showers.

Converting solar power into electricity, however, needs a little bit more explanation. There are basically two ways we can get electricity out of solar power. The first one involves the use of photovoltaic cells and the second one is using various solar thermal systems.

Photovoltaic cells are more commonly known as solar cells. These cells are made from silicon wafers and phosphorous. When sunlight strikes the surface of the silicon wafers, free electrons are produced. The electrons are then harnessed via attaching a wire to the cells. As the electrons leave the cells and pass through the wire, an electronic current is produced.

One major flaw of the photovoltaic cells is that they can be quite expensive plus they only convert a small amount of sunlight. Hopefully these cells can be cheaper, more efficient and more suitable to the needs of consumers in the future.

The great thing about solar energy is that it does not produce any kinds of pollution unlike fossil fuels which spit out substantive amounts of pollutants in the air and even in the water. Plus the sun is pretty much in good health ad it is still very far from dying. We can utilize more than enough energy from the sun that will last us for a lifetime.

The day will come when you can use something you read about here to have a beneficial impact. Then you’ll be glad you took the time to learn more about Solar Energy.

PostHeaderIcon Things You Should Know Before Investing in Solar Energy

This interesting article addresses some of the key issues regarding Solar Energy. A careful reading of this material could make a big difference in how you think about Solar Energy.

There is no doubt that there are a lot of benefits in using solar energy. Aside from protecting the environment, you get to save a great deal of money. But before you switch to solar energy, here are a few things you should consider.

First, is your roof right for solar power? Most solar power systems can be installed as long as the roof is flat and made of material such as bitumen, composite shingle, cement tile, metal or tar and gravel. If this is how your roof is positioned, then there shouldn’t be any problems.

The solar panels will be installed parallel to the roof surface. If you are concerned that the weight could be too heavy for your roof, don’t be since this is very light and quite rare that you have to do some structural work before installing the system.

When you are looking for a contractor, find out how much it will cost to install the system. You should compare these first before you decide in picking the best one. But you should know right now that installing solar powered cells are a bit expensive. There are also no financing programs you can avail of. Your best bet if you don’t have enough money is to apply for a home equity loan.

If you are planning to install this in a commercial establishment, the various loans you can avail of include the capital equipment loan, equipment secured loan, property secured loan or the SAFE-BIDCO energy efficiency loan.

The best time to learn about Solar Energy is before you’re in the thick of things. Wise readers will keep reading to earn some valuable Solar Energy experience while it’s still free.

Non-profit organizations may also avail of special loans for solar energy and the best one is through third party financing. In this case, the non-profit organization and the contractor will purchase the system and make use of the tax credits. The third party will then pass on the charges for the produced power to the non-profit and after the system has depreciated, this is sold to the non-profit at a discount.

The end result is that you pay for less than what you are currently paying for because it is maintenance free.

In fact, people are encouraged to borrow money to pay for solar energy. This is because you borrow money at a fixed rate and in return recouped your investment of about 7-11% annually as the utility rates increase so you pay less for it every month. This makes investing in solar energy very similar to other investments such as bonds, property and stock.

Will installing a solar system have any effect on your property? The answer is yes. In fact, it will increase the resale value of your property without having to pay much more in terms of property taxes. If you have a lot of space to spare, you may even be able to zero out your electric bill as long as the sun comes out so you can convert sunlight into electricity.

Aside from increasing the properly value, you will also be able to avail of tax credits from the government.

Solar energy can power your home in the same way you get electricity from the grid. You won’t be able to use it when there is a power outage or when the sun is shining but fortunately, this doesn’t happen daily so it is still an alternative form of energy worth considering.

PostHeaderIcon The Future of Solar Energy – How It Looks and How It Affects Nature

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.

The future of solar energy lies on the indigenous hands of people who never tire out from thinking of ways in order to make life easier to live. With the advancement in the technology, the boom of the Internet age and a lot of other things, there will come a time when people will turn their backs on whatever is conventional. This can be good and bad in many ways, depending on who is looking at it and from what perspective.

But people’s quest for the advancement and development of everything that surrounds them provides lots of negative effects as well. Here are only some.

