Power of the SUN! The sun is the star that dominates our big star with a temperature to hot. The sun is the star that dominates our solar system. The amount of energy emitted by the sun radiation is fairly constant. This energy production is generated deep within the sun. Like a star, the sun is composed of 71% hydrogen, 27% helium and 2% other elements. In the center of the sun's density is 150 hours of water and the temperature is about 16 million Kelvin, which causes the nuclei of individual hydrogen atoms undergo nuclear fusion (in other words joined together). That means the sun is a very big star with a temperature too hot.
WHERES IS THE ENERGY COME FROM? Energy can be found in many things and takes many forms. There is the potential energy of objects at rest that makes them move if the resistance is removed. It is the kinetic energy of moving objects. The molecules that make up all matter contains a large amount of energy. Energy can also travel in the form of electromagnetic waves, such as heat, light, radio and gamma rays. Your body uses metabolic energy to his last meal as you read this. Energy flows constantly changing shape. If you take your energy metabolism and rub your hands together, they have made the metabolic energy into mechanical energy. His hands were warm. That's part of the mechanical energy is converted into heat energy.That means that the energy benefit of all parties and in different ways as well as energy goes
FOR WHAT ENERGY IT IS USED? Energy is used to do all kinds of work, from moving around, to growing food, to having fun. Humans have invented many ways to save their own energy and improve their life by using energy in the world around them to do work. For example, horses were used to enable men to travel further and faster. Tools such as bows and spear throwers were developed to enable man to hunt for food more effectively. Over the last 300 years the Industrial Revolution has changed the way humans work and live. Now we make machines, vehicles and electronic devices to do our work for us while we sit back and think of even more ways to make our lives easier!
WHAT ARE THE BENEFITS FOR ENERGY? One of the most important benefits of renewable energy is the fact that it’s non-polluting. And of course as the name tells us it is renewable and does not use resources that can never be replaced. Renewable energy has a much lower environmental impact than conventional sources of energy. But there are other advantages to using renewable sources of energy.
