Solar electricity is the power extracted from the sun’s energy, which is the sunlight. As the sun provides us sunlight absolutely free solar power itself too is a replenish-able, clean and environmentally safe source of energy. With rising worries about using ordinary fuels and rise in air pollution, the use of solar power as an alternative source of energy is fast gaining popularity. By harnessing and using solar power at home, it is actually possible to cut down the cost of electricity charges and intensive use can even make one absolutely independent in terms of power requirements. This is typically because sunlight is available for free just about round the year and the better part is that solar panels and other such solar equipment require little maintenance.

But now, one million buck question arises- that is why, despite so many benefits, are people using solar power only carefully? The answer to this query lies in the proven fact that the solar powers are basically inefficient. To counter this problem, bigger panels need to be installed and this makes using them cumbersome. Also, many people would prefer not to mess with the aesthetic beauty of their residences. Also, the solar cells do not come extraordinarily cheaply. Moreover, there's the inherent problem of unable to work at night and providing little power during cloudy days. However you can learn how to build solar panels from scratch to save lots of money.

With the decrease of traditional fuels, the scientific community has been urged to grasp the pressing requirement to consider upgrading of existing solar cell technology. Now, with continued research and development in those areas, the solar power systems have undergone extreme changes. They have worked out how to make cheaper solar energy panels and also improve their efficiency.

One of the major markers achieved in the solar electricity technology is the invention of solar power cells. They have gone a long way to reducing the size and rocketing the efficiency of the solar cells. In a solar panel, the solar power cells are placed on a steel substrate. Each cell is capable of capturing assorted spectrums of sunlight. The solar photovoltaic panels have overlapped layering of the cells which makes them an efficient source of making power. The new solar solar panels use amorphous silicon thin alloy technology.

This solar photovoltaic panel based totally on the state-of-the-art technology is not that clumsy and can be easily placed on the roof of houses. It is many times more efficient than a regular solar panel. Also, they do not look that bad and can be easily implemented without having an effect on the overall looks of a building.

Another landmark in the road of solar technology is the discovery of photovoltaic shingles. They're fundamentally nothing except solar energy panels which are modified and made into shingles. Photovoltaic shingles can be used as a convenient and cultured substitute for big and voluminous solar panels. They are implemented in the roofs of homes as standard shingles. They are generally black colored and have the appearance of ordinary shingles. And they serve the dual needs of loving your place as well as harnessing solar energy and converting it into electricity for your use. Furthermore, they save you the price of purchasing extra shingles. In a nutshell, they're good looking solar cells.

Experts have claimed the technology of using solar power cells and photovoltaic shingles is a major development in the harnessing of solar power. Research is going on for further development in the solar power technology and you may expect even smaller and better solar energy systems supplied in the near future.

Home owners and parents are often concerned about the potential for electromagnetic fields (EMF) from high voltage lines to cause cancer. What is the truth? The simple answer is that there is no data which proves that electromagnetic fields are harmful.

Numerous studies have been done over the past 25 years evaluating EMF and biological effects. One of the most comprehensive evaluations was the study mandated by Congress, managed by the National Institute of Environmental Health Sciences, over a period of several years (1992-1998). The net result from all these studies is that there is no correlation between EMF and cancers.

Several studies have also tried to create the results in the lab. For example, scientists would expose an animal or a human volunteer to EMF then observe any biological effects. The reports state that the supposed damage to health by power lines could not be reproduced by EMF exposure in the lab.

Furthermore, there have been studies done on people who work close to the lines and these studies show that the health of the individual is good. Specifically, studies have been done on linemen (people who work on power lines as a career), and farmers (who often have large towers in their fields.) These studies show that you can work near or even at these lines for many years without any effects to your health.

In addition to the official health studies of EMF, a brief look at the strengths of electromagnetic fields will tell us that the EMFs from power lines are relatively safe. Scientists have measured the EMF at various distances from power lines of all voltages. This data shows that the energy of the EMF decreases dramatically within a short distance. This data can be summarized by two key facts:

? Within 100 feet of a power line, for the majority of lines, the energy of the EMF decreases by approximately 85%.

? At 500 feet from the power line the EMF becomes negligible, even for the highest voltage lines.

It should be noted that the electromagnetic fields can itself induce electricity in another conductor (including the metal of a tractor). If that happens, a person working nearby can sometimes get a small shock, even when not touching the line. However, those who work on or near these lines say that this small shock is more annoying than harmful.

In summary: numerous data and research exist, all of which demonstrate that EMF from high voltage power lines do not harm humans.
