Photovoltaic (PV) solar power eases the usage of diminishing natural resources such as oil, coal and gas. Today, we live in an exceptionally demanding environment where the use of energy is growing at an alarming rate. It is vital to preserve the earth’s fossil fuels and other natural resources, not only for a healthier environment but also for the ability of future generations to meet their own needs.
PV solar power systems minimize the amount of waste production. For example, the entire process of converting coal to electricity produces a lot of dust, discarded solid waste, spillages of toxins and harmful emissions, as well as wasting energy, heat, land and water.
Pollution from non renewable fuels is inevitable. Emissions such as Sulphur Dioxide, Nitrogen Oxide and Carbon Dioxide all can have a negative effect on farming, people’s health and water. Ecosystems are also at risk of being destroyed. Furthermore, pollutants from kerosene used for lighting purposes is reduced with the use of solar power systems, as well as the decrease in use of diesel generators for the production of electricity.
PV Solar power systems produce electricity without giving off carbon dioxide. One PV Solar system can offset approximately six tons of CO2 emissions over a twenty year life span.
Solar power improves energy efficiency and is therefore very beneficial for Third World countries. Solar power electricity reduces the costs of conventional power for built up cities, and is cheaper for industrial and commercial purposes to run their operations. This leaves the use of PV systems to generate power for most of the developing world's population in rural areas.
Small dry cell batteries are used for appliances such as portable radios and flashlights, but are most commonly used in rural areas where there is lack of electricity .However, the lead from these disposed dry cell batteries can have damaging effects on soil and water. Solar power reduces the need of using disposable dry cell batteries and therefore decreases the risk of contamination.
