SOLAR ENERGY

What Is Solar Energy?

Healthy Or Costly?

Solar Energy is radiant energy emitted by the sun. It can be produced through the use of a photovoltaic or "PV" cell.A PV cell is a specialized semiconductor diode that converts visible light into direct current. A select few of these cells are able to convert infrared and UV light as well. They are often transparent, and therefore can be obscured from sight by users.

Why We Use It- Solar energy may not be as efficienct as a conventional generator, however devices creating it don't emit toxic chemicals such as CO2, NOx, SO2, and mercury into the environment.- PV cells that produce it are available in sizes ranging from a pocket smart phone charger to an industrial building's generator.- PV cells are considered self reliable, which means there isn't a need to operate them. - PV cells don't require the use of fossil fuels, which are unrenewable and contribute to global warming, unlike coal power plants.

"Energy from the sun converted into either thermal or electrical energy"

Solar Energy Is PriceyToday, the average 5 kilowatt solar panel system may cost you from $25,000 to $30,000. This is just for the installation. If a country can't afford installations, toxic greenhouse chemicals will still be released into the air, and global warming will continue.We're not just talking about cost here. Some PV cells are constructed from toxic chemicals such as cadmium and tellerium. Not to mention they must be disposed of after a certain time frame. If we don't find a way to fix it now, these chemicals will potentially damage surrounding the body systems of surrounding organisms, making it harder for them to survive long enough to reproduce.PV cells are constructed in factories, which produce a lot of pollutants into the environment. Finding a new method of constructing these cells would be ideal, as the pollution will harm an organism's lungs.

Reducing The ConsResearchers and scientists have been monitoring the problem of the release of cadmium and tellerium in the release of a fire, and trying to find a safer substitute. Now, most solar cells are made of silicon, which won't harm organisms that come into contact with it if it's released.Researchers in Australia have been hard at work trying to improve the efficiency of a standard silicon solar panel. Instead of just using one panel, they noticed they could acheive higher efficiency by splitting sunlight, done by using four panels at once.As individuals, there is not much we can do to solve the problems presented above. It will be up to scientists to develop a solar panel that doesn't have to be produced in a polluting factory, has a lowered cost, and has a much higher efficiency rate.

Most PV cellsare made of silicon,which is verysafe and won't be released after a fire.This lack of harmful chemicals will indirectly lower health carecosts.

This Binghamton engineer wants to improve today's solar technology by designing a 'biological solar cell.'

China wants to implement solarpwer in place of its harmful coal generators, but it's too expensive right now.

If a country can'tafford solar panelinstallations, toxicchemicals will continueto be released into theair, and global warmingwill continue.
