A renewable resource is a resource which can be used repeatedly since they are replaced from time to time through natural processes. Such resources can be classified into two types:
1. Conventional renewable resources
2. Non-conventional renewable resources
1. Conventional renewable resources
Water
Water is a renewable resource and has a life cycle which should be properly maintained. However, its mismanagement and overuse may create shortage of water.
Forest
Forests are an important part of our planet. They help to regulate climatic conditions, provide timber, medicinal plants, fruits, and house a variety of plants and animals. Due to large scale deforestation, we are losing vast areas of forests rapidly. To compensate the loss, afforestation should be done to ensure that the forest cover remains the same.
Wildlife
Animals are a renewable resource since they have a life cycle and reproduce. However indiscriminate use and loss of habitat is threatening the wildlife of Earth. Proper management and public awareness is therefore necessary to maintain wildlife as a renewable resource.
2. Non-conventional renewable resources
Solar energy
It is the prime source of energy for the biological world. Solar radiations are abundant in many countries which can be tapped and converted to electrical energy using photocell.
Wind energy
Wind blows at a high speed in many locations of the world. The wind energy can be converted to electrical energy using suitable technology such as wind turbines.
Tidal energy
Waves and tides at sea can be converted to electrical energy using a natural or artificial waterfall which rotates a turbine in order to produce electricity.
Atomic energy
Radioactive elements are utilized to harness energy in atomic reactors. The enormous heat produced is used to generate steam which is used to run turbines in order to produce electricity.
Geothermal energy
Steam from hot springs is used to generate steam which is utilized to run turbines in order to produce electricity.
