The sun does however, revolve about a point in the centre of our galaxy. Taking entire solar system with it at a speed of 220 km/s. This period of orbit takes 225 million years. The sun revolves at about once every 25days at its equator and up to 30 days near its poles.

Answer:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were released in the explosion, such as the kinetic energy and potential energy of the pieces, as well as heat and sound, one will get the exact decrease of chemical energy in the combustion of the dynamite. Classically, conservation of energy was distinct from conservation of mass; however, special relativity showed that mass is related to energy and vice versa by E = mc², and science now takes the view that mass–energy as a whole is conserved. Theoretically, this implies that any object with mass can itself be converted to pure energy, and vice versa, though this is believed to be possible only under the most extreme of physical conditions, such as likely existed in the universe very shortly after the Big Bang.
Explanation:
Conserving energy can lower heating, cooling, lighting, and other costs. Environment. Energy has to be created somehow. Be it coal, nuclear, water, or oil, all energy is created at the cost of the environment or the air we breath. Saving energy is one way to help protect the environment for future generations.
