Renawable resources are the resources that are repeinished  by the environment over relativity short periode of time. this type of resource is much more desairable to use because  often a resource renews so fast that it will have regenerated by the time you've used it up
example think of a ice cube maker in fridge .as u take some ice out,it takes a little more time to refill the bin but not a very long time at all.
Any plant that are grown for use in food and manufacture products are also renewable resources.trees for timber,cotton for clothes,and food crops such as corn and wheat,can all be replanted and regrown after the harvest is collected.
Bio fuel is also a renewable resource