1. Sometimes, people neglect the environment and how to properly take care of it for the mere fact that they are greedy to get their ideas done no matter what the consequences to the nature will be. Such advancements create harmful effects in the whole state and balance of nature. How many times have you heard about forest denudation or grave floods that kill people? All these occurrences can also be rooted to the activities of men that suffice for their own good without so much consideration for their natural habitat and the nature.

2. With the continuing advancement of everything that surrounds people, the generational gap becomes wider and wider. Old folks will fight for the benefits of the conventional tools and mediums. The newer generations cannot afford to sit on those old ways to do things. They are a slave to the continuing technological developments.

It is okay to initiate change. It is good to find better ways to do things. But people must be cautious in achieving this. They must think about everything around them before they even start on their venture to newer and better ways to achieve greatness.

You can see that there’s practical value in learning more about Solar Energy. Can you think of ways to apply what’s been covered so far?

The Innovations

As of today, solar energy is one of the best options that people have with regards to alternative power sources. This has already evolved. There was a time when you can only avail such power source when the sun is present and that is during daytime. With the genius of the people behind the development of this resource, they were able to create green gas that can produce electricity. This is done by splitting water properties into hydrogen and oxygen. Both gasses will then be grouped into a cell that will be the electricity source.

The same geniuses estimated that the entire planet can rely to an hour of sunlight for its one year electricity consumption. Solar cells have been developed to produce electricity from the energy coming from the sun. The panels for such technology can also be used to heat water and cook food. There are now the solar heating, solar cookers and solar furnaces as add-ons to this innovative venture.

There are now hydrogen based cars. These are fueled by the split hydrogen in water. The solar cells also power the satellites that orbit through the surface of the Earth. This is the reason why there are advancements that people benefit from such as satellite phones and TV, accurate weather forecasting, even the development of the GPS technology and a lot more.

There are a lot of benefits that people can gain from the future of solar energy. You just have to think that whatever you do or however you use such technology for your own good, you must always think of ways to protect your environment first to be able to get the most out of such improvements.

I hope that reading the above information was both enjoyable and educational for you. Your learning process should be ongoing–the more you understand about any subject, the more you will be able to share with others.

PostHeaderIcon You Need a PV System to Generate Solar Energy

Current info about Solar Energy is not always the easiest thing to locate. Fortunately, this report includes the latest Solar Energy info available.

Solar energy has been around for quite some time. In fact, now is the best time to get it if you want to cut your electric bill and do your share to protect the environment.

For that to happen, you will need to buy a PV system. This is designed to reduce or eliminate the amount of electricity you purchase from the utility especially when there could be a price increase in the next few months.

The best part about the PV system is that it generates clean electricity which is clean, reliable and renewable since it does not emit any harmful gases into the atmosphere.

The PV system must be placed in an area that is free from any obstruction otherwise, it will not be able to capture the sun’s rays. A lot of experts say that the south facing roof is best while the east and west is sufficient. If the roof is not available, it can be mounted on the ground.

You should know that PV systems come in various sizes so you should get the one that matches our electrical needs. If you consume about 6,500 kilowatts a year, then a PV system within the 3 to 4 kilowatt range is right for your home. You can measure this by reviewing your past electric bills and making some projections.

Naturally, the size of the PV system will determine the amount of space needed. If you do not use that much electricity, 50 square feet may be sufficient. However, a larger system may require a little over 600 square feet. Just remember that a kilowatt of electricity requires an area of 100 square feet.

How can you put a limit on learning more? The next section may contain that one little bit of wisdom that changes everything.

Solar energy is converted with the help of an inverter since this is what changes direct current to alternating current. You will also need batteries so excess energy may be stored so you can still use solar energy during the evening or during a power outage.

The size of the PV system is also in direct proportion with the cost. Most cost from $9 to $10 per watt and when you include installation, the bill may reach be from $10,000 to $20,000.

The cost of the PV system should not discourage you from investing in solar energy. People who use it are able to get tax rebates and it will also increase the value of your home. With that, the only thing to do now is to call a reputable solar energy provider.

One other thing you should know about the PV system is that this should also be connected to your grid. For this to work, you have to enter into an interconnection agreement with your utility.

