Author: Nobody enjoys swimming in cold water, which is why most people installing a pool opt for a swimming pool heater to keep the temperature more comfortable. Several options exist, including gas, heat-pump and solar power. Which option is chosen by the pool owner will be determined by their budget.
Understand, most swimming pool heaters operate on the same premise. Water is pumped from the swimming pool, through the heater and back into the pool where the heated water raises the temperature level of the pool water. A thermostat installed on the line into the pump records the temperature of the water in the pool and stops pumping until the temperature drops below a pre-set temperature.
How the water is heated is what determines the cost. There are two variables to consider when deciding the type of swimming pool heater is best for your pool. The initial cost and the annual operating cost. Some may offer cheaper installation costs, but prices of utilities and the climate in the area, may make them expensive to operate during the season.
Installation And Operating Expenses
Of the three main types of swimming pool heater, gas, either natural or propane, is the cheapest for initial installation. For comparison purposes an example of a 15 foot by 30 foot kidney shaped pool will be used. A gas swimming pool heater will cost roughly $1,200 and another $500 for installation. A homeowner can usually install a swimming pool heater themself, but it is highly recommended that connections for gas and electric be left to a licensed professional.
A heat pump swimming pool heater is more expensive to install, about $3,900 including installation and a solar powered swimming pool heater will run about $3,000 with installation. Their operating costs are what sets them apart.
A gas swimming pool heater will cost about $1.20 to realize a dollar’s worth of heat. On an average, it’s expected to cost between $1,000 and $1,500 per season to operate on propane. Depending on the price of natural gas in the area, it could cost about 50 percent less.
A heat pump swimming pool heater, on the other hand will cost about 20 cents for $1,00 worth of heat, bringing the annual cost of between $250 to $500 per year, which can offset the initial cost. A solar powered swimming pool heater will cost about $30 to $75 in electric to operate the pump required for water circulation, but not for the power itself.

Imagine a much different world. What kind of economy would we have if we could produce more power than we consume? Think of the advancement of technology if we built a free energy generator. This machine could power our cities and our homes. Many people say that free energy generating machines are already in use. Others say that the technology is suppressed for various reasons.
If we could generate free energy we would never be paying those expensive gas prices. We could all be riding our very own electric powered car fueled by electric generators powered by a free energy machine.
What may some problems be if we did use a perpetual motion generator to power our homes and streets? Maybe all the electric companies would go out of business. The economy would lose 100s of billions of dollars because there is no need for gasoline or enormous space polluting electric power plants. s
We could make space stations and power them to extreme velocity. Imagine it there was no limit to making enormous amount of energy.
Professor John Searl proudly claims to have built a perpetual motion machine that could generate unlimited power potential. It involves magnets.
If we used alternative free energy our skies would clean up. The water would be cleaner. People these days always want the environment to be clean. Who wants to live in a dirty polluted earth? We may not even be able to live on this earth if we keep emitting toxins that fill our atmosphere.
Many companies now days are constructing wind generators that power houses. Wind generation is a free energy since there is no cost to run it excluding cost for maintenance. Solar power is another free energy that we derive from the sun. It powers our houses and/or electric devices and maybe even our cars!

This just shows the importance of night time lighting. However, there is one kind of lighting that is most economical and eco-friendly. Guess what? It is solar powered lighting.
Today, there has been an increase in the awareness on solar products, and more and more individuals and companies are investing on solar power lighting. Such solar lighting applications are employed for various needs such as solar street lights, solar billboards, commercial lighting etc. Let us a have a glance at some of these and their significance.
Commercial Solar Lighting and Solar Powered Billboards
Solar Billboard Lighting gives you high output solar sign lighting for commercial purposes at cost effective prices. Specially designed kits are available for lighting solar powered billboards with solar powered lighting fixtures; these kits are designed to offer best value for money. Even if you are in a remote location where it would be otherwise expensive to set up electrical supply for a billboard lighting system; solar billboard lighting can fill the void. Solar Lighting is also available for other commercial applications such as in business complexes, parking spaces, etc. These commercial solar lighting is available in various sizes and features to suit specific requirements of the clients. These are specially designed to operate in all weather conditions. Even if it is a rainy day with the sun hiding behind the clouds, the solar lighting system has the essential arrangements to operate with backup supply.
Solar Sign Lights
Solar Sign lights are great for landscape lighting, commercial, and real estate lighting. This includes parking space, street lighting, engineering lighting and more. These commercial sign lights can light up your company or real estate dwelling signs through out the night. Also, solar sign lights kits are simple to use and easy to set up. And you don’t have to spend time doing ground wiring or spend heavy on maintenance and electricity bills. With a solar sign light, you are actually doing a life time investment for your lighting requirements, and you are doing it the smart way.
Solar Street Lights
Solar Street Lights make use of light detectors that allow the automatic switching on when it goes dark, and automatic switching off at the crack of dawn. Given that they use the sun’s energy for the lighting, Solar Street Lights can run on and on even when the conventional power sources fail.
Solar Security Lights
Another significant use of solar lighting is in security systems for protecting private or government owned landscapes. This comes across as a low energy cost option for maintaining safety with security lights. These lights usually employ a motion detector to activate the light upon every movement in its range. Again, these solar security lights require no ground wiring, all it needs is the sun for getting the power.
With the solar way, we do have a promising future in terms of lighting. There is nothing as smart as using the sun’s energy to light up the night as well. It’s high time people started using more of solar lighting for their homes and industries, as this option is not only cost effective, but is also easy to set up and good for the environment. So go ahead, get your own solar lighting system and enjoy soothing lighting without having to worry about electricity bills.

