The sun is the most important presumption for life on earth. Nothing would be able to live in our world without the sun. No plants, no animals and no humans would have been developed without our nearest star. You can say that the sun is the engine for the evolution.
It isn’t strange that the sun has been worshipped, admired and used by people since the birth of mankind. Man has had big use of the sun in its development, from the ancient Greeks who were among the first to use the sun for heating of water to the modern solar cells of the present day.
The sun, creator of energy forms
The sun isn’t just the mother of all life; it also creates almost all of the other energy forms. Most of the energy forms are just indirect solar energy.
Waterpower exists because the sun makes the oceans to become steam so that the water can flow back as rivers, with enormous power. Wind power exists because different parts of the atmosphere absorb different amounts of solar heat and then comes into collision with each other. All biological fuels gets as you know their energy using photosynthesis and all fossil fuels, like oil and coal, are biological material that has been transformed to fossil fuels under certain circumstances. As a matter of fact, you could say that nearly all energy is solar energy. However, in this assignment we shall explain a little about solar energy that hasn’t been transformed.*A1, C5
Reason
We chose solar energy as our assignment because we believe that it’s still not fully exploited with an enormous potential. We wanted to examine the economical facts of solar energy, the environmental circumstances and we wanted to know more about how it works.
Sunlight is theoretically an unbeatable way to heat houses, stores, offices and factories because of its security, its environmental aspects and that it’s probably going to be the least expensive way to gain energy.
