we often hear about the terms "renewable" energy, but according to some Physics laws, energy is something that couldn't be created or destroyed. How could energy be "renewable" then? I also know that there is high-grade energy and low-grade energy. When energy is changed from high-grade to low-grade, it's unlikely to reverse the process. When wind energy is collected by the facilities it is then finally converted into heat energy, which is not possible to go back.
By the way, can the existing non-renewable energy so far last for another 100 years for the world