For years scientists have been finding newer and better methods that we can use solar power in our ordinary lives. Several of us understand that it is able to be harnessed through special technology to power the electricity, water, and heat within our houses. Though it is rare to discover anybody that uses this because it is so costly.
Still, there are other more simpler devices that utilize this exact same construct. These have been created for the same purpose as residential solar energy – to save money on electricity and to help the environment at the exact same time. These simple machines include contrasting methods to add light to your garden.
Outdoor Solar Lights
If you have a garden that you made yourself and that you are proud of then you will wish to show it to anyone who comes for a visit. In this garden you might have arranged a couple of your favorite trees, flowers, and possibly even a pond.
Outdoor solar lights are great to use round your garden to light it up when dark comes and give you the opportunity to delight in your creation. In the front yard you can always use these to light up the walkway to your front door. They are more handy to utilize then other lights because they do not need any wires that have to be immersed underground.
Solar Lantern
Certain people need to bring flashlights or lanterns when out camping. It is the only way that they can see what they are doing and to find their way around safely. The solar lantern is one of the most common forms of simple solar power and is easier to use then kerosene lamps because they do not let loose damaging gases.

Data loggers are stand alone devices, gathering and organizing a large amount of data over long spans of time. While they are sometimes part of a data acquisition system, data loggers can also be independently used for getting information reliably and unattended.
One aspect of the loggers is that they usually have a time stamping mechanism and can match data received to the time it was logged. If the logger has a built in real time clock, sometimes there is a bit of time drift however, the specifics of a logger’s time drift are published and should be taken into consideration when choosing a machine.
Some equipment has very simple inputs and can only accept one or two channels of information. Other more sophisticated machines have intricate combinations of channels that involve multiple inputs for sensors as well as specific information sources. Modern versions can interact with external computer programs and are even able to automatically present collected information on a web page for remote collaboration between users. This ability to utilize data over the web has been very useful for the medical profession.
Because data loggers are stand alone machines, they need some sort of on board memory to store collected data. While earlier models used magnetic tape, punched paper tape, or even charts printed on reams of paper, modern loggers use RAM, flash memory or any one of the many memory options available currently.
Sometimes loggers are left for months in hostile environments to collect long term data. Usually battery power is used to keep them running, though some machines use solar power to assist the batteries. This limited power supply means that the loggers are very efficient in their power use, especially compared to a regular computer.
The operating system as well as the structural make up of these machines is extremely dependable. Since a lot of the time the loggers are operating without human supervision, they have to be completely reliable. The instruments are designed so that as long as they have power they will not fail to log data for any reason.
A data logger is dependable, accurate, and independent. These work horses of the scientific and medical professions have been assisting humankind for decades, and will continue to do so as long as we need reliable, well organized information.

