Yes, for oil and natural gas. For coal, possible not.
oil but that's not going to last much longer either, electricity is the next big thing although there is still alot of wood around.
Build and use wind power plants
Build and use solar power plants.
Enough to last 25o years.
i think sprearmint last's much much longer.
it is because the coal is made from woods
About enough to make us last till 2030.
