Solar energy is a potential source of free electricity and hot water. It offers the possibility of electrical energy in remote areas of the world to enjoy. It seems that provide health and safety with performance, but does it work?
Solar energy health risks are seldom mentioned. This is 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, the health risks of solar energy study, however, and when you search enough, some estimates are available.
Thermal Solar Energy Health Risks
Solar energy health risks inherent in the design and installation of most thermal energy systems. These systems are designed to heat air and water budgets.
Solar water heater fully three basic operations before delivering hot water or your furnace:
First Collect sunlight and convert it into heat energy.
Second circulate fluids that transfer thermal energy storage
Third store hot water until you need it
The risks of solar energy with a health system usually occur in the storage units. For some devices, the growth of mold and allergens.
If suitable materials are used for the storage, however, these solar systems have little or no health risk. The advantages are that it is much safer than most fossil fuels or nuclear energy – no emissions and does not pollute the air.
PV Solar Energy Health Risks
The risks of solar energy health risks associated with photovoltaic (PV) occurs prior to commissioning the consumer’s home. Photovoltaic panels are used to collect solar energy and convert sunlight into usable electricity.
The manufacture of photovoltaic panels requires the use of toxic materials. Silicon dioxide is extracted from sand or quartzite and reduce the heat of pure silicon. Materials are released during the refining process, the most important risks to health. Several steps in the formation of photovoltaic cells using toxic materials. It is sprayed onto the cells, and can be easily inhaled.
It is estimated that solar energy health risks associated with energy production of photovoltaic energy per unit of energy, can be 11 to 21 deaths per quadrillion joules of energy.
Health hazards of solar PV are very easy when the panels manufactured and installed in the house of the consumer. This type of solar energy is known for its reliability and low maintenance. The owner of the house has only rarely participate in all repairs and thus the risks of solar power outages health.
Health risks of passive solar energy
Passive solar energy provides safety and health. A new building, that this technology maximizes the energy costs to reduce almost by half. How?
First Warming indoor air in a house by the vertical windows, tilted toward the sun. The windows of the solar maximum of solar energy capture.
Second Solar energy in the walls of adobe or stone and soil, and then release into the air when the temperature drops.
Third Solar energy in a space of sunlight, like a greenhouse built on the sunny side of the house. This heat is sent home with adequate ventilation.
4th Retention of water in black roof tanks until needed, reducing the hours that the house hot water heater.
5th With skylights – rows of windows near roof peaks that attract the sunlight and bounce through the building. Sunlight reduces the need for electric lighting.
In short
Solar energy technologies present few, if any, health risks for consumers. Their use can reduce health risks from other energy sources, providing cleaner, safer, more efficient energy.