Conserving earth’s energy is nowadays seen more seriously than observing Earth Day on April 22 and involves taking initiatives of generating renewable energy. As the name suggests, this particular type of energy once produced is less prone to peril and can be reused in a multifarious ways. Two compelling reasons why creating using such alternative energy is found momentous, currently –
1. First of all, renewable energy which is often marked as green energy sources are usually considered cleaner than using fossil fuels that induces emission of carbon dioxide. Therefore, this green energy helps alleviating release of greenhouse gases that is directly linked to grave threat to earth like global warming.
2. Fossil fuel gases are on the brink of getting wiped out from the earth. Moreover, it is difficult to predict certainly when the time will come to witness supply of oil will surpass increasing demand. Though, many have forecast that within decades or so, oil production is expected to peak and meet exceeding demands. Therefore, by alternating our dependence upon renewable energy will limit increasing demands for oil based energy. In other words, we can avert social and economic mayhem when the time will arrive when the oil production will hit the highest point.
So, What Type Of Renewable Energy Can We Produce?
Amongst multitude of renewable energy sources, we can consider or rely on the following because of their widespread usage and advantages receivable from those –
Solar: Solar power or solar energy tops the list of sources of generating renewable energy. Because it is an established fact that solar power sourced by the sun is unlikely to be running out, is touted to be a great source of green energy. Solar energy can be obtained through south-facing windows and heat up rooms. Otherwise, solar energy can be collected by using special equipment that amasses energy to convert into electricity.
Wind: Wind is another source to harness renewable energy is sizable quantity. Tall and scenic wind turbines found mainly in wide, vacant areas are used to collect the power of wind to transform into electricity. Renewable energy can be produced at the fastest pace from wind energy and it is also clean and green.
Other sources that are considered good and green way to produce abundant renewable energy include water, geothermal and biomass.

Article Source: Why Is It Necessary To Alternate To Producing Renewable Energy?
Solar power is one of the biggest achievements that we have established in the world of technology. Hundreds of individuals have put their time and energy into learning out how it operates and how it is able to help us with our ordinary lives. They have learned that it has the power to be used to light up houses, heat them, and provide them with the water they need.
Numerous of us are intrigued by the technology that is solar power – but hardly any of us realise exactly how it is able to hold all of the energy that the solar panels pull in. All of the energy is from the sun – which is why you cannot collect it during the evening hours when the sun is covered from our view.
Because of this special devices were constructed that would have the power to hold it for hours on end and with little troubles. There are thermal mass devices that are able to store the electricity in the form of heat for average temperatures or for particular seasons.
These devices are more usually produced with materials that are able to withstand high heat. This includes earth, stone, and water. Some of the most peculiar and well produced devices have the power to lower peak demand, lower the heating and cooling demands, and alter the time it is supposed to be utilised during the off peak hours.
The phase change materials are also used for thermal storage and are some of the more low-priced types. They are more common utilised on residential homes where they are simpler to get a hold of and to install. These materials include Glauber’s salt and paraffin wax. The first Glauber’s salt solar power heating device was utilized in 1948 in a home in Massachusetts.
Molten salts are utilised to hold solar energy at high temperatures. This is essential for storage medium and are more noteworthy because they are not as expensive and have the ability to hold up against some of the more intense heat temperatures. There are also off-grid PV devices that use rechargeable batteries to hold in excess quantities of electricity.

New solar power design research conducted at the Massachusetts Institute of Technology (MIT) could lead to higher powered, more affordable solar panels.
With the help of computer simulations and various advanced chip-manufacturing methods, a team of physicists and engineers at MIT have discovered new ways of getting greater efficiency from photovoltaic solar cells.
In the experiment, the team applied an anti-reflective coating to the front, and a innovative series of multi-layered reflective coatings and a defraction grating – a closely spaced array of lines – to the back of ultra-thin silicon films to increase the cells’ power by up to 50%.
With the help of the carefully designed layers on the back of each cell, light is bounced around longer inside the thin silicon film, allowing it more time to transfer its energy into an electric current. Without those coatings the light would be reflected straight out of the cell.
One of the team members, Peter Bermel, a post-doctoral researcher in MIT’s physics department explained that it is critical that any light entering the layer should travel through a long path in the silicon. But what they have not figured out yet is how long that path has to be to ensure maximum absorption of electrons to produce the electric current.
The test was started by running thousands of computer simulations, testing variations of the thickness of the silicon, spacing of the lines, and the amount and thickness of reflective layers on the back. These simulations were then used to optimize efficiency and power output.
According to Lionel Kimerling, the project manager and Thomas Lord Professor of Materials Science and Engineering: “The simulated performance was remarkably better than any other structure, promising, for 2-micrometer-thick films, a 50 percent efficiency increase in conversion of sunlight to electricity.”
Once simulations were complete, they were confirmed by actual lab-scale tests, where graduate student Lirong Zeng was given required to refine the structure and make the silicon cell. As predicted, the experiment was a success and sparked considerable industry interest.
The work done so far was just the first step toward manufacturing an affordable, improved solar cell. Now all that is needed is some fine-tuning through more simulations and lab tests, and more work on the materials and manufacturing process.
According to Kimberling, if the solar business stays strong, we can expect this new technology to be ready within the next three years. Bermel added that, “the potential for savings is great, since the high-quality silicon crystal substrates used in conventional solar cells represent about half the cost, and the thin films in this version use only about 1 percent as much silicon.”
To evaluate its business potential, the project was selected by the MIT Deshpande Center for an “i-team” study. Here it was concluded that this thin film solar cell technology could provide considerable benefits in both manufacturing and electricity production, for uses ranging from remote off-grid to dedicated clean energy.
While no single project is likely to minimize the cost of solar cells, this type of innovation takes us one step closer to making solar power design competitive with fossil fuel and nuclear grid electricity.