This agreement will address the issue with regards to the terms and conditions under which your system is tied up with them. This also includes what is known as net metering which allows you to bank any surplus electricity that your system generates on the electric grid in the same manner that you will be charged accordingly should you consume more electricity than what you have banked.

You need a PV system to generate solar energy. You just need to know what size of a system you require so this can be installed by your solar provider.

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.

PostHeaderIcon Solar energy in households

The sun is a great source of energy. It would be great to use solar energy in your homes especially nowadays when the prices of oil and gas continue to increase. Because of the high fuel and gas prices, more and more people are experimenting on the use of solar energy in their households in their attempts to minimize the costs of basic utilities.

The sun’s energy can be harnessed in different ways depending on how you would utilize the end product. There are so called solar collectors which are placed on the roof tops or used in buildings. The main purpose of these solar collectors is to provide heating and even ventilation for the houses and buildings. These collectors harness the sun’s energy by magnifying the sunlight several times and transferring that heat to air or water. That heated air or water is stored and will provide the building or home heating and hot water whenever needed.

The only problem here is that not all places have equal amounts of sunlight. As you go farther from the equator, the strength of the sun is reduced. But still, this is a much better solution than relying on electric grids which do not reach remote areas. It is just a mater of storing the heat generated from the solar collector properly. For example, some buildings in Sweden utilized an underground storage facility where solar energy is stored resulting to savings from heating the building and their water.

In areas where gas and fuel are out of reach of the pockets of poor communities, residents have to rely on solar cooking for their meals. They use this bowl shaped discs equipped with mirrors or reflectors which directs all the sunlight on the middle where a pot is placed. The same technology is being used in India, Sri Lanka, and Nepal. This serves are a good alternative from conventional fuels like coal, firewood, and gas. They can use these solar stoves during a sunny day and use traditional fuels when the weather is not that good.

See how much you can learn about Solar Energy when you take a little time to read a well-researched article? Don’t miss out on the rest of this great information.

This reliance by communities on solar cooking should encourage more studies on how to make photovoltaic cells cheaper for an ordinary household. At this time, the use of solar cells is not economically friendly for a single household. However, the approach here is to install a series of solar panels which would be shared by the whole community. This could be a good idea depending on your usage, but for basic lighting purposes these could work in small poor communities.

In some areas, community cooperatives have found ways to bring electricity to households out of reach of power grids. In the Philippines for example, a local cooperative provided households loans to enable them to install a basic solar power module which can produce enough electricity for three light bulbs. This ay be laughable in our standards but to these people who have been living all their lives with the flickering light of the candles, three electric light bulbs make a great deal of a difference.

The story is the same in other countries. In Israel, the high costs of photovoltaic cells have clamped down the growth of solar energy in the country. It if fortunate, therefore, that the Israeli government is now providing incentives for households that would use solar energy.

However, according to industry analysts, the costs of solar cells production will go down as the demand increase. Also, most are hopeful that recent discoveries and advancement in technologies will find a way to bring down costs of using solar energy.

Ordinary households using solar energy is an ideal scenario that we should all strive to achieve.

Hopefully the sections above have contributed to your understanding of Solar Energy. Share your new understanding about Solar Energy with others. They’ll thank you for it.

PostHeaderIcon Net Metering and Solar Energy

You can’t help but get into net metering when you decide to invest in solar energy because you sometimes consume more or less than what you actually generate. When you consume less energy, your electric meter spins backward, if you use more then it goes forward.

Net metering is simply a special metering and billing agreement between you and the electric service provider. You are eligible for this if you reside in a residential area and generate some form of energy using solar, wind energy or a combination of both. It also has to be located on your premises and connected to the grid.

For this to work, you need to have a meter capable of moving in both directions. Most meters these days can do that but if your provider wants to use two meters, they will have to pay for it. However, if you enter into a time of use billing agreement, you will have to be one to buy the unit.

The net metering agreement works by letting you use the electricity you generate first before you use what you normally get from your electric service provider. Your meter should show the net which is measured as the difference between the electricity you purchased and what you actually purchased.

The benefit of the net metering system is that it allows you to store electricity when you are not there and then use it the moment you get home. Since there is a law that expands net metering, you can take advantage of it by generating electricity during peak hours and then using it during off peak periods.

