About Healthy Solar Energy

  1. 1. ==== ====For complete information on everything solar, and to learn more about solar energy, visithttp://solar-panel-s.com/2011/12/about-solar-energy==== ====Solar energy is a potential source of free electricity and water heating. It offers the power to enjoyelectrical power in remote areas of the world. It seems to offer health and safety along with power,but does it?Solar energy health risks are seldom mentioned. That may be partially due to the limited use ofthis source of energy. It may also be due to the lack of research in this area. Some have begun tostudy solar energy health risks, however, and if one researches long enough, a few estimates areavailable.Thermal Solar Energy Health RisksSolar energy health risks are inherent to the design and installation of most thermal energysystems. These are the systems designed to heat water and air for household use.Solar water heaters complete three basic operations before delivering hot water to your faucet oryour heating unit:1. collect sunlight and convert it into heat energy.2. circulate fluids that transfer the heat energy to a storage unit3. store the hot water until you need itThe solar energy health risks with such a system usually occur in the storage units. Some unitsallow for the growth of allergenic molds and fungi.If proper materials are used for the storage unit, however, these solar energy systems presentfew, if any, health risks. Their advantages are that they are far safer than most fossil fuels ornuclear power - they have no emissions and do not pollute the air.PV Panel Solar Energy Health RisksThe solar energy health risks associated with photovoltaic (PV) panels occurs before the panelsare put into use on the consumers home. PV panels are the panels used to collect solar energyfrom sunlight and convert it into usable electricity.The manufacture of PV panels requires the use of toxic materials. Silicon dioxide is mined fromsand or quartzite and reduced with heat to pure silicon. Materials released during refining are themain health risks. Several steps in forming the photovoltaic cells utilize toxic materials. These are

This type of solar energy is known for reliability and lowmaintenance. The home owner seldom needs to be involved in any repairs, and thereby cuts solarenergy health risks.Passive Solar Energy Health RisksPassive solar energy provides safety and health. A new building that maximizes this technologycan reduce energy costs by nearly one half. How?1. Warming indoor air in a house through vertical, slanted windows facing the sun. The windowscapture maximum solar energy from the sunlight.2. Collecting solar energy in adobe or stone walls and floors, and then releasing it into the air asthe temperature falls.3. Collecting solar energy in a sun space, much like a greenhouse built on the sunny side of thehome. This heat is sent into the home with proper ventilation.4. Holding water in black roof tanks until needed, cutting the working time of the homes hot waterheater.5. Using clerestories - rows of windows near roof peaks that catch sunlight and bounce it throughthe building. The sunlight reduces the need for electric lights.In SummarySolar energy technologies present few, if any, health risks for the end user. Their use can reducethe health risks presented by other energy sources, providing cleaner, safer, more cost effectiveenergy.© 2007, Anna Hart.
