Summary:Renewable energy sources viewed from the entropy principle. The two fundamental laws of thermodynamics - the energy conservation law and the entropy growth law - are valid also for the Earth and its biosphere, including the man's civilization. The first law tells us that there is no need to be concerned about energy - its amount is always kept constant. What changes is the quality of energy (and matter). The thermodynamical measure of quality is entropy. The second law of thermodynamics says that entropy of any isolated system can only grow (or stay constant). Historically the sign in the definition of entropy is chosen so that growth of entropy means decrease of quality. Earth is not an isolated but closed thermodynamical system: it receives Sun radiation of high quality and sends into Space long-wave radiation of lower quality
