The idea of using solar energy to power our homes and institutions has been with us for quite some time now. As people continue to conduct further research, more and more uses of solar power are coming up. One of these is the use of solar energy to power garden lights. Although the idea is noble as it allows one to enjoy the numerous benefits associated with solar energy, the question that many people ask themselves is: is the light generated bright enough?

How It Works

Before I tell you whether the light generated is enough, I think it is important that we first understand how the garden lights function in the first place.

To assemble solar powered garden lights, one needs a couple of things, the main ones being a solar cell, a NiCad battery and an LED light source. During the day, the solar cell charges the NiCad battery which lights up the LED during the night.

The Light Amount

The LED used in making the garden lamp is the low-watt LED. The reason for this is that the lights are meant to be energy efficient and this means that they will consume less energy. The end result is that the light that will be produced by the low-watt LED is likely to be less than the amount that will produced by the power consuming traditional garden lights.

It should however be understood that the reason why these lights are not as bright as their traditional counterparts is not because manufactures are unable to come up with better products. No. After all, manufactures can simply make larger batteries and larger solar cells. Unfortunately this can turn out to be bulky and may require more wiring, hence beat the very purpose of solar powered garden lights in the first place.

The good news however is that less light does not necessarily mean that it’s little light. The brightness of solar powered garden lights is enough to create the ambience that you will need for your garden. In addition to this, more research is being done on these lights so as to make them brighter.

The debate about the use of solar energy in our homes, industries, offices and even cars has raged on for quite some time now. However, there does not seem to be a clear path towards achieving greater usage of solar energy. Opponents of solar energy claim that the energy source is expensive and impractical. On the other hand, proponents of solar energy argue that investing in solar energy is investing in the future.

But just what is so important about solar energy?

A Clean Energy Source

One of the most important reasons why people are proposing for greater investment in solar energy is because it is clean. This means that it does not emit harmful gases or chemicals when it is being produced. Using energy from oil, coal, or nuclear power plants requires that you sacrifice a clean environment for energy. On the other hand, using solar energy allows you to have a clean environment and energy at the same time.

A Renewable Energy Source

Another reason why you should use solar energy in your house or office is because it is a renewable energy source. This means that you won’t have to worry about running out of stock. Unlike oil, coal, uranium and other natural sources of energy which can easily get depleted, the sun will continue to be there for as long as the earth continues to exist.

No Political Interference

You and I should also continue to pay greater attention to solar energy because it is not susceptible to political interference especially from other countries. When your country relies on resources from other countries to get energy, you can get stuck once the relationship between the two countries gets thorny. Prices of items like oil also fluctuate greatly when there are security concerns in oil producing countries and so on. However with solar, you won’t have to worry about this.

You might be thinking about reducing your power bills, acting on global warming, or even freeing yourself from bondage of international oil markets. Well, you are not alone. Solar energy might be expensive to set up, but the long-term benefits definitely outweigh the short-term costs.

To many people, the desire to switch from the potentially catastrophic nuclear energy and the unreliable oil to a cleaner and less expensive source of energy is big. If you are like me, you are probably wishing that we could get a magical pill that will be able to solve the entire energy problem. One of the things that people – and maybe you – consider to be a magic pill is solar energy.

But just what are the pros and cons of solar energy?

Pros

Clean energy. In this era of global warming and a polluted environment, any source of clean energy is welcome. Solar energy does not emit harmful gases or chemicals as oil and nuclear power do.

Renewable. The other advantage of solar energy is that for as long as the sun exists, then solar energy will continue to be available. Unlike other oil and energy from nuclear power plants, solar energy is renewable.

Affordability. Apart from the fact that it is clean and renewable, solar energy is also advantageous because it is affordable in the long term. Although the initial costs can be quite prohibitive, you will not be required to pay power bills and hence it can turn out to be cheaper in the long run.

Cons

Despite all the advantages listed above, solar energy has also its own disadvantages which have caused it to be distanced by many.

