why do we study the solar system?
Because it is there. :^)
Different people have different reasons.
One driver is the quest to know whether we are alone in the universe or if there are others like us out there, wondering some of the same thoughts as we do.
It is fascinating to know that we are not the only planet in the universe -- that there are other planets. And if there are other planets, how are they similar and how are they different to our Earth? And, could life arise on these planets? And do these other planets give us any idea of our own planet began and how it changed over time?
By studying the movement of the planets, we understand more about gravity and how it behaves as a force.
So many other reasons ... so little time to write.
Solar energy is a potential source of free electricity and water heating. It offers the power to enjoy electrical 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 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 Energy Health Risks
Solar energy health risks are inherent to the design and installation of most thermal energy systems. 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 or your heating unit:
1. collect sunlight and convert it into heat energy.
2. circulate fluids that transfer the heat energy to a storage unit
3. store the hot water until you need it
The solar energy health risks with such a system usually occur in the storage units. Some units allow for the growth of allergenic molds and fungi.
If proper materials are used for the storage unit, however, these solar energy systems present few, if any, health risks. Their advantages are that they are far safer than most fossil fuels or nuclear power - they have no emissions and do not pollute the air.
PV Panel Solar Energy Health Risks
The solar energy health risks associated with photovoltaic (PV) panels occurs before the panels are put into use on the consumer's home. PV panels are the panels used to collect solar energy from sunlight and convert it into usable electricity.
The manufacture of PV panels requires the use of toxic materials. Silicon dioxide is mined from sand or quartzite and reduced with heat to pure silicon. Materials released during refining are the main health risks. Several steps in forming the photovoltaic cells utilize toxic materials. These are sprayed on the cells, and can readily be inhaled.
It is estimated that solar energy health risks associated with producing PV panels per unit energy may be between 11 and 21 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 Energy Health Risks
Passive solar energy provides safety and health. A new building that maximizes this technology can reduce energy costs by nearly one 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 risks for the end user. Their use can reduce the health risks presented by other energy sources, providing cleaner, safer, more cost effective energy.