Far from being a new technology the history of the use of solar power obtained from the sun is as old as time itself. Harnessing the sun’s power is a natural way in which to convert that power into some useful energy, from a plant using photosynthesis, to modern photovoltaic cells. One cannot begin to explain how humans have harnessed this most common of energy sources without first referring to the ancient civilisations.
It would appear that the ancient Greeks and Romans actually built solar power design features into their buildings to utilise the sun’s rays for heating, both water and the interior. But consider even earlier cultures who used solar power to light up dark interiors even by reflecting the suns rays in very specific directions. Solar power has also been used to bring about great victories over superior foes. There is a legend of the Trojans using a large concave glass to concentrate the sun’s rays on the wooden ships of their Achaean enemies, which subsequently burst into flames.
However, the modern research into solar power has not focused on such destructiveness. The first ‘solar’ houses were built after WW1 in the industrial Ruhr area of Germany. Although not at all popular at first, there did continue to be some study of them carried out in the USA, but the technology did not catch the public’s imagination at that time due to the relative cheap cost of carbon fuels and the mistaken belief of their inexhaustibility.
In 1933, designer George F Keck designed a house made completely of glass for the Century of Progress Exposition in Chicago. He found that it was warm inside on bright but cold winter days despite there being no provision for heating. Keck began incorporating south facing windows in his designs for other houses which increased his knowledge of the abilities of solar power. In 1940 he was able to design the very first passive solar house in the USA for a developer called Howard Sloan, who in turn built a number of such houses throughout the 1940’s. His efforts in this area certainly influenced a number of other builders in the post war building boom and he is credited with the first use and popularising the term ‘solar’ to describe these houses. Unfortunately there was misunderstanding which lead to houses being built facing away from the southern exposure required for the solar power to work. This did have an effect on their popularity and contributed to a decline in public interest in the technology by 1950.
It took the 1973 oil crisis to enliven the debate about alternative technologies for fuel and energy. Solar power was seen as a forerunner of the new wave of alternative reusable and sustainable energy sources and still is today. Recent developments in the efficiency of photovoltaic cells have meant that solar power technology is being used in all manner of things and less sunlight is required to produce enough energy to both power and store for later release. There is little doubt that solar power is here to stay and can only become more accessible as the technology matures.

