The Source of Power
Solar energy powers everything on the Earth, directly or indirectly. Without the sun no life could exist. (Think plants.) There is another use for solar energy, however: it can be turned into electricity using photovoltaic cells or solar panels. Using solar energy this way has many positive effects on a number of different factors. Solar energy can also be used passively to bring about positive effects such as increased health.
Reduces Pollution
Using solar power to produce electricity reduces pollution. Although pollution is still created during the manufacture of the solar panels required to turn solar energy into electricity, no pollution is created whilst they operate. This has many positive effects on the planet, reducing the strain on natural ecosystems, saving natural habitats from oil companies and helping to stop deforestation for charcoal.
Stabilize Economy
The economy at the moment is based upon oil. This valuable resource is spread unevenly throughout the world, causing tensions to rise between countries who possess oil and those who do not. In contrast, solar energy is available to the entire world. It is unlimited and free. By switching our main power provider to solar energy, the economy would not fluctuate with the price of oil.
Increased Home Safety
Fossil fuels such as oil and gas are volatile and dangerous. A small crack in piping to a building can be devastating to both property and lives if ignited. The use of gas can also produce CO2 or carbon monoxide which can kill over long exposure. Solar energy is not unstable, and there is no risk of explosion or poisoning from its use.
Populate Remote Locations
Remote locations can be powered by solar energy allowing people to live in remoter locations without the need of large utilities being installed. Solar cells can be constructed anywhere and angled to make best use of any sunlight. They do not require large amounts of cable or a factory to process the power. They can be used to get power to people who otherwise would not have access to electricity.
Passive Use
Solar energy does not need to be harnessed through solar panels to have a positive effect on the way we live. Sunlight is a major contributory factor to heat. By placing windows to the south and tilting them to make the best use of available sunlight in the area, buildings can be heated without any need of artificial heating. Thermal mass can also be used with solar energy to provide heat. By using a dense material for walls and floors and making them double the usual thickness, they can store heat and radiate it back into the room on an evening. This reduces the need for other heating means saving money and reducing pollution.
Health Benefits
SAD or Seasonal Affective Disorder is a serious condition that is currently being researched. It is believed to be linked to a lack of light exposure and a deficiency in vitamins received from sunlight. The symptoms of SAD are a change of appetite, decreased energy, depression, difficulty concentrating and feelings of anxiety. A large problem with SAD, is that people are working in buildings that are artificially lit for most of their time. To help avoid his, light tunnels could be installed in buildings to funnel solar energy into an otherwise dark portion of a building, helping to relive the effects of this disorder.
