Making A Better Life With Solar Energy
Solar electricity is a potential source of free water and electricity heating. It offers the power to enjoy electric power in remote areas of the planet. It appears to supply H&S with power, but does it?
Solar energy health risks are seldom mentioned. That may be partially due to the limited use of this source of energy. It may also be due to the lack of research in this area. Some have begun to study solar energy health risks, however, and if one researches long enough, a few estimates are available.
Thermal solar electricity Health Hazards
Solar energy health risks are inherent to the design and installing of most thermal energy systems. These are the systems engineered to heat water and air for household use.
Solar water heaters complete three basic operations before delivering hot water to your faucet or your heating unit:
1. Collect daylight and change it into heat energy.
2. Circulate liquids that transfer the heat energy to a storage unit
3. Store the hot water till you need it
The solar electricity health risks with such a system generally happen in the storage units. Some units make allowance for the growth of allergenic molds and fungi.
If correct materials are used for the storage unit these solar power systems present few, if any, health hazards. Their benefits are that they’re much safer than most carbon-based fuels or nuclear power – they haven’t any emissions and don’t pollute the air.
PV Panel Solar Energy Health Risks
The solar electricity health risks related to photovoltaic ( PV ) panels happens before the panels are put into use on the customer’s home. PV panels are the panels used to gather solar electricity from daylight and change it into serviceable electricity.
The produce of PV panels needs the utilization of harmful materials. Silicon dioxide is mined from sand or quartzite and reduced with heat to pure silicon. Materials released during refining are the main health hazards. Many steps in forming the photovoltaic cells use noxious materials. These are sprayed on the cells, and can quickly be breathed.
It is ascertained that solar electricity health hazards related to producing PV panels per unit energy might be between eleven and twenty-one deaths per quadrillion joules of energy produced.
Solar energy health risks from PV panels are very slight once the panels are produced and installed on the consumer’s home. This type of solar energy is known for reliability and low maintenance. The home owner seldom needs to be involved in any repairs, and thereby cuts solar energy health risks.
Passive solar electricity Health Hazards
Passive solar power provides health and safety. A new building that maximises this technology can reduce energy costs by just about half. How?
1. Warming indoor air in a house through vertical, slanted windows facing the sun. The windows capture maximum solar energy from the sunlight.
2. Collecting solar energy in adobe or stone walls and floors, and then releasing it into the air as the temperature falls.
3. Collecting solar energy in a sun space, much like a greenhouse built on the sunny side of the home. 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 home’s hot water heater.
5. Using clerestories rows of windows near roof peaks that catch sunlight and bounce it through the building. The sunlight reduces the need for electric lights.
In Summary
Solar energy technologies present few, if any, health hazards for the consumer. Their use can reduce the possible risks to health presented by other sources of energy, providing cleaner, safer, cheaper energy.