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.

Another benefit is the fact that you only pay the net electricity that you use. If you consume below the baseline, you pay less and more if you go over it. If what you use offsets what you normally get from a provider, then you will most likely pay a lower rate.

Since you entered into an agreement with your provider, you will still be billed monthly. This will state the amount of power you generated and the amount you actually consumed. On the anniversary of your agreement, you will be billed for the previous 12 months but you can also request for this on a monthly basis. Keep in mind that you will not be paid for the excess generation of electricity in a given year although some do.

If you want to use solar energy, you have to contact your electric service provider and ask if they offer net metering. When the papers are drawn up, remember that they cannot require you to pay for any meters beyond the bi-directional meter. They cannot conduct any tests or impose any requirements if it meets existing national standards for grid-interconnected systems. Lastly, you don’t have to buy additional insurance or buy power from any of their affiliates.

Net metering is a policy and also an incentive when you decide to use solar energy. This is because you reduce the number of kilowatts used by your electric service provider which in turn decreases the emissions of carbon dioxide into the air.

If you happen to live in either New Jersey or Colorado, consider yourself lucky since they have the best net metering policies in the US. In fact not all states have such a policy in place for people who decide to use solar energy.

If you’ve picked some pointers about Solar Energy that you can put into action, then by all means, do so. You won’t really be able to gain any benefits from your new knowledge if you don’t use it.

PostHeaderIcon The Pros and Cons of Solar Energy

When you’re learning about something new, it’s easy to feel overwhelmed by the sheer amount of relevant information available. This informative article should help you focus on the central points.

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.

Truthfully, the only difference between you and Solar Energy experts is time. If you’ll invest a little more time in reading, you’ll be that much nearer to expert status when it comes to Solar Energy.

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.

I hope that reading the above information was both enjoyable and educational for you. Your learning process should be ongoing–the more you understand about any subject, the more you will be able to share with others.

PostHeaderIcon Solar Energy is the Future

We consume fossil fuels at a greater rate than we have ever had over the past 50 years. That demand is fueled by the increase of cars on the street, the number of planes that take to the air and the number of homes that need electricity. Sadly, we will have depleted these resources by the end of this century which is why we have to come up with other ways to get power and solar energy may be the future.

Solar energy is simply extracting the sun’s energy for power. Just to tell you how powerful the sun is, it can burn scrub lands and give you sunburn if you are out in the sun without any protection. In fact, the Greeks and the Chinese used this to set fire until the 1880’s by Charles Fritts made the first solar cell.

Instead of using a heater to warm up the home, sunlight can be used to control the temperature. You will just need large windows and shades to control the amount of sunlight that will go inside and keep the heat absorbed during the day to remain at night.

Solar energy can also provide warm water as it warms up cold water that passes down through the closed flat panels called collectors.

But solar energy does not only give warmth to the home. It can also be used to help power it which reduces our dependence on non-renewable resources like oil or coal.

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.

This occurs when solar cells are installed on the roof so it will be able to capture as much solar rays as possible and then converts this into electricity. You will need 10 or 12 to capture at least a kilowatt of power and more if you are powering more than just your home.

The only limitation which challenges the use of solar energy is that it can only generate power during the day. The answer to this is to put an auxiliary system in place that will store the energy and kick when the sun is not available. This comes in the form of batteries which will provide power in the evening or a brownout.

Advances in technology have taken solar energy to the next level. NASA uses it to power satellites in orbit, solar panels installed onboard aircraft allow it to fly across oceans while cars can travel speeds up to 40 miles per hour. It is used to power a lighthouse so seafarers will be able to find their way at sea while aircraft can land in an airport in the middle of the frozen desert.

Solar energy is safe for the environment since it does not emit any harmful gases or chemicals into the air. It is a renewable resource that has not yet been fully tapped by a lot of countries which makes it very viable for the future.

But is it the only answer to reduce our dependence on oil? No because solar energy is just one of the options. We can also harness the power of the wind, the wave in the oceans, geothermal heat, hydroelectricity and a lot more instead of relying on coal or even nuclear energy that may harm the environment.

It is something we have to push for the next generation.
