The sun is a gigantic ball of fire located at the heart of the Solar system. Being the closest star to the earth and acting as a massive source of energy, the sun emits heat, light and other forms of useful and harmful radiation to our planet. It is a well-known fact that millions of living organisms on earth depend on the sun for their survival. It is one of the earths major life sources. We are inevitably plugged in to this amazing energy spring and it is quite challenging to imagine the existence of life on earth without the presence of the sun.
There are numerous solar energy facts that we need to understand for us to further appreciate the suns value to our planet. These solar energy facts are summarized below
The suns heat and light is emitted through electromagnetic radiation
Not all of the suns energy reaches the earths surface because some are reflected back to space by the layers of the earths atmosphere
Humans have harnessed solar power even during the ancient times
Without the sun, life will not be able to exist on earth
The energy from the sun that the earth receives varies according to location and weather condition
Solar power can still be harnessed and used even in the most desolate and coldest places on earth like the north and south pole
Solar power is one of the most reliable alternative sources of energy and it is also the most environment-friendly because it has zero carbon emissions and deadly byproducts
It can be harnessed, converted or modified, and distributed for domestic and commercial use
Harnessed solar energy can be used for heating and cooling in solar architecture, processing of water to make it potable, electrical lighting systems, water heating, and solar cooking
It can be used to run solar-powered gadgets like calculators, watches, radios, and vehicles like cars and airplanes
In Europe, pools are heated using solar power
Solar energy is harnessed actively by means of a solar panel or photovoltaic panels
Solar energy can also be harnessed indirectly by modifying the architecture design of an edifice to have better natural illumination and air circulation, selecting and using materials that maximize the suns light, and orienting a structure to more efficiently capture or receive the suns rays
Certainly it is essential to learn about solar energy facts in order to understand the power of this type of energy better, and thus be able to harness it further and use it to our advantage.