Article Source: Solar Power – A Brief History
The United States produces and consumes a lot of energy- more than any other country in the world. Its supply enables American society to carry out the many functions inspired by the industrial revolution- allowing factories to manufacture products that will pave roads, build houses, clothe people, gas our cars, keep stores open, and ensuring that people are comfortable in their homes. It takes a tremendous volume of energy to sustain American life. In recent years, however, environmental scientists have started influencing American thought. Along with other highly-industrialized societies, the way in which we use energy cannot go on forever. National security and possibly human health are at issue.
Currently, most of the US’s source of energy comes from petroleum, coal, and natural gas. A mere 15% is supplied by nuclear power, hydroelectricity, and other renewable and eco-friendly energy sources such as wind and solar power. The leader in energy consumption is the industrial sector- factories that produce raw materials such as aluminum, petrochemicals, and steel are especially energy-intensive. However, transportation, residential, and commercial sectors are not far behind.
As the US population continues to grow, the demand for electricity is going up. Coal and natural gas are the main sources of electricity for residential consumption, growing in a large part due to space heating and lighting. Americans also use 20,680,000 barrels of petroleum per day to fill up their cars, and although that amount is expected to fall in the short-term due to current economic conditions, it may not be long before the economy bounces back and consumption increases again.
With public opinion moving positively towards more environmentally-cautious energy practices and many public officials promoting the use of renewable energy sources, further development of power plants that reduce carbon emissions and are powered by a renewable source seem to be in our future. Until then, Americans can actually do more in their private lives to help lower energy consumption, with the first step being that they learn how to measure the amount of energy they are using within their homes on a day-to-day basis.
The simplest way of doing this is by home electric meters, usually located on the side of a house. The meter reads the electricity being emitted in a given moment. In addition, home watt-hour meters can be purchased for only $150 and involve a quick installation by an electrician, which provide the service of calculating total kWh usage. There are even small devices that enable a conscientious consumer to find out the wattage of a single appliance, such as a window air-conditioning unit. By plugging the appliance into the device, which then plugs into the wall, he/she can find out how many watts are being used at a given moment as well as total kWh usage; all for less than $40.
Once Americans are able to see the effects of their energy-use habits, they may be compelled to reduce the amount of unnecessary electric power use through a range of proactive steps from adopting a wider indoor temperature range to installing better insulation. They can also lower petroleum use by practicing less aggressive driving techniques, driving at lower speeds, utilizing cruise-control, and, most effectively, carpooling.
Energy-use adjustments can also be easily made in the commercial and industrial sectors. For instance, the lighting in retail stores, schools, offices, and other workplaces tend to be a very wasteful component of commercial use. More efficient lighting as well as the elimination of over-illumination can greatly reduce the waste of electricity in these settings. In the industrial sector, the recycling of waste material and the use of cogeneration equipment for electricity and heating can significantly cut energy use, as it has shown to do in the recent past.
Environmental-caution is increasingly becoming a more welcomed attitude in modern American society. This is reason enough for many Americans to jump on board to the cause. In addition, aside from social ramifications, the idea of energy conservation can also potentially lead to increased financial capital, improved national and personal security, continued human comfort, and of course, environmental value.

For centuries we have used the sun’s natural energy to our advantage. For example, it has been used in ancient times to provide natural lighting in temples, for photosynthesis and natural heating for growing crops, to desalinize and purify water, and it has been magnified and intensified to heat thermal power plants.
So, how can solar power be used on a smaller scale at home as clean source of energy?
Basically, there are four main ways how to solar power your home:
Passive Solar Design:
To think that Americans consume up to 50% of their energy to heat, ventilate and air-condition their homes, a large amount of money and energy could be saved by using passive solar design at home.
Passive solar design is the strategic use of the sun’s energy to heat, light and ventilate your home naturally. For example, having a home that faces the sun, that has large, low-emissivity windows, and that is built from heat-retaining materials will tend to be naturally warmer in winter.
And like the Romans used the sun to light up their temples, careful placing of windows and mirrors in our homes can increase natural lighting, helping us reduce the need for electric lighting.
A natural air conditioning solution would be to plant deciduous trees on the sun-facing side of your home. This would provide cool shade in summer, but allow warm sunlight though in winter.
A solar chimney can be installed for ventilation, where the air in the chimney is heated by the sun and rises, causing fresh, cool air to rush in through the home and up the chimney.
Solar Cooking:
Solar cooking is the cleanest and cheapest way to prepare food. Although it is widely used in third world African countries, where fuel and electricity is not readily available, there is no reason we cannot use it during summer at home.
A solar cooker is made from a series of reflective panels in a parabolic shape that focus the sunlight on a box or pot, in which the food is cooked. It usually caters for up to five people, and can make a variety of boiled, roasted and baked dishes.
The one drawback of solar cooking is that it tends to take three to four times longer to cook food in. But if you weigh that against the unlimited power savings and its portability, having a little patience is not that bigger deal.
Solar Water Heating:
Solar water heating has a number of uses, and thanks to technological developments, modern solar water heating systems can be used at home to completely replace conventional boilers or geysers.
As cold water is pumped through a solar collector, the pipes absorb the sun’s energy, and heat the water, which is then stored in an insulated tank for later use. Usually the water can get so hot that it has to be mixed with cold water before it can be used.
Solar Electric Power:
Also known as photovoltaic power, many homes are starting to make their own power at home with solar electric panels. These panels are made up of small silicon cells and need to be directly aimed at the sun to be most effective.
As the sun’s rays penetrate the solar panels, electrons in the cells become charged, creating a current that is stored in deep-cycle batteries. When electricity is needed, the stored power is passed through an inverter to change the DC to AC, which can then be used to power various household appliances or connected to the grid for net metering.
Other than providing you cheap, clean renewable power, solar electric panels have become affordable and simple enough for anyone to install at home. In fact, with the right information it is possible to make your own solar power for under $200, as compared to getting a professional installation for a couple of thousand dollars.
With these four ways on how to solar power your home, there is no need for you to rely on the utility companies or the government for heating and lighting at home. Right now it is very possible for us to use solar power at home. It is just a matter of everyone having the determination, energy consciousness and environmental awareness to take action and harness the sun’s free, natural power.

