For whatever the reason, we have a giant and extremely dense sphere of hydrogen in the sky called the Sun. How lucky for us this is, since the Sun is constantly undergoing Nuclear Fusion and cranking out megatons of solar energy on a regular basis.
This solar energy arrives to Earth as electromagnetic radiation, where it is absorbed and utilized in the biosphere in numerous ways. The Sun and solar energy it emits is arguably the most essential element to our existence.
Electromagnetic (EM) radiation comes in many different wavelengths. We describe EM radiation based on its wavelength with Gamma rays being the shortest, and Radio waves the longest. Earths solar energy falls in the middle, composed of infrared, ultraviolet, and visible light waves. This is a good thing because all wavelengths between Gamma rays and Ultraviolet rays are harmful to humans and most other things on Earth.

Solar energy plays a primary role in all biological and thermal interactions on the Earth. With the presence of carbon dioxide, water, and solar energy, plants are able to produce energy through a process called Photosynthesis.
The Earths natural landscapes, they absorb solar energy and produce heat. It is the heat absorbed by mountains and plains that create local wind patterns. It is the heat absorbed by the oceans that creates the famous currents. Solar energy is responsible for thunderstorms, tornadoes, and hurricanes. It melts the mountain snows which form many of our rivers.
And so it is no surprise that solar energy is at the root of almost all physical processes that occur on Earth. Without this valuable resource life as we know it would not exist.
The effects of solar energy are wide spread and dynamic. The Earth is one big giant bio-energy machine all fueled by the same thing " that big Nuclear Furnace that rips across our sky once per day and which we call the Sun.
Thinking about it like that, we should probably all wake in the Morning and give thanks to the Sun. It is the single item in our existence we take most for granted. What if the Sun disappeared for one day? Just think of the mayhem and chaos this would create. And think of all the solar energy that would be lost all over the world.
With the recent advances in materials and industry, we now find ourselves with some new inventions for working with solar energy. It is now possible to make electricity directly from sunlight in a photovoltaic device. We can harness solar energy in absorption and concentrating collectors and store the heat.
The modern home can benefit greatly from solar technology, and the implementation has only just begun. Whether retrofitting your house, or building a new home, harnessing solar energy can bring tremendous savings and true energy independence. As a side benefit, we can feel good about lessening our impact on the environment.
How much can we rely on these new technologies to power our daily needs? Does making power from solar energy really save in the long run? How difficult are solar energy systems to integrate, and what types of technologies are the best? We pondered these very questions ourselves, and decided to share some of the answers.