High start-up costs. The installation of solar panels, inverters, batteries and so forth can be quite high for an individual person or small organization to make. It may therefore make sense for many people to go on paying their power bills as the entry costs are not so high.

Unreliable weather conditions. Solar panels get their energy from the sun. Therefore, if the sun refuses to shine as bright as you would want it to, the consequence will be that the power produced will be small and the energy insufficient.

Regardless of the disadvantages, there is still a great movement towards generating power solar panels. Huge investments are being made so as to come up with better solar panels.

Regardless of whether you have a car, you must have been affected by fluctuating oil prices at one time or another. In addition to unreliable prices oil is also one of the greatest pollutants in the world. For this reason, governments and companies are working hard to come up with oil substitutes and one of these substitutes is solar power.

You may have heard about solar powered cars and you might be thinking that that it is one of the most impractical things ever. You probably believe that you will never drive a solar powered car in your lifetime. Well, guess what? If that is what you are thinking, you are wrong!

Their History

People have used solar energy in their homes for quite some time now. However, the use of solar energy to power vehicles was a concept that was explored in the 1970s when the world was experiencing a severe oil shortage. However, the interest in solar powered cells was not pursued intensively by car manufacturers. The interest in the cars has not been consistent and has largely depended on oil prices.

How It Works

Well, you may be wondering how solar powered cars work. The main function of a solar panel is to receive light from the sun and then convert the light to electricity. The electricity is then used to power the car and make it run.

Practicality

From the above explanation of how solar powered cars work, one might think that the process is quite simple and even wonder why such cars are not being produced and sold. Unfortunately, a car that is powered by solar power will require having an extremely light frame and body so as to make it light enough. Again, such a car would have to stay in the sun at all times. This means that putting the car inside the parking lots and the shades will not work. Therefore, these vehicles are just made for demonstration purposes and as hobbies (by individuals.)

Now

Reading the above article it might be right to conclude that solar powered cars are only meant for the future. That would actually have been the case were it not for the creativity of the Toyota Company of coming up with the Toyota 2010 model which has a solar powered moonroof. The energy from the solar panel will then be used to power the air conditioner and help reduce your gas bill.

Though existing technology is still expensive and which means that the cars will not be so widespread, we hope for better things ahead. As companies continue make huge investments into solar powered cars, you and I will son be cruising in our neighborhoods with fully solar powered cars.

The Christmas season is one of the most hectic holidays in a year. The demands for gifts and the parties all over can cause you to spend a lot of money during this time. However, your money is not just spent on gifts and parties, but also on another must-have Christmas prop – the Christmas lights.

Do you know anything about Solar Christmas lights?

Well, if you don’t, you should. The solar Christmas lights are a great invention for those who would like to save on unnecessary energy costs. It’s even more fascinating if you are a nature lover or someone who cares about the environment.

How They Work

To have your Solar Christmas lights working, you need to position your solar panel in a place that receives maximum sunshine exposure. The power that is generated by the solar panel is then used to light up low wattage LED Christmas lights.

Effectiveness

Since these solar Christmas lights are designed to consume less energy compared to the tradition Christmas lights, they tend to produce less light than their traditional equivalent. This means that you must be ready to give up some “fun” associated with extra bright lights. However, the light that comes from solar powered LEDs is enough to make your Christmas eventful.

Cost

The cost of any item is usually one of the most important factors that you will consider before you buy anything. The same should be the case with solar powered Christmas lights. A set of solar Christmas lights goes for between $20 to $40. And although they are slightly more expensive than the traditional solar lights, you will not have to worry about power bills once you set them up.

Disadvantages

As already mentioned, one of the biggest disadvantages solar Christmas lights is that they have got a very low output due to the low wattage of their LEDs.

There is also a problem of unreliable sunshine. December is one of the months that has the least sunshine, yet that is the month that hosts the Christmas season. This means that the problem of low wattage bulbs is compounded by the lack of sunshine.

All in all, if you want to enjoy a unique Christmas, try out the solar Christmas lights. With increased technology, it is not only expected that prices will come down, but also that the LEDs will be more effective in the amount of light that they will produce.
