In nature, some of the energy can be recycled to reduce, not because of the long-term use of. This kind of energy, we called renewable energy, such as solar energy, wind energy, hydro energy, bio energy and so on. In nature, some energy is not recycled, with a bit less. This energy, we call the non renewable energy, such as coal, oil, natural gas, nuclear fuel etc.. As shown in the table.
Of course, the difference between renewable energy and non renewable energy is relatively. For example, we put the coal, oil and other fossil fuels as non renewable energy, is not to say that they absolutely can not "regeneration", but because of their very long regeneration period, so, we call the non renewable energy.