These days green is the new black! That’s right everyone across the United States are discovering new ways to save the planet by creating cars that release less toxic fumes, making new things from recycled materials, and by powering our homes in new ways. One of the more popular methods to living ‘green’ is through the use of solar power.
Solar energy has the ability to give us cheaper if not free electricity to our homes through the use of solar panels. However, before you jump on the band wagon and go out and try to start this new power trip there are a few things you should know. There are some people who believe there are many negatives to solar power.
Many people believe that thermal solar energy has many health risks when it is used to heat water and the air in their homes. This can happen when it has not been set up properly or the manufacturer made errors when producing it.
Majority of solar water heaters were built to do three things. Give people hot water, obtain sunlight and convert it into heat energy, and to circulate the fluids that can transport heat energy to the storage system as well as store hot water till someone needs it.
If it is unable to store the water properly it can cause fungus and molds to grow making anyone who drinks or uses the water sick. To make sure that this does not happen you can make sure that the units used to store the water have been built from materials that are made to prevent this.
PV solar energy also as health risks that you need to be careful of. PV (photo-voltaic) panels require millions of silicon dioxide in order to be used. That number is lowered when they are exposed to heat. The materials that are released during the refining process will increase the rate of toxicity and can affect your health. This is one of the more serious negatives of solar energy that is responsible for eleven to twenty one deaths per each quadrillion joules of energy that are created.
But do not let this deter you completely. Study up on the different types of solar panels and the negatives as well as the positives. You might find that they are worth it in the end.
There are many Negatives of Solar Energy that people consider before investing in it. Before you make your decision consider the Benefits of Solar Energy and how to Harness Solar Energy.

If there is one policy every first world nation can get behind, it is the movement away from fossil fuels and towards renewable, clean energy. While debates may rage about the viability of clean coal, everyone is in agreement that solar and wind technology will be at the forefront of this movement. Let’s take a look at just a few of the benefits of solar power technology and why it is clearly the energy of the future.
First and foremost, solar power technology is limitless. One of the industry buzzwords we have all been hearing more and more about lately is “peak oil”, the belief that the world’s oil supplies are in decline and that we, as a civilization, are due to run out of fossil fuels sooner rather than later. When it comes to solar power technology, we won’t ever have to worry about hitting our peak. Even in traditionally rainy climates like the Pacific Northwest, solar power technology is flourishing, thanks to super sensitive solar panels that capture energy even during overcast days and more efficient batteries that can hold more charge for longer periods of time. It is safe to say that the old excuses that used to be used to marginalize solar power are now obsolete.
Speaking of antiquated myths about solar power, a company in California recently unveiled a solar panel that could sell for less than any other panel on Earth. Nanosolar recently exhibited a panel that puts solar energy on par with coal manufacturing plants on a per-kilowatt basis. One of the most enduring arguments against solar power technology has always been the cost. The world has been waiting decades for a truly cost effective solar panel and now, thankfully, we don’t have to wait any longer.
While more and more countries build nuclear plants to deal with the spiralling demand for energy, there doesn’t seem to be similar plans in place to deal with all of the toxic nuclear waste those plants will produce over their lifetimes. Solar power technology, on the other hand, is completely clean, with no residues, waste or byproducts of any kind. Until someone comes up with cold fusion, solar is far and away the most environmentally friendly energy source in the world.
Thanks to improving technology, solar is also extremely portable. There are rollable solar panels that can be unplugged and taken with you on a trip and there are even tiny solar panels that you can attach to your backpack and use to charge your mp3 player while you walk. This is one area in which solar has wind power beat.
Finally, solar power can create more energy than a single family needs. Just like wind, extra power from solar panels can be fed back into the power grid, providing clean, free energy to people throughout an entire community.
While other forms of power may offer a stopgap as we wean ourselves off of fossil fuels, the power of the future is clearly solar.
