Solar energy is a potential free electricity and water heating source. It has the power to take advantage of electricity in remote areas of the world. It seems to offer health and safety with power, but is it?
Rarely health risks of solar energy are mentioned. This may be partly due to the limited use of this energy source. It may also be due to the lack of research in this area. Some have begun to study the health risks of solar energy, however, and if you study long enough, some estimates are available.
Solar Thermal Risks Health
Solar energy Health risks inherent in the design and installation of most thermal energy systems. These systems are designed to heat water and air for domestic purposes.
Complete solar water heater three basic operations before delivering hot water to the faucet or your heating unit:
1. collect sunlight and convert it into heat energy.
2. Fluids circulate that transfer of thermal energy storage unit
3. store the hot water until you need it
The health risks of solar energy with a system of this type usually occur in the storage units. Some devices allow the growth of mold and fungal allergens.
If appropriate for the storage unit materials are used, however, these solar systems pose little or no risk to health. Its advantages are that it is much safer than most fossil fuels or nuclear power – no emissions and no air pollution.
Risks photovoltaic solar panel Energy Health
The health hazards associated with solar photovoltaic (PV) occurs before panels commissioned in the consumer’s home. Photovoltaic panels are panels used to collect solar energy from sunlight and convert it into usable electricity.
The manufacture of photovoltaic panels requires the use of toxic materials. Silicon dioxide is extracted from sand or quartzite and reduced with the heat of pure silicon. Material released during refining are the main health risks. Several steps in the formation of photovoltaic cells use toxic materials. They are sprayed on cells, and can be easily inhaled.
It is estimated that the health risks of solar energy associated with the production of solar panels per unit of energy can be between 11 and 21 deaths per quadrillion joules of energy produced.
The risks of health solar photovoltaic panels are very light once they are manufactured and installed in the consumer’s home panels. This type of solar energy is known for its reliability and low maintenance. The owner of the house rarely have to participate in all repairs, and thus reduces the risk of health solar energy.
Risks of Passive Solar Energy Health
Passive solar energy provides safety and health. A new building that maximizes this technology can reduce energy costs by almost half. How?
1. Warming indoor air in a house by the vertical windows, tilted toward the sun. Capture window to the maximum solar energy from sunlight.
2. The solar energy or walls of adobe and stone floors, and release into the air as the temperature drops.
3. The solar energy in an area of sun, like a greenhouse built on the sunny side of the house. This heat is sent home with adequate ventilation.
4. The retention of water in black roof tanks until needed, reduction of working time in the water heater in the house.
5. Using skylights – roof windows ranks near the peaks that attract sunlight and bounce through the building. Sunlight reduces the need for electric lamps.
Solar technologies have few, if any, health risks for the end user. Its use reduces the health risks presented by other energy sources, providing cleaner, safer, cost-effective power.
