Making A Better Life With Solar Energy

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 infrequently discussed. That could be partly because of the limited use of this source of power. It might also be down to the absence of research in this area. Some have started to study solar electricity health risks and if one researches long enough, one or two guesses are available.

Thermal Solar Energy Health Risks

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 3 basic operations before delivering hot water to your tap 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 electricity systems present few, if any, health risks . Their advantages are that they are much safer than most ordinary fuels or nuclear power – they don’t have any emissions and don’t pollute the air.

PV Panel solar power 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 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 determined that solar electricity health hazards related to manufacturing 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 really slight once the panels are produced and installed on the purchaser’s home. This kind of solar electricity is famous for trustworthiness and low upkeep. The home owner infrequently desires to be concerned in any repairs, and so cuts solar power health risks.

Passive solar power Health Hazards

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 Outline

Solar energy technologies present few, if any, health risks for the final user. Their use can reduce the health issues presented by other power sources, providing cleaner, safer, cheaper energy.
