Sun
All the energy that we use on earth originally comes from the sun. While the sun’s surface is about 5000 degrees, its core temperature may well be millions of degrees. In this infernal environment atomic nuclei rush criss-cross colliding incessantly. Many stick to each other of fuse causing nuclear fusion. The result of this is solar radiation. Life on earth exists thanks to this solar radiation. Many hundreds of millions years ago plankton, dead marine animals and plants sank to the bottom of coastal waters, where they rotted in low-oxygen water. Sand and clay covered the layers of semi-decayed remains pressing them together over the millions of years. The high pressures and temperatures converted this organic material into coal, oil and natural gas. In an attempt to bridge millions of such years of production, biofuels are being produced from special agricultural crops. Alternatives exist such as energy generated from wind, water, nuclear energy … and of course solar energy.
