Important Facts about Solar Energy
As the population’s opinion is changing about sources of energy, it is very important for everyone to understand some of the basic facts about solar energy so that they can appreciate the endless opportunities it brings to us. Because solar energy is one of the most ecologically friendly energy resources available today, it is easy to see why it is becoming the most popular alternate
Here are some of the key facts of how solar energy all got started.
We are not the first of humans to want to utilize the sun for energy; many ancient civilizations realized that the sun harnessed unlimited power. Many years later, Leonardo da Vinci began working on the idea of heating water through an industrial solar energy machine. Science was forever changed by the sun as well when the French scientist discovered the photovoltaic effect on
electrolytic cells. Centuries after da Vinci’s solar water heater model was developed, it was finally patented by an inventor in 1894, which kick-started the whole solar energy trend.
Another man, in 1913, then built the world’s first solar thermal power station. This solar thermal power station helped run a 65 horsepower engine that was used to pump around 6,000 gallons of water in the Nile River. The last kick in the solar energy’s history happened in the year 1954 when the world’s very first modern photovoltaic solar cell was created by the Bell Laboratories.
Here are some very interesting facts about the technical aspects of solar energy.
There are only two main types of solar devices; there are active devices and passive devices. The active solar devices use the photovoltaic cells as energy, while thermal energy is used in passive solar devices. The most common energy transformation devices available today use photo voltaic systems because they can directly turn solar cells into electrical energy. Because of their
extremely high specific heat energy qualities, thermal based passive devices hold solar energy through the use of molten salts. As the technology in solar energy continues to increase, it is becoming estimated that by the year 2060 we will be using solar energy to power 33% of the entire world’s power needs.
The attraction to solar energy only continues to grow as time passes. The possibilities are limitless when it comes to the endless energy of the sun. The fact of the matter is, solar energy is both one of the easiest sources for energy to harvest as well as the cleanest; solar energy is one of the few resources known today that does not emit greenhouse gasses. Along with being one of
the cleanest forms of energy, solar energy is also one of the easiest energy resources to maintain; a solar energy system can be in place for around thirty years before any maintenance is needed. As you can see, it all boils down to being efficient and being conscious of the environment, which is why solar energy is so important to us today.
