Renewable sources are the sources that naturally replenish themselves. This is not the case with natural gas. Forms of renewable energy are the sun and wind energy. There is a new source for both at all times.
Five sources of non-renewable energy:CoalOilNatural gasNuclear (uranium)Rainforest timber
Energy from the burning of fossil fuels (coal, oil and natural gas) is non-renewable.
Natural resources
If they are finite non-renewable sources, then sooner or later they are going to run out. The other aspect is the danger of pollution through excessive carbon dioxide or other gases from burning fossil fuels.
